I have to say I love my Contax G 28mm lens on the m4/3 format.
I’ve posted a few examples here and it’s a wonderful surprise to be able to use this lens. It’s by no means as perfect as it was on the ol’ rangefinder camera that it was originally suited for but it sure is wonderful to use on my GH1 and tack sharp with beautiful contrast. For those who may still be on the fence, I put together a very simple no frills video to go over the steps of cutting the legs from the Contax G 28mm lens and a quick tip to make sure your Metabones adapter is nice and smooth. If you are super brave you can even do this on your Contax G 21mm lens as well. It’s well worth it if you take the risk!
