I’m kind having debate deciding which on to get, either Summicron or Summilux, I read review said Smmicron more sharper than Summilux. Since you own both can you tell the difference? vidmate

I have decided to test all my 50mm and 35mm lenses with film, and to print all the results on 5×7 paper, the test target was my son reading a book. The film medium on print was the best way to see real life results and absolutely no digital variable whatsoever. This, to me, is the most accurate possible test.

I’ve always heard V4 and V5 cron are basically the same aside from the focus tab/built in hood you mentioned. saveinsta
