[Leica] new Puts article

[abridge at gmail.com (Adam Bridge)]

Wait a minute now. For a given lens the DOF is independent of the
cropping factor of the sensor, right? So if you use existing M lenses
on a digital M with an APS or somesuch chip then the depth of field
will be the same for a given f-stop but the crop factor will still be
in play.

Isn't this right?

I admit that Erwin's article didn't make a whole lot of sense to  me.
I read it once last night and after my mind tried wriggling around all
of it . . . I was confused. Maybe it'll make more sense in the light
of day. But some of the things he was saying didn't seem to match
experience very well.

Oh well . . . light is particles. I'll stick with that.
