Pentax K-X Firmware Update Irony By: David Rader II on February 04, 2010 @ 2:45 PM
I recently purchased a Pentax K-X digital SLR camera. I love it. The photos taken with it are great (for example, this picture I took of my wife holding our son born last week (Jan 29th at 4AM) without a flash and on auto:
The funny thing about the Pentax concerning the firmware is it doesn't meter the battery properly. Rarely it tells me new batteries are dead and often it things old batteries are fully charged. Despite this, they recommend using it to judge the safety of an operation that could "brick" or make your camera inoperable.
On their firmware update page, they say if using batteries while updating make sure the "battery level indicator is displayed “Green” (Batteries are full) before updating". Ironically, this is the very thing there's a problem with - You can't rely on the battery indicator.
Worse yet, Pentax further indicates "If the camera turns off during updating due to lack of battery power, the camera will become inoperable. If this happens, a charge will be made for repairs even if within the warranty period." So don't trust the battery indicator as recommended by Pentax! At least not until you fix it, lol.
My suggestion is to put a fresh pack of Energizer Ultimate Lithium batteries in if you have to use batteries. They're flipping amazing. They actually stand up to their "8x longer in high tech devices" claim.
I haven't used the camera much since I've (successfully) updated the firmware, but I always carry an extra pack of batteries anyway.
