I'd like to have my personal lenses checked for optical performance and benchmarked. Despite assurances to the contrary, I've always been concerned about sample variations. Specifically, I'm curious if my 35 Summilux ASPH is performing up to par. Any suggestions would be appreciated. David W. Almy Annapolis
