Fun read.

Roger, a little more to digest... ; - )

I'm struggling trying to understand what this article is purporting to represent other than comparing numbers. Newer autofocus motors are given a nod without mentioning that third party support for...

On my Z7, I have the Record button (next to the shutter release) set to Magnify, with peaking on (always). I don't shoot video. Peaking is only useful with some lenses and depends on aperture... I ...

There are some pertinent threads over at Fred Miranda such as this (newer lenses): https://www.fredmiranda.com/forum/topic/1512530?b=2 and this (older lenses): https://www.fredmiranda.com/forum/top ...

Somewhere out there is an article or two about Nikon's sensor design group and their interest in creating sensors that complement lens designs. I would suspect Canon does the same as they both ...

The Z7 offers a wide range of in-camera image processing options for raw, jpg & tif. Combinations of Image Quality, Image Size and Image Area settings can reduce file sizes while retaining high ...

It's a good point. The usual post processed examples provided on this site leave a lot to be desired. For instance, if one was looking at noise, and just at the RAW examples, one would assume that ...

A relatively inexpensive route might be to try some of the legacy 20mm Nikkors... http://www.mir.com.my/rb/photography/companies/nikon/nikkoresources/ultrawides/20mm.htm I have both the UD and f/4 ...

Worth a smile... "The usual method of correcting it is to loosen the retaining rings, bang the lens on a table a few times, and tighten it back up. That probably sounds ridiculously crude, but it...

I have gone (one example) R to 4/3 to m4/3 to E to Z (four adapters)... R to M to Z is a bit more direct though... ; - )

Roger, thank you for reiterating the usage approach to testing lenses that you have often mentioned in your blog. For your test shots, do you generally take raw, jpg or both?

If the M rangefinder is optimized for 2-3m, it kinda makes sense that the typical lenses designed for photo-journalistic usage would be also...  Now you understand the value of infinity (and mfd) ...

Some of the other F mount options... http://www.mir.com.my/rb/photography/companies/nikon/nikkoresources/ultrawides/20mm.htm

I did a double-take on the 0.5mm... I thoughtlessly just assumed an across-the-board  0.7m. So I checked most of mine and wide(r) lenses seem to be 0.5m, normals usually 0.7m and (short) teles ...

This is what one gets with field curvature... The effect varies with the particular lens, the point of focus, aperture and distance to background. Some lenses have a wavy field curvature where the ...
