I'm using a EF-S 10-18mm f/4.5-5.6 IS STM and love it... well, in good light. Problem is that I am shooting with a 7D2, and when filming wedding receptions, f/4.5 really is hard to deal with.
I think I may need something faster; but want to have something ultra wide still. I owned the 16-35L II; but I am really wanting something 10/12mm at least. I had the 20mm 2.8 as well. Just not wide enough for my 7D2.
Any recommendations on something that may work better for me in low light? and will still give me nice quality?
Thanks!
