Sigma 120-300mm f2.8 EX DG HSM

Review Date: Jul 9, 2008 Recommend? yes | Price paid: Not Indicated | Rating: 10 

 
Pros: Price, internal zoom, fast focusing, colour, sharpness, boken, decent hood.
Cons:
Weight.

I sold my Sigma 300mm f/2.8 prime to buy this baby. Main reason being I needed the zoom option. I've not regretted it. Sharpness is brilliant and is on a par with Some of Canon's cheaper primes, namely the 70-200 f/4 and the 300 f/4.

I've only used it with a 1.4x converter and I'm delighted with the results. (Some recent - http://www.eos-forums.com/index.php?topic=22580.0 - mine are first in post)

One thing that really tipped me in towards this lens is the internal zoom, no more worrying about the zoom action sucking in dust.

I do have an issue, which might be my camera (Canon 40D). Sometimes, say 2-3 times in a days shoot, I will miss a shot because the lens goes hunting and focuses very slowly.

Take two lens on a shoot? I just take this one Smile


 
Sigma 70-200mm F2.8 EX DG APO MACRO HSM

Pros: Build, Price, Macro, Lens collar, works well with 1.4x, Quiet, fast focusing.
Cons:
Soft at f/2.8.

It's really a shame this lens is soft at f2.8, I was hoping for a little more. I did a test comparison along side my Sigma 120-300mm f/2.8, and the 120-300 is far sharper at the 2.8. But as stated here, it's OK at f/4 and above. If you never really go as low as f/4 I'd recommend, if using Canon, that you get the 70-200mm f/4 L.

Yes I'm a little disappointed but will be keeping it, for the time being, as it's still a cracking lens. The macro for me works really well as does the HSM focusing.

Come is a really good case too with shoulder strap.

Pros: Great price, quiet focusing, compact size, tac sharp, contrast and saturation are good.
Cons:
Weight, tripod mount. no IS.

I've got the newer version, the EX DG HSM.

I'm so delighted with this lens it performs brilliantly. It's pin sharp, even at f/2.8. Focusing is fast, maybe not as fast as the Canon version, but then again it's half the price. Ohh and just because it's half the price doesn't mean your getting half the lens.

The lens hood is well designed and made from alloy and not some cheap plastic.

I do have some small issues though.
I noticed that sometimes the lens was hunting to focus on things, admittedly I was trying to capture planes landing against a grey sky, I did have it hooked up to the Canon 1.4x converter at the time so there might be a compatibility issue. I've since used it with the Sigma 1.4x converter and there was no hunting issues.
The tripod mount so needs to be bigger. Also there's no image stabilization but that's no big deal.

Over all this is a fantastic fast lens.
