I sold my 80 and bought a 60.
On trips I found out that the 80 was often to long for me when i stood at the back of the wall.
With the 60 I force myself to crop the scene to the most important part.
besides that i use the 120 macro and the 250 and have a vivitar 2x converter which does a pretty good job on the 250 i found out. I did not expect this quality from it. They are a bargain around 100 dollar.
But it's just what you are going to do with it....
For landscape (wide) I use my 4x5, not the hassy.
