File sizes are subject and ISO related, it can vary from 10mb to 20mb or even more. But a 32gb card should be enough for you to go for a long trip.

Your camera tells how may shots left in memory in either RAW or JPG mode

Hmmm not a long trip but a short job. I would normally take about 300 images ( lots of bracketing ) on an 8 gb card.....not much space left over. The Km has smaller files than the K5.......and I don't want to run out of card space on a job lol
I shoot mostly at iso 100 in dng......
cheers

With a fresh 16GB card in the K5, shooting RAW (DNG) plus JPG, the display shows about 331 shots. All things being equal, 32GB = 660+. If you shoot in RAW only, perhaps 20% more.

My 32GB card reads as 922 shots with DNG RAW only. In practice, you will get more than that because the 922 figure is derived from max file size, while real file sizes (at lower ISOs) can be considerably lower. It also works out to be roughly the same number of shots you get on a single charge of the battery (as long as you don't use lots of built in flash or SDM/DC), which is convenient.

According to Pentax Japan's specification sheet, the number of images is as follows. Obviously this is a rough guide as image file sizes will vary.

Ei kai enään nykypäivänä tarvitse miettiä mitään taulukoita.
Vaan ostaa suurimman ja nopeimman kortin mitä on tarjolla.
joku 32 - 64 / 10 , siihen ottaa RAW kuvina otokset.
Ei JPEG kuva ole mikään " nekatiivi kuva " jos haluaa kuvasta muokata joskus kunnon kuvia.
Se mahdollisuus on armotta mennyt. Kuva voi olla niin ainutkertainen ja tärkeä, tilannetta ei
saa ikinä takaisin. Ikinä ei tiedä etukäteen mikä on tällainen kuva.
Itse en ota ikinä muita kun RAW kuvia. Jos tässä täytyy nuukailla kannattaa ostaa joku halpa
pocket kamera.

If I'm shooting something important, I'll use at least two cards to be sure that a single card/reader/port/cable failure will not wipe out the entire shoot. I'm not speaking of a paid shoot as I don't do that. (No one is foolish enough to pay me. )

I understand that professionals take the same approach, particularly event photographers who cannot arrange to do the job over if needed.

I cannot imagine trusting 500+ images to a single card. I usually swap cards at a convenient point over 100 images but again, that's without bracketing.

Some may differ. I'd like to hear their views. I may have to break down and invest in a few 16GB fast cards. Ouch!

It can hold some 1350 DNG RAW pictures on a card like that.

Well after my next purchase I only have 32GB cards. I would like to have two cardslots on the next camera just for security.

I've shot on 16GB cards on the K10D for 3-4 years and have never lost a card. I have had individual corrupted images (usually because the K10D crashed whilst writing the image - which it seems to do from time to time) - usually I know when I have a corrupted image and retake the shot.

16GB is a nice size on the K10D because it allows nearly 1000 shots in Raw mode. I rarely shoot more than 1000 shots a day.

For backup, I carry one of those portable card reader coupled with hard drive to allow me to copy card contents onto hard disk. My unit is an old Hyperdrive Colorspace but there are similar units - some even supporting fast transfer speeds.

On the K-5, 16GB allows less than 500 shots and I have run out of card space in the middle of shooting several times. So 32GB makes a lot of sense.

Modern SD cards are quite sophisticated inside, and they have things like wear levelling, bad block remapping etc. built in, so I think they are relatively safe to use (or at least the ones I have bought have had no issues).
