Having shot almost 60,000 on my two bodies (DS and DL) in the past year and three months, 100,000 is not so unreasonable. Thankfully, you don't have to process (nor pay for) every picture you take.

I use my camera every day and have racked up 7,165 shots since August 28th (4 months) on my K100.

I'm hoping that 100,000 figure is REALLY a conservative estimate.
At this rate, it will still last you 4.7 years before it reaches 100k.

I'd say I shoot almost 20K pictures a year shooting Models. +/_ 300 images a shoot, 70 or so Model shoots a year. 20K is 5 years of shooting. In 3 years 10 megapixels is going to be unacceptable resolution. I got the Optio 555 three years ago. So you can still unload the camera at that time and the new owner will still have some use left in the camera.

Kinetics and Thermodynamics

The OP prompted me to check how many frames I shot with my DS2 since I got it last Christmas (2005): 6100. At that yearly rate with my new K10D, the shutter won't wear out for over 16 years.

The Three Laws of Thermodynamics dictate that the shutter will ultimately fail, but kinetics indicate it will take quite some time. At my age, I'm more interested in kinetics than thermodynamics.

What are the difference between these two terms? kinetic refers to movement of particles and thermodynamics to do with temperature induced interaction?

Shutter failed because too heated?

Excuse my ignorance. Just want to learn a little each day I pass by...


Thanks

60 frames every day, 7 days a week? You are professional? if not, what are you doing with all those pictures? what kind of pictures do you take?

I can shoot sometimes 100-150 frames one day in an icehockey game, but games are once a week and many times I take only 30-50 frames. I am lazy and do not want go thru huge mass of rubbish to find good ones and delete others.

If I go out with my camera for walking or some specific place for landscapes, several hours catch can be maximum 30-50 frames, no more, usually lot less, sometimes none. I have to look around, think and again think, then take several frames and then perhaps walk and look around.....

From all those frames I do not save permanently more than 30-40%, from 150 icehockey pictures only 50-60 are saved. Purpose of all this is not to fill my harddisk with data, but make pictures. Even very few of those saved pictures are good ones, maybe 1 out of 300, maybe less.

Kinetics: rounds of use?, 100 000?

thermodynamics: slow destruction of system towards chaos without maintenance? slow destruction of system with time even without the use of it?

There are reports of ist Ds and DSs with over 200,000 clicks on the shutter, and still going strong.

I would not worry to much about the Pentax shutter life cycle rating.

In a broad sense, thermodynamics dictate the ultimate disposition of a system in the physical universe; kinetics dictate how fast it will get there.

About the three laws, some wag once said that they can be reduced to the following: "You can't win, You can't draw and You can't leave the game."

Anyway, I'm an organic rather than physical chemist - I hated P-Chem as an undergrad, but I still have to grapple with thermo and kinetics in my daily job.

Canon Rebels were rated 50,000 releases.
I thought the 350d and 400d were only rated for 10 000 clicks.

100 000 clicks is not that bad a rating when you think about it. As long as the shutter doesnt fail early like it has on many a canon 1 series

The camera is tested for 100,000 shutter releases. It's not like shot number 100,001 will suddenly fail!

I have a couple of MX cameras that might have more shots on them. It's just that for advertising and such, they need a number that they can physically test.

The K10Dís shutter unit is designed to withstand nearly 100,000 releases, while assuring high-precision operation over the entire shutter-speed range ó up to a top speed of 1/4000 second.

From: Steve's Digicams - Breaking News - Pentax 09/13/06 Press Release
here are some shutter life comparisions

Canon EOS 5D professional camera.....100,000

Canon EOS 30D 100,000

Nikon DX2 pro camera 200,000

Nikon D70 50,000

If these are even close to being accurate, for the price of the k10 ... I think you can buy a lot of new shutters with the difference in the price of the Nikon Dx2
The canon cameras are higher priced for the same shutter life

cheers
