Welcome Philip - beautiful images!
Robert - I have the 1.4x magnifier and while it can help, I found it was much more useful to get a diopter correction eyepiece, if needed (which I did need). When the RF is properly calibrated, the double image 'pops' to form a clear one at the correct focus point, which is more noticeable if you have good eyesight, or use the correct eyepiece. For those with more complex eyesight correction requirements, there have been good reports about the Walter RX eyepiece, but I haven't yet tried this myself.
The problem I have with the 1.4x is that I end up spending more time fussing over focus. And because I tend to change lenses a lot, it's a hassle to go through the stages of removing the correction eyepiece from the camera, attaching the 1.4x magnifier, attaching the correction eyepiece to it, then reversing the process. In this respect, the EVF and live view capability of the M240, even if somewhat primitive compared to current live view cameras, does a much better job.
Therefore, my suggestion, based on my experience and discussions we've had here, is to find the right correction eyepiece and practice shooting with the 90, a lot. I also focus bracket slightly, when in doubt.
Adam, that's interesting about the 75AA vs. 90. While I haven't been a huge fan of 75mm just because I found it so similar to 50, I could see myself using it for weddings instead of a 50 and 90 because I tend to work relatively close to the subjects anyway. For many weddings I rarely shoot longer than 85mm. But for this, I'd probably want the 75 Lux. My statement about finding the 90AA relatively easy to focus was for a centrally placed subject. I've noticed that when wide open at near minimum distance, that focus & recompose can be a bit off with it, and that the lens may not be that great off center. Seems to be less of a problem at farther distances.
As for onion rings... I can provoke them from the 50 Lux ASPH too. It has to be a bright, distant pinpoint light source. Perhaps worth noting that the 85L is also an 'ASPH' lens. Looking at the Leica and Canon block diagrams for each lens, it looks like the aspherical element is similarly positioned. And Canon state it's a ground and polished one in this lens, rather than the more commonly found moulded type.
Maybe some day I'll compare it at f/2 against the 90, but offhand, the 90 appears better corrected against 'oof fringing' which I can see in the full rez in the 85L image above around the black text on the card. The 90 seems to do it too, but very, very slightly.
Here are some more 90AA test shots…

I like ALL your 90APO shots!
I'm going to try and provoke onion ring bokeh with my lenses when I have a bit more time. And I'll look through some older photos to see if I can find it.
As for the 75APO, I think it's almost a necessity for weddings, I just find it hard to pair it with any 35mm lenses that Leica offers. So when images are together in a series, it makes it hard to enhance the images to make them look the same. Maybe 75APO / 28Cron is a good match? Leica seems to think so on there site, but I'm not sure if they had rendering/drawing style in mind when they made reference to them being the perfect two lens kit.
I've also noticed that going back to my Canon setup, the 85 is now just a slight bit to tight for me.. hahaha I've been brainwashed by Leica it seems.

I disassembled it to fix a loose focus ring and a very (almost seized) aperture ring. It is all back together and works as new. Pretty funny how the smallest aperture is f/12.5.
