Manfrotto 521 vs 521PRO
 

Does anyone have experience with both the 521 and 521PRO lanc zoom controllers for sony cameras? I currrently have the 521 and want to find out what the difference is with the pro version.

These links should help:

The basic difference is that with the 521PRO you can control the zoom function as you wish.
