28mm f/1.8, 35mm f/1.4, 50mm f/1.4

I am ready to pick up a new lens and was wondering if anyone can give some advice.

Which of the three would be a good choice to use when I go to aquariums, I know all would be but I can't afford all three.

My 17-40 is not cutting it, thanks.

35 1.4 would have a field of view that you are most used to along with the 28 1.8. The 35 is the best lens in the bunch, but then you pay for that quality. If you like the focal lengths you get from the 17-40, i'd say go with the 35 out of the bunch.

It's a tough choice between the three. I have the 28 f/1.8 and swear by it. It's my most used lens. The 35 f/1.4 is better, but as Grego said, you pay for it. I also have the 50 f/1.4, but I'd think that would be a bit long for shooting in an aquarium.

thanks guys for the advise. I am sort of leaning towards a 35 f/1.4 with a week to decide.

If you can afford the 35, get it. It's close to "normal" on a cropped camera (I may be falsely assuming that's what you use), super fast, and sharp. The 50 is frustratingly long indoors, IMHO. The 28 is supposed to be a sweet lens but if you can afford the 35L you get a speed (1.4 vs 1.8) advantage.
