The 6D is a repackaged 5D2, which is a repackaged 20D w/ a FF sensor.
Save your dough and buy a used 5D2+glass or a 5D3.
I keep seeing this same post by RLPhoto
in response to the 6D over and over. I consider RLPhoto a solid and talented photographer who consistently offers great advice here, no offense is intended by my comment but... his response to the 6D is out of character for him because it indicates an assumption opinion apparently based on specs that isn't backed up by first hand experience. And the repeated posting of it seems to indicate a desire to prevent others from making a mistake in purchasing the 6D.
I've shot about 4000+ images so far with the 6D I've owned for about a month. I also own the 5D3, 60D, 40D, 30D and original 5D. I've shot the 5D2 as well. The 5D3 and 6D are the first NIB bodies I've purchased. I normally purchase most of my equipment used. I agree that the current Canon prices are ridiculous. I purchased the 6D because I find the 5D3 low light performance and AF to be lacking. In another month or two I will likely sell either the 5D3 or the 6D. If Canon somehow magically fixes the 5D3 AF I would be inclined to possibly keep it but as things stand now, unless I do a lot of sports shooting (which I don't), the 6D will easily win this decision.
I can assure you that IMHO (based on actual use) the 6D is not a repackaged 5D2, 20D or whatever is being assumed
. The 6D IQ is comparable to the 5D3 IQ and the 6D is superior to all other cameras in low light. The 6D simply works great as an entry level (or even mid level) FF camera. Everything I have read from actual 6D hands-on use and reviews is positive. My knee-jerk reaction to the 6D spec sheet several months ago was also negative. But I gave it a chance and I'm glad I did.
