Fuji 56mm f1.2 Full Frame?

Fujinon 56mm f1.2 - Adapted to Sony A7ii & A7r

Fuji 56mm f1.2 on Sony A7r



Forget Fuji vs Sony, time to Combine the power of Fuji and Sony 🔥


Salah satu lensa favorit saya di sistem Fuji, selain 16mm f1.4 adalah 56mm f1.2 yang saya yakin juga jadi lensa idola banyak fuji user.
Nah salah satu pertanyaan yang saya sudah lama pendam, adalah seberapa bagus sih ketajaman lensa Fuji? 🤔
Yang dicintai para Fuji mania kalau menurut pengamatan saya adalah sensor Xtrans dan hasil Jpeg serta simulasi filmnya, alias color science Fuji yang memang sebaik Canon (Jpeg doang ya...)
Karena itu saya ingin mencoba lensa Fuji ini di sistem kamera lain, untuk cek apakah memang lensanya termasuk performa ok seperti Olympus dan Panasonic lens.

One of my favorite lens on Fuji system is the 16mm f1.4, the other one is the 'venerable' Fujinon 56mm f1.2 which I'm sure is on a lot of people bucket list.
Now, one of the fact I've been curious about is how sharp are Fuji Lenses.
As you may know, Fuji is famous for their Xtrans CMOS, and the Jpeg / film simulation, or Fuji's color science, which is equally loved as Canon's.
That's why I've been hankering to put this lens to test, is it worth their premium, such as Olympus / Panasonic or just plain overpriced.

Masalahnya berbeda dengan sistem kamera DSLR yang gampang dipasangkan di mirrorless, lensa mirrorless biasanya tidak bisa dengan mudah diadaptasi ke sistem body lain, kecuali dengan cara oprek / modifikasi mount nya
Kebetulan teman saya om Ayat adalah salah satu jenius dalam oprek lensa, dan saat saya lihat lensa satu ini, tidak pakai lama langsung inbox buat beli  😍


Saya beli lensa ini tanpa tahu apakah bakal bisa dipakai di full frame atau tidak
Tapi saya sempat baca artikel ini dari tahun 2015 lalu, kalau memang diameter mount Fuji dan Sony tidak jauh beda. Yang saya khawatirkan tinggal performa lensanya, apakah bakal vignet parah seperti lensa APSc lain di full frame.

The problem with adapting mirrorless lens as opposed to DSLR lenses is that the flange back distance is already all very narrow, so adapting it with an adapter would be impossible.
The only way to do it is with modification on the mount, which is no easy feat.
As it happens, one of my friend is a very skilled lens technician, he did a great job modifying this lens to fit my Sony A7r


I bought this lens not knowing if it gonna work on Sony's Full Frame camera.
That being said, I already read a nice article from John here, which stated that the mount size isn't that different. So what I'm most worried about is the lens performance, weather it will vignette much or not.



Perbandingan ukuran Fuji dan Sony mount
Untungnya ternyata lensanya bisa mengcover sensor full frame secara sempurna. Tidak ada vignete dan hasilnya cukup baik. Setara dengan lensa-lensa manual / jadul seperti Canon FD 58mm f1.2 dan Nikkor 50 / 55mm f1.2

Lucky for me, it turns out to work pretty well, the lens covered the full frame sensor nicely, and the performance is on par with the popular classic lens, such as Canon FD 58mm f1.2 and Nikkor 50mm f1.2

Dengan modifikasi ini, kontrol focus dan aperture tidak melalui body kamera lagi. Lensa Fujinon walau ada aperture ring di lensa, tapi tidak berfungsi mekanik, hanya elektronik saja, jadi mirip tombol saja sebetulnya, tapi bentuknya ring.
Fujinon yang versi for Sony ini tidak ada aperture click, jadi pergantian aperturenya non klik, cocok untuk videografer

With this modification, the focus and aperture control is no longer by body / electronic. Originally the Fujinon lens had an aperture ring, but that doesn't work mechanically, it's just sending electronic signal to make the body change the aperture.
This sony modified lens have clickless aperture, suitable for videographer.

Straight out of Camera result Sony A7r :




Straight out of Camera result (Sony A7ii)


Hasil ini sebetulnya tidak bisa dibandingkan langsung karena lokasi foto berbeda, dan saya tidak bisa mendapatkan file raw dari A7ii (pinjaman)
Tapi dari pengalaman sebelumnya, memang saya lebih cocok dengan hasil lensa-lensa manual dengan A7r karena tidak adanya AA filter, jadi hasilnya relatif lebih tajam
Di sisi lain, A7ii memiliki keunggulan di sistem yang lebih baru dan cepat, serta adanya IBIS

Kesimpulan dari beberapa kali foto, lensa 56mm ini cukup tajam. Tidak kalah dengan legacy lens populer seperti nikon, minolta, canon fd 50mm f1.2.
Prestasi yang tidak main-main untuk bisa menyamai lensa lensa klasik tersebut, apalagi untuk lensa dengan fitur AF seperti fujinon 56mm f1.2 ini



This result can't be directly compared since the photo is in different location, and I didn't get my hands on the A7ii raw files (loaned)
From my previous experience with manual lenses on Sony FF bodies, I prefer the A7r result much better since it omits AA filter, thus making the image taken sharper.
Do remember that with A7ii you'll get a newer system and also built in IBIS.


My take on this lens is that it's very sharp for its class. Can rival the legacy lenses. 50mm g1.2 from Canon, Nikon and Minolta have similar performance, and that's no easy feat for any modern lens, especially one with AF
