The 'All Canon EF-M lenses' club

That's quite a collection you have there! I have a mere 7 EF-M mount lenses (Canon 22, 32, 11-22, 18-55, 18-150, Sigma 16, 56). Actually, it's 6 now, because I have just sent off my 18-55, along with a bunch of other lenses and converters, to mpb for sale. I got the 18-55 with the original M in a kit on firesale for around $400, and that included the 22 pancake, a little flash and a mount adapter! When I bought the M6 in a kit with the 18-150 and EVF, I just didn't use the 18-55 anymore. I found the quality about the same through the shared portion of the range, so the only advantage the 18-55 had over the 18-150 was size. But the 18-150 isn't that big, and the extra range is really useful. I mostly use the 18-150 when I'm traveling, and want a do everything lens. My most used EF-M lenses are the 22 and the Sigma 56. I often carry my M6II with 22 mounted in a little bag that also has the 56. I find the M6II and 56 to be a superb portrait combination. The 22 is just a really fun lens to carry around on the M6II (or M6, which I still have) as a stealth carry-everywhere combination. I get great results from it too, especially when processed with DXO PL5. The best EF-M lens I have, and almost certainly the best one ever made, is the 32 F1.4. It's simply superb. I don't use it as much as the 22 and 56, though, because I slightly prefer the 35 (FF equivalent) and 90 focal lengths to the 50. When I do use it, I'm always amazed at the quality. I would put it a tiny bit ahead of the SIgma 56 in optical quality. The other lens I use a lot is the 11-22 for landscapes and cityscapes. Great sharpness in a tiny lens. I know that a lot of R7 and R10 users are hoping for an RF version of that lens. My least used lens is the Sigma 16 F1.4. That's mostly because it's also my biggest EF-M mount lens, and, for me, the M is all about portability. It does give great results, though, and can be very useful indoors. And, to be fair, it's only big in comparison to other EF-M lenses.
