      هناك الكثير من الخيارات الرائعة من 240 مم إلى 270 مم. يمكنك أن تصبح خفيفًا جدًا مع العديد من هذه العدسات، أو الحصول على فتحة قصوى ساطعة مع بعض خيارات f/5.6. ما يلفت انتباهي حقًا هو Fujinon W 250mm f/6.7 - فهي خفيفة نسبيًا ولها فتحة قصوى رائعة تبلغ f/6.7، بينما توفر مساحة واسعة للحركات. إنها عدسة قديمة بعض الشيء وهي ذات طبقة واحدة وليست متعددة الطبقات، ولكن هذه مقايضة جيدة، خاصة بالنظر إلى السعر.

      إن أبرز الميزات البصرية - الحديثة، والمتعددة الطبقات، وذات دائرة صورة كبيرة - هي Docter Germinar-W 240mm f/9 (على الرغم من صعوبة العثور عليها) وRodenstock APO Sironar-S (على الرغم من أنها كبيرة وثقيلة جدًا). تستحق عدسة Fujinon 240mm f/9 أيضًا الإشارة إلى سهولة حملها وبصرياتها، لكن ضع في اعتبارك أنها لا تقدم الكثير من الحركات.

      بالمناسبة، عندما أذكر في الجدول أن العدسة مُحسّنة للتركيز البؤري القريب، فهذه سمة متأصلة في التصميمات المتماثلة أو شبه المتماثلة. وهذا لا يعني أن العدسة سيئة عند التصوير اللانهائي، وخاصة عند التوقف، يمكن أن تكون ممتازة عند التركيز على مسافة. ومع ذلك، مع هذه العدسات ذات التكبير 1:1، سيتم التخلص تمامًا من العديد من انحرافات العدسة



      There are lots of great choices at 240mm through 270mm. You can go ultralight with many of these lenses, or get a bright maximum aperture with some f/5.6 options. One that really catches my eye is the Fujinon W 250mm f/6.7 – it’s relatively light and has a nice maximum aperture of f/6.7, while offering extensive room for movements. It’s a bit of an older lens and is single-coated rather than multi-coated, but that’s a good tradeoff, especially considering the price.

      The optical standouts – modern, multicoated, and with a large image circle – are the Docter Germinar-W 240mm f/9 (though it’s very hard to find) and the Rodenstock APO Sironar-S (though it’s pretty big and heavy). The Fujinon 240mm f/9 also deserves a mention for its portability and optics, but keep in mind that it doesn’t offer much in the way of movements.

      By the way, when I mention in the table that a lens is optimized for close focus, that’s an inherent characteristic of symmetrical or near-symmetrical designs. It doesn’t mean the lens is bad at infinity, and especially upon stopping down, it can be excellent when focused at a distance. However, with such lenses at 1:1 magnification, many lens aberrations will be completely eliminated

        حوالي 300 مم، يمكنك العثور على عدد كبير من العدسات مقاس 8 × 10 التي من شأنها أن تلبي أي احتياجاتك. تعتبر عدسات سلسلة Rodenstock Sironar-S وSchneider APO-Symmar على نطاق واسع من أكثر العدسات كبيرة الحجم وضوحًا على الإطلاق، كما أن Nikkor W هو منافس قريب جدًا يتم بيعه مقابل جزء صغير من السعر. وفي الوقت نفسه، إذا كنت بحاجة إلى شيء أصغر، فإن Fujinon A 300mm f/9 أو Fujinon C 300mm f/8.5 هي خيارات رائعة. وفقًا للميزانية، سأحصل على Nikkor W إذا كنت لا تمانع في الوزن، أو Schneider G-Claron 305mm f/9 إذا كنت تفعل ذلك (ليست عدسة متعددة الطبقات، ولكنها حادة جدًا وبها مساحة كبيرة للحركات).

        أحب استخدام عدسة G-Claron 305mm f/9 لالتقاط صور قريبة، وفي هذه المرحلة تعد واحدة من أفضل العدسات المصححة عند هذا البعد البؤري. تم تحسين معظم الكاميرات الأخرى (باستثناء Fujinon A 300mm f/9) للأهداف البعيدة، بشكل عام في أي مكان بدءًا من التكبير حوالي 1:10 إلى التركيز اللانهائي.

        Around 300mm, you can find a ton of lenses for 8×10 that should meet any needs you have. The Rodenstock Sironar-S and Schneider APO-Symmar series lenses are widely considered some of the sharpest large format lenses ever made, and the Nikkor W is a very close competitor that sells for a fraction of the price. Meanwhile, if you need something smaller, the Fujinon A 300mm f/9 or Fujinon C 300mm f/8.5 are great choices. On a budget, I would get the Nikkor W if you don’t mind the weight, or the Schneider G-Claron 305mm f/9 if you do (not a multicoated lens, but pretty sharp and with tons of room for movements).

        I like using my G-Claron 305mm f/9 for close-up photos, at which point it’s one of the best-corrected lenses at this focal length. Most of the others (apart from the Fujinon A 300mm f/9) are optimized for distant subjects, generally anywhere from about 1:10 magnification to infinity focus.

            لديك العديد من العدسات للاختيار من بينها في نطاق الطول البؤري 355-360 مم لـ 8 × 10، لكنها جميعها غير ملائمة بعض الشيء. الخياران الوحيدان خفيفا الوزن هما Fujinon A 360mm f/10 وSchneider Tele-Xenar 350mm f/10 - كلتا العدستين الباهظتين، خاصة Fuji، ولا تتمتع عدسة Schneider حقًا بقدر الحركات التي أفضلها 8 × 10.

            كما هو الحال مع 300 مم، تعتبر عدسات سلسلة Rodenstock APO Sironar-S وScheinder APO-Symmar هنا من أفضل العدسات ذات الأداء البصري على الإطلاق، وأسعار Schneider منخفضة جدًا هذه الأيام. لكن السؤال هو إذا كنت تريد حمل شيء ثقيل إلى هذا الحد.

            إذا كنت تريد حلاً وسطًا جيدًا، فقد تكون عدسة Graphic Kowa 360mm f/9 هي أفضل رهان لك. إنها عدسة متناظرة ذات طبقة واحدة تزن أقل من معظم الخيارات الأخرى هنا. إنه ذو حجم خيط مرشح معقول وهو لطيف وحاد عند التوقف، على الرغم من أنه أقل قليلاً على النقيض من بعض الخيارات الأخرى.

            ويجب أن أذكر أيضًا أن هناك العديد من العدسات الأقدم مقاس 355 مم (غالبًا ما يطلق عليها عدسات مقاس 14 بوصة) والتي قد تتمكن من العثور عليها في الغالق. يمكن أن تكون هذه خيارات رائعة، لكن معظمها يعاني من نفس المشكلات المتعلقة بالوزن المرتفع والسعر. هناك خياران بارزان هما Goerz Red Dot Artar مقاس 14 بوصة وKodak Commercial Ektar مقاس 14 بوصة، وكلاهما مشهوران بالتصوير الفوتوغرافي للصور الشخصية، على الرغم من أن Goerz لا يحتوي على مساحة كبيرة للحركات عند التركيز البؤري اللامتناهي.

            لست متأكدًا من سبب احتواء النطاق 355-360 مم على مثل هذه الخيارات غير الملائمة للعدسات مقاس 8 × 10 مع الأخذ في الاعتبار أنها قريبة جدًا من البعد البؤري "العادي". ولكن في بعض الأحيان هذا هو ما يحدث في التصوير الفوتوغرافي ذو التنسيق الكبير. ربما يكون من الأفضل استخدام عدسة مقاس 300 مم و450 مم بدلاً من ذلك، إلا إذا كانت لديك ميزانية لشراء Fujinon A 360 مم f/10 أو لا تمانع في حمل شيء ثقيل جدًا.

            Fujinon A 360 مم f/10 مع 8×10 Fuji Velvia 50


            You have several lenses to choose from in the 355-360mm focal length range for 8×10, but they’re all a little awkward. The only two lightweight choices are the Fujinon A 360mm f/10 and the Schneider Tele-Xenar 350mm f/10 – both expensive lenses, especially the Fuji, and the Schneider doesn’t really have the amount of movements that I’d prefer on 8×10.

            As with 300mm, the Rodenstock APO Sironar-S and Scheinder APO-Symmar series lenses here are considered some of the best optical performers ever made, and the prices of the Schneider are criminally low these days. But the question is if you want to carry something that heavy.

            If you want a good compromise, the Graphic Kowa 360mm f/9 may be your best bet. It’s a single-coated, symmetrical lens that weighs less than most of the other choices here. It has a reasonable filter thread size and is nice and sharp when you stop down, though a little lower in contrast than some of the other options.

            Also, I should mention that there are many older 355mm lenses (often termed 14” lenses) that you may be able to find in a shutter. These can be great choices, but most of them suffer from the same issues of high weight and price. Two notable options are the 14” Goerz Red Dot Artar and 14” Kodak Commercial Ektar, both of which are popular for portrait photography, although the Goerz doesn’t have much room for movements at infinity focus.

            I’m not sure why the 355-360mm range has such awkward options for 8×10 lenses considering that it’s so close to the “normal” focal length. But sometimes that’s how large format photography goes. It’s probably best to stick with a 300mm and a 450mm lens instead, unless you have the budget for the Fujinon A 360mm f/10 or don’t mind carrying something quite heavy.

              Additional Notes Rare. Optically excellent. Too heavy to make much sense, especially given the Fujinon C and Nikkor M lenses above.



              على الرغم من أن الخيارات تتضاءل في هذه المرحلة، إلا أن النطاق 420-480 ملم لا يزال لديه بعض الخيارات الجيدة لـ 8 × 10. إن Fujinon C 450mm f/12.5 وNikkor M 450mm f/9 هما جوهرتان مطلقتان. حتى أنني أشهد على استخدام Nikkor Q من خلال تجربتي الخاصة - فهي عرضة للتوهج قليلاً، وقد قمت مؤخرًا بالتبديل إلى M، لكن العدسة مقاس 450 مم Q لا تزال واحدة من أكثر العدسات حدة التي استخدمتها على الإطلاق.

              أما بالنسبة للخيارات الأخرى، فلن أشتري العدسات الأثقل في هذه القائمة بغض النظر عن السعر. إن Fujinon 450mm f/12.5 وNikkor M 450mm f/9 جيدان جدًا بحيث لا يمكن الحصول على أي شيء آخر. وفي الوقت نفسه، تحظى بعض العدسات الأقدم مقاس 420 مم (أو العدسات مقاس 19 بوصة) بشعبية كبيرة في تصوير الأشخاص، بما في ذلك عدسة Fujinon L المذكورة أعلاه.


              Although the options are slimming at this point, the 420-480mm range still has some good choices for 8×10. The Fujinon C 450mm f/12.5 and Nikkor M 450mm f/9 are two absolute gems. I’d even vouch for the Nikkor Q from my own experience – it’s a little prone to flare, and I did recently switch to the M, but the 450mm Q is still one of the sharpest lenses I’ve ever used.

              As for other options, I wouldn’t buy the heavier lenses in this list regardless of price. The Fujinon 450mm f/12.5 and Nikkor M 450mm f/9 are just too good to get anything else. Meanwhile, some older 420mm lenses (or 19″ lenses) are popular for portraiture, including the Fujinon L lens listed above.

                Additional Notes Modestly rare. Optically good. True circle of illumination is enough for 16×20 film at narrow apertures (at least 650mm). A barrel lens that can be machined into a Copal #3 or Ilex #5 shutter. I prefer the Copal #3 shutter because it can stop down further. Exact weight depends on whether it’s in an aluminum or brass barrel (and what type of shutter, if any). Symmetrical design but quite sharp at infinity when stopped down to typical shooting apertures. Single coated.
                على الرغم من وجود بعض الخيارات الجيدة عند 600 ملم، إلا أن كل خيار لا يزال به تنازلات كبيرة. الخيار الأكثر طبيعية هنا هو Fujinon C 600mm f/11.5، لكنني لست الوحيد الذي يعتقد ذلك - فقد أدت شعبية هذه العدسة إلى بعض الأسعار غير المعقولة، خاصة في السنوات الأخيرة.

                تعد عدسات Nikkor T مقاس 600 مم f/9 وSchneider APO Tele-Xenar مقاس 600 مم f/9 من العدسات المقربة التي لا تتطلب قدرًا كبيرًا من تمديد المنفاخ - وهي ميزة رائعة حقًا - ولكنهما عدستان ثقيلتان للغاية، ولا يحتوي Nikkor على مجال للحركات على 8×10. وفي الوقت نفسه، فإن وزن وسعر وندرة عدسة Schneider APO Tele-Xenar 600mm f/9 تجعل عملية بيعها صعبة للغاية.

                وهذا يترك عدسة Goerz Red Dot Artar 24″ f/11، وهي عدسة أسطوانية ذات طبقة واحدة، وإن كانت جيدة جدًا. (لدي الإصدار الأطول مقاس 30 بوصة للتنسيق الكبير جدًا وأجده حادًا جدًا.) أوصي بالبحث عن نسخة من العدسة التي تم تشكيلها آليًا في مصراع Copal #3 وتحتوي على محول خيط المرشح. يمكنك أن تدفع لميكانيكي مثل SK Grimes لتصنيعها بهذه الطريقة نيابةً عنك، لكن السعر لن يكون منخفضًا، خاصة وأنك ستحتاج إلى شراء Copal #3 منفصل.

                إذا كنت تريد شيئًا أسهل على محفظتك، فأنا أفكر بالفعل في الانتقال إلى عدسة Nikkor T مقاس 720 مم وبفتحة f/16 في القسم التالي.


                Even though there are some good options at 600mm, each one still has major compromises. The most natural choice here is the Fujinon C 600mm f/11.5, but I’m not the only one who thinks that – the popularity of this lens has led to some unreasonable prices, especially in recent years.

                The Nikkor T 600mm f/9 and Schneider APO Tele-Xenar 600mm f/9 are telephoto lenses which don’t require quite as much bellows extension – a really nice benefit – but they’re both very heavy lenses, and the Nikkor has no room for movements on 8×10. Meanwhile, the weight, price, and rarity of the Schneider APO Tele-Xenar 600mm f/9 make it a really tough sell.

                That leaves the Goerz Red Dot Artar 24″ f/11, a single-coated barrel lens, albeit a very good one. (I have the longer 30″ version for ultra-large format and find it to be quite sharp.) I recommend searching for a version of the lens that has been machined into a Copal #3 shutter and has a filter thread adapter. You could pay a mechanic like SK Grimes to machine it this way for you, but the price won’t be low, especially since you’d need to buy a separate Copal #3.

                If you want something easier on your wallet, I’d actually consider jumping to the Nikkor T 720mm f/16 lens in the next section.

                    هناك الكثير من الخيارات الرائعة من 240 مم إلى 270 مم. يمكنك أن تصبح خفيفًا جدًا مع العديد من هذه العدسات، أو الحصول على فتحة قصوى ساطعة مع بعض خيارات f/5.6. ما يلفت انتباهي حقًا هو Fujinon W 250mm f/6.7 - فهي خفيفة نسبيًا ولها فتحة قصوى رائعة تبلغ f/6.7، بينما توفر مساحة واسعة للحركات. إنها عدسة قديمة بعض الشيء وهي ذات طبقة واحدة وليست متعددة الطبقات، ولكن هذه مقايضة جيدة، خاصة بالنظر إلى السعر.

                    إن أبرز الميزات البصرية - الحديثة، والمتعددة الطبقات، وذات دائرة صورة كبيرة - هي Docter Germinar-W 240mm f/9 (على الرغم من صعوبة العثور عليها) وRodenstock APO Sironar-S (على الرغم من أنها كبيرة وثقيلة جدًا). تستحق عدسة Fujinon 240mm f/9 أيضًا الإشارة إلى سهولة حملها وبصرياتها، لكن ضع في اعتبارك أنها لا تقدم الكثير من الحركات.

                    بالمناسبة، عندما أذكر في الجدول أن العدسة مُحسّنة للتركيز البؤري القريب، فهذه سمة متأصلة في التصميمات المتماثلة أو شبه المتماثلة. وهذا لا يعني أن العدسة سيئة عند التصوير اللانهائي، وخاصة عند التوقف، يمكن أن تكون ممتازة عند التركيز على مسافة. ومع ذلك، مع هذه العدسات ذات التكبير 1:1، سيتم التخلص تمامًا من العديد من انحرافات العدسة.




                    There are lots of great choices at 240mm through 270mm. You can go ultralight with many of these lenses, or get a bright maximum aperture with some f/5.6 options. One that really catches my eye is the Fujinon W 250mm f/6.7 – it’s relatively light and has a nice maximum aperture of f/6.7, while offering extensive room for movements. It’s a bit of an older lens and is single-coated rather than multi-coated, but that’s a good tradeoff, especially considering the price.

                    The optical standouts – modern, multicoated, and with a large image circle – are the Docter Germinar-W 240mm f/9 (though it’s very hard to find) and the Rodenstock APO Sironar-S (though it’s pretty big and heavy). The Fujinon 240mm f/9 also deserves a mention for its portability and optics, but keep in mind that it doesn’t offer much in the way of movements.

                    By the way, when I mention in the table that a lens is optimized for close focus, that’s an inherent characteristic of symmetrical or near-symmetrical designs. It doesn’t mean the lens is bad at infinity, and especially upon stopping down, it can be excellent when focused at a distance. However, with such lenses at 1:1 magnification, many lens aberrations will be completely eliminated.

                        حوالي 300 مم، يمكنك العثور على عدد كبير من العدسات مقاس 8 × 10 التي من شأنها أن تلبي أي احتياجاتك. تعتبر عدسات سلسلة Rodenstock Sironar-S وSchneider APO-Symmar على نطاق واسع من أكثر العدسات كبيرة الحجم وضوحًا على الإطلاق، كما أن Nikkor W هو منافس قريب جدًا يتم بيعه مقابل جزء صغير من السعر. وفي الوقت نفسه، إذا كنت بحاجة إلى شيء أصغر، فإن Fujinon A 300mm f/9 أو Fujinon C 300mm f/8.5 هي خيارات رائعة. وفقًا للميزانية، سأحصل على Nikkor W إذا كنت لا تمانع في الوزن، أو Schneider G-Claron 305mm f/9 إذا كنت تفعل ذلك (ليست عدسة متعددة الطبقات، ولكنها حادة جدًا وبها مساحة كبيرة للحركات).

                        أحب استخدام عدسة G-Claron 305mm f/9 لالتقاط صور قريبة، وفي هذه المرحلة تعد واحدة من أفضل العدسات المصححة عند هذا البعد البؤري. تم تحسين معظم الكاميرات الأخرى (باستثناء Fujinon A 300mm f/9) للأهداف البعيدة، بشكل عام في أي مكان بدءًا من التكبير حوالي 1:10 إلى التركيز اللانهائي.

                        Around 300mm, you can find a ton of lenses for 8×10 that should meet any needs you have. The Rodenstock Sironar-S and Schneider APO-Symmar series lenses are widely considered some of the sharpest large format lenses ever made, and the Nikkor W is a very close competitor that sells for a fraction of the price. Meanwhile, if you need something smaller, the Fujinon A 300mm f/9 or Fujinon C 300mm f/8.5 are great choices. On a budget, I would get the Nikkor W if you don’t mind the weight, or the Schneider G-Claron 305mm f/9 if you do (not a multicoated lens, but pretty sharp and with tons of room for movements).

                        I like using my G-Claron 305mm f/9 for close-up photos, at which point it’s one of the best-corrected lenses at this focal length. Most of the others (apart from the Fujinon A 300mm f/9) are optimized for distant subjects, generally anywhere from about 1:10 magnification to infinity focus.

                            لديك العديد من العدسات للاختيار من بينها في نطاق الطول البؤري 355-360 مم لـ 8 × 10، لكنها جميعها غير ملائمة بعض الشيء. الخياران الوحيدان خفيفا الوزن هما Fujinon A 360mm f/10 وSchneider Tele-Xenar 350mm f/10 - كلتا العدستين الباهظتين، خاصة Fuji، ولا تتمتع عدسة Schneider حقًا بقدر الحركات التي أفضلها 8 × 10.

                            كما هو الحال مع 300 مم، تعتبر عدسات سلسلة Rodenstock APO Sironar-S وScheinder APO-Symmar هنا من أفضل العدسات ذات الأداء البصري على الإطلاق، وأسعار Schneider منخفضة جدًا هذه الأيام. لكن السؤال هو إذا كنت تريد حمل شيء ثقيل إلى هذا الحد.

                            إذا كنت تريد حلاً وسطًا جيدًا، فقد تكون عدسة Graphic Kowa 360mm f/9 هي أفضل رهان لك. إنها عدسة متناظرة ذات طبقة واحدة تزن أقل من معظم الخيارات الأخرى هنا. إنه ذو حجم خيط مرشح معقول وهو لطيف وحاد عند التوقف، على الرغم من أنه أقل قليلاً على النقيض من بعض الخيارات الأخرى.

                            ويجب أن أذكر أيضًا أن هناك العديد من العدسات الأقدم مقاس 355 مم (غالبًا ما يطلق عليها عدسات مقاس 14 بوصة) والتي قد تتمكن من العثور عليها في الغالق. يمكن أن تكون هذه خيارات رائعة، لكن معظمها يعاني من نفس المشكلات المتعلقة بالوزن المرتفع والسعر. هناك خياران بارزان هما Goerz Red Dot Artar مقاس 14 بوصة وKodak Commercial Ektar مقاس 14 بوصة، وكلاهما مشهوران بالتصوير الفوتوغرافي للصور الشخصية، على الرغم من أن Goerz لا يحتوي على مساحة كبيرة للحركات عند التركيز البؤري اللامتناهي.

                            لست متأكدًا من سبب احتواء النطاق 355-360 مم على مثل هذه الخيارات غير الملائمة للعدسات مقاس 8 × 10 مع الأخذ في الاعتبار أنها قريبة جدًا من البعد البؤري "العادي". ولكن في بعض الأحيان هذا هو ما يحدث في التصوير الفوتوغرافي ذو التنسيق الكبير. ربما يكون من الأفضل استخدام عدسة مقاس 300 مم و450 مم بدلاً من ذلك، إلا إذا كانت لديك ميزانية لشراء Fujinon A 360 مم f/10 أو لا تمانع في حمل شيء ثقيل جدًا.

                            Fujinon A 360 مم f/10 مع 8×10 Fuji Velvia 50




                            You have several lenses to choose from in the 355-360mm focal length range for 8×10, but they’re all a little awkward. The only two lightweight choices are the Fujinon A 360mm f/10 and the Schneider Tele-Xenar 350mm f/10 – both expensive lenses, especially the Fuji, and the Schneider doesn’t really have the amount of movements that I’d prefer on 8×10.

                            As with 300mm, the Rodenstock APO Sironar-S and Scheinder APO-Symmar series lenses here are considered some of the best optical performers ever made, and the prices of the Schneider are criminally low these days. But the question is if you want to carry something that heavy.

                            If you want a good compromise, the Graphic Kowa 360mm f/9 may be your best bet. It’s a single-coated, symmetrical lens that weighs less than most of the other choices here. It has a reasonable filter thread size and is nice and sharp when you stop down, though a little lower in contrast than some of the other options.

                            Also, I should mention that there are many older 355mm lenses (often termed 14” lenses) that you may be able to find in a shutter. These can be great choices, but most of them suffer from the same issues of high weight and price. Two notable options are the 14” Goerz Red Dot Artar and 14” Kodak Commercial Ektar, both of which are popular for portrait photography, although the Goerz doesn’t have much room for movements at infinity focus.

                            I’m not sure why the 355-360mm range has such awkward options for 8×10 lenses considering that it’s so close to the “normal” focal length. But sometimes that’s how large format photography goes. It’s probably best to stick with a 300mm and a 450mm lens instead, unless you have the budget for the Fujinon A 360mm f/10 or don’t mind carrying something quite heavy.

                                على الرغم من أن الخيارات تتضاءل في هذه المرحلة، إلا أن النطاق 420-480 ملم لا يزال لديه بعض الخيارات الجيدة لـ 8 × 10. إن Fujinon C 450mm f/12.5 وNikkor M 450mm f/9 هما جوهرتان مطلقتان. حتى أنني أشهد على استخدام Nikkor Q من خلال تجربتي الخاصة - فهي عرضة للتوهج قليلاً، وقد قمت مؤخرًا بالتبديل إلى M، لكن العدسة مقاس 450 مم Q لا تزال واحدة من أكثر العدسات حدة التي استخدمتها على الإطلاق.

                                أما بالنسبة للخيارات الأخرى، فلن أشتري العدسات الأثقل في هذه القائمة بغض النظر عن السعر. إن Fujinon 450mm f/12.5 وNikkor M 450mm f/9 جيدان جدًا بحيث لا يمكن الحصول على أي شيء آخر. وفي الوقت نفسه، تحظى بعض العدسات الأقدم مقاس 420 مم (أو العدسات مقاس 19 بوصة) بشعبية كبيرة في تصوير الأشخاص، بما في ذلك عدسة Fujinon L المذكورة أعلاه.

                                Although the options are slimming at this point, the 420-480mm range still has some good choices for 8×10. The Fujinon C 450mm f/12.5 and Nikkor M 450mm f/9 are two absolute gems. I’d even vouch for the Nikkor Q from my own experience – it’s a little prone to flare, and I did recently switch to the M, but the 450mm Q is still one of the sharpest lenses I’ve ever used.

                                As for other options, I wouldn’t buy the heavier lenses in this list regardless of price. The Fujinon 450mm f/12.5 and Nikkor M 450mm f/9 are just too good to get anything else. Meanwhile, some older 420mm lenses (or 19″ lenses) are popular for portraiture, including the Fujinon L lens listed above.
