Quick review based on my ratings and why. 5 is an I don’t care, 1 is really negative, 10 is really positive.
Overall Rating 6.5. I like it more than I don’t like it, but that’s because of ML(Magic Lantern). I used it a lot at first, but now it only really comes out when I want to use fast MF lenses. For me, if I want to go small and out, I’d rather grab the Fuji x20 than the M+22mm.
Overall Image Quality 6.5. No surprises here. I will give a better score in my t2i review, when I first saw images from an 18mp aps-c sensor!
Value for Money 8.5. Got it during one of the US fire sale. This category is where the M, at least from those who picked it up at discount, should do the best.
Must Have 5.5. By itself, it is kinda blah. It can make some nice pictures, but overall, its a lot harder than it should be. It is cool that you can put all your EF/S lenses on it, but the only photographer that I would say the M is a “must have” is one who really likes manual lenses. Focus peaking with ML and f/1.2 glass is so much easier than through a viewfinder and the M maximizes cost/sensor area/IQ.
Suitability to Intended Use 5.5. It is suitable for my use, but I do not use it as Canon had intended.
Got what I Expected 6.5. I knew about the AF before getting it, just did not think it would be that not so good.
AF Performance 2.5. Mine came with the firmware improved AF. Its not horriible, but coming from some of the better AF systems, this one takes a while to get used to. When it works, great, but sometimes, it just hunts in scenarios which I would not consider that bad. It hunts enough that I can actually hear the sound in my head as I type this, and I haven’t touched the camera in months.
Handling and Ergonomics 7.5. I got small Asian hands. A lot of the hand holdable electronics from Asia seem to fit my hand size quite well.
User-interface 6.5. Its all touch screen driven. For AF that works out nicely, but for changing settings regularly, it can be a pain.
I originally got this with the 22mm, on the cheap, as a “pocketable” 35mm equivalent walk around. I had no intent in buying anything else other than some cheap 3rd party adapters. I ended up at least trying the EOS adapter, the ef-m 11-22mm, and the ef-m 18-55mm. After all that, I have the most fun using it in live view focus peaking with fast manual lenses and seeing how thin the DOF really is.
