Fast USM Lens that will give me 35mm FOV on 1.6X

(1/3) > >>

Currently I have a 14mm f/2.8, and I have a Tamron 28-75mm f/2.8. My camera body is a 7D, and I think I am not taking full advantage of it (focusing). The Tamron is obviously the lens I use the most, and I have not really had a problem with focus hunt on my 7D in low light, but it is somewhat slow focusing. I am looking for a fast f<2.8 lens for my 7D that will give me a full frame equiv FOV of a 35mm lens. It seems my options are slim in this field.

24mm f/2.8--> Too slow, and too slow to focus no USM
24mm f/1.4L---> Too expensive
28mm f/1.8 USM ---> Would be perfect if only it was 4-6mm shorter
20mm f/2.8 USM-----> To slow

Is there any third party that makes a lens that fits my specific needs?

I might just dump this idea, and just purchase a 100mm f/2 USM now, and save up for a 24mm f/1.4L II in a few months.

I have the 28 1.8 on my T2i, which has a similar sensor (if different AF), and I LOVE this lens. Like you say, it's bigger than you want, but I use it quite a lot. Great build and IQ.

There's not really an alternative to the 24L. There's a Sigma 1.8, but I don't know how good it is and it also doesn't have an ultrasonic motor.

I really hope Sigma will bring out a 24mm f/1.4 at some point.

I could really use the rumoured Sigma 24mm f/1.4.

Can I ask what you are intending to use this lens for, because most people don't use wide angle lenses to track fast moving subjects.

The Tamron lens you have is slow to focus, but that doesn't mean that all non USM type lenses will be as slow, so you should at least try them out first,  As for the 100mm f/2  most of us have a 100mm F/2.8 macro & would then choose the 85mm f1.8 which gives an extra half stop while only losing 15mm
