I do wish people when referring to corner coverage would be careful to elaborate. One can imagine illumination of the corner with minimal definition, suitable for OOF foreground and sky but not detail in focus, and illumination (or partial illumination, corrigible in post) with good definition.


Yes. And yes.

So, a better way to refer to this, and 'sides' and 'corners' in general, is to divide the general image circle into concentric rings - Zones A to D. These correspond to vertical stripes on MTF charts. For more on that, please see here: Fuji GFX Adapted Lenses

Also, discussions involving the GFX have revealed the need for a more precise definition of 'coverage'. Perhaps the clearest definition of coverage would involve the absence of a 'hard' (whatever that means) vignette caused by a mechanical obstruction. Where a soft vignette begins and ends is - literally - a grey area.

As has been pointed out, if we apply too strict a definition, many native lenses would not qualify as 'covering' their own format. A particularly heinous example of this is the Sony 18-135mm which at 18mm is completely inadequate for APS-C.

I think we have to regard illumination as the fundamental, but aberration as a distinct, secondary property. White wall tests effectively show whether a lens 'covers' GFX, but it doesn't quantify deleterious aberrations in Zone D. It's also true (noted earlier) that vignetting inconsistently differs with focal length and aperture.

To give an example: wide open, it appears that both the Sigma 50mm Art and Tamron SP 45mm cover GFX with only a soft vignette. The Sigma throws a better illuminated image circle at f1.4 than the Tamron does at f1.8. However, only when stopping both down and observing their different behaviour in Zone D do we see that the Tamron reaches a peak of performance at f8-f11 in which aberrations are largely absent. Whereas stepping through the full range of apertures with the Sigma Art, it is shown in extremis that its image circle is actually smaller, inasmuch as its Zone D is never aberration-free.

As an amateur photo enthusiast, I have been struggling in getting better cameras and lenses within budget for many years. Fortunately to me, this money-burning and time-consuming practice has somehow satisfied my exploring curiosity as a technical man and improved my photography skills. I believe many people in this forum have the same situation like me.

Like many others, at the beginning, I tried to adapt different types of 3rd party lenses to GFX since I got a second-handed 50s last year. Recently I switched to a new 100S, I of course will continue to do so. My practice involved 35mm

A fellow traveller! Welcome . . .

The only reason I have a GFX is to give an optimal outlet to my collection of enlarger, projector and industrial lenses. I'm gradually compiling vignette maps at the page linked above: they may be of interest to you - Fuji GFX Adapted Lenses.

It seems that if we put our heads together we could greatly enlarge the range of lenses covered. I'll PM you.

Recently I made a close comparison of the Schneider Apo-Componon 60/4 with the Nikon EL-Nikkor 63/2.8 and found the Nikon even better suited to general use, and fully covered GFX. But there are hundreds of these lenses that work brilliantly on the GFX. See also Delta Lenses

Maybe by first converting to M mount a 'la Funleader Kit or similar? I would have to think they would suffer from heavy vignetting and/or corner smearing on the larger sensor however.

Helios time! Of both the Helios 40-2 and 44-2 I appreciate the center sharpness - and the unsharp / bokeh areas even more.

Great vignette map test! nikon rayfact industrial linescan or its enlarger version 63/2.8 is an ideal prime lens for 4433 system. For 28mm legancy 35mm fullframe lens, the MD 28/2.8 is also very good.

Hi, what adapter are you using to mount the El-Nikkor 63mm f2.8N enlarger lens?

I gather it is M39 mount. I have found two mounting options:

One that is almost flush with the camera - Fotodiox sell this https://fotodioxpro.com/products/l39-gfx-p

And one that appears to act as a focusing helicoid - found this on AliExpress https://fr.aliexpress.com/i/33050051836.html?gatewayAdapt=glo2fra

This leads me to wonder about the Nikkor lens itself - does it have both aperture and focus rings?

Sorry for the links, I wanted to post photos of the adapters but I'm too new on the forum I think.

Interesting stuff. I have both the El-Nikkor N 50mm 2.8 and the 80mm 5.6. They both have M39 thread. No focus mechanism, so using these lenses on a GFX requires a helicoid adapter.

Thanks for that Aliexpress link. Browsing on Aliexpress it looks like there are various sizes helicoid adapters, to allow for infinity focus at various focal lengths. I will order the adapter for 80mm, assuming that the 50mm will focus beyond infinity on that adapter but that's ok for now.

Yeah random find but it seems these are made by Pixco and designed for specific lenses, ie. Rodenstock 80mm and 90mm f4 and Industar 75mm and 110mm f4 lenses.

https://pixco.com.cn/search?type=product&options%5Bprefix%5D=last&q=M39+gfx

I have emailed them to ask if they will make one for the El-Nikkor 63mm f2.8N! 🙏

Not sure if you're aware of this amazing resource:
