Barry Rice asked:
Are all SD cards more or less equal, given storage volume? (I see B&H has
some 1Gig Sandisks from $88, which looks ok.) I have downloaded the pdf
manual on the DS, and estimate 1Gig would hold about 86 RAW images. If
this
disk fills up in the field, can I slip in a new one, just like changing
film?
Since you are talking about use of the DS in the field, it sounds like you
are more concerned with writing time than uploading time. Unless you are
going to shoot in bursts, the SD speed will not be a factor. Get large
enough storage from reputable manufacturers. The usual suspects (e.g.,
SanDisk & Lexar) pertain.
For speed of uploading, use a card reader. They are fast, cheap and
reliable. Additionally, there is no strain on the DS batteries.
Changing disks in the field is easier than changing film. Your DS is a
computer. I would use typical caution, and turn off the camera while
changing SDs. Nothing untoward may happen if you change SDs with the camera
on, but ...
