I agree with this statement



look at all the data, don't over look metering?
 
not really unexpected unless you're shooting in really bright conditions .. say you're at the long end, normally the max aperture is f5.6, but with a 2x on there you're losing 2 stops .. really best to use a 2x if you have a f2.8 to start

Does that even autofocus?
I once tried a 1.4x converter on my Sigma 120-400 which is also f4.5-5.6 and that wouldn't autofocus

If youre shooting at 400mm this will be @ f/11 surely which is fine for landscape but not sports, the AF will be seriously rubbish as well, so rubbish it wont work and you will need to use MF :D
 
Thanks all, with abit of practice i found that it wont autofocus at 400mm, f5.6, so usless for my needs, thanks again for all your replies.
 
You'll be able to do it when you get your 1DIII

I have a thread on here somewhere with a 1DIII 100-400mm and a 2x
 
I'm talking *******s, it was a sigma 1.4x

the tread is here

I was getting mixed up with the 300mm f2.8 and two 2x entenders stacked together making 1200mm (I think) :bonk:
 
You'd be better off getting a 300 f2.8 and using the converter on that to get the range while keeping AF
 
The MKIII is good but i dont think it will be a massive increase in IQ compared to your 5D MKII, personally i would opt to buy better glass ie a 300mm f/2.8 or even 300mm f/4 and stick a 1.4x or a 2x on it

The slower frame rate will hamper you but it will actually make you a better photographer as you will need to learn when to fire the shutter and pre empt where the action will be
 
300 2.8 is a big muther though, I found it quite poor for hand holding and the shots with TC werent very good, possibly due to camera shake or the lens being a bit knocked about (old press hack lump).
I'd rent a 300 2.8 before I bought one so as to be sure it works OK.
I'm looking at a 400 5.6 as its supposed to be light and great optics.
It will be mounted on either my 5D or 1D.

The 300mm 2.8 is fantastic with a 1.4 on it a little slower focusing but it is f/4 so expected. It is huge and a fair weight for hand holding I know I wouldn't like to do it for an extended period, a 6 hour streach shooting cricket with it on a mono pod is hard enough.
 
WOW..what a set of photos, unfortunitly my funds wont stretch to a f2.8 but they might go as far as a 300mm f4 + 2x extender which would mean i'd be shooting at f8 on the 1D mkiii but it will retain autofocus, on a good day and with a fair wind behind me would i have a fair chance with this combination for sports photos?
 
I am after a 70-200 mkII and the only way I can see is selling my 300 at the risk of upsetiing somoene from bolton :(

I am reading such good reviews about the 70-200 am thinking it can do the 300 job at stanley night matches sat in right place.. hmmm WANT ONE!

Always thinking.. always looking to wheel and deal :)

Same here, especially with the Jessop's interest free deal sitting on the table:
Min deposit circa £400 and then £140 pcm x 10.

My other problem is the new Sigma 120-300 OS. I know that the Canon 300 (non IS) should be the correct choice, but the reviews are looking soooooo good! :D

I have both and I'm not so sure it'll replace the 300mm but if the budget is tight it would certainly come up with the goods with a 1.4X.

I'll try a test next week and post the results. (it's hissing down here today)

Well I ahve the 400mm f2.8 as well so distance is covered.. I dont envisage a need between 200 and 400 that either the tc cant do or a good crop on a decent lens camera combo

its just that the 300 would be hard to part wiht.. very hard..
 
But what about those long shots in poor light when you cant get the shutter speed for the 400mm. ;)

Everything I see with the 70-200 mk2 makes me want one and I got a duffer shot the yesterday missed focus and over exposed at cricket and the halo/fringing of the cricket whites was terrible with my mk1 but that is the only time I have noticed anything I would like it to improve on.

So do I! I've got the 1D body, the extender, but not the 300 f:/2.8.
I've seen the results from this combo... Can't afford one.
I'm gonna go and sulk now :shake:

1d MK IV and 70-200 f/2.8 IS MK II is a superb combination. I'm getting some cracking action shots at dog agility.
