I've had my pentax 67 for 6 months and am amazed at the quality of slides I get from the 105 2.4 smc lens. I am ready for a longer lens and I am looking at the 165 ls.Can the 165 ls be used with the focal plane shutter instead of the leaf shutter or is it limited to ls use only? Mike walkerm@pacbell.net

Don't cock the leaf shutter and the 165ls can be used like a regular lens with the focal plane shutter. I've seen charts listing the ls lens as being a different optical design than the non-ls one, I seem to remember 4 vs 5 elements. I've never seen definitive results on the optical performance of each.

Set the LS lens to the "o" setting (past the 1/60 sec setting), cock the lens's shutter once, and you can use it like a regular lens. (Or you can cock the LS lens first and then set it to the "o" setting; same thing).

Set the LS lens back to one of its shutter speeds (60, 125, 250, 500) and the body to 1/8 sec or slower to go back to normal operation.

This is for a P6x7, I assume a P67 is the same way.
