Anybody knows what the shutter life of M8 is?
I wonder how many cycles it can take.

I just want to know.
Isn't the M8 using the same shutter as the Leica R8?

How long will it last?
How many cycles has your M8 done?
A Nikon D40x can roughly take about 30,000.
 
I read somewhere a conservative 100000 cycles. 30000 seems a bit short on any camera. The Canon 10-40 series has 50000, running up to 150000 on the top ones. Anyway, enough to last you for quite a while. It is not an expensive item to replace, the shutter itself costs 183 Euro as a part.
 
I’m not a pro and at my age I’m certain it will out last any amount of shutter activations I could possibly put through it. In fact, I’m such a geek that I’d likely sell my M8 and buy the new offering in a year or two.
Regards,;)
 
the M3 boasted of half a million clicks on your shutter before it needed service, now THOSE were the days! My bet would be half as much as that for the M8 (I am an optimist), but I have another question: how does depth of field influence Leitz lenses when fitted on an M8 with a x1.3 factor? Do the old markings on the barrels of the lenses for DOF mean anything now? I'll be obliged if someone clarified this to me.
Regards.

Argh!

Of course the DOf stays the same! This is basic 101.

Mike, I wouldn't bother. It's such a simple concept that I find it unacceptable for anyone not to be aware of this. Especially for a guy that founded a Nikon Historical society on the internet before Netscape existed- in his own words.

Old spring activated/oil lubriacted cloth shutters are nowhere near tackling 500.000 actuations. - You must show me a link to this claim. I would argue that the spring activated/oil lubricated cloth shutters common in Leicas up until M7 and MP's are good for max 50.000 exposures. At best.

The shutter in the M8 is far better. It is magnetically activated and silicon lubricated. Which is common in most shutters today, like Leica R9, Zeiss Ikon (even) and most digital SLR cameras. These are far better than the old fashioned Leica shutters. My Canon 1Ds II is supposedly good for 250.000 exposures. The new 1Ds III is good for 300.000 exposures. I am sure that Nikon's top models have similar endurance. Remember: Many pro's will activate 50.000 exposures per year.....

Nonsense. Dof is solely related to the enlargement of the subject in the final print, as seen at a defined viewing distance.
Please explain why the DOF of a small sensor camera is far deeper than that of a full-frame camera.

Using the same lens, the DOF isn't deeper! If we're using a 50 summilux on a M8 vs an M6, they'll have the same DOF. All the M8 is doing is cropping that image from the 50mm and giving you only a 1.33x crop.

Now if you're talking about a smaller sensor camera, i.e. point and shoots? Yes they are far deeper because their actual (not 35 mm equivalent) focal lengths are tiny! Take my canon p&s for example. It's a 30-120 35 mm equiv, but the actual focal length is 5.8 mm. 5.8 mm is going to be way deep.

The DOF of a small sensor camera is far deeper than that of a full-frame camera because they are normally equipped with lenses of much shorter focal length.

On the M8 the COC is 0.023 mm as opposed to 0.03 mm on a 24x36 camera, resulting in a deeper DOF. Because the sensor is smaller, one needs to enlarge the image more, changing the DOF. The same is valid for instance for medium format cameras vs. 135 cameras. You can check the figures and results here:
http://www.dofmaster.com/
The reason wide-angle lenses have a deeper DOF than tele lenses is because they enlarge the subject less. DOF is NOT a characteristic of a focal length. That is illustrated by the fact that DOF gets more shallow when you get closer with the same lens, dwindling to practically nil in macro, because the subject gets enlarged more.

Sorry - hyperfocal distance is not the same as depth of DOF - although the two concepts are related....You can't be THAT stupid if you come up with the right answer :D

On M8's manual, p.87
Quote: 'The nominal focal lengths of Leica M lenses are based on the 35mm-format, i.e. on a film format of 24x36mm. In comparison, with its 18x27mm, the sensor in the LEICA M8 is somewhat smaller though by a factor of 0.75. Therefore, when used on the LEICA M8, these lenses have angles of view corresponding to lenses with focal lengths that are longer by a factor of 1.33 (1.33 = reciprocal of 0.75). This
has the respective effects on their perspective, but not on their depth of field, which, with the LEICA M8, can also be read directly off the lens (see the lens instructions for more details).

The bright-line frame in the viewfinder of the LEICA M8 of course always shows the “correct” field of view for this camera, i.e. it takes account of the increased focal length. You can therefore compose your pictures
in the normal way, just as for other cameras in the Leica M series'.

End of quote.


As always, my suggestions for buying any camera, go download the manual, read through it.
Understand it, see whether you like it.

BTW, I have been recently reading Nikon's D3 manual. It 476 pages long to be exact (japanese version that is). Gosh, when is Nikon going to put out a full fram FM3a type digital version?
Simple, smaller, lighter, FX sensor . . . just give me M mode . . . .

GeeZ!

Take a FF picture and cut 1 inch around it. Do you gain DOF? No. Well, this is the same as cropping a sensor while not moving with a camera.

Same as the D2X in camera crop. The DOF simply doesn't change if the photographer doesn't move.

I don't understand the people trying to correct me on this; It is so simple.

You don't mean by this that you can't mount lenses on the D3 that you could on the FMxx, right?
