mingmac Posted October 18, 2009 Share #1 Posted October 18, 2009 Advertisement (gone after registration) I just got an M6 and i have tried to play the lever but i wonder if i can lock it. I just hope that it's possible cos if i change the lens that means the frame line will be changed. Link to post Share on other sites More sharing options...
Advertisement Posted October 18, 2009 Posted October 18, 2009 Hi mingmac, Take a look here Can I lock a frame preselector lever for different lenses?. I'm sure you'll find what you were looking for!
twittle Posted October 18, 2009 Share #2 Posted October 18, 2009 I'm pretty sure they can't be locked, and the framelines are supposed to change when you change lenses. Out of curiosity, why would you not want them to change? Link to post Share on other sites More sharing options...

Congratulations, I have 2 M6's and think they are wonderful, simple and uncluttered discreet camera bodies. If you look at the top of the lens aperture without a lens in place you will see circular wheel. This lines up with the lens cam on different lenses giving you a bright line screen for the lens you have mounted plus another. The cut outs around the lens flanges vary depending on the focul length of the lens causing the circular wheel to deflect for different M lenses. The ability to observe differing bright line frames once a lens is mounted saves the process of having to change lenses to see how the proposed view frames. Enjoy your M6 in good health Link to post Share on other sites More sharing options...

Enjoy your M6 in good health Not simple enough for some! Mingmac, ignore Kenneth's post which is utterly confused. The "circular wheel" and lens cam are part of the rangefinder mechanism and have nothing to do with which brightline frames are displayed in the finder. Those are controlled by a tiny lever in the side of the lens mount near the preview lever; the corresponding bayonet lug has different dimensions on different focal length lenses. There's never been a Leica production model where the preview lever can be locked. Link to post Share on other sites More sharing options...
HarryW Posted October 18, 2009 Share #5 Posted October 18, 2009 Mingmac, I am not sure why you want to do this and as John has said the lever can't be locked, however there is a temporary resolution. Take a small piece of card of the appropriate thickness and jam it behind the preview lever when it shows the frame that you want to see. Very Heath Robinson - I used this when I first mounted a VC 40mm f1.4 which brought up the 50 mm frame line and I wanted the 35 mm frame. I used this for a couple of days before I filed down the claw on the lens mount to bring up the 35 mm frame. Doubt if it's a long term solution though.

mingmac Posted October 19, 2009 Author Share #7 Posted October 19, 2009 Advertisement (gone after registration) What i actually meant was temporarily locked. For instance, I switch from 35mm to 50mm lens so i want to see what i will get on the viewfinder and i know that i can play with the preselector. But what i want is i dont want to spend some time to push the preselector lever until i get the frame line i want for every picture. By default, the frame line is actually for 35mm so i dont want it to spring back to 35mm while im using 50mm, i just want to stop at 50mm frame line during that time. Hope i clarify what i mean.

rob_x2004 Posted October 19, 2009 Share #8 Posted October 19, 2009 Sounds a bit confused to me. If you put the 50mm lens on, the mechanism of the bayonet engages the 50mm frameline and keeps it there. If you put a 90mm lens on the 90 framelines appear and stay there. You only need to toggle the selector to see what you would get "if" you had another lens on. If your camera is reverting back to 35mm frameline for every lens then there is something that needs a service or repair. If you have no lens attached it sits upright, as you say in the 35 frameline position. Link to post Share on other sites More sharing options...

I might be completely misunderstanding what you are saying, and if so I apologise. But it seems possible from what you've said that you believe the selected framelines affect the field of view of the lens. The framelines are only there to show you the field of view of the mounted lens. When you move them using the frame selector lever, it's just showing you what you would get if you changed lenses. If you leave the same lens on the camera and move the selector lever - it will have absolutely no effect on the recorded image. Sorry if I've misunderstood.

earleygallery Posted October 19, 2009 Share #10 Posted October 19, 2009 If you mount an M lens it will bring up the correct frame line. You move the preview lever to simply do that, i.e. 'preview' the other frames without having to physically change the lens - as mentioned above the frames do not affect the image in any way. If you have a screw thread lens you need to match it to the correct LTM/M adapter to get the correct frames - it did occur to me that maybe you are using a screw lens with the wrong adapter and therefore are seeing the wrong frames with your lens on the camera?

redbaron Posted October 20, 2009 Share #11 Posted October 20, 2009 You'll find the instructions for the MP here. It's functionally the same as the M6. Are you using Leica M lenses? Leica Camera AG - Downloads Link to post Share on other sites More sharing options...
garygsandhu Posted October 21, 2009 Share #12 Posted October 21, 2009 From your description, your camera's broke, or your lens is. Cheapest repair: gaffers tape on the selector (I did this when I had the wrong screw mount adapter) Link to post Share on other sites More sharing options...
mingmac Posted October 22, 2009 Author Share #13 Posted October 22, 2009 Hahahaha, my bad. Now i know what the mistake is. I actually dont have 50mm lens yet but i have tried to lock the 50mm frameline while im using 35mm lens. No wonder that it doesn't work. Let me get 50mm lens first then i can let u know if it's broken. THanks guys and sorry for confusion. Link to post Share on other sites More sharing options...
