First of all I'm a fast shooter, I move a lot and I shoot in all conditions. I've been photographing for 8 years.
The AF on my model isn't good for anything other than direct sunlight and it slows down, often still being slightly out of focus. I manually focus 90% of the time but there are times when I simply want to point and click(warranty ran out a month before AF got buggered)
I'd like a AF beam which even the NEX series has instead of using the flash strobe.
I want better colour reproduction, the photos I've seen straight out of the camera from other manufacturers is amazing instead of me having to tweak colours to appear right in post production.
I want to downsize more than anything, something small and efficient, a interchangable lens Sony RX1 made by Canon would be my ideal camera."I guess I'm ready for an upgrade and I want to stick to Canon due to my lenses yet"With that MUCH lenses, I highly recommend you to switch NOW.
I have a Canon 550D with a Sigma 17-70 F2.8-5.6 and Canon 50mm F1.4
Honestly, I'd be happy with a improved Canon SL1/EOS M with adapter. I don't like bulk since I shoot on the run a lot and don't need many of the features that the higher end models have.
As an owner of RX1, color straight out from camera is flat. I'm talking about JPEG.
If you want better AF, there is 5D III + 1D X.
You mentioned you own Sigma 17-70 F2.8-5.6 and Canon 50mm F1.4, by just having 2 of these lenses why not switch to another brands to full fill your needs. Why wait for 7D II? What do you know about 7D II? Would you buy 7D II if the price tag @ 3000plus?
The only things I know about the 7D II are the rumours that have been posted here. I don't want a 5D or 1D due to size and features I don't need, I mentioned that in my original post.
I will switch to another brand if the announcements don't meet my expectations.
