Is there a difference between SD memory cards for cameras?

I see regular SD, SD/HC, Ultra III, and a few other tags on them. Is there a difference in writing speed with these? Is this what contributes to shutter lag on digital cameras?

Is there a difference between SD memory cards for cameras?
Ultra, extreme, etc. is usually a designation of faster read and write speeds. SDHC means Secure Digital High Capacity - which won't work in all cameras, so you'd have to check your manual to see if it works with yours. HC does not necessarily mean faster speeds - just a higher storage capacity category.





Generally speaking, just about any card regardless of it's speed will serve your purposes, unless you're working in a professional situation where every minute of your time needs to be managed as efficiently as possible.





Also, this is not what causes shutter lag - that's a product of the camera's need to focus on the image and obtain the proper exposure settings.
Reply:SD=Secure Digital Card(16mega-2giga)


SDHC=Secure Digital High Capacity Card(4gb-8gb)


Ultra ll/Other= Faster Upload/Download times





*Kingston SDHC 16GB comming soon!!!


*I dont see a differance with my Sandisk Ultra ll and Kingston 2GB


*Recomended by me=Kingston SD OR SDHC
Reply:The HC just tells the consumer it is a high capacity card.. Writing speeds are only important if you are saving large files while shooting in the continuous mode.





Shutter lag is caused by the design of the compact digital cameras.
