Pentax K100D FAQ
What battery does the Pentax K100D use?
Pentax K100D uses 4 AA batteries. When buying used, confirm the seller includes a working charger or plan to add one. See the battery guide for charger and spare-battery checks.
What memory card does the Pentax K100D take?
Pentax K100D uses SD/MMC card. The current buyer-facing maximum is Up to 2GB (SD/MMC; early body, smaller cards recommended); for older or unusual formats, stay within that limit and avoid oversized cards. See the memory card guide before buying cards for older cameras.
Is the Pentax K100D worth buying used?
It can be worth buying if you want a 6 MP Pentax digital camera from 2006 with APS-C (23.5 x 15.7 mm) CCD. Check power, lens movement, screen condition, and storage access before paying. Run the used digital camera checklist before buying. For nearby Pentax options, compare Pentax K-x and Pentax K100D Super.
How do you transfer photos from the Pentax K100D?
The simplest transfer path is usually to remove the memory card and use a compatible card reader. If the camera uses internal storage or a rare card format, confirm the cable or reader before buying. The card reader guide and photo transfer guide cover the common options.
Pentax K100D is worth judging as its own Pentax K-mount DSLR body, not just as a generic old compact. Start with condition, the exact battery/card setup, and whether its look fits what you want to shoot.
What owners like
Pentax K100D works best when you want simple snapshots, direct flash, and the relaxed character people look for in older digital compacts rather than a technically perfect modern camera; its APS-C (23.5 x 15.7 mm) CCD and interchangeable lens mount are the main character of the look.
Common complaints
Check the lens movement, flash, screen, buttons, and card door calmly before relying on it; older compact bodies can need a little patience without being a bad buy.
What to compare
Compare it with Pentax K100D Super, Pentax K10D, Pentax K110D, Pentax K-01 to decide whether you want this exact body, a cheaper nearby compact, or a slightly more capable alternative.
