After watching the poll on the lens table for many years, I can't help from commenting on the results. I'm totally stunned that the Canon 10-22mm is the most popular lens, and it has been for the entire three or four years I've had a lens poll. Not that it isn't a great lens, it may well be the highest quality lens for cropped sensor DSLRs. I'm surprised that it has always beat the Sigma 10-20mm. The Canon 10-22mm used to be over twice the price of the Sigma 10-20mm back in 2011 when I first did a post on this subject. Nowadays, the Canon 10-22mm is only about $100 USD more than the Sigma, what a deal!
I think it is awesome that PFRE blog readers are into quality. This preference for quality also shows up in the long time popularity of the 5DMkII. I wouldn't have predicted this. I would have predicted that the cropped sensor Canon DSLRs would be the most popular DSLR. This poll shows that a large percentage of real estate photographers are using fullframe DSLRs. Very interesting! This result tracks my preference, I've been using a full frame DLSR since the Canon 1Ds came out in 2003. Some people have pointed out the contradiction that if the 5DMkII is the most popular body then a fullframe lens should be the most popular. More than likely not everyone that takes the lens poll also takes the DSLR poll so they don't track perfectly.
