Recently picked up a Sigma 12-24 to use for realty listing work. I have been using the 8-16mm Sigma on my 7D Mark II, but am in the process of selling off my crop gear while in anticipation of a shiny new 5D Mark IV that should be arriving Wednesday.
I have already sold off the 8-16mm Sigma, but one of the agents I work with called and had a job that couldn't wait. I slapped the 12-24mm on my 7D Mark II headed out the door.
Happy with the lens so far, had a pretty good flare when pointing pretty much straight towards the (out of frame) sun at 12mm. Seems acceptably sharp on the 7D and physically a bit larger than the 8-16mm. I had a chance to see the 12-24mm f4 Art in person at Kenmore camera over the weekend and that thing is massive.
I think this one will do just fine...
When you put the image on the TV, you couldn't find a shot of a sack of Tom Brady . . .?
