K5 locking up

SenorBeef · 08-02-2012, 08:14 AM

FWIW, I got my camera back from CRIS and this was on the work order:

CHECKED FOR LOCKUP. MEMORY BUFFERING

But no associated fixes, so I guess they didn't find anything. I don't know if this means that they know what the issue is and it was related to buffering, or if they're just writing it out like that because of how I described it.

Have same problem: completely lock up k5/Av/55-300/liveview off/no battery grip/AF.S/ battery level about 90%/ while focusing , twice in a day. Works perfectly with primes. K5 is brand new and I already had sensor replaced and now this

Snr; 4332...

Does it only lock up in Av or other auto modes as well?

I had three lockups during New York Fashion Week shooting major runway shows. Really the most terrible times to have a camera failure, I missed several looks. Three times with a 50-135 f2.8, once with the 200mm f2.8, ISO 400 on one show and ISO 800 on the other, lots of autofocus usage and rapid shooting, 16MP JPEG ***, firmware v 1.13, and I do not use noise reduction.

FWIW, I don't know if they actually did anything to my camera at CRIS, but I haven't had a lockup in over 3000 shots including lots of action shots. I also switched to a Sandisk Extreme memory card, not sure if that's a factor.
