Lensbaby 3G - Review & Sample Photos @ PopPhotoMag
Popular Photography Magazine has recently reviewed the Lensbaby 3G and write;
“It’s a different breed of Lensbaby, but the 3G is a Lensbaby nonetheless. Just for fun, we attempted to analyze the distortion of the Lensbaby 3G using DxO 2.0, and the results were off the chart! (We’ve included several DxO dot-pattern target shots, to give the reader an idea of some of the distortions possible with the 3G.)”
Sigma APO 300-800mm F5.6 EX DG HSM
Large aperture ultra-telephoto zoom lens gives an equivalent field of view to 1600mm for the Four Thirds system.

The very latest lens coating technology and lens design reduce flare and ghosting, a common problem with digital cameras. Two ELD glass elements in the front lens group reduce chromatic aberration to a minimum and also ensure high optimum image quality. The overall length of the lens does not change during focusing and zooming, ensuring convenient handling.
The HSM provides ultra quiet, high-speed autofocusing as well as full-time manual focus override. This lens is designed to accept a 46mm circular polarizing filter in a rear filter holder.

Sigma Launches Website for Sigma Users
Sigma are now leading the way with third party optics designed for these modern electronic cameras. With this vastly increased quality, along with the number of ‘new’ photographers, we at SigmaUser.co.uk thought it was about time for a dedicated, independent website where users of Sigma’s equipment can exchange views, techniques, ideas and generally share their knowledge and show off their images.
So we have put one together!
It features:
Leica Tri-Elmar-M 16-18-21mm f/4
>> PRESS RELEASE
Due to the minimal distortion and barely perceptible field curvature, it can be recommended for highly demanding architecture photography even at the 16 mm setting. Used on the digital M8, it produces the image effect of a 21 - 28 mm lens, still enabling extreme wide-angle views.
