Since purchasing my Sony A-100 I have been using the UltraII 2gb cards and they work just fine.
When I got my new A-700, I purchased a 2gb Extreme III thinking I would see a significant performance difference. If this made much of a difference I wanted to get an 8gb Extreme III.

I really saw no difference at all. I tried the camera in the 5fps mode and just held the button down to see if one card would outlast the other.
Not much if any difference.

I then download about 100 pictures thru my card reader to the computer and again no significant difference in speed.

I took the Extreme III card back.

Any comments?

To be sure, some of the later Ultra II cards are pretty fast. But I'm surprised to hear that you didn't see much differnece between it and an Extreme III.

I did a similar test with my KM5D and found a significant difference using 2GB cards. I switched to manual focus, manual exposure, left the lens cap on, held down the shutter button (I still want to call it a 'release') and got almost twice the fps for 'Fine-Large', over three times the fps for 'Extra Fine-Large', and almost twice the fps for RAW. All my measurements were taken after the buffer had filled.

All times are GMT -5. The time now is 8:53 PM.
