I kind of though shutter MTBF was rated at about 50K cycles on amateur cameras and 100-150K cycles on serious pro cameras. Of course MTBF (mean time before failure) like most statistics has no meaning when applied to an individual camera. Nor does it say anything about when the shutter will wear out as that is controlled a lot by how often the shutter is serviced. I would guess a properly maintained shutter would have a life (worn beyond repair) of better than one million cycles, and a lot less if not serviced at all.

I am more worried about Camera Life.
I have shot 5000 shots in the 47 days, I have owned the *ist D. So,
I'm
keeping up my "100 shots a day" rate in average. I sometimes wonder how
long
the camera will keep up :-)

Wow. That might get me to break my lithium habit. Very good.
Thanks to you and Mark.

I did used the LCD at the end of the day to edit the obvious out.


Some

I am very happy with that battery performance - Thank you Mark

Subject: *-ist D and NiMH battery life
I picked up a *ist D last weekend, and am unsure of the battery


life

for
NiMH batteries.  The store I bought it from sold me a 4 pack of
Quantaray 2300mAh NiMH batteries and according to the user manual

for

the camera I'm supposed to get a few hundred shots out of them.  I
don't
have the extra battery pack option, and I'm lucky if I get 30


shots.

The Panasonic lithium CR-V3 batteries that came with it are still

ok.

So, I'm wondering if I either have defective batteries, a defective
charger (I have a sony NiMH/NiCd charger that does up to 4 AA or 2

AAA

batteries at a time, and during a charge the batteries get quite


warm

but not hot), if I'm reading the manual incorrectly or if the user
manual is just wrong.
When the batteries start to die, the battery indicator still shows

full charge, but the camera sounds like it raises and lowers the
mirror
a couple times like it was taking two shots at the same time, and


then

locks solid. None of the buttons work, and it won't turn off. I


have

to take the batteries out to reset the camera.

Neil.
