I agree memory is pretty cheap, but the time factor is still an issue if you shoot a lot.

George,I agree memory is pretty cheap, but the time factor is still an issue if you shoot a lot.
G
I was reluctant to answer this again as it seems to be getting a little silly to me but I really don't understand why you're insistent on pursuing this non-issue of "time" -
if you transfer using USB 2.0 at maximum speed it works at 60MB/s....
A 16mb file takes 0.27secs to transfer
A 10mb files takes 0.17sec to transfer
Therefore...
241 .DNG files takes 65.07 seconds at maximum transfer rate (60mb/s)
241 . PEF files takes 40 seconds at maximum transfer rate (60mb/s)
If someone doesn't have an additional 25 seconds to wait for files to transfer to their PC they certainly don't have the time available to process them !!
Looking at this information I just don't see how there is any common sense in recommending someone to not buy the GX10 based on "time of file transfer".
If you strongly dislike the GX10, perhaps because of the badge or other reasons then they may be more pertinent to the OPs original question.
regards

The GX10 can be had very cheaply too at the moment - £50 cashback offer...
Less the cashback it's available here for £349 (including 18-55 kit lens)

What the different camera's indicate is confusing, but I'd say the RAW file size is the important issue if you shoot RAW and care about efficiency on your computer and backups.
10 versus 16 MB is a big difference. So I'm back to Square One on my opinion of the cameras.
By the way, doesn't a constant file size indicate that the files are not being compressed?

Fair enough, I sort of see your point but I think we'll agree to disagree on this one as the OPs original question is getting a little lost in our debate

Sorry George not sure what you mean , looks correct to me, only spare space is 0.2mb which wouldn't be enough for another shot ?simonkit wrote:
They're 16.1 MB in size, doing the maths this looks spot-on....
4GB card shows 3878mb in the "format" menu..
3878 / 16.1 = 240.8 (241 rounded up)
If the K10D is showing 242 & definitely compresses the .PEF then it sounds like it must use the .DNG file size to calculate available card space/shots ?
simon
That suggests that it tells you the card is full when it is not. Hmm.Quote:

Just to confirm, Simon, what is the size of a typical DNG on your GX10?

I only get 122 PEFs on a 2GB Sandisc Extreme III.
Either the greater efficiency of HC makes a lot more difference than I thought, or the Samsung's DNGs are a lot smaller than I thought. If the latter is true, then I owe you and all the Samsungites an apology!
I have an Extreme III 2GB too & guess what....I only get 122 PEFs on a 2GB Sandisc Extreme III.

121 .DNG files - apology accepted
Unless of course you have yours set to RAW+ ??
There's always the possibility too that the K10D bases its No of shots on the uncompressed .DNG - try shooting a full card, perhaps you get a few more than the counter says - I've just done it & got exactly the same as the counter reading, 121 .DNG

If so, they must be compressed and about the same size as PEFs, and smaller than the k10D's DNGs. If so I'm wrong in thinking there's an advantage to the K10D regarding file size.
I was slightly out - 241 to be exact. (just checked) simonkit wrote:

George,
Whilst I'd agree with your point 2/3 years ago I honestly don't think its relevant now.....
A 4GB Sandisk Extreme III SDHC card costs £17.99 & holds 250 .DNG shots....
I've also read that as the .PEF files are actually compressed the .DNG format has a slight speed advantage in-camera ?
On a PC it doesn't take 4GBs worth of PEF files any shorter time to download than 4GBs worth of .DNG ?
IMHO its not sensible for the OP to base a decision to buy a camera on whether it supports .DNG or .PEF - the features of the K10D & GX10 are identical & both are great cameras, if the OP wanted the K10D but can't source there's no reason for him not to get the GX10, unless of course "badges" are an issue

It's exactly the same mechanically, but there are differences in the software. AFAIR the Samsung does not support PEF files, only DNG, which are not compressed.
That would be enough in itself to put me off.

I own the GX10 & just don't see any issue with .DNG. I've seen several poster making similar comments but from my experience any "concerns" are completely unfounded.
It uses a little more memory space but with SD cards/hard drives now very cheap this isn't an issue either
Hopefully George will clarify his "issue"

Of course a big difference lies in firmware updates. I assume the two cameras cannot share the same firmware so which company has the greater credibility in s/w development and maintenence?
That's a tricky queston as Samsung make very many products requiring embedded s/w while Pentax ...
