Great review. But I wonder what is better? The Mamiya 120mm Macro or the Pentax 645 Macro lens. This may be asking too much, but can you do a review of the Mamiya 645 35mm wide-angle lens for the GFX system? Thanks!
Seems your updates are missing a big deal from the pics. The A version shows a manual aperture adjustment. The others are missing this and may be a problem adapted? This nearing the weight you can load a gfx body when extended?
As a new convert to the 100s... this was a fab insight. Subscribed, and looking forward to more deep dives into vintage glass. PS. I did just buy an 18mm macro ring for go with the native 45-100mm zoom. A great pairing. But I loved the colours from you snaps... beautes!
Hello, Thanks for the video. I bought a version of this lens (the A) to use with Fuji GFX 50R for scanning negatives. I have a Fotodiox adapter. The f-stop ring moves, but I am not seeing the diaphragm/aperture change. I moved the switch from A to M and still no movement of the diaphragm. Am I doing something wrong? Or is this lens damaged? I do have the 80mm macro and that seems to work fine on my setup. I thought this would be the same. Thanks.
A good test to see whether a lens can outresolve the GFX sensor is to put the aperature at f/5.6, take a photo, then do a pixel-shift multishot under the same conditions. If the pixel shift image has more detail than the regular photo then you know the lens is capable of outresolving the GFX sensor. The aperature is important here because beyond F/7.1 you will be diffraction limited and pixel shift does not help. Then if the lens is too wide open you will have to deal with abberation induced blur which could cause blur limited performance. Again, pixel shift will not help. F/5.6 seems like the general sweet spot where many lenses are sharpest. You also know the performance will not be diffraction limited, because that limit is f/7.1.
Very big difference! 645 almost always better as far as sharpness and sensor coverage. Only downside is that most 645 lenses are slower / smaller maximum aperture. I think the fastest 645 lens is f/1.9 (Mamiya 80mm).. Most are f/2.8 and slower.
I don't think it was fair to compare the weight and size of the GF120mm with a Mamiya 120mm - the Mamiya offers 1x while the GF120mm would require at least the (very expensive) 45mm extension tube, increasing the bulk and weight and even then the image quality would be far below the Mamiya.
This is a great channel. Please keep the content coming.
Will do, thanks for taking the time to watch and comment! :)

Try Minolta MD 75-150mm f4. Lovely to use!
thanks for this.. really well done videos .. love the level details on the info.
Very welcome, thanks for watching and taking a moment to leave a comment! Definitely more coming!

Thanks so much, glad it was helpful! :)
great review! wondering how would compare to the Contax 645 Makro Planar 120mm

Are you surprised / in doubt this lens resolves the 100 sensor?
How is the difference between a 135 lens and a 645 lens?

Mamiya 150mm f/ 2.8 and 210mm f/4 it is better...
Good video but please... once it's established you are talking about a "lens", you don't need to say it every sentence... it hurts my ear holes.
