Hi Just need to know what form of SD cards can be used once the firmware on my K100D has been installed? I'm looking to buy a Lexar 64GB SDXC card, or if anybody can tell me what the best 64GB card would be to purchase.I don't believe that there is any firmware update that will enable a K100D to use SDXC cards.

Nor would I expect such an update to be released. In other words, don't waste your money on a 64GB card. With the firmware update that IS available for the K100D, the maximum size card is 32GB. Why do you think you need a 64GB card? Your K100D, like my K10D, doesn't do video. On my camera, shooting RAW+JPEG at the highest resolution and quality, I could fit 4,096 images on a 64GB card. My camera accepts SDHC cards, so I could go as large as 32GB, but the biggest I have is 4GB.

Pentax has today released the latest firmware update for its K10D DSLR. Following the lead set by its recently announced K100D Super, the release adds support for SDM.

Does anyone have instructions on how to upgrade my firmware (K100d). Hi I bought my Pentax K100d around end of January. Flickr, a Yahoo company. Sep 25, 2007 UPS just delivered my new K100D. I saw the 1.02 firmware on pentax website and mine had 1.00 so decided to update it. Following the instructions.

That is far bigger than I ever fill in a single shoot. Cards do go bad occasionally, and they can be lost or stolen. I'd rather not lose several thousand images due to one failed card. Of course, your needs and shooting techniques could be very different than mine. Its your choice, but I don't believe that 64GB is a choice for you.

I'm late to this post, but am trying to update the program on my camera. I have a Pentax K100D and have been trying to follow the directions above for installing and updating Firmware. I currently have version 1.00, and have formatted and copied the required file onto a SanDisk 4GB memory card. The card is now inserted into my camera.

However, whenever I turn on my camera while pressing the Menu button I don't get anything saying 'Loading' or 'Updating'. Mine simply tells says: 'Ver: 1.00'. Is there something that I'm doing wrong? I just want to say thanks for having this thread.

I was ripping my hair out trying to figure out why my new 8gb SD card was not working. A quick search on the net came up with this thread and it helped me right away.

The process up updating my K100D to the 1.02 Firmware was quick and easy. Now my new SD card works and I can continue to take pictures. Thankfully I tried the card before going on this road trip tomorrow. I would have been more upset trying to figure out while on the road. Now I am in the clear and do not have to worry about it. Thanks again to all involved in making the thread and posting the answers.

You all are a great help in this community. Read the entire thread and still cannot update. Followed the instructions and all goes great until I get to 'Turn the camera power on while pressing the MENU button.'

Download Monster Hunter Iso For Ppsspp Iso. I just get the 'vers 1.00'. I have a 1Gb SD Extreme III card, so I though it was that. I have tried another SD card, a 8Gb Ultra card. Still the upgrade does not start.

The reason for doing this upgrade is due to the 'Battery depleted' being displayed even with new Duracell's and fully charged rechargeable's. Irrespective of this error, I would like the firmware upgrade to complete. ANY help will be appreciated. Thanks a million! Read the entire thread and still cannot update.
