I am contemplating the purchase of Tamron SP 85mm f/1.8 Di VC USD for use on Nikon Z7 and D800e.
But, as I also have 645z, I am also curious, what is the closest equivalent for such lens for 645z.
I could not yet find any comparisons of that lens to medium format, so I'd appreciate any input. Thank you!

Same image diagonal: 108mm f/2.3

Thank you Jim. Looks like there is nothing quite similar for 645z. Tamron it is then:) With 1.8 the eye AF on Z7 should be quite handy.

So why not choose nikon own 85 mm 1.8 s ?
From my own experience and testsites it is a marvel.

Pentax 645 120mm f/4 macro? Yes, not as wide - an f/2 would be ideal, but it doesn't exist. The 120mm macro is a pretty amazingly sharp lens, plus it's vintage, so cheap relative to new lenses.

I do have 120 F4 and 150 2.8 for 645z and both are excellent lenses.
For Nikon, I wanted to get the F mount, so I could use it on Z7 and D800e. Had I only had Z7, 85mm S would be the absolute top choice. The only issue I see with that lens is cat's eye bokeh towards the corners (which likely was a compromise for containing the lens size and weight, that is consistently maintained in the Z system).

Zeiss 135/2 APO covers the sensor (same as Fuji, X1D, etc) and is well regarded on the GFX. The Zeiss 100/2 Macro might, but is infamous for colour fringing.
