The post above with the Nikon mount Tamron 90 f/2.8 macro inspired me to get mine (EF mount) out this morning and try a few with the G1. I had just experimented with it when I got the EOS adaptor, but I find that its quite nice on the G1. Of course you have to change that aperture on an EOS body, but, for now, I can live with that as most of my macro is done on my own farm--with several EOS bodies nearby LOL. I do have other macro choices for the G1--extension tubes on FD lenses being what I've used a bit in the past.

It has a bit of oversharpened look due to the little white dolallies on the seedhead, but its only sharpened lighly in Lightroom. Notice that little critter down in the bottom right--very interesting at 100%--not sure what it is.

And--for good measure, while shooting around yesterday with my huge Sigma EF mount 20 f/1.8 on the G1 (more or less being sure I loved the fast 20 on an m4/3rds).

Keith, I love your bokeh shot above.
