Is the Sigma 50-150mm f/2.8 EX DC OS HSM Lens right for you? Learn all you need to know in The-Digital-Picture.com's review!

At first glance, the new Sigma 50-150mm f/2.8 EX DC ($680, street) appears to possess an unusual focal length range. But when you do the math, multiplying by a 35mm lens-conversion factor of 1.4X, it becomes a more familiar-sounding 70-210mm equivalent.

Great zoom lens with large aperture! Being able to get telephoto with f/2.8 is what I needed and the lens produces great pictures on my Nikon D7000. Build is very solid, zoom and focus rings are smooth. Only issue is its a bit heavy, but what do you expect from lens with this capability.

Consistent Output; Durable; Fast / accurate auto-focus; Nice Bokeh; Strong Construction

Heavy

I really like this lens. It is my first "professional" grade lens and I am VERY impressed. The sharpness of my photos is a magnitude above that of the kit lens for my Canon T3i. Photos taken with this lens are tack sharp! I read some reviews stating that at F2.8 there is softness at the edges.

Much Cheaper Than L Glass; Quick Focus; Very sharp

Heavy; Large; Not For Full Frame Camera

I have been waiting for this lens for a year. Finally I bought it one week ago. Let me tell you it is a Sharp lens! Tamron and Sigma are catching up with Nikon and Canon. This is actually a pro lens to DX shooters with optical stabilization.

Great lens, I haven't came across any problems with this lens, it has a great focal length especially with a crop factor of about 1.5x. The only cons I can think of is it dosnt have the quickest focusing when it comes to sports, also i would of liked to see the manual mode button on the side, lastly...

I used to be an owner of a Sigma 50-150mm f2.8, before i got Tokina 50-135mm f2.8. Sigma had problems with front focusing, so i sent it back to service. They somehow managed to adjust the focusing, but after using it for a year I sold it, because the image quality of Sigma 50-150mm f2.8 was not...

HSM motor; EX built quality

focusing issues; image quality is just average

The build quality of the lens is excellent thanks to high quality materials assembled with very tight tolerances. The broad, rubberized zoom and focus rings operate both very smooth and even slightly damped - a rare characteristic these days.

Sigma's innovative approach to its lenses continues here with this addition to the DC range of cropped sensor only lenses. Designed to fit where the popular 70-210mm models fitted in on 35mm/full frame, we take a look at how it performs.

Excellent optical performance; Very good handling with fast AF; Compact with a supplied hood

Slight fall-off in resolution at the longest focal length; Distortion just noticeable at 150mm

Originally posted 2006-10-31 on Optyczne.pl Recently we published a review of Sigma 70-200 mm f/2.8 EX APO DG HSM Macro - the lens that has good reputation among many users. This is big, solid instrument designed for full frame cameras so we were not surprised that it performed well on APS-C DSLRs.

poor image quality at the edge for 150 mm; chromatic abberation should be smaller in APO lens; noticable astigmatism for focal length range from 100 to 150 mm; clear vignetting especially at 150 mm; significant front-focus with Canon 20D
