Thanks. So you wouldn't consider replacing a lux with a Sonnar. Sounds like the lux brings a lot of performance advantages to the table (which it should, given the price!)

Anyone compare CZ 50mm f/1.5 Sonnar to the Leica Summilux 50mm f/1.4 (latest version?) the lux has better contrast and less SA at large aperture, it also has much less busy bokeh at full aperture. the lux also has better corners stopped down (at least on a leica, not sure on an unmodded a7). no, definitely not. the zm is one of those lenses where you have to be careful about your background and stop down a fair bit to not have ugly distracting bokeh as well as always being a bit weak towards the edges. the lux has some character but is doesn't ever really surprise you with weakness imo.
honestly, even ignoring price, size, and focus method i would choose the lux (on a leica sensor) over the otus, sigma art, ZA FE 50/1.4, and the new cron AA (though i haven't shot with all of those). I would not mind trying which I had before in the past is a Leica 50mm 1.4 lux pre-asph. I wonder how it would be on our Sonys. Yuk price is stupid high at least 2k
you can get them for 1.2k if you have a bit of patience and don't demand collector grade condition (don't know why you would). it seems about as troubled by the sony sensor as the zm 50/1.5 is.
personally, I like it better than the sonnar for portraits, but opinions vary – the lux pre-asph produces cat's eye bokeh where the sonnar really never does (it also lacks the modern coatings/contrast of the zm).
