arthury Posted February 22, 2014 Share #1 Posted February 22, 2014 Advertisement (gone after registration) Most other manufacturers (like Nikon) do rate their shutters for their pro bodies, how many actuations did Leica rate the shutter of the M240 at?

Advertisement Posted February 22, 2014 Posted February 22, 2014 Hi arthury, Take a look here Shutter rating of the M240. I'm sure you'll find what you were looking for!
Voigt Posted February 22, 2014 Share #2 Posted February 22, 2014 I don't believe Leica has rated their shutter. But you'll probably find several OPINIONS as to how long they're expected to last. Link to post Share on other sites More sharing options...
lenicolas Posted February 22, 2014 Share #3 Posted February 22, 2014 Yeah, Leica doesn't do that. And in the new M they've made it impossible to know the number of actuations anyway... My theory is that they made this to support the used prices of their equipment. Link to post Share on other sites More sharing options...
Overgaard Posted February 23, 2014 Share #4 Posted February 23, 2014 It was said to be 100,000 for the M9 and M9-P. Mine have shot 60,000 and 180,000 and had absolutely no problems. I guess they just have to give a number, and they would give one as reasonable low as possible so as to not have to guarantee forever but for reasonable use.

250swb Posted February 25, 2014 Share #6 Posted February 25, 2014 My theory is that they made this to support the used prices of their equipment. It's the same as the way Rolls Royce don't publish how much horse power their cars produce, it is described as 'sufficient' As Leica don't make the shutter but import it from Copal I'd assume it would be up to Copal's (and therefore similar to Nikon's) pro specification, but not providing a guide is remiss when so many people look at buying a Leica as a long term deal (until the next model is released at least).

lenicolas Posted February 25, 2014 Share #7 Posted February 25, 2014 Advertisement (gone after registration) What I meant was this : Cheap used cameras means it's (a little) harder for Leica to sell new ones. There always seems to be people who sell their Ms with less than 3000-5000 actuations no matter how old the camera. Next to these, a guy selling a normally used M with 15000 clicks has to offer a discount to stay competitive. > used Ms with a reasonable number of actuations (15000-20000) become way too affordable to justify buying a new one. (for people who reason like that. Of course there is people who always buy new whatever the discount on used stuff) If I was Leica, I would have stopped providing actuation counts for that reason. But your rolls Royce comparison sounds just as likely, and I agree that there's no real reason for a shutter rating (on any pro camera for that matter).

arthury Posted February 25, 2014 Author Share #8 Posted February 25, 2014 The reason for my asking was due to some occasional rumbles about M8 shutters breaking. I did not keep my M8 long enough to see any of these complaints and my current M9 has been fine for years.Wasn't the M8 Copal shutters, too? Link to post Share on other sites More sharing options...
lenicolas Posted February 26, 2014 Share #9 Posted February 26, 2014 I believe it's been established that the original M8 shutter had a design flaw. That's why the M8.2 came out with a different shutter that only reached 1/4000s (against the original M8's 1/8000s) Link to post Share on other sites More sharing options...
jaapv Posted February 26, 2014 Share #10 Posted February 26, 2014 You believe wrongly. The only reason the M8.2 was fitted with the same shutter running at half-speed was because users found the original shutter too noisy. As a matter of fact, as I recall it, the catastrophic shutter failures, few as they are, mostly ocurred on the slower shutter. Basically the shutters of M8, M8.2 and M9 are identical with exception of the running speed. Link to post Share on other sites More sharing options...

That is in contradiction with Leica's product manager saying, when asked about a cheaper entry model : "We regard the used cameras as the entry model to the M system..."

jaapv Posted February 26, 2014 Share #15 Posted February 26, 2014 Exactly the same as the M8.2 and M9 - mostly unknown cause. Without firm data I would say that catastrophic mechanical failure would be most likely caused by a piece of grit between the shutter blades - there is no protective mirror in front- and the most common shutter error would be stuck teflon “fingers”.

Blowing the sensor with a Giotto rubber bulb only drives dust/grit off the sensor but they may still fall into the back and return at the most opportune moment to lodge themselves on the shutter. Given that this is the most likely cause, what's the best way to prevent this? Anyone? Link to post Share on other sites More sharing options...

dkCambridgeshire Posted March 5, 2014 Share #18 Posted March 5, 2014 The M 240 has a 'dual' type shutter and when used in live view, multi field metering or spot metering modes, the shutter has an "open - close / open - close " action … as distinct from normal single "open - close" action when in regular optical / rangefinder mode. Thus if used in e.g. spot metering mode all the time the shutter actuations are doubled. dunk Link to post Share on other sites More sharing options...
