Ive been a lucky boy, as ive borrow this lens for the weekend for a couple of football matches and my god its incredible! Nothing like ive used before!

Its paired with my 40D so nothing amazing there, but iam now very very jealous of the owner :lol::lol::lol:

Anyway iam going to be using it again on Tuesday for a nighttime flood lit game, how do you think it will cope? I think it might be much better actually as the light on Sat was awful KO was 14:00 this morning was alot better KO 10:30.

Another quick point is the 1.8 6.5 switch. Iam always zooming in and out, I assume 1.8 is for the closer stuff and 6.5 further away?
 
minimum focusing distance on this lens is around 6ft (1.8m) but you can tell it to ignore everything closer than 6.5m away, useful if your shooting through fences or have something in the foreground such a hedge line etc that AF could be distracted by. As for the lens coping under the floodlights, hard to say, I don’t think its great in low light but maybe that’s just me. The 40D is not great at handling higher ISO either ( I speak from experience) so not too sure if you will maintain a high enough shutter speed to get sharp shots of football action, pretty sure you will get something from the night though :)
 
Thanks Rick, will just give it my best. ISO 1000 max?
 
I would say anything beyond 800 ISO on the 40D will be too noisy, possibly even too noisy at 800 TBH.
 
I'd say that a noisy but sharp photo is better than one that's blurred but has less noise so use the ISO setting you need to get the shutter speed required.

If they're generally being sized downwards later on anyway then you can get away with more noise.
 
Is it best to stick the lens in IS mode 1?
 
So exited, getting to use this lens again on Saturday :D :D :D
 
It's a brilliant lens for sport, but the f/5.6 at full stretch is a bit of a problem. As Stuart says, a noisy shot is better than a blurred one, so bang up the ISO until you can get a decent shutter speed - an absolute minimum is going to be around 1/250 and even at that you'll get some blur. Do you have any noise reduction software? You may be better with IS turned off. This only steadies the lens and does nothing to slow down a fast-moving subject, but try both.

Yeah I can defo bump up the ISO now ive jumped from the 40 to the 7D :D

I do, LR 4 ah ok will try without IS then cheers. Yeah its a pain at 400, or it might even be at 300 it drops to f5.6 :( oh well!
 
I would love to say I would try ETTR but in reality it will probably be too much for to manage, but thanks for the advice. Something to try in the future I think. Just trying to get everything in the frame atm, and framed right well and exposed correctly!
 
IMO, unless you insist on pixel peeping or making big crops, the 40D is absolutely fine at 1600 ISO. This is at 1600 ISO, shot raw and unedited....

The light was bad enough that I could only muster 1/125 at f/5.6 and 1600 ISO.

Here's a 100% crop before and after some small tweaks to reduce noise....

For shooting sports, where the shutter speed should be kept high and the movement is random I would advise turning IS off altogether. If you're trying to track action and have IS turned on then it will be fighting your own efforts to move the lens. You don't want that.
 
I tend to switch IS off at around 1/1000th as it doesn't seem to help any, if anything I find it a bit of a hindrance and seems to add an element of blurrr. This lens also doesn't seem to like the filter I have, a kenko pro1 digital uv filter, seems to make the autofocus hunt somewhat I have found out today, images also seem to be a tad sharper too without it!
 
Just got the lens now but it's doesn't want to focus on my 7D :(
 
Probably a silly question but you have got af/mf button in right setting?

Well it's firing ok in MF, but not in AF. Lens works fine with my 400d
 
When you say 'won't focus' do you mean nothing happens at all when you try, or it won't lock? Have you tried both distance settings? Turned IS on and off? Cleaned the contacts on both lens and camera?
 
Does anyone have any experience with the custom settings using the 7D and 100-400? Iam shooting a football game tomorrow.
 
Have you managed to get it to focus during the six months since your last question?
