I'd say it would have to be over $1k. Here's hoping that they will redo the 50mm 1.4 into an Art lens and maybe come out with some standard f/1.8 zoom for FF.
Sigma needs to redo the whole line-up. For a start the 20/24/28 f/1.8 need to be entirely redone and use HSM, much better coatings and their new FLD glass. They need to add a OS to the 500, 800 and 300-800 and preferably make an f/4 model of the 500. They should bring back the excellent 400 f/5.6 APO, with OS, and HSM. They need to do a sports series high quality 500mm zoom and who cares if it doubles in price if they get the IQ way up. A 125-500 f/4-5.6 OS HSM that is fully optimised for the long end, unlike their current offerings. Maybe they could look at 400 f/4 or 200-400 f/4 as well. Next they need a FF UWA zoom, possibly a 14-28 f/2.8 or even a 16-40 f/4 OS.
