Product Description

Sigma Corporation is pleased to announce the launch of the new 17-70mm f/2.8-4.5 DC MACRO lens. It can be used with wide variety of subjects and it is an ideal large aperture standard zoom lens for digital SLR cameras featuring APS-C size image sensor. This lens has a minimum focusing distance of 7.9.. (20cm) throughout the entire zoom range. Maximum magnification of 1:2.3 enables close-up photography like a macro lens. The new lens design and multi layer lens coating reduce flare and ghosting, which is a common problem with digital cameras. A Special Low Dispersion (SLD) lens and two aspherical lens elements provide excellent correction for all types of aberrations and produce a high level of optical performance throughout the entire zoom range. This lens offers a large aperture of F2.8 at 17mm wide angle and yet it is compact, with an overall length of 82.5mm (3.2..) and diameter 79mm (3.1..). It performs superbly even in relatively low light conditions indoors or at dusk. The lens design incorporates an inner focusing system, which ensures fast AF speed as well as prevents the front of the lens rotating, making it particularly suitable for use with circular polarizing filters and petal shaped lens hoods. This lens is also equipped with Zoom Lock Switch that eliminates ..Zoom Creep.. during transportation.

I recently got this lens for my Minolta 7D, but wish I had made the investment a long time ago! I'm always stepping back, stepping back, oops, my back is against the wall, trying to get more interior architecture in the frame. That is, until I got this lens! I have a 28-80 lens for a Minolta film 35mm camera that just isn't wide enough, epecially with the crop factor working against me. The versatility of the Sigma 17-70 now allows me to get everything I need in the frame and with very high quality -- plus the additional macro ability is something I didn't think I would use much, but have found the extreme close-up option really fun to experiment with. I don't see myself changing lenses much ever again!

I compared this lens with the excellent Sony 50mm f1.4 lens (arguably a bit unfair since this is a prime lens). The camera was a Sony a350.

Build: Smooth secure operation. No complaints.

Flare: I had heard that this was impressive and I could not induce significant flare under any circumstances - even without the included hood. Great!

Chromatic aberration: If I "pixel peeped" I could sometimes see a pixel width or two of color, but no worse than the Sony 50mm. Really good!

Resolution: To test this I shot text on a wall at various focal lengths from wide (17mm) to telephoto (70mm) at wide open and f8. The results were quite comparable to the pictures with the Sony 50mm lens except at the extreme edges wide open where it was a bit soft. However, at 17mm f2.8 the picture was quite soft at the edges and somewhat soft even in the middle. In this test situation, the 17mm f2.8 shot ended up at less than 3 feet from the wall. This is a bit extreme and I have not yet repeated this test at a more realistic distance.

However, does this matter if it is soft at 17mm f2.8? On a recent trip to Arizona, I shot a lot at 17mm, but none of the shots were at f2.8. So I think that this is a minor point and probably typical of a lot of other zoom lenses as well. Because of the high resolution of the Sony a350 (14M pixels) any focus errors readily show up, but this can't really be blamed on the lens (the Sony 50mm sometimes misses focus also). I recently saw a discussion where focus errors were called the dirty little secret of the (various) SLR makers. Oh well, considering how fast the SLR cameras focus, I suppose it is amazing that any shots are in focus.

If you have a Sony Alpha, this lens is a nice step up from the standard Sony 18-70mm kit lens. It's faster and sharper than the kit lens, and has a minimum focus distance of only 8 inches.
