Hi Metric - I have mostly "L's" but I'm not hung up on them.
I came from Hasselblad when I migrated to digital so I wanted something as close to Zeiss as I'd been previously accustomed. I don't "collect" lenses, only buying what I really need. Each has to earn it's lunch. Of the 5 lenses I own, two of them account for more than 90% of my shots.
What subset of those who love all their photos have a bad case of L-itis?
