Lenses for the gfx 50s

[TonyVentourisPhotography]

It will be very interesting to see how well the 17 and 24m TS-E lenses work.  Too bad there isnt a 35mm.  I don't know if the Schneider 28 or older 35mm PC lenses would hold up well enough compared to just using a tech cam.

Otus 85 on this sounds very very exciting.

[Craig Magee]

The Canon 24 ts-e and the 1.4x TC work well as a 35mm. Not had any problems when I've used that combo. Maybe a little more CA.

Judging by the examples on the Alps site, the TS-e's will cover the sensor easily and should perform well.

Excited to look at the Fuji as soon as I can.

What will be the effective focal length conversion factor when using a 35mm full frame lens on the GFX?

Interesting, thanks for the link!

Cheers,

The new Nikon 19mm tilt shift is a potential candidate for a really wide solution of the GFX as well as the Canon 17mm already mentioned but like Canon, it would need an adapter with full electronic aperture control since it is an E lens.

What will be the effective focal length conversion factor when using a 35mm full frame lens on the GFX?

sqrt(24^2+36^2) = 43.27
sqrt(33^2+44^2) = 55
55/43.27 = 1.273
35mm/1.273 = 27.49mm

Jim, thank you.

Or roughly 0.8x

Or roughly 0.8x

Right. That's assuming you are going to use both sensors uncropped.

If you're going to crop to 4:3 or squarer, the crop factor is 24/33 or 0.727.

If you're going to crop to 3:2 or narrower, the crop factor is 36/44 or 0.818.

Which encapsulates what a leap it is from 35mm to the "new" medium format 

[ErikKaffehr]

Yes,

But for Fuji users it is a big step from APS-C to 44x33 mm…

Erik,
I think this is a really good point. From Fuji's perspective (and from a Fuji user's perspective), offering a 135 format makes little sense: Barely better than their APS-C offering and lots of tough competition. Especially if you remove the legacy mindset of 135 SLR being the standard. Fuji users love the layout and haptics of the system so it makes some sense to think of this as an upgrade for current Fuji users.

You can look at this two ways: 1) Fuji formats are almost as good as 135 and 54x40. Or 2) Fuji formats are a bit better than m4/3 and 135. Since the size of Fuji's cameras and lenses compare pretty well with #2, their strategy makes sense to me.

Assuming we will get a Canon EF - Fuji G adapter, 135mm lenses with sufficient image circle would be suitable for the Fuji GFX.
I tested quite a few 135mm lenses on my FPS IQ180. I cropped the test pics of the lenses with sufficient image circle to 44x33mm format to show some of the future options with that cool 44x33mm cam.

Canon EF 11-24f4
pics at f11
slight vignetting due to the sun shade
I assume no vignetting w/o sun shade

I don't have proper test pics to show corner sharpness but I think it's usable because others use that lens already w/ shift on the Sony A7Rii w/ 36x24mm sensor.

Excellent work! By any chance could you also test the Sigma 14mm f/1.8? Thanks

My main system is m43. The Fuji's "expansion factor" of ~0.4x is a leap you can believe in.

Does anyone know if the Fotodiox Nikon adapter will work with the G lenses, that don't have the aperture ring?  From looking at the adapter it seems to have a series of oooooooo markings on the front below an arrow, so not sure if this is a click less aperture arrangement or not.

BTW, I don't believe the Sigma Art 14mm 1.8 is shipping yet, at least in the US.  Wondering how it will handle coma.

Thanks

The description says that it will: "Fotodiox Pro Lens Mount Adapter, Nikon Nikkor F Mount G-Type D/SLR Lens to Fujifilm G-Mount GFX Mirrorless Digital Camera Systems (such as GFX 50S and more) ".

However, it almost certainly won't work with E lenses.

E lenses are likely to work at their mac aperture.

But I have a PC.
