Sigma 18-50mm f/2.8 EX DC SLD ELD Aspherical Macro Lens for Olympus and Panasonic Digital SLR Cameras [Posted on 2007-07-03]
I have used Sigma lens for many years on different camera. I never owned one of their best until now. This is an excellent lens. I would reccommend it to any one. Very sharp & plenty of contrast. I am 100 percent happy with this lens & the excellent service I received from Amazon. They delivered right on time as promised.
Good glass at a good price [Posted on 2008-01-27]
Sigma makes their lenses in Japan using much of the same machined construction techniques we have always been used to. This four thirds Olympus mount macro was my first choice over the more expensive Olympus glass.
This is a large lens with a big front element. AF works fine, it isn't too heavy, the manual focusing is smooth, and the contrast and color seem fine. But I am having a hard time really evaluating this lens on the inexpensive, feature rich, somewhat oddball and discontinued Olympus E330. With this lens and also the cheap Chinese made Olympus lens that came in a kit, there is a noticable lack of "tack" sharpness in the images. I think this is the sensor or the camera itself and not the lens.
Barrel distortion is small. The lens retains decent focus throughout its range, though critical focusing may need a touch up. The mount is smooth and the appearance and quality is good. The useful range is like a 36 to 100mm lens which is useful for table top and product shots which is what I bought it for. I see little evidence of coma, flare, or pincushioning.
I am very eager to try this lens on the new E3. I have other Sigma lenses that I have liked, including the very excellent Minolta mount 24mm macro - a wonderful lens, so sharp, distortion free, fantastic. Now I hope for an 11mm for digital that will do the same thing.
Impressive Quality and Performance [Posted on 2008-08-05]
After long research felt skeptical about the quality at F2.8 but decided to get it. I am amazed with the pictures that I took with this lens at all apertures. When compare to the kit lens even at F2.8 the pictures taken using Sigma are way sharper, few reviewers mention about soft image at F2.8 but perhaps my results are different as maybe the kit Olympus lens which is made in China failed quality control and as a result I end up with bad lens. I accepted the quality as standard and would probably never know. I'm very happy with this lens and highly recommend them to anyone.
