What kind of proof could OP really offer? This kind of stuff is, by definition, deep into the realm of qualia.

• Since you guys are, effectively, a third-party repair service, I assume you don’t have access to any “official” repair guides for lenses or your other equipment. Once you’ve identified a lens as being decentered (or what have you) how do you know what to do to fix that? Are there a few basic optical and mechanical principles that you can just learn and then apply over and over? Or is it trial and error with every new lens model that comes through the door?

• Once the Sigma 50/1.4 comes out will you do a blog post comparing the offerings in the 50–55mm range? It seems like everyone’s hoping the Sigma will be an affordable alternative to the Otus 55/1.4. (You should throw my $90 Canon 50/1.8 into the mix just for giggles.)

• How often does Roger’s anesthesiology background come in handy?

I have a question for Tim. Your recommended tripod looks good, but do you have a recommendation for a head that’s Arca-Swiss compatible?
