Hey, Mark Adam called it 1.6 in another post :)
I'm using the old Pentax lenses on that dark side camera you saw me with at GFM.... re the 100 - it allows me to be farther away from whatever I'm shooting. What I'd like to have now is adaptors for each of the lenses I have so I don't have so many pieces to play with when I swap lenses. Anyway - I'm enjoying the combos - sounds like the exact proportion is affected by which particular DSLR I'm using. ann Mark Cassino wrote: >Assuming you are using a Pentax DSLR - the focal >length compared to a 35mm camera is 1.5x greater.
