|Pentax K10D - DNG & PEF image formats & software
You can take photographs in both RAW and RAW + JPEG with the Pentax K10D. You can choose from various JPEG settings and, more uniquely, from two types of RAW. Pentax's own format, called PEF, is approximately two to three times smaller than DNG, but you can only convert it at the moment of transfer with the PhotoLab supplied by Pentax. It is a good program, but all those separate windows make it a bit difficult to oversee. Adobe Camera RAW Works better in this regard, but it can't cope with the Pentax K10D's PEF files. Neither can the beta version of Photoshop CS3. The Adobe format, DNG, doesn't have this problem. For me, that's reason enough to work in DNG. You can also choose from more programs, but DNG is not as universal as Adobe claims. For example, the DNG files from the Pentax K10D cannot be opened in Aperture.
Pentax K10D - 2GB Secure Digital / SDHC memory card
The continuous increase in pixels requires a corresponding increase in the size of memory cards. We also do not want to have to keep on exchanging cards. We are getting a bit spoiled. With film, we could only take 36 pictures in a row. Overly large cards are also not ideal. If you lose a card like this, which is only too easy with a small Secure Digital format, you lose an awful lot. You will need to find a balance between the number of pictures you want to take and the risk of losing data. If you are taking pictures in RAW, which I would certainly recommend, you will need large cards for the Pentax K10D. I would recommend a 2GB card and a 1GB card at the very least. The following table shows the number of pictures you can make with a 1GB SD memory card.
Considering 1GB storage capacity:
RAW - DNG - 3872x2592 pixels - 59 pictures
RAW - PEF - 3872x2592 pixels - 59 pictures
JPEG - 3872x2592 pixels - best - 202 pictures
JPEG - 3872x2592 pixels - better - 345 pictures
JPEG - 3872x2592 pixels - good - 592 pictures
JPEG - 3008x2000 pixels - best - 337 pictures
JPEG - 3008x2000 pixels - better - 575 pictures
JPEG - 3008x2000 pixels - good - 990 pictures
JPEG - 1824x1216 pixels - best - 915 pictures
JPEG - 1824x1216 pixels - better - 1549 pictures
JPEG - 1824x1216 pixels - good - 2627 pictures
|Pentax K10D D-SLR - Buffer & Picture speed
It takes a lot of time to transfer large files. Fortunately, the buffer can come to the rescue and the Pentax K10D's buffer is large enough for most circumstances, especially as the camera's picture speed is average at 3 fps. Photos are transferred quickly from the buffer to the memory card. It would be wise to choose a quicker card, like the SanDisk Extreme III. The Pentax K10D clearly benefits from quicker memory cards.
Pentax K10D SLR - USB 2.0 Hi-Speed interface
The pictures can be transferred directly from the camera to a PC or laptop via the fast USB 2.0 Hi-Speed interface. Thanks to the combination of this fast connection and a fast memory card like the SanDisk Extreme III, the digital workflow is not likely to be hindered by delays. If you would prefer not to use the camera to transfer data, you can use a card reader. This equipment is invaluable in a digital working environment and makes transferring data a lot easier. SanDisk's USB 2.0 Hi-Speed Extreme card reader is currently the fastest (besides FireWire) and transfers data at a maximum speed of 20MB/sec.
Pentax K10D digital SLR - Li-Ion D-LI50 battery
A Pentax Li-Ion D-LI50 battery supplies the energy. According to the specifications, it can take approximately 500 pictures. In my case I didn't reach that figure, but 400 is certainly realistic. This is a great performance. You can insert a second battery with the battery grip and this will let you take pictures for longer. You can select whether to use the battery in the camera or the one in the hand grip first via the menu.
