Why not canon eos m?
probably is strange that not canon ,but I want to try something different than canon this time.I still keep my old Canon 450d ,and I have compact canon s120 /which I had to send to repair twice/, and I had canon 70d for a while / great video recording/ but much too heavy.
So just probably need some change, why not Olympus then?
Here is what DPR had to say about the EOS M3, and the lack of native lenses for it. I really haven't kept up with this camera; the lack of lenses was a turn off for me when the first one was announced. Thus, if you disagree with the following, don't shoot me: I'm only the messenger.
(DPR impressions follows)
"While feature access has changed in dramatic style, the lens range hasn't – and everyone knows that enthusiasts look at a camera's lens range before the camera itself. I am certain there are plenty of photographers who bought a Fujifilm X-T1 because they wanted to use the XF 56mm f/1.2, or those who invested in a Micro Four Thirds body to be able to use the Leica DG Nocticron 42.5mm f/1.2. Canon's EF-M range really doesn't have anything to compare with these fine optics and the hypnotic draw they constitute for enthusiast photographers.
We have had it drummed into us since 1987 that the EOS system is about optical quality. In more recent years Canon's digital EOS range has been about the combination of that optical quality, Canon's homemade CMOS sensors, and the speed and accuracy of the system's autofocus. By contrast, autofocus in the M was shockingly poor.
Canon representatives cross their fingers behind their back when they explain that every desirable focal range is covered in the EOS M range, with zooms that take us from 11mm to 200mm (18-320mm in 35mm terms). Anything else, they go on to make clear, can be hooked in from the EF-S and EF ranges on the end of the EF-EOS M adapter. It is easy to read in their eyes that they too wish they had nice fast primes to talk about, zooms with a usable aperture range and that they didn't have to suggest mounting massive lenses to a tiny body that is supposed to be part of a tiny system.
But Canon has only four EF-M lenses in its range - one is a standard kit zoom that compares with every other standard kit zoom in the world, and two are zoom lenses with maximum apertures that start at f/4 and f/4.5. The only lens that anyone might conceivably think interesting enough to pay any attention to at all is the EF-M 22mm f/2 STM. And that magic gateway to the EF range, the EF-EOS M adapter, is not very easy to come by at all.
Canon's pitch that the EOS M3 is aimed at the enthusiast photographer only makes the EF-M lens range look even more inadequate. Which retailer will stock an enthusiast camera that has no lenses to sell with it, and which enthusiast will buy a camera body without looking to see what lenses will support it? If Canon does want to make the EOS M system a success it should have introduced appropriate lenses with the M3, and if that wasn't possible to have used the resources it devoted to the camera to producing the lenses instead.
If Canon does have lenses on the way it needs to get them out fast, or the body will be considered old by the time they arrive."
