I hear the Thorlabs glass is not up to par, you might wanna double check me on that one.

Which glass are u gonna buy from POC and how much does it cost?

For 35mm adapters to get the ever illusive Depth of Field everyone is talking about these days.

Pretty much so, at least for us vid cameras users.
