hi all,

just got a used C100 mark II.

i'm trying adjust iris...the dial on handle doesn't do anything. and when i go into menu: IRIS-MODE--it's greyed out and i get message that says 'this function not compatible with this lens'.

i'm using an canon EF 24-105/f4...which should be compatible, right?

does anybody have any advice?

thanks so much.

Advice? Well, the manual clearly states which lenses will function with Auto Continuous Iris... L glass is excluded as is all 3rd party glass (I haven't checked the list in about a year so you may want to look into this). Button 12 will be used or you can freely assign the function to most any other button. Push Auto Iris will will function with EF-S and L lens and most 3rd party lenses (lets say as I don't know completely which do and which don't). STM lens take advantage of all AF and Iris modes.

I forgot your first point. The dial should change the F-Stop of the lens. Are you sure the handle electrical connector is fully engaged in the camera's socket?

Yep, your plug from the handgrip is probably either loose, corroded or messed up. Can you trigger record from the handgrip/use the grip joystick too or no?

Even so, it is possible to have some functionality but not all with an unseated connector.

Disappointingly, I experience this even with my brand spanking new C200. I have had it so iris works but record doesn't, record works and joystick doesn't, etc. I thought that grip cable issues with the stupid handgrip relocaters with my C100/300 were going to be a thing of the past but they're not. My C200 has lost partial connection with the body several times, even when using the plastic seating collar with the grip that comes with the C200. The grip has worked, then stopped working, then I reseat the plug, even with the grip in place and then all of sudden it begins working for no reason, I just nudge the connection with my thumb or forefinger while it is plugged in. Stupid.

I've also experienced it when using the $80.00 Shape grip extension cable and it's the connection at the C200 body, not the Shape Cable at the handgrip. Not all of the time, just at the worst possible times when I am operating shoulder mounted and just need to QUICKLY iris down during a take. It's amazing to me that this is still an issue with the Canon C cameras, Canon SHOULD have switched to Mini BNC or some other type of locking, positively seated connection for the grip connection years ago instead of a lame slip fit multi-contact connector that frankly kind of sucks.
 
Agreed but as we've seen with any "product improvement", in general, not everything has priority. Unfortunately, this isn't something we as users can remedy with aftermarket equipment. Wooden and ARRI cables yield intermittent results as well. The locking collar is all that comes to my mind as well. A kind of bayonet connector wouldn't work though as the pin layout eats-up too much real estate. I can sympathize with you puredrifting- you always seem to be working a shoot and to have something of this caliber potentially ruin that work is sad.

I have had my share of freak things happen around Canon cameras that never used to happen when I was shooting big, heavy expensive broadcast cameras like BVWD600s, F900s. I don't think I would run into nearly as many issues if I was shooting an Arri Alexa SXT or something just plain better constructed and built. I like Canon cameras but in the big scheme, a $7,500.00 camera isn't going to function as well or be engineered to be as reliable, in general, as a $60,000.00 camera. It's the price we all pay for shooting with amazing spec, cheaply built cameras. No Canon Cinema camera, short of the C700, is really what I would consider pro level constructed with lots of metal parts, over engineering, redundant systems, etc.
