Sigma has been on a tear as of late. Since late 2012, the company has put out a highly regarded 35mm f/1.4 lens, a novel USB dock that lets you calibrate lenses at home, and a revolutionary 18-35mm lens with a constant f/1.8 aperture (shown above).

It appears Sigma is only just getting warmed up: new rumors suggest that Sigma may be building a 24-70mm zoom lens for full frame cameras that boasts a constant f/2.0 aperture.

“Commerce makes progress. Fortune passes everywhere.” – Frank Herbert

A few years ago I was accused of being a Sigma hater. (For the record, I did hate their quality control and so-called repair service at that time, and I didn’t hesitate to say so.) For the third or fourth time in the last year, I’m about to be accused of being a Sigma fanboy.

Review: The Sigma 35mm f/1.4 DG HSM is Solid, But Hope For a Purebred

sigma35.0513.D31_9249

When I first began looking at the new Sigma 35mm f/1.4, I made judgements about its quality. “It’s plastic, yuck.” “I bet that focus control feels like a rusty zipper.” “The AF selector switch will tick me off.” “It won’t match the speed of my Nikon’s and my focusing tendencies.” My preconceived notions were that I was set for a so-so experience.

Rechip Old Sigma Lens So That It Plays Nicely with Your New Canon DSLR

armysurgery

Older Sigma lenses that were designed for Canon EOS film cameras often don’t work correctly when mounted onto a new EOS digital SLR, even though the newer bodies still use Canon’s EF mount. If you’re an owner of such a lens, you might have heard that you can send it in to Sigma’s service center for them to rechip it in order to make it compatible again.

Did you know that those of you who are handy with electronics can actually do the rechipping yourself at home? Photographer Martin Melchior recently did this with his Sigma 70-210 f/2.8 APO lens, and says that anyone with basic soldering skills can do the same.

Sigma DP Cameras Hacked to Play Nicely with Leica M Lenses

sigmadpleica1

Sigma’s DP1, DP2, and DP3 cameras are known for the fact that they’re compact cameras with beastly APS-C Foveon sensors inside. With such novel sensor technology at their core, comparatively less is said about the f/2.8 lenses on the front of each camera.

Some folks over in China decided that they wanted the glass of the camera to be just as hardcore as the sensor within, so they figured out how to modify DP cameras to offer an Leica M mount, turning the bodies into interchangeable cameras (and proper mirrorless cameras).
