100k exposures?

I read somewhere, I can't remember where, that Pentax guarantees that the K10D will survive 100k exposures. What does this mean? If I have more then 100k exposures, will the guarantee be void?

I kinda thought the 100k sounded alot, before I got the camera, now I realise that if I keep up this speed, I will reach 100k rather quickly, atleast before the ordinary guarantee runs out.

Thought it was 150k. I think if you reach that number while your warranty is still valid they will replace your shutter (wrong?). If not, the warranty for the rest of the camera still holds up :]

Not exactly. Pentax "rated" the shutter at 100,000 cycles. The guarantee is time related only.

This is meantime to failure for the part. All the moving/electrical parts will have some rating by the maker of the part (this is probably not Pentax). The shutter release button may have some number like 500,000 or a wheel maybe for 1,000,000 turns. For a switch like focus mode that is not used as much it may be something like 20,000. Just because the shutter is rated at 100,000 doesn’t mean that it will work until 100,000 and fail at 100,001. Some may fail at 50,000 or some may fail at 150,000. If Pentax wants a warranty for like one year lets say, they will look at how much everything they think will be used by what they think there average user will use it. They then buy parts that will give some fail rate of what they want (1% or maybe 10%) that they can live with that they will have to pay for. Sometimes all you can get is a part that is way over rated for the needs so they just buy that part because it is cheaper then having a part made rated for less, or if that part fails under warranty it may cost to much to repair so they may have to replace the camera. I think the shutter number is more the latter. The bottom line is if the warranty is for 1 year that is what you get. If some how you shoot 200,000 in 9 months the warranty is for the 1 year not the 100,000 on the shutter.

When I set the warranty was "time rated", I meant that it was for 1 year (USA), 2 years (Canada), 1 year (International), etc. I should have made myself more clear.

Exactly...it's like MTBF (Mean Time Between Failure) like electronics are rated. Check out the database here and you can see that a couple died early, while others are going strong above the rated number...and most are just chugging along at normal rates.
