Hi there,
I'm trying to separate this lens from the board. When I unscrew the 5 screws shown in the picture, nothing appears to be obvious about how I can remove the lens from the board. It is still very securely attached to the board.
Any hints for me?
Tx!!!!
I've just removed a similar lens in a Compound shutter, I just unscrewed the shutter from the board after removing the cells, needed a fair bit of muscle though. edit - mine had the screws on the lens side so obviously a different setup to yours
Your flange is probably just stuck to the black paint on the lens board.
Unscrew your lens elements and shutter from the lens board and put them some place safe. Take a screwdriver and remove the screws that are holding the flange to the lens board. With your fingers try to remove the flange. The paint may be holding it or it may have been hand screwed into the board (tight hole). It depends upon how the flange is made.
If none of the flange is inside the board you can then place a towel under the lens board (to prevent damage) and clamp it to a table. Take your screw driver and place the blade against the lip on the flange. Tap it with a hammer to loosen the flange from the board. If this doesn't work then try to pry the flange away from the board with your screwdriver. Just be careful to not damage the board.
The shutter is threaded into the flange from which you removed the screws, the flange is working as a retainer on the back of the board. I would put the screws back in the board, unscrew the shutter from the flange, then remove the screws again from the flange. As mentioned above, the black paint may be holding the flange on the board.
You may be able to unscrew the shutter without replacing the screws, but the flange may spin along with the shutter if you don't.

Clockwise to tighten, counter clockwise to loosen.
Or, righty-tighty, lefty-loosy.
Yeah, we always told the apprentices that!
I have another idea. If you get everything apart and the flange is still stuck then put the screws back in. Hand tighten the shutter to the flange tight. Take the screws back out and holding the shutter in one hand and the lens board in another turn the shutter counter clockwise to "break" the flange loose from the board. Of course if successful you now have the shutter and flange spinning freely on the board. Turn it all until the flange holes line up with the board screw holes. Reinstall the screws and remove the shutter. When you remove the screw holes the flange should fall off.
Great, I'm going to try these things tonight. Question - I'm actually removing this lens in order to sell. Do you think the lens should stay with the camera or go with the lens/shutter combo?
