p.2 #1 · Penny wise, pound foolish?

I always had great results from Kingston RAM for my computers in the past, never used their CF cards though. Personally, I subscribe to the notion that your CF cards are your photos. When I'm doing a shoot I absolutely cannot take any risks on having unreliable cards, so I use Lexar 300x cards, which have worked flawlessly for me thus far.

I contacted Kamera-Express, I will return both cards and just wait and see. But you know .... it's just like when you have tooth pain, the moment you contact the dentist ..... the pain is gone.

I tryed one card again, made almost 150 images (RAW + JPG) and you know what, NO "CHA" ERROR. AARRHHHHH

Ernst, how rapidly were you shooting, as in frames per second? You may also want to check your camera settings for noise reduction, D-Lighting, 12 vs 14-bit RAW, etc. as those settings affect the camera buffer. Slower cards may not experience write problems provided you are not exceeding the camera buffer, but once the camera buffer gets near it's limit, a slower card wont be able to keep up and may cause the error you are experiencing.

To check the size of the camera buffer, turn it on (you can leave the lens cap on) and half-press the shutter release and check the top lcd panel for where the shots remaining indicator is. When you half-press, the shots remaining number changes to "r ##" where the ## indicates how many shots at your present settings the buffer can hold.

Just a thought.

Hi Cris,

I got the "CHA" error shooting in single mode, I never shoot in continues mode (maybe somewhere in the future). The camera is in 12bit mode and when pressing the shuuter release ½ way it tells me R06.

Thnx for your advise ...

To all,

Here's some feedback.

A friend of mine tested one of the cards in his D300, he didn't get any error or what so ever. So I tested the same card ..... and you know what, no errors.

I have to say that I formated the cards again before I handed over the card to my friend.

@Kamera-Express they where willing to help, but now I don't know if I should do so.
I ordered a new Sandisc card and will go on holiday first and just wait and see.

Once again thanks for your advice.

Ernst

I have bought 5 kingston cards, 1 of them functions properly. It is kind of annoying when you buy original, quite expensive (here in norway :P ) memory cards, and then you can't trust them beacause they go "cha" and will have to be formated to work..
