Sigma 30mm F1.4 EX DC HSM

Review Date: May 19, 2009 Recommend? yes | Price paid: $600.00 | Rating: 9 

Pros: damn sharp in center at 1.4, very fast and accurate AF, very-very-very strong to flares, low weight, compact size, price tag, versatile FL for indoor shooting, lens hood included
sharpness quickly falls off to corners - not the best lens for full-length portraits, CA (but not much), DC lens

That was my upgrade out of 18-55 kit lens for canon crop body: sig 10-20 + sig 30/1.4. I bought it especially for shooting my new-born daughter indoors w/o flash. So the lens justified my hopes in terms of 1.4, AF speed and FL: many times I admited that 50mm would be too long for crop body to make a good shot indoors.

When the word 'strobism' started to sound in my ears, I noticed that 30/1.4 is very strong to optical flare. Many of my shots contain direct sun and look pretty well.

The strongest disadvantage of the lens is it's sharpness fall-off. If you shoot a person and the face is not in center of the frame, be sure, that you are stopped down enough: f/4 or narrower aperture. I also noteced a strong field curvature with this lens: when I was focusing on someone's face with central point and then recomposed my image, I got misfocus in hight percent rate. But when I used perepherial focusing points (on 40d they worked just fine) I had significantly better results.

Sigma 10-20mm F4-5.6 EX DC HSM

Review Date: May 19, 2009 Recommend? yes | Price paid: $640.00 | Rating: 9 

Pros: wide angle, not flare prone, ability to use filters, tank-like build quality, price tag, complectation
DC lens, not as sharp as sigma 12-24

That was my upgrade out of 18-55 kit lens on canon crop sensor body. I bought this lens especially for creating panoramic pictures and made a choice between sigma and canon 10-22 based on reviews, price tags and complectation - lens hood and a pouch included in sigma's pack are useful. It's quite strong to flares as already mentioned in many reviews - so it's a big advantage for panorama creation. It has no CA on longer end (20mm) even wide open, though 5.6 is not very fast to call it 'wide open', imo 8]

I did not choose my specimen out of many copies, just went to a local shop and gave them money. Image quality was good enough to sell stock photographs. Though, now I'm with FF body and use sig 12-24 instead of this glass. Have to say that 12-24 is sharper, especially in corners. It also seems that I like pics from 12-24 more, mb FF sensor is the reason (5d2 vs 40d).

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

Review Date: May 18, 2009 Recommend? yes | Price paid: $1,000.00 | Rating: 8 

Pros: f/2.8, very fast autofocus, tank-like build quality with internal focusing and zooming, nice price tag and finally.. it is black!
my copy gave me soft pictures with yellowish color cast, image quality non as good as 85L

It was my first telephoto lens. When I bought it, I had 30/1.4 and 10-20 on a crop sensor canon body, so I had a lack of longer FL. So I made a choice between sig 70-200/2.8, canon 70-300 IS and sig 100-300/4. I didn't want to be payed with attention so I desired not to look at any white canon 70-200. Sig 70-200 won the contest because of its better build quality and faster aperture.

After a year of use I found it as a good sports shooting lens with it's very fast and accurate autofocus: with iso 3200 you'll never see it's softness even at 100% 8] As a portrait shooting lens it disappointed me with it's softness even at f/5.6@70mm. Though it's got nice bokeh.

At last I bought 85LII and sold 70-200. Now feel good, stunned with IQ of 85 lens. Looking at 200/2L to get longer FL, though don't suffer much without it.
