Brilliant! I blame my stomach to head size ratio on foreshortening...

Check out DXO ViewPoint. It has volume distortion correction in it to help with this. If you post an uncropped version I can run this on it to show you what it can do.

Thank you, Shawn.
But I can correct these sorts of distortions with tools I already have if I wanted to "correct" things. That's not the point of what I do in my photography—or particularly with this kind of camera/lens setup—so I don't use any of those tools.

I have my own SWC, but being an awkward sod I want to do the reverse and crop my Cambo Wide 65mm to square and use it like an SWC on steroids. I came to the conclusion I could adapt the Hassie finder to my cambo and just get on with it, your calculator suggests the angle of view is just right if I've worked it out correctly. You've also got me using my 15mm voigtlander ver III on my M240 and evf with square crop marks and black and white settings, already looking like fun, but actually not as much fun as my SWC........

Excellent thread. There’s something special about wide and square.

Did you add the crop marks to the EVF? I didn't think the M240 had an option to do that but I may have missed that as I rarely use the EVF.
Thanks,

Nice, I didn't realize there was any other software that had corrections for volume distortions.

M240 latest firmware includes cropping options, just click pad around info button up or down, shows crop marks in live view, on back or in evf

Once upon a time, I wrote the software to do volumetric corrections on images myself... I wrote such stuff when I worked for NASA/JPL in the 1980s.

The CL has no framing options that include a square crop, but it's not hard to estimate it by displaying the grid overlay in the viewfinder. Having the grid on also helps keep your verticals/horizontals oriented square properly, pretty important when using such an ultrawide lens...

Another cafe stop... I was sitting outside. These two young men arrived and took the table next to me. Their behaviors were so disparate in the ten-twenty minutes I was sitting there having lunch and watching them it was almost enough to make me laugh.
Leica CL + Voigtländer 10mm f/5.6
ISO 400 @ f/8 @ 1/50
A few others of their friends arrived a few moments before I departed, and I noted that their behaviors normalized. I nodded to them, just kind of saying goodbye, as I left. The one on the left barely noticed, the one on the right gave me a smile and a little hand gesture to say, 'thanks, see ya.'
Ah, communications in the modern age...

Nice photos, Shawn.
Do you have anything further to say about the lens?

Still getting used to how wide it is. In the corners it will show some purple CA in high contrast situations, it vignettes and has a little bit of barrel distortion. The Lightroom profile corrects this easily, see below. It is well behaved on the Sony and Leica. I haven't really seen any color shifts on the sides and it doesn't smear on the Sony like some wide angles do. Good lens that is pretty compact for what it is.
Uncorrected on A7RII @f8
With LR lens profile for the lens applied (at default, might be overcorrecting the vignetting at this aperture so down to 80% or so looks better)...

Sounds good!
The corners and edges look to have improved quite a lot over the older VC 15mm f/4.5 v1 that I had, a good thing for sure. Very nice to see that.
And yes: It does take some time to get one's head into these extreme wide angle views. I had some documentary work to do for a warranty claim yesterday and fitted the R60 macro lens ... I felt like I'd just put on an ultra-telephoto after shooting with the 10mm for three weeks.

These were taken with my M240 and Voigtlander 15mm ver iii. This lens is crisp to the corners at all apertures from wide open on M240, Sony A7s and Nikon Z6. I also have the 15mm Ver ii which I use on my Minolta CLE, it is crisp all over at any aperture on tri-x, but soft on the borders on all my digital cameras and italian flags on the Leica and nikon. Usable stopped down on the Leica in Black and white, but now I have the ver iii I don't bother as the ver iii is fabulous on digital.

Out for my bicycle ride on Tuesday, doing a slightly different take on my loop at a different point in the day than usual, I came through the edge of the University, rounded the bend, and my eyes were blinded by the glowing red umbrellas at the local pizza parlor. I had to stop and photograph it, and then I had to figure out how to make the photo look like what blasted my retinas ...
