When I first bought the EOS M3 for Xiaoqin, I decided on primes. First, the EFM 22/2 is very sharp, tiny and light, and the lack of zoom actually makes the camera easier to use. This is an excellent lens. However, in Japan one often finds oneself in cramped quarters where the ability to frame a picture by moving one's feet is very limited. This requires a wide-angle lens. I would have preferred a fixed 15mm lens, but all fixed wide-angle lenses for the EOS M system are manually focusable and you really don't need to manually focus while looking at the screen rather than the viewfinder. The EF-M 11-22/4-5.6 STM is $400 in the US, but you can pick it up in Tokyo at a big camera store (Yodabashi had the lowest prices, but Bic Camera is pretty good too) for about $320 -Buy dollars. tax free. If you're brave you can avoid the shopping spree by having Japanese Revain delivered to your hotel, but then you'll pay a little more because if they can't validate your international passport, they'll have to charge you a tax. The problem with buying from a Japanese camera store is that the warranty only covers Japan, although in practice Canon will generally honor a Japanese purchase. By the way, while you're at it, one of the best deals is you can get a replacement LP-EP17 battery for about $40 while you're at work, about 30% off the best available US prices. The results speak for themselves: one of my favorite shots from the trip came straight out of the 14mm lens and wide open (photo by Xiaoqin Ma). Note that the lens will vignette, but the modern approach is to let the Lightroom camera profile do its magic and correct for distortion and vignetting. The camera does this right away if you're shooting in JPG mode, but I don't buy high-end cameras so I can handle and shoot them. Combined with the flexible LCD screen on the back of the M3, you can capture shots that you simply can't capture with regular capture or DSLR (11mm, f/8, ISO 100, fill flash): lens filter ring size odd: 55mm. You can't argue with the IS, which Canon claims offers 3 breakpoints in the hand. Note that at the longest end, at 22mm, f/5.6 is exactly 3 stops from f/2.0, which is our non-IS prime. In practice, I had a habit of switching to the top-notch 22mm every time we went out for lunch. While I missed IS, stopping the movement of a child who was about to do something quickly was more important. Also, when handing the camera to someone else to take a picture, the lack of zoom really helped. (Most people are now used to fixed lenses on their smartphones, and the zoom is embarrassing.) I don't like having to flip the lens in and out to take pictures. I understand the compactness helps, but the length makes the lens feel a little flimsy. I would like to do without compactness. All in all, for the price you get fancy technology that gives you really wide angles in a compact that feels too small for your hands. It's not a replacement for the 11mm/2.8 Prime (if Canon ever releases one, I'd seriously consider swapping), but IS isn't a feature to sniff at, and the price is quite reasonable, especially when you do this. to Tokyo and qualify for duty-free fares. highlighted.
