Let me make it as plain as possible. It's all related to why Ibis is important for these small lightweight cameras. I've used an M1 professionally for 5 years, in many situations. So mirrorless is not new to me.
Anyways, here's my points in a simple fleshed out list.
1- I have several month old M50. The body itself is nice and functions well. Good shape, and controls.
2- THAT BEING SAID, the plastic feels cheap and it feels very fragile.
3- I'm encountering trivial shooting situations where Im getting oof images of the subject. A model in front of the camera, not moving for example. This is the main problem.
4- It's well documented that with higher density sensors, you will likely have to double your shutter speed (say, compared to 18/20mp sensors of old) to get sharp photos as he sensors are more sensitive to slight movements.
5- No one talks about the shutter shock with these cameras, so I bring it up so that it can go on fellow camera buyers radar. Combined with the above characteristics, AND no Ibis, it's basically a recipe for many blurry images. That is exactly what I'm experiencing..right now.
6 - The added weight of adapting heavier EF lenses hasn't helped, which I find strange. The EF 35IS is usually attached to it, however the blurry images persist.
7 - Many mirror less cameras use electronic first curtain shutters that can eliminate the affects of hardware shutter shock. However, this body doesn't have that function in manual.modes. Thanks Canon
6- So that's the situation I'm in now. I love the body. But the combination of being very lightweight and all of the above make it very challenging to consistently get well focused images. And that's a HUGE problem, obviously. I do want to keep it but if I cant find a way to resolve this critical issue, it will have to go.
That's all I've been trying to say here. I'm just sharing my experience, take it as you will.
