why only a prime? why not consider a zoom?

Fast zooms are still f2.8.

I agree with others, 85mm f1.8 is the best bet for money.

Or rent 200mm f2 IS for a day.:)

I don't know about kids, but for adults in typical gym lighting you need more than f/2.8. Not to mention, a sharp/fast-focusing zoom costs a lot more than the 85mm f/1.8. And at the end of the day it's still a stop slower. If you have the $$ a good mid-range zoom is certainly more versatile overall, and is probably fast enough for kids. BUT the prime is deadly sharp and you'd get the shot at ISO800 instead of 1600 etc..

Also - not allowed inside the lines to take a photo...of a kid's TKD class? Wow they're a little too strict IMO. I can't believe they wouldn't let you so long as you don't make a habit out of it.

They only go to the large gym during testing for a new belt and also for exhibitions.

So, no shooting inside the line, since it will distract the kids during testing.

I`m close to getting the Canon 100mm f2 , but I got spoiled by the Sigma creamy blur background that gives better isolation of the subject... Need help :-(

You'll get creamy blur on the 85 or 100 on your 5D, don't worry :-)

If your using a 5D FF, I would go for the 100mm. I think 85 would be too short on a FF from where your standing.

The gym looks like your typical public HS or Jr HS gym. Lighting is not usually real good, either. You have two realistic choices:

1) the 85mm f/1.8. Shoot at 2.0, 1/500-640 to stop motion blur and raise ISO until proper exposure can be achieved. You'll also do a lot of cropping based on the shooting position in your example. Cost: ~$320-350 used.

2) 135mm f/2.0 L. Same settings, more reach, prettier pics, less cropping necessary. Cost: ~$950 used.

Agree with others that in general, and from my experience, f/2.8 lenses don't produce really good results in HS gyms without supplemental lighting. If you can shoot at ISO 6400, then my experience goes out the window and a 2.8 WOULD work. From what I'm seeing, you need a longer lens that can be opened to f/2.0 or better.

85mm is great but I prefer the 24-70mm for the zoom factor if needed.

I personally tried to shoot at f2.8 inside a school gym (probably similar lighting), and it was NOT enough to get a sufficient shutter. I always found myself at 1/100 under ISO 800, 1/160 sometimes I could pull off, at f2.8. nevertheless all my pictures just sucked- underexposed, blurry, etc.

the 85 1.8 or 135 f2 is your way to go.

+1, or you could get a 30D and the 85 1.8 and get more apparent reach yet

Believed or not but I have shot Judo with my 50mm 1.8 (ASA 800 at 1/1000sec). Considering how erratic that camera auto-focus is I got over 650 to 700 shots right on target (I always use center point auto-focus). However, I am saving money to get either the Sigma 50mm 1.4 or the Canon 50mm 1.4. I think you should check both lenses reviews. In addition, my understanding is that the 85 1.8 is a fantastic lens.
Good luck with your decision.

only choice IMO:cool:

85 will be too wide on FF

I've used the 85 1.8 on a crop camera and it worked, but it depends on how tight you want to frame it.

If I would do it again I would use a 70-200 2.8 and crank up the iso if you need more shutter speed. I have a few shots on my flickr with the 85 if you want to check them out.

I shoot my kids Taekwondo all the time. In a gym from the stands I used my 135L, but from the floor I use my 24-70 with the 580EX. The difference is staggering. Without a flash my shots just look flat. I don't even bother anymore unless I can get on the floor with my 580.
But I'm sure many here do just fine with that crap lighting, shooting RAW with a custom WB, I've just never been happy with that.

I believe you, but that is unusually awesome indoor lighting. More commonly it's maybe 1/500 at ISO1600 at f/1.8

Flash is great, more light is better. But they might not let you use it.

Never had a problem, but it doesn't hurt to ask I guess:)

Didn`t see anyone used a flash there. I think 100mm f2 is perfect for my FF body on this situation.

Will this lens give a nice blur background isolation than the 85 1.8 ? I heard 85 has more CA problem.
