In the runup to PMA, Sigma firmly declared its commitment to digital photography with a whopping thirteen lens announcements aimed at digital photographers. Of these new models, 10 were APO lenses which are variations on existing designs, but with lens coatings that have been specifically tweaked for the best digital performance. These models all offer a full 35mm image circle, providing compatibility with both 35mm film and digital camera bodies. The remaining three models were engineered specifically for digital cameras with an APS-C or smaller image sensor, offering potential benefits in weight, size and image quality as compared to a lens designed for the larger image circle of 35mm film.
All of these new lenses were on display at PMA (although we did miss getting a photo of the impressively small 18-200mm F3.5-6.3 DC lens, which can be seen in a press photo from our coverage of the announcement. Sorry!)
We also saw an interesting macro ring flash announced last September, the EM-140 DG, which is compatible with both 35mm film and digital bodies, and is compatible with Sigma-STTL, Canon-ETTL/ETTL II, Nikon-iTTL, Minolta-ADI and Pentax A-PTTL flash metering systems.
All things considered, Sigma's booth really impressed, with a vast range of products catering to pretty much anyone who owns a digital SLR. We're looking forward to trying out some of these lenses ourselves in the future, and seeing how they fare in terms of image quality. We've been very pleased with some of Sigma's lenses in the past - if the new models are as good, they'll offer excellent alternatives to lens models made by the camera manufacturers themselves. Considering that a good array of lenses is generally the most expensive part of a digital photographer's investment, third party glass can be a great way to get the most mileage for your money...
