fd-EF adapters that give you infinity focus use a glass element usually about 1.33x multiplier even on the good quality glass. So totally negates the gain given by the adapter.  I don't see this as usable for FD glass, hopefully they will make an FD to m43, but until then for me it will means complete new lens set.  Initial excitement wanes but still excellent product.

This is a really exciting product, however...  there are a lot of posts getting excited about using all sorts of cheaper lenses.  But from what I see the adapter will turn your cam into an ef mount, alpha mount or leica r mount.   You are then going to have to adapt your FD or what ever legacy lens to one of those 3 mounts.  Not so easy and not so straight forward as many need extra glass for infinity focus and finding good ones is more difficult.  Also you then have 2 adapters, and possibly more 'play' in the lens mounting.       I have several canon FD lenses and would love to have them at full frame equivalent on m43, but I'm not sure the current road map for this gives me what I need.  I hope I'm wrong.  But this may not be aas good for legacy lenses as it seems at first.   Also I don't think it will make f2.0 into f1.4 lens.  It will give the equivalent brightness of a f1.4 due to conentrated image, but not change the dof characteristics, surely it will still give the original characteristics of the lens.  dof will be as f2.0.  When the website talks about .71wider it is talking about .71 wider on a s35, which brings the lens back to 50mm full frame, so when it talks about 1 stop increase in apeture, again bringing it back to FF equivalent??   So will this mainly be for current lenses(ef etc) or can we use legacy glass?
