No beeps for me: M6TTL,VisoflexIII in silent mode and Noflexar 400 with Tex extender: 800 mm in blessed silence! My Canon 100-400 can be bought at ffordes....

I can't really believe that they'd decide to use such a cloth mechanism instead of metal if they didn't see an advantage. After all, that's why they can't go any higher than a certain shutter speed.
Kim Coxon said:I have to say, I am not convinced with the cloth is quieter than metal argument. On both my Canon VI-ls (one sold and the other for sale) the shutter is quieter than the Leicas I have had. This includes M2, M3, M4 and M6. Now the Canon P I had was much noisier. Maybe this had something to do with the fact that the P was a budget model of the VI series.
Maybe Leica didn't like a metal shutter because it would show wrinkles and that wouldn't be Leica like. Besides, most Leicas don't get used that much so there is less chance of burning a hole in the curtain. 😀 😀 😀 😀

Harley Davidson motorcycles have a unique sound. People think they are designed to be loud. I have seen many ego-compensators riding Harleys which have clearly been modified to be even louder.memphis said:Frank:

The harley people would think us crazy for saying that quiet = quality
Powdered titanium catches fire at over 600 °C if I remember correctly. Since ignition temperatures are a function of material shape, a sheet of titanium is unlikely to be set on fire just by sunlight through a lens, and if you've got this kind of heat in your camera a cloth curtain definitely wouldn't "just smoulder". As for the magnesium body, since it is a very good heat conductor, a block is much more difficult to set on fire than the material in powdered form.jaapv said:Not true, Kim, thin titanium sheet burns a heck of a lot better than rubberized cloth, that just smoulders.If you think about it, it might ignite the magnesium body
Cloth has been used for focal plane shutters since the 19th century. It was simply the established material for the job.Crasis said:From a different side, wouldn't the use of rubberized silk or whatever, be a deliberate design decision?

Indeed... even the "cheap" makes and models of cars have engineered sounds. Generally they attempt to make them sound "richer" and "better constructed" as well as maintaining distinctive acoustic qualities. This helps blind drivers identify the type of car they are driving. Acoustic engineering is obviously "over-engineering" in a well-made car but in the cheaper brands it is a concerted attempt to imply adequate-engineering to potential customers. 😀jaapv said:Sound is an extremely important marketing aspect. Car manufacturers have special sound labs and spend many millions optimizing sound performance, down to the clikc of the switches. It does sell cars. It is deliberate that BMW, Mercedes and Jaguar for instance each have their own sound signature.
So it's true 😕 ... street photographers generally take pictures of peoples backs 🙂Sylvaticus said:So as not to make the birds fly off, not to make the animals run away, not to make the people turn round....
You melted down an AEROPLANE when at school???😱 😱 😱Sparrow said:The Lockheed SR - 71 Blackbird is made from titanium,interestingly, when I was at school it melted at 1700°c
