Back in January, Panasonic announced a new line of converters for their Micro four thirds cameras which included a fisheye, a macro, a wide converter (which modifies their 14mm lens to 11mm), and a telephoto (which converts their 42mm to 84mm). The only one that interested me was the wide converter because I already owned the 14mm. At $130, the decision was a no-brainer. After the obligatory wait of four and a half months, it finally showed up on Amazon this week. I bought one a couple of days ago and it arrived last night.
If you own Panasonic’s 14mm lens you’re getting the equivalent view of a 28mm lens on a 35mm camera. The DMW-GWC1 converter changes the view to 22mm. In the days of film, I frequently used the 903 SWC Hasselblad, so I’m already comfortable with a view this wide.
This morning I took my G3 over to Sag Harbor for some pictures with the converter. When I opened up my RAW files in Photoshop an hour ago I was pleased to see pictures that were surprisingly free of the artifacts that you might expect to find with a lens converter. This picture, by the way, was photographed handheld @ f5.6 at only 1/50 second. You can click on it if you’d like to see it a little bigger.
I’m not sure yet if the profile for the converter is supplied in the most recent ACR upgrade from Adobe, but you can easily correct for any vignetting, fringing or distortion manually in ACR. With my first pictures (including the one up above), I didn’t find any of that was necessary. Of course it’s likely that under more challenging lighting or compositional situations, some correction would be called for.
Drawbacks to the converter? Well…if you’re only spending a $130 for a 22mm field of view, you can’t demand perfection. (I used to spend about that much for the filters on my Hasselblad.) To me, the biggest issue is corner to corner sharpness especially if you want to shoot wide open. Stopping down isn’t a big deal for me since I already tend to do that with prime lenses. If you do find a bit of fall-off in terms of sharpness, you can compensate for it in Photoshop.
Once you take your converter out of its box, it easily twists onto an adaptor ring (supplied)–which then screws onto the front of the lens. The converter doesn’t come with a pouch, but it does have the front n’ back caps. Mounted on the 14mm on the Panasonic G3 the camera is a bit too large to be truly called a “point and shoot”. I’m fine with that because it’s ergonomic. Even with the converter attached, the camera is considerably smaller and lighter than any 35mm camera.
btw– you can’t screw a filter onto front of this converter…so be aware of your bare glass at all times.
Footnote: Despite the fact that I was able to order a converter on May 14th, it’s once again listed as unavailable at the Amazon website. My advice is keep checking if you’re trying to locate one. Mine, by the way, shipped from J&R Music and Computer World, through Amazon.
