It's getting to be that time of the year. I've talked to several people that expect the man with the long white beard to bring them a new DSLR so I thought is would be interesting to take a look at what the top selling DSLRs are.
This data is based on Amazon sales so yea, it doesn't include B&H sales and other retailers but since Amazon is the biggest online retailer on the planet it's a pretty good bet that this ranking is pretty good characterization of overall sales. Here are the top 10 selling DSLRs:
When I started out putting this post together I didn't expect to find four full frame bodies on the top ten selling DSLR list. I guess it makes sense since we are now to a point in history where there are both first and second generation full frame bodies available and you can even get a full frame body for under $2,000 (5DMkII for $1,699). Also note that you can now pick up a used 5DMKii bodies several hundred dollars less than new ones on Amazon.
I think all of these are a good choice for real estate photography and the full frame bodies (#6, 8, 9 & 10) are the best choice if it's in your, budget. It's worth noting that according to the poll on the PFRE Camera Page the 5DMKII is used by more PFRE readers than any other camera body. That is, it's the most popular real estate camera.
A reminder: if you are going to upgrade from a DX (cropped sensor) body to a full frame body you may need to upgrade your wide-angle glass too. Lenses like the Canon 10-22mm and Sigma 10-20mm are not designed to work on full frame bodies. The PFRE lenses page lists the lenses that work on full frame bodies (see the bottom two sections).
