Sigma continues to impress me with their updated versions of pro and semi-pro lense for D-SLRs. They provide excellent value with pricing below the Nikon and Canon versions while not sacrificing image quality. Their new 24-70mm f/2.8 full frame HSM (same as USM or AF-S) is no exception...

Welcome to DPS 7-04--the nikondigital.org newsletter.We've got some great new product announcements and updates as well as the results of our Sigma Lens field test for you in this issue, plus an upgrade to our November Botswana Safari and an announcement of our Texas Bird Photo Safari for next April. Mixed in you'll find some useful photo tips we picked up in Texas this April.

We just finished another successful Texas Bird Photo Safari. I'll be writing more later in the week but since so many of you are curious about the Sigma 120-400mm Telephoto Zoom lens I wanted to let you know that it was a complete success.
