I have a Konica minolta with 512 MB memory.How much more memory of SDhc/SD card can it use as it is unable to use 4GB SDHC card. Thanks.

The Z740 works with MMC and SD cards. While SDHC cards will fit into the slot, they are electronically incompatible and will not work with the Z740. You need to use SD cards, 2GB and smaller.

Your camera came out in 2003, before SDHC cards were invented. Chances are, the 4G card you're trying to use is not an SD but an SDHC card and won't work in your camera.

The problem is that your camera is only compatible with SD cards, not SDHC cards. You bought a larger card for your older camera, not noticing that it was SDHC (or not knowing that it mattered). The new card doesn't work, not because it or the camera is broken, but because it's not compatible.

Cards up to 2Gb are generally SD.
Cards of 4Gb are generally SDHC.
Cards over 8Gb have to be SDHC.

(There are exceptions. Sometimes, manufacturers make 4Gb SDHC cards but some have errors; they disable half of the chip and sell it as 2Gb, but it's still SDHC. 4Gb cards are almost always SDHC because they're cheaper, but 4Gb SD cards do exist. They are so rare that I've even seen a guru on this site claim they don't. I did own one once, but it was very expensive and turned out to be so unreliable that I had to return it. I don't recommend looking for one, because of the problems.)

Your solution is to go find a 2Gb card, and be extra sure that it doesn't say "SDHC" on it.

The X50 works with MMC and SD cards. While SDHC cards will fit into the slot, they are electronically incompatible and will not work. You will need to use cards 2GB and smaller.

The F100 works with MMC and SD cards. It will not work with SDHC cards. You need to use SD cards 2GB and smaller.

The A530 is designed to work with SD cards, not SDHC cards. You'll need to go with cards 2GB and smaller.

Your memory card reader lacks SDHC compatibility. You must either update your pc card reader to one which is compliant with SDHC or use a cheap external card reader to do the job.

SD and SDHC cards look the same and fit the same slots, but they have significant technical differences which older readers cannot handle.

The S414 was designed to work with SD cards. Your 4GB card is actually an SDHC card. While it will fit into the slot, it will not work. You need to stay with SD cards, 2GB and smaller.

Hi,

The manual lists the following SD cards compatible:

4 GB SDHC Memory Card
2 GB SD Memory Card
1 GB SD Memory Card
512 MB SD Memory Card
256 MB SD Memory Card
128 MB SD Memory Card
64 MB SD Memory Card

An 8GB card may or may not work. If you try it, make sure it is an SDHC card. (Note: HC=High Capacity)

Thanks for using Fixya.

The Dimage Z3 accept SD cards up to 1GB (Minolta says 512 Mb, and sold it with 16Mb). This camera is 4MP , and uses less memory on card, therefore a 512MB card will be enough for it.
