I don't know about anyone else, but I've been waiting for 2 years for Canon just to release these two products. In my mind it's an absolute no brainer for Canon.
5D Mark III
- 32 Megapixels
I know lots of people who have either FF or APS-C cameras, and never needed more than 8MP after cropping. People who need to crop more than 100% of the pixel regularily are either the exception or novice photographers.
I do know plenty of people who want cleaner images, more DR, higher ISO, higher FPS, and smaller images to improve performance (less processing time, less disk space, etc).
It's certainly not a no brainer - there are plenty of people who would prefer less MP. Of course there are people who do need more, but there's no reason their needs would decide what everybody else should have.
- no more low iso noise problems
- 7D Autofocus
- Improved Dynamic Range
- Lower noise (signal to noise ratio not just noise reduction)
That I'll sign with both hands and a foot.
I had a 24-70mm F/2.8, and I sold it. My priorities for buying a new one would be
1. Size. I don't deny the benefits of all pro lenses having 77mm filters, but if that what it takes, I would share 67mm filters with the 24-105mm f/4, or use step-up rings.
2. Performance wide open, especially corners at the wide end (24mm-35mm) and field curvature.
3. Image stabilizer, as I should hand held in evening light and shows. As it's a wide lens, this is not my top priority, and would be happy with 2 stops.
