It would be interesting to see the J-3+ and these other Sonnars used on a full-frame mirrorless. Sonnar formula lenses sit closer to the image plane than their Planar counterparts. The microlens array that Kodak used for their CCD's amazes me
Any A7 version with the Kolari thin filter mod is right in there with M240 and M9. I like the v2 Kolari, which is .8mm, as opposed to the stock sony 1.9mm cover glass. That mod costs 400 or 500 depending on the A7 version and is well supported by Kolari.
Here's the 28 cron on the v1 Kolari:

What about a Sonnar? Here's the Nikkor S 50/1.4 WO, now on an unmodified A7r:

So, for your samples a stock A7r2 would shoot the sonnars great because the FC induced by the thicker cover would not matter. There is nothing at the edges except the grass and it would still show sharpness, but closer compared to the center. It's the landscapes that gives everyone, including me, fits with the Sonys unmodified. Wide open shots seldom demand flat sharp edges---10%? Most everybody puts the subject in the center and fires away LOL.
But with the thin filter mod you get the lens at near film flatness, like the M9. Here is the Sonnetar around 1.5 on the A7.mod:

Film is flatter yet than the M9, as I'm sure you are aware, Brian. There are a number of small wides which are much better on film than a M9, like the CV 21 and that slow zeiss 21. But the bottom line is a used A7 is 700+400 for thin filter mod and for 1100 you have a very strong M shooter which can use any lens the M9 likes to good advantage: right out to the edges.
I still prefer my M9, and they are down to 2200, but the Sony mod makes a superb companion, because it not only does M well, but shoots my 500/4 P Nikkor like a dream
Anyway I love your sets with the sonnars, Brian, and it's very interesting to see the wartime Sonnar basically win the contest. At f/4 I think the J3+ is right with it, but wide open, my eye says the wartime sonnar wins in these samples. It's also so interesting to see how warm the other sonnars shoot.
Thank you so much for the report
