Sigma 500mm F/4.5 EX DG HSM

some shots from my older non DG version which I just got

after only having this lens for 1 day I am already in love with it

these are about 50% crops taken with a 40D, ISO 400, F5.6

Does the Sigma 500mm take a teleconverter well? How does it effect it's IQ?

I suggest you go back & read posts 41 to 45 in this thread..

Yes read my other posts. The 500 f4.5 should give a 500 f6.3 which works on 1D bodies...but it does not always, Sigma have made no attempt to make it work. But with the pins taped it works really well on 1D and 5D bodies. 2xTC however is a load of c**p, no contrast, no sharpness, no AF.

I have the tamron sp pro 1.4 & 2 TC, neither of them will AF on the 1D MKII without the tape trick which is strange

with the tape trick it works no problem, even the 2x does AF

I have been using it with the 1.4 and the images are pretty darn sharp, I have only used the 2x a couple times quickly and the sharpness suffers for sure, I just ordered a 2nd 1.4 to stack with the other one to see if that works better

re- Sigma 500mm and t-cons and AF

From the T-Con Sticky FAQ;
*NOTE, due to repeated reports and manufacturers statements of problems with AF
on 1D MkII bodies with the 500mm & 300-800mm with a 1.4X t-con, the list states MF only
However in my original tests with a 1D 4.5MP, the 500mm & 1.4X did AF
At this time we are not sure of what other lenses may be affected.
I'd be wary of the 800mm f/5.6 prime on a 1D MkII

And more detail from the discussion thread;

It is a problem, not only with the 500mm, but also both Sigma 800mm lenses.

Spring is here and so at last is some decent light. I set up a perch this morning and was rewarded with some coal tit and blue tit shots. After Sigma replaced the worn out focus motor on my non-DG 500 it's now extremely fast and works well with the accurate focusing algorithms in the 1 series. These are all with the 1DMk2 at ISO 400, f/6.3.

amazing shots my friend, i'm really considering such lens, im sureprized that the 1d mark 2 is pretty noisy @ iso 400 compared to the latest sensors(7d, and 1d mark 4)

Two more from last weekend. Again, both with the 1DMk2 and both at ISO 400, f/6.3.

Some from Easter weekends Formula 3/GT meeting at Oulton Park using Sigma 500 and 1d Mark iii

Nice motorsport shots, did you use a monopod and what settings......no exif attached

Thanks, Yes monopod used.. ISO100 shutter around 250/320th and aperture varies f/5.6 to f/8
Cheers

Not much action in this thread of late, so here's another contribution from me, a red-whiskered bulbul in Mauritius. This 500 is a faithful addition to my travel kit, fitting neatly as it does up the center of my Lowepro mini-trekker classic with enough space around the sides for two cameras and a couple of smaller lenses. I've never had any problems travelling by air with this kit.

1DMk2, 1/60s, ISO 400.

If you use a Kenko DG 300 PRO with this lens and a nikon d5000 would it auto focus?
Thanks

So, everybody get a Canon by the end of the day?
