[xray]

I owned the 1st version for a few years after owning the 1st generation pre asph summilux for twnety plus years. I currently own the 4th generation. While the summilux 1st generation is a good lens it's not as good in the flare department as the 1st generation summicron. That said the 1st generation falls quite short of the 4th genration in most respects. The 1st version is less than stellar wide open suffering from considerable light falloff and slightly soft overall and noticably soft at the edges. It's all relative to ones expectations and needs as to what is best but for the money the 1st version is way over priced. Honestly I do not know what the attraction is for this lens other than for collectors. I've used Leica M profesionally for thirty eight years and the 1st version is one of my least favorite of all Leitz lenses. I also have a new CV 35 1.2 Nokton that i would much rather have than the 1st V and would take it over my 4th V if i could only own one 35mm. Save some money and find a clean 4th V or CV lens.
