Hi there, i thought i'd ask as i'm a little confused. when using manual lenses and the camera asks for focal length, is it asking for marked, or equivalent?

what's the maths to work it out? (it's a k100d super if that makes a difference.

also, if using a 2x teleconverter.... is that still 2x? or does the crop factor also affect that?

I may be wrong but I think you just put in the lens size, as in 50mm lens you input 50mm. No need for the 1.5x nonsense.
One day you'll find, 10yrs have got behind you.

ok so middle of the stated range. unless shooting exclusively at one end. thanks

if using 2x converter on a 200mm lens... input 400mm?

I would, but other people argue you should just use 200mm, as that's the lens
