Tips on locking frame lines M4-2

[.ken]

Hello All. I have an M4-2 with some screw mount lenses with LTM adapter. Unfortunately the frame lines don't indicate what lenses I have so everytime I shoot I have to move the little switch to show the frame lines for the lens I have. Is there anyway to lock this so It takes an extra step away from the process? Thanks in advance for the reply!

Before I got a modified 40mm Rokkor lens that automatically pulls up the 35mm frame lines, I just taped the lever in place. it worked fine and with black tape it was barely noticable. Obviously it isn't too convenient if you are using other focal length lenses.

buy the LTM to M adapters that call up the proper frame lines to the lens you are using.
three different adapters is all you need, quality CV adapters are not too costly to buy.

I didn't even know they have adapters that call up the right frame lines. Good to know. Thanks!
