Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.

I am sorry to hear about the problem. I would like to help solve it.

Please tell me first, what lens you are using with the 5DSR camera ?

And, does the problem happen with any other lens (or, do you only have the one lens to use with it) ?

all lens the camera was working fine last week I went through all programs i do not think I changed anything??
Expert:  Russell H. replied 2 months ago.

You could try doing a Factory Settings Reset on the camera body, and see if that alters the case.

By any chance, when you first found that the aperture setting was stuck, were you wearing a woven sweater, or a woolen garment of any kind ? Wool attracts static electricity, and handling electronics while wearing woolens (or sweaters) can cause discharge of static into the device, which may lead to severe problems. It's just a thought to mention.

no noting to do with with clothing i did clear all factory settings... I thought you would know a little more then me .. when i went on line you guys used a canon type logo to draw me in... I will pay the five dollar deposit But I feel scammed for the $26

I don't think you were scammed.

If you have any concerns about billing or charges, please contact


and they will take care of it for you. (I have no power over charges and billing, I just try to advise people on technical matters.)

I think you have done all you can do. There is most likely a problem in the lens assembly. It will probably have to be serviced (or replaced, at your choice - unless a warranty applies to it, in which case warranty servicing should be free of charge).

I'm sorry this case didn't turn out better.

(In case you would like a chance at a second opinion from another camera expert here, at no additional charge, I have Opted Out, opening the case to other Experts.)
