Guest Walt Posted December 5, 2007 Share #21 Posted December 5, 2007 Advertisement (gone after registration) Walt, the wear I was referring to was that on the sides of the screw retaining slot in your example. I do not see the corresponding wear on mine or that of the screw and that's after 10000 exposures. Seems clear there's too much variance from one camera to another. I'm certainly going to try polishing the parts and using a lubricant as you have described. Mark- Just a few points I left out of my last post. Of course, the advantage of taking this apart and using a grease is that it goes where it does the most good and it stays there. The temperature stability (viscosity) of the grease is important--you don't want it getting hot and running down on the switch or getting cold and dampening the action of the release. On the amount of grease: in my lubrication, a pea-sized glob of grease would lubricate several hundred cameras. I mixed a bit of flourescing dye into the grease and after two weeks of use, I have seen no migration of the grease onto the top of the switch. In the top lubrication I did with oil the first time around, this seemed to have helped for two reasons. It migrated down between the cable release plunger and inside of the shutter tube and out through the screw threads, where it provided some lubrication in this problem area. It is also a help to have lubrication between the cable release plunger and inside of the shutter button tube because this allows the two parts to move more freely against each other. Thus the load from the shutter switch (and detents) into the plunger is not as easily transmitted into binding the shutter release tube against the finger rest tube, i.e. the c.r. plunger acts as a buffer. The disassembly and grease is hugely more effective though. In their current condition, I wouldn't give these releases a thought--they are just fine.

john_newell Posted August 1, 2009 Share #22 Posted August 1, 2009 Heretical reply alert - Sitting on the couch, putting the camera through its paces, I notice the rough travel and it annoys me. However, in real life, shooting pictures, I have never noticed and it doesn't bother me at all. Link to post Share on other sites More sharing options...
larry Posted August 1, 2009 Share #23 Posted August 1, 2009 Walt, Thanks for your objective, analytical approach to explaining and solving this problem. It seems that many M8 users have had a love/hate relationship with the camera for the last 2-1/2 years. Its rough release and the relatively loud shutter are almost universally criticized as being very uncharacteristic of Leica cameras. It's important to keep the spotlight on these problems so the company will be more attentive to the fine details in future iterations. Larry Link to post Share on other sites More sharing options...
jaques Posted February 24, 2010 Share #24 Posted February 24, 2010 Following on from the last post: we now have the M9 on the market- I have one- but have never used an M8. Does anyone familiar with both cameras have an opinion as to whether Leica has improved the shutter button and rectified these problems on the M9 release? For what its worth the action on mine feels very smooth but I am relatively new to leica and could be a philistine when it comes to my idea of leica 'smoothness'.

marknorton Posted February 24, 2010 Share #25 Posted February 24, 2010 The M9 appears to be the same as late production M8/8.2. Leica seem to have refined the adjustment to avoid the distinct grittiness which plagued the earliest cameras. They may also have upgraded the specification of the parts along the lines Walt suggested. It's a significant improvement though not yet in the film M league.

cbretteville Posted February 24, 2010 Share #26 Posted February 24, 2010 Wonder if this applies to the M8u too. Have to try mine side-by-side with an M8.2 and M9. Carl Link to post Share on other sites More sharing options...
marknorton Posted February 24, 2010 Share #27 Posted February 24, 2010 Advertisement (gone after registration) Yes, it does here. 2 M8u's and an M9 side by side, all feel the same. Link to post Share on other sites More sharing options...
250swb Posted February 24, 2010 Share #28 Posted February 24, 2010 For what its worth the action on mine feels very smooth but I am relatively new to leica and could be a philistine when it comes to my idea of leica 'smoothness'. When I got my M9 I felt the shutter release had a very gritty feel to it, to the extent it interfered with the first pressure on the button to lock exposure. But, after a few hundred exposures it is now very slick and smooth, so I guess the parts have settled down together. Steve Link to post Share on other sites More sharing options...
cbretteville Posted February 24, 2010 Share #29 Posted February 24, 2010 Yes, it does here. 2 M8u's and an M9 side by side, all feel the same. Cool, thanks Mark. Carl Link to post Share on other sites More sharing options...
TacTZilla Posted February 25, 2010 Share #30 Posted February 25, 2010 Would anyone in the UK who has one, be kind enough to lend me a flexiclamp for a short while so I can do this mod? I'd be more that happy to cover shipping both ways. Cheers Bob Link to post Share on other sites More sharing options...
