Depends on the camera. Many newer cameras can utilise the increased speed of the faster CF cards (Nikon 3100) and higher capacities. According to Nikon and other sources older cameras (I have a Nikon 995) cannot utilise the extra speed and slows dramatically when cards larger than 256MB are inserted. The main benefit in my opinion of the higher speed cards is that there is less delay in saving images and so less time between shots...
Hey Mark, thanks for the reply, I have since came across this page http://www.robgalbraith.com/bins/multi_page.asp?cid=6007-6425 it has a very comprehensive data on different CF on different camera. Regards,.
Does the Canon A70 have the capability to make use of the the extra speed CF cards like the Sandisk Ultra or Ultra II??..
Chris that I wouldn't know for sure but I kinda doubt it cause I read somewhere that Canon doesn't support some high speed write architecture. But one thing I can be sure of is that if you have a USB 2.0 or firewire card reader, the faster card will definately transfer data from your card to PC much much faster. I currently have 3 x 256MB Sandisk Ultra II cards for my Canon Digital Rebel. Regards,.
Even if your A70 could adapt such high speed like the Sandisk Ultra II (i.e. 10MB/sec READ and 9MB/sec write) your A70 just don't have the performance power to use such high speed anyway. If you want to take faster shot per shot then you could use this high speed CF card, but I recommend medium cost brand will do the job just fine. http://www.dpreview.com/articles/mediacompare/ But if you want a really fast transfer to your computer then use a reader, because the transfer rate of using USB cable links from camera to computer are usually about 400kb/sec, but if you use USB card reader (generally faster than cable links) that have a transfer rate ranges rom 600kb/sec to 480MB/sec depends on which model ofcourse. http://www.steves-digicams.com/digi_accessories.html#readers..
