645D...shutter life?

Anyone have an idea on the shutter life for a 645D?

What about replacement time when it goes out? How much to fix!!

Thanks!

I think it's rated for 50,000 actuations, which is less than most other DSLR's. Not sure how much the replacement costs. I don't know anyone who's had to have it done due to 'wearing out'...that's a lot of shooting!

Guess it has the big mirror flapping up and down that does not help. I can live with 50K, but was hoping it was like the reg pk dslr's.

You must shoot a lot more than I do. In two years I only put 6000 actuations on my 5D mark II. But I'm a landscape shooter, and not shooting bursts constantly, though I do bracket a lot.

Well it is still a good deal at 50,000.

With film, 50,000 shots cost about $18,300

...plus all the crap we pour down out drains for film!

50,000 does seem low but I guess I can understand it being a technical limitation with everything being bigger on the 645D.

I'm at a little over 16,000 in around one year's use on my K-5 and I don't think I use my camera nearly enough. That hasn't been racked up using bursts either as I very rarely shoot with bursts. With the 100,000 shutter life on the K-5 I should have no problem getting six years of good service from the camera. A fair deal, if you ask me. The Nikon D4 has an insane 400,000 rated shutter life! There are a couple of threads on here with people sharing their shutter counts, plenty have far more than I do.

EDIT: I should add that I have a low keeper rate quite a bit below 10%. I only wish I had portfolio worthy shots numbering in the hundreds, let alone in the thousands!

The 645D is meant for a different type of shooting style. Especially with that 1 second of delay per shot (give or take).

Yes Jin. Slower pace more or less.

In any case, if you can get it fixed up with a new shutter for a few grand it is no big deal. We are all talking like the thing has to be trashed. Just depends on repair costs.

You don't spray and pray with MFD, 50,000 is plenty.

My highest year was 13,000 shots, and I average about 8,000ish per year. If you go out shooting a lot, it adds up, even at 100-250 at a time.

The 50 000 number is not when the shutter disintegrate but the number where the manufacturer guarantee that the shutter is within specification without adjustment or service....
This is a very conservative estimate....

That's what I also read about the 645D. There should only be a recalibration of the shutter every 50.000 shots, to guarantee the same quality.

The shutter in my 645D failed on me last month, while I was in the middle of a shoot in Arizona. I didn't take specific note of the shutter actuations before sending it back for repair once I returned to Calgary, but I'm pretty sure it was somewhere between 50K - 60K. I had one of the first 645D bodies in Canada (purchased Nov. 2010) and as such it qualified for a special 2 year factory warranty offer from Pentax Canada. The camera has to go back to Japan for the repair, but they are honoring the warranty claim (after I had to prove to them I actually qualified fro the 2 year warranty based on the original purchase terms). Otherwise the quoted price to repair was just a bit under $1000 CDN.

I bracket extensively, plus increasingly use the 645D for situations where the number of "experimental" shots is high, compared to what I actually keep. (E.g. street shooting, some wildlife.) 50K shutter actuations is not much for me. Heck, I did 3 weeks in Iceland and shot something like 7500 frames on that trip alone. Hopefully mine failed merely because of bad luck or something, and not because the shutter mechanism actually wears out at 50K. Otherwise I might be replacing it a few more times... it will be off warranty after this.
