Pros: Nice bokeh all the way; sharpness at 70mm
Cons: not good at 210mm
Sharpness: 5    Aberrations: 3    Bokeh: 9    Handling: 6    Value: 4    Camera Used: Nikon D2X; Nikon D40    Autofocus: 5    New Or Used: Used   

Nice built from Sigma. Overall images are good, but lacking sharpness at the long range due to some spherical aberrations , I guess, even in the center of the frame. Bokeh is excellent. Manual focus is not very precise, it is too short path from closest to infinity and the ring is a bit loose. It's a standard kit lens quality but a fantastic lens for the price, I paid mine 12 euros plus shipping.

close focus 210mm:




70mm, good sharpness:




not really sharp at 210mm (with no handshaking...):

Pros: small, fast AF, good colors, light, good price
Cons: only for begginers, who need zoom lens for low money
Sharpness: 8    Aberrations: 5    Bokeh: 7    Handling: 7    Value: 7   

Great lens, if you whant zoom lens with macro and dont have money. Great lens for begginers.
How you can see on pictures, great color, good sharpnes, but you need great eye to catch the best scene in best moment.
Motor for AF is little to loud, if you compare with other lenses.

If you whant shoot amater-professional photos, collect money, and buy something like smc 55-300 or tamron 70-200mm.

Pros: everything
Cons: none

Definitely best buy lens for the money (NOTE: mine was bought in Japan). Sharper than Tamron 70-300. But as far as I know there are some differences between those sold in Japan and rest of the world.

Pros: Small Size
Cons: Everything Else!

This arrived through the door today, and is already back on ebay. Lovely proportions, but what shockingly bad build quality! Feels flimsy and cheap. Focus ring was so light and loose that it wouldn't stay set!

I at least thought the optics might be good, but no, they're not. At the long end it's woefully soft wide open, and all through the range it suffers with purple fringing and an odd glow around bright areas.

Had it actually been a marginally fast lens I'd have forgiven it, but with such a large max aperture it isn't really practical to stop down for sharpness in anything but the best light.

Contrast and colour is however pretty good, at least they're not bad anway.

Can't reccomend this lens to anyone unless they desperately need tthis focal range and there is no other choice.

Some Samples and test can be found here.

Pros: Compact, cheap
Cons: Lacks precision feel
Sharpness: 4    Aberrations: 5    Bokeh: 4    Handling: 1    Value: 1   

Could not resist it when I saw it on eBay going for about $20. So I might be looking at a bad specimen.

However I also have the Pentax DA 50-200 ED WR and comparing the two there is really no contest. The Sigma is heavier, bigger and lacks the intangible 'precision' feel. Ergonomically it is also pretty poor - why have a wide prominent focus ring on an autofocus lens ?

It is not really that bad, although a bit unsharp at 210mm wide open and contrast is not all that wonderful.

Works perfectly with a K-7. I am yet to test it properly in anger, but I don't think that I'll be keeping it.

Update :

I just could not get to like this lens. Mercifully it is now gone to some other eBayer. It was cr*p. Sample photos are here http://www.flickr.com/photos/kh1234567890/collections/72157626443077020/

Pros: Compact size, fast AF, Great Bokeh
Cons: Indoor shooting is if'fy

For a nice price saver zoom lens, this lens has it all. Great shots, great focusing speed, really sharp... and not to mention one of the more compact zooms that you will find for this zoom range. Not big and clunky like many of the other 70-200 zooms you will find out there.

Here are a few sample pictures that I have taken with it...

Overall... I say this is a great lens to have before stepping up into the big leagues of the F2.8's.

Pros: light, smaller than most 70-210, good colors, macro
Cons: not for indoors

For some reason this lens is not well known although, to my opinion, it is a very decent performer and one of the best budget 70-210 zooms. It is very light and much smaller than, for example, Pentax F70-210. It is capable of producing great portraits with beautiful bokeh at around 150mm. Macro is 1:4.5 which is not very impressive but still very helpful. The downside is that this lens is not well suited for indoors but for this price you won't get a faster zoom of this range anyways. It is pretty sharp, just a bit behind Pentax F70-210 as far as I can compare -- you really need to look full-size to notice the difference. Overall, it is a nice fully automatic and very easy to handle zoom which costs half the price of similar Pentax lens.

Here are some photos shot with this lens:
