Bought this monster a long time ago by mistake. The listing was meager and I was under the mistaken impression it would fit the 645 system based on a dumb conclusion by me. Anyway it sat in the back of a bin for quite some time while I got involved with other things. It wasn't a huge amount of money so "oh well"... Digging through bins I came across it the other day and says "hmmm maybe...." found the appropriate reverse ring and a helicoid to get pretty close focus.

Looking pretty good!
A lens that often draws my attention is the Mamiya 140/4.5 macro for RB67. They are very cheap in Japan. Unfortunately the adapter for Sony E is quite expensive.

Lovely blossoms!

Is that larger, lavender flower a rose? I love the light in the second photo in your most recent post.

Thanks! The blue plant is a violet (viola odorata). The lighting on that shot you liked was actually the most basic. It is just sunlight diffused through a (rather dirty) polycarbonate patio roof. The others shots of the rose I was playing with a mirror bouncing sunlight to tryfor more dramatic lighting.
