I have a canon tv zoom v6 17-102mm f2.o lens and a c22525kp pentax 25mm lens for my gh2. The aperture for the tv zoom is very similar to this lens

The fstop barely moves. In the post below the person said he opened it to fix the problem, but I don't know which screwdriveer to use.
I've only seen one post about this problem

Also my 25mm pentax focus and aperture are locked by screws I believe, prob. cuz its a cctv lens. I have no idea what screwdriver to use for that either.

help me please. I really want to play with these lenses
 
Some photos of the actual screw wouldn't hurt. The only ones I was able to see in any of those photos looked like an allen (hex) key to me. If you don't know what you're doing just take it to a camera shop for a service. They'll fix the problem and give it a clean and lube as well.
 
okay, whenever i find my tape measure I'll upload a pic. And where I live there's only one shop within 10-20miles, and their hours are short. I didn't think about the clan and lube, so I'll give them a call in the future. But for right now buying the screwdriver may be cheaper than driving out there.
 
Note there are smaller screws than those covered by a Jeweler's kit, but I doubt that will be an issue with your lenses. If there are then appropriate screwdrivers can be ordered via Amazon.
