This is another test that I shot a paper.

Where can this lens be purchased in the US?
Thanks,
Dan

I bought it on a Chinese second-market website. The price is around 1,200USD. I had saw another used on eBay few month before.

Updated 2x test result

Thanks Chris and Lou, I will try some experiments to find the problem and the solution.

Seems I'm not using the lens to full potential on my lowly APS-C sensor! But maybe someday I'll graduate to FF, and it will still be useful.

What surprised me the most was its control of colour aberrations at the edge. If you use shift-shift shooting, this increases the range of movement.

great images, and it seems that it's diffraction limited even on the small pixel pitch of the GFX100. not sure why the overall contrast gets so much lower when stopping down though, any ideas? I think one of the reasons may be related to the electronic shutter. I used an LED board as the light sour...

First I would like to thanks dmillard who gave me the adviser on https://www.photomacrography.net/forum/viewtopic.php?t=41029 This lens covers GFX sensor perfectly. It makes me easy to shoot film between 0.5-1x. (Update 2x test on 12 Aug) Camera: GFX100 1x test I crop 5 position of 3 different apert...

The Printing Nikkor 105 A is a very impressive lens. However, you may be interested in nathanm's 1x test on his PhaseOne sensor (67mm diagonal) in which he showed that a Schneider MacroVaron had better performance at the image edges. https://www.photomacrography.net/forum/viewtopic.php?t=33627&high...

So that's a 44x33mm sensor? Nice to hear there are no medium format edge effects due to micro-lenses or other digital sensor complications. However, your posted coin example doesn't really show that very well, since there is no detail in the corners or even on the far edges. May I suggest that a pe...
