As a Minolta 7D shooter, I have invested thousands of dollars (camera bodies, lenses, misc. equipment, etc.) into their A-mount. Now that they are bought out by Sony, I have to decide whether I should stick with their new offering - the Sony A700 - or sell my stuff and jump to a different camera brand.
One of my biggest pet peeves about the Minolta 7D was the (excuse my language) shitty autofocus speed. Their older film SLR cameras had a faster AF speed - simply inexcusable!
Popular Photography recently ran camera tests on the Canon 40D and Sony A700. I still await their test on the Nikon D300 - which might be *the* camera that dethrones Canon.
In the interim, the two reviewed cameras seem very similar. PopPhoto finds that...
- Canon and Sony's AF speeds are very similar except in dim-lit situations. Sony's AF starts to stink, thereafter.
- Canon edges out Sony in the noise department. It seems that Canon's smaller 10mp CMOS sensor (vs. Sony's 12mp) and experience with CMOS technology (and their handle on noise) edges out the Sony in this department.
- PopPhoto reports that the Canon has better color accuracy than the A700.
- A700's ergonomics are better than that of Canon's - a subjective debate.
I am, by no means, a "pixel peeper" (meaning I do not magnify and analyze every single detail in a picture).
Frankly, all of the cameras appear to be very usable. Plus, the Canon 40D and Nikon D300 bodies cost a few hundred more - on top of the cost associated with switching systems. Money is still an issue for me and most other non-professional hobbyists.
I foresee my current 7D being demoted to secondary (or even retired) status by either Christmas 2007 or early 2008.
