Many speculations have been flying around in the internet regarding how many count Canon DSLR camera shutter can last. Instead of just guessing around, I have decided to refer to Canon Japan themselves. Yes, need words from Canon Japan themselves in black and white (or colour) instead of just verbal talk.
Here’s what I found in Canon official camera brochures:
Canon EOS 1Ds Mark III - 300k shutter duration test

Canon EOS 1Ds Mark III - Did not mention in the brochure, other than just “Accurate Highly Durable Shutter”. However the shutter picture is same as the 1Ds Mark III picture, so I would guess it to have the same 300k shutter duration test as in 1Ds Mark III.

Canon EOS 5D - 100k shutter duration test

Canon EOS 40D - 100k shutter duration test

Canon EOS 450D - No info in the brochure.
what about nikon? my d50 shutter count is quite high oredi.
Hi Wyejon,
