Hi all,
I have a K-7 that I adore. I purchased it new in February 2010, and it has been an absolute delight to use. I've been experiencing something troubling with the camera recently, however.
Over the last month or so, I've noticed that the camera seems like it's writing to the SD card more slowly. I used to be able to shoot a burst of ~ 3-7 shots, hit the play button, and almost immediately see the last picture I took. Now, the camera takes much longer in order to display my shots; the little orange light blinks for a few seconds before showing me my pictures. It feels like there's a slowdown in writing to the SD card, or the camera's on-board cache got smaller.
I shoot DNG without JPG previews. I've noticed this problem with several fast SD cards (Sandisk Extreme IIIs or better). I always format my cards in-camera after I download my shots into Lightroom.
Image quality hasn't changed; it's still wonderful!
This feels like it'd be darn near impossible for a tech to diagnose, let alone fix. I also wonder whether it'd be cost efficient to fix.
Any ideas? The shutter has roughly 30,000 actuations, and the camera has been a faithful, rugged companion while shooting wildlife in the Mojave desert and brides at weddings. I didn't think it was possible for a modern camera to develop patina, but the "battle damage" on my K-7's magnesium-steel body tickles me.
