[Leica] 7Artisans and TTArtisan lenses compared to some German versions

[imra at iol.ie (Douglas Barry)]

Thanks Frank, but I think I may have suggested before in another context 
that you just crop a small but relevant piece of the raw files that show 
any significant difference between lenses, together with a larger jpg of 
the entire image so that we get context, and post them to your gallery 
here on the LUG - or elsewhere.

I'll pass on the 7 Artisans and wait to see a few images on a Sony A7 
from the TTA to get an idea whether it would an idea to mull over. I'll 
have to wait to see whether it is a lot better that the Samyang 35 2.8 I 
have. I also have 35mm Zuiko and Pentax lenses with adapters, and a 
goggled 35mm Summaron which I've never bothered to try out as it wasn't 
a particularly marvellous lens. That pic I posted a day or so ago in 
Rome was taken with it but on my Leica M3.
