canon135 fd 2.0

I have a cannon T-90 when Im shooting with my 135(2.0)fd sometimes the shutter locks and it seems to ware my batteries.and then the arrow that points to the shooting modes flashes, to unlock it, I usaully have to move the aperture ring,then it works fine for a while.anyone have an idea what the problen can be.

No idea.

Is this when the lens is set to A?

I think this has been described either in the service manual (or in

another article which I had and sold). Maybe someone with enough

literature could help?

I bought Vessa-Pekka's manuals from him. Here's the scoop:

"Camera switches to error condition (EEE, no operation) or switches

from high speed operation to low speed with the drive mode LCD arrow

flashing. If the batteries are OK, the problem is normally caused by

the lens; if the diaphragm operating ring isn't moving smoothly, it

overloads the camera mechanism. Check to see if the the customer is

using an off-brand lens (usually a tele) with a heavy diaphragm

action. Reset the camera by removing and reinstalling the battery.

The problem may also be caused by a defective shutter block"

One of my lenses actually caused 'help' to be displayed. Exchanging

the lens solved the problem (a new lens that was sitting around for a

while). I think the 135 needs to have the diaphragm mechanism

cleaned and/or adjusted. It's a simple job as long as nothing is

damaged.
