Hi Reg When I started with the Leica R7, I had a SP Tamron 70-210, I put a LEICA R on it, swaping out the previous PK mount. It was quite good when stopped down and the mechanical adapter was pretty OK for a lens of that weight. I found a clear answer to your quest: http://www.apug.org/forums/forum52/53959-tamron-adaptall-2-mount-leicaflex-sl.html ; In a couple of words, the adaptall 2 for Leica is "R" or "3 cams". The SL uses only 2 cams and ignores the third cam. Only some products from Tamron were compatible with Leica R, please refer to the section Tamron here: http://www.summilux.net/r_system/autres_marques_f.html It's in french but there is a table that lists the compatible lenses, see if your "graal" is among these. Finnally, there is one adaptall quite affordable in the vicinity of my home (I can help to purchase, contact me off line, I'm not the seller!): http://www.phox-occasion.com/tabid/107/CategoryID/4/List/1/catpageindex/42/Level/a/ProductID/10332/Default.aspx IMHU, the prices over the FleaBay are a bit high to me on that item. ------------------------------------- Xavier F.
