[HUG ] Re: swc for sale?

I never could understand why anyone would re-state the effective Fl of a
lens because their sensor is not something else....

Do we say..... Hasselblad 80mm lens on a 6x6 negative is the same as a 50mm
lens?  No.  ( we may make the comparison, but it is never stated nor do I
ever remember it being used in this way....)

A 38mm Biogon is ALWAYS  38m.  Nothing changes that.  Nothing.

Try this, if you are trying to make a comparison....

The 38 Biogon in an SWC has the same angle of view using my Phase One 645
back as a 42mm Lens on 6x6.

Then again, one is square and the other is rectangular, further making this
confusing.......and even more obtuse......

I guess my Engineering background is showing.......

The 645 sensor with a 1.1 to 1 crop 
factor gives me a 42mm biogon
