Sigma 30 f1.4 micro four thirds mount  (1 of 2)

As I continue to research micro 4/3 lens options I was surprised to find that the Sigma 30mm f1.4 lens comes in a micro 4/3 mount. The 30mm f1.4 lens was original designed for APS-C size sensors cameras. It’s a great little lens for the price but it is a little soft in the corners and produces noticeable vignetting wide open on an APS-C body.

I’ve used the APS-C version of this lens for years and had no problems with image quality. A micro 4/3 sensor would likely make this lens even better because the sensor would only be using the center of the Sigma 30mm f1.4 lens which would reduce vignetting and increase corner sharpness at f1.4. Admittedly the lens is a little on the fat side for a Panasonic GH4 body, but a 30mm f1.4 lens for $300 sounds pretty tempting.

I haven’t found a whole lot of information on the micro 4/3 version of the Sigma 30mm f1.4 so it’s a little bit of a mystery. Have any of you given this lens a try? This older version is kind of unique since Sigma doesn’t produce any of their newer “Art” lenses in an M4/3 mount. I might have to give the Sigma 30mm f1.4 micro 4/3 lens a try.

UPDATE: I was having trouble finding any real info on the Sigma Panasonic mount so I sent an e-mail to Panasonic to get a little more information and they sent me this compatibility list. They also let me know that the Sigma is a 4/3 mount not a micro 4/3 mount (apparently I still have a lot to learn about Olympus and Panasonic cameras) and requires an electronic adapter to get things working. With the adapter attached all electronic features including AF work on the Sigma 30mm f1.4 and the electronic adapter only adds about $45. I might still have to give the Sigma a try.
