For my new Konica KD420 my photo dealer has recommended a Panasonic card. Which reminds me immediately of price slightly richer noticed (compared to other manufacturers). Nevertheless, I bought the 256MB card, and I have to say it was worth it really! Since the card is 10Mbit fast, I can now picture after another shooting, without having to wait until it is stored: storage time at 4 megapixels and lowest compression (highest quality) not even half a second !!! I highly recommend this card so anyone, even if it is a bit pricey. It is absolutely worth the money and out super fast yet very safe and reliable - in half a year and about 8000 images not a single lost or damaged. So it must be!
