Maybe worth a try... put your batteries back in and connect the charger, then try turning the screwdriver on the drive screw again with mains power going to the camera. In the past when shooting in the studio and my batteries have gone dead, I've connected the charger and effectively used it as a mains adaptor to continue shooting while the batteries are charging. Be really careful with the screwdriver so close to tour rear element, I would always use a slightly larger one to give me more purchase and reduce slip on the screw. For what it's worth in my opinion I don't see that changing from CF to C lens would have anything to do with your situation, I have a variety of lenses and tubes and providing I wind before changing I never have an issue. Hope this helps, Craig
Thanks buzzski for your interest in solving my EL/M problem.
I have managed with one of the many custom screw release tools available to remove the lens from the camera body.
I have recharged the batteries, but the camera does not complete the cocking cycle when moving the L-O-T switch from L to O as per the Hasselblad Instruction books.
I now suspect that I may have a blown fuse, though I cannot tell visually if it is really bad. I suppose there is some kind of test I could rig up to find out for sure.
I am in the process of mail ordering several of the Hasselblad (custom) fuses since nobody locally stocks them (or has even heard of a fuse with the specs used in the Hassy EL series cameras). Whether this is the actual problem or not I suppose it will be good to have extras on hand since they are not readily available. I have already placed an order for 2 new Nickel Metal Hydride replacement batteries.
I wish there still was a Hasselblad Authorized Repair dealer in town. Or even a Professional Camera dealer. Sign of the times I guess.
In the meantime, I have reviewed all my manuals, much online material, and even Ernst Wildi's Hasselblad book. There is a definite lack of
practical operating advice for the EL series of cameras even though it was in production from 1964-2006!
One conclusion that I have reached in regard to Hasselblad EL series cameras is:
Do not try operating ANY EL camera body series function whatsoever, without fresh battery power, whenever a lens is attached to the camera. This advice should supercede the common(?) knowledge that one should just never change lenses on a EL series without battery power.
I am glad to I am gradually upgrading to a newer Mamiya AFD series camera system, which is a least 30 years ahead in camera technology.
