Primes for my 7D:

[Kusca]

So I sold my A700, and switched systems I purchased a Canon 7D, I also had a Tamron 28-75mm f/2.8. It is a sharp lens, but I love prime shooting. On my A700 my 35mm f/1.8 SAM was 95% of the shots I took (if I had a wide angle lens that would drop to 65%). I am getting rid of the Tamron 28-75mm, and instead purchasing primes. I am 100% on the following lenses:

Samyang 14mm f/2.8
Canon 85mm f/1.8

However I cannot choose something for in between those lenses, I bought a 7D for fast focusing so I would like something with USM, I cannot choose between these lenses.

28mm f/2.8
50mm f/1.8
I can get those together or:

28mm f/1.8
Because of budget constraints I cannot get both the 28mm f/1.8 and the 50mm f/1.8
35mm f/2
50mm f/1.8
Or finally the

24mm f/2.8

I would like to get something as close as possible to 35mm FOV on a full frame for my 7D, and sharp, fast and fast focusing would be great.

Thanks for the help TPH!
