Hi Snigs

Nice shot and impressive hands (with the IS)

Thanks Chen - the canon IS + sony IBIS is really useful.

I have noticed you use Sony body with Canon lens.

Yes, I don't have any native lenses, so cannot really compare.

1. How it the compatibility with the adaptors? I understand AF is working but slower.

Most of the modern lenses work with PDAF once I upgraded to software version 3.1 for the Sony. The AF is really quick and comparable/better than my Canon Rebel body (400D). The Fotodiox adapter is fine, but often I have seen that the adapter refuses to focus and either I manually help by bringing the focus near enough and then the adapter works, or reset the camera body. I think people have better experience with Metabones or Sigma adapter, but there is no option to update the software in Fotodiox.

The adapter does not AF with my Tamron 28-75/2.8 lens and that is a bummer. It is one of the sharpest 2.8 lenses that I have used (for the weight). Also it does not work with 50 1.8 II, 24 f/2.8 and 35 f/2 (older lenses).

The adapter does add a bit of bulk, but I find that it works fine with prime lenses (and fails with large 2.8 zooms as the camera + lens combination feels uncomfortable).

There is an odd flare that happens with this adapter (and most of this kind) when there is a light source just outside the frame - most likely internal reflections from the adapter - you can flock it yourself, or get the Metabones T adapters.

The adapter does not work at all for video and it hunts forever. But I don't shoot much video to begin with, so not much experience with that.

And you have to keep IS on and IBIS on for 5-axis stabilization. And there is no Eye-AF or DMF, or magnification for AF lenses in AF mode. . For that you need the big bucks for either native lenses, or Metabones adapters ... And I think that the USM makes more noise with the adapter than on a native Canon body.

2. How is the transition to EVF instead of OVF? Is it that good? How's the operating time of the camera, that you have live view in the viewfinder?

This is phenomenal experience once you adapt to the EVF. It is nice, clear and bright, and sharp. Manual focusing in bright sunlight with older lenses is a breeze. If you use Loxia or other E-mount compatible manual lenses, it auto-enlarges on focus change. The peaking is not very accurate for fast lenses, but it is quick to magnify and then you can accurately focus. I have used it quite successfully with canon FD lenses, and I still use this with FD 135 f/3.5 lens

I have not noticed any particular lag in low light, but I tend to take my time (to the chagrin of my wife and daughter). Under very low light, the EVF is grainy, but AF works well enough to not worry in many cases. I don't think I will buy another camera that does not have a built in EVF. I am sold on the convenience, and the electronic level built into the EVF.

Thx for the input,

You are most welcome - regards Snigs
