HI ALL

A friend of mine wants me to help him shoot a Squash game - Here is a link to some Squash photos - And I do not think that I have the proper lens to get the event; I tried with my Canon 15-85mm, and all the shots were in the range of 15-25 mm this is on my 60D canon which is not a full frame camera, so that make it about 10 to 15 mm for a full frame camera if I do get one in the future.

The problem is that the Canon (15-85) mm is not fast enough for the occasion, and I had to go to ISO 2000 to get the photos at the not so greatly light court.

So I need a lens that ranges from 10mm to about +-30mm being Canon or else and has an f-stop less than 2.0 and will mount on my 60D and a full frame Canon if I ever make the improvement step.

ANY HELP PLEASE.

First of all, if most of your shots were taken at 15-25mm on your 60D, this is the equivalent of 24-40mm on a full-frame camera. Canon makes a 24mm f/1.4 and a 35mm f/1.4 in that range.

Thanks you are right.

15 mm on the 60D is 24 mm on a full frame yes yes . So I need a lens that is between 15-30 mm and works in full frame cameras and the 60D

What would that be?

I see you have a 16-35 mm but it's 2.8 and I need two stops down from the 3.5 I have.

As far as I know they do not make a zoom lens faster than f2.8 so that leaves you with primes. wide fast primes

Sigma do a 20mm f1.8 and 24 and 28
Canon do a 24 f1.4 and a 35 f1.4

hope you have a lot of spare cash as these are expensive

If I do not get word that there's a wide zoom lens that is less than f=2 I think I will get the Sigma.

Thanks very much

Because of the very, very high cost for a good, fast lens; I would not recommend going out and buying one just for one shoot unless you have money burning a hole in your pocket.

I recommend you check to see if any local camera stores will rent you a top quality fast lens and try it out on that shoot. Then you can chose to buy it later if it proves acceptable.

I found this personal review of the Sigma 20mm f/1.8 you are considering that might make you reconsider it as a choice:

Btw... your picture of a blue lizard reminds me of a fun hour I spent chasing around a blue lizard in the Sonora Desert to get close enough for this picture:

Love that game... Miss not playing (too old now and my heart would explode :-) and not that common in the US - I don't count racket ball).

I think your answer has to be a combo... That sig 20mm looks great but I don't know how fast it will focus which will be important unless your pre focusing. I don't know of a lens the speed your talking of that can be FF and crop and zoom.

Your also probably just going to have to push iso faster then 2000..... I don't know the 60D but doesn't it have the same stuff inside as the 7D - if so then with some post 3200 is most likely good enough but after that it gets ugly (I find the 7D noisy anyway).

Personal reviews are just that, personal. One opinion of one person is not much too go by. If you want to use personal opinions, look here, it holds 66 opinions for this lens, and they very a lot.

As with any Sigma lens, individual copies differ in quality, and so will user reviews. If you find a good copy, it is a good lens for the price. I have a good copy myself and used it with great pleasure (until I switched to the Tokina 11-16, which is wider and has more corner sharpness).

I think your personal review is most revealing when you said that you "used it with great pleasure (until I switched to the Tokina 11-16, which is wider and has more corner sharpness)".

For other input... how about this review:
In-depth review by Photozone

Or this one:
In-depth review by Cameratown

Or this one:
Review from The-Digital-Picture.com

Or how about actual comparative photos found in this review:
Tischler's comparison images

Together this input from numerous sources should give anyone a good idea how good/bad the lens is.
