|Pentax K100D - Secure Digital memory card
The Secure Digital (SD) memory card is used more and more often with digital SLR cameras. Naturally, the main advantage is its compact size. Besides saving users space and hassle when taking it along, it makes it considerably easier for manufacturers to design smaller, more compact cameras. SD cards are available in many different versions. Unfortunately, the Pentax K100D is not SDHC compatible, which means that the camera can be equipped with a maximum memory capacity of 2GB. Perhaps a firmware update will allow SDHC, which will enable you to use significantly more memory. It has to be said that would certainly be a welcome addition, especially when photographing in RAW. It is also advisable to choose a fast version of the Secure Digital memory card, such as Ultra II or Extreme III by SanDisk. I would recommend using a memory card of at least 512MB, or even 1GB if you can. The following table shows the amount of images that will fit onto a 512MB card.
Considering 512MB of storage capacity:
Resolution RAW - 3008 x 2008 pixels - 46 images
Resolution JPEG - best - 3008 x 2008 pixels - 167 images
Resolution JPEG - better - 3008x 2008 pixels - 311 images
Resolution JPEG - good - 3008 x 2008 pixels - 498 images
Resolution JPEG - best - 2400 x 1600 pixels - 234 images
Resolution JPEG - better - 2400 x 1600 pixels - 415 images
Resolution JPEG - good - 2400 x 1600 pixels - 674 images
Resolution JPEG - best - 1536 x 1029 pixels - 453 images
Resolution JPEG - better - 1536 x 1029 pixels - 722 images
Resolution JPEG - good - 1536 x 1029 pixels - 1115 images
|Pentax K100D - Shoot series of images & Buffer
With 2.8 frames per second, the Pentax K100D digital SLR camera isn't super fast. In practice, however, it is likely to suffice. Every now and then, you should perhaps ask yourself how often you shoot series of images. The buffer will fit 5 JPEG or 3 RAW images, which isn't that much. Fortunately, the photos are written onto the memory rapidly, provided you use a fast card. The fast USB 2.0 connection allows you to transfer the photos to a computer.
Pentax K100D - NiMH batteries & CR-V3 batteries
Just like the previous models, the Pentax K100D uses regular AA batteries. In fact, Pentax supply a set with the camera. Naturally, these batteries can also be replaced by NiMH batteries, which are more environmentally friendly thanks to the fact they can be re-charged. In addition to this, you may also opt for two CR-V3 batteries. All in all, the Pentax K100D offers plenty of options, which is a definite advantage. Batteries can be purchased virtually everywhere, whereas this is not the case with a special battery. And let's be honest, taking your charger everywhere you go isn't exactly handy either. Even though the Pentax K100D features an image stabilisation, the camera remains economical with its power. A set of re-chargeable NiMH batteries easily allows you to capture several hundred photos. Alkaline batteries will enable you to shoot approximately fifty images. Although this is great for an emergency situation, Lithium or NiMH batteries will be better for serious photography. Considering the fact that Pentax state this clearly in the user manual, it is a bit of a pity that they do not supply a set of NiMH batteries with a charger.
