Thanks! Yeah, the price of the TTA is pretty amazing. How do you find it compared to the Lux in respect to size, viewfinder blockage, etc.?
The TTA is much larger than my BC Lux 50 ASPH (49mm filter thread vs 43mm) but not so much that it's troublesome to me. I now have a number of M lenses that are all roughly the same size and weight (and all have 49mm filter threads): TTA 50/1.4, APO-Lanthar 35/2 and 50/2, Distagon ZM 35/1.4, and APO-Summicron-M 75/2. This size and weight feels normal to me. It's interesting that the Nokton VM 50/1.2 just slips into the zone of unacceptability even though with a 52mm filter thread it's only slightly bigger. And even odder that I'm fine with the 7Artisans 28/1.4, which also takes 52mm filters, perhaps because the 7A is longer but thinner than the Nokton.
I suspect I'm much more tolerant of viewfinder blockage than many Leica users. At infinity, the TTA without a hood blocks no more than 5% of the bottom right of the frame, with a straight vented hood it extends about 15% (though one can see more than that through the vents). Viewfinder blockage is a significant issue with the 7A 28 so I either use the Visoflex or an external 28mm viewfinder with that lens.
One thing you'll like is that it has a focus tab but it also has a knurled focus ring so the tab is not a deal breaker for me whereas it was with the standard Lux 50 ASPH.
