This card has been used in my new Panasonic DMC FZ10k digital camera and is lightning quick. In burst mode the pics load to the card almost instantly and I couldn't be happier with it's perfmormance. I also have a Lexar 32x 256MB card and itis similar permormance but this card does have faster transfer speeds (10 mbs)than the Lexar so you may or may not notice a difference depending on what your using it in.
My first digital camera used Compact Flash card. I bought a PNY card which corrupts every so often. When that happened, I would have to turn the camera off and on again (sort of re-boot), and all the pictures already taken would lost. Originally, I thought it was the camera (a HP), but after some research on the web, I found out that it was a problem common to PNY cards as well as other cheap cards.
Therefore, when it was time for me to buy a SD card for my new digital camera, I got smart this time and did the homework first. Thanks to all the reviewers on Amazon.com, I narrowed my choices to Panasonic and SimpleTech, both with almost identical specs. I purchased the Panasonic card because of its slightly lower price at the time. I now have used this card for over 3 months, and am absolutely satisfied with its performance. First off, it is very fast. My camera has a "burst" mode in which it takes 5 consecutive shots a second. This cards handles it with ease. Most importantly, this card is extremely reliable. I have taken over 2,000 pictures with it and never once had problem with file corruption.
You will take countless number of pictures over the life of a SD card, so it is well worth the extra $20-$30 for the speed and reliability. Highly recommend it with any digital camera.
My camera came with a Panasonic card, only 32 MB -too small. When I bought a larger card, I didn't know anything about them, only the shape of the card. I definitely didn't realize there was a difference between brands. I thought a card's a card. I was foolishly seduced by the Sandisk's sale price. My 128 Sandisk is noticably slower when moving pictures from the camera to my computer. Too slow for my impatient self, so here I am buying the one I should have bought in the first place.
The Panasonic list price for this item is $119.99.
I recently purchased the Panasonic 256 SD card, an upgrade from my 64 SD card that I had before and I am just as pleased with this card. I recently went on a trip to Europe and kept piling pictures onto the card, plus I used it to download my trip details, phone book and more. I really like the versatility that this card affords, and the fact that it is compatible with many different products, something that competing formats are not. My friend ran into this problem when she bought a similar product and found it imcompatible with much of her outdated products. I also found the card to be reliable--it went all the way through Western Europe and back and still works as good as new!
