Hello: Probably, it has been discussed somewhere but I could not find any fresh postings. I am currently transitioning from digital to film cameras. I will still have the digital however to shoot my daughter etc. I bought a Leica M7 and a few lenses. 90mm, 28mm and 15mm but I am shopping for a 50mm. I have two options: Summarit 50mm f2 or Summilux 50mm f1.4 non-asph. On ebay I found a few of these lenses. Summicrons are about $1200-$1500 and Summilux is around $1800-$2100. still debating... does any one have experience with both of these lenses? if so, would you please share your experience. Thanks, Serdar.
