Slow to view images

So I finally joined the club and so far I'm loving it.
There is one thing I find a bit odd though, and that is how long it takes to view my images sometimes. The 1 sec preview is a bit slow also, compared to my k-x. But whats really slow sometimes is just viewing my pictures in playback mode. Sometimes when I press the button it appears almost instant, but sometimes I get a loading bar and hourglass and it takes a looong time! And I haven't been able to determine why it's inconsistent like that? On my k-x they would show up pretty fast.

For the record, I have NO corrections enabled, except for the default noise reduction settings.

Sounds like it's taking a while to read your card?

Take a load of pics in the lowest quality setting (2m JPG, 1 star on the k-7) and see if it's quicker.

Bigger files may mean you either have to wait (that's what I do) or get a faster card.

Hm yes it seems it will playback a burst of jpg instantly, but a burst of raw is really slow. But once I have viewed them once, it's fast the second time. What causes this? And if it's my card that's slow (it's a class 10 trancend, cheap but should be ok) which one should I get for optimal performance?

Disable shadow/highlight correction and slow shutter speed NR and the review time should go back to normal

Best SD cards are the SanDisk Extreme III cards that are Class 10 (30Mb/sec).
However, even with these cards, the card speed exceeds that of the K-5's write speed, causing that delay in reviewing images right after you've taken a series of burst shots. Once they're dumped onto the card, playback will be instantaneous. So the delay you're concerned about is more a camera limitation, but should also be evident on every other camera you've used.

I guess it's the huge file size and much larger buffer that's making it feel slower then my k-x. It's moving a lot more data for sure. A bit disappointing still. I will try with a sanDisk card and see if it improves.
