Helps you 'see' what coverage different lenses' focal length can offer to a full frame user (select 35mm film) and a crop sensor body user (select Digital):

To explore different focal lengths, do not select any particular lens. To see a particular lens' coverage (Tamron only, obviously), select the lens from the list on the right.
Add: Just to be fair, here are the converters for some other brands as well:

Couldn't find Sony, Olympus or Pentax.
CHEERS!
P.S. Just for sharing. This is NOT a product or brand endorsement of ANY sort!
