Barney, for the next trade show would you be so kind and take a little styrofoam brick wall with you, so you can set it up at any distance for your test shots and properly satisfy the focus-plane-brick-wall-professionals here. 😉
Seriously now, I thought that this lens delivered some very nice shots of you, especially for being such a fairly wide WA, with very good looking bokeh. The ceiling and its corners, o well, I don’t care so much about ceilings (or brick walls).
Speaking of bokeh, a shootout for WAs as well as other FLs would be a really nice thing, including one for portrait lenses like Nikon’s two 85s.
Thanks for your preliminary report and the sample pictures, much appreciated!

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
