I read earlier on UHH on a discussion of memory cards when a
member gave a reference to an article online that gave a fairly
complete explanation of which memory cards to use in different
cameras and the meaning of the numbers, letters, and symbols
on the card. I know which is best for my 5D and 7D buyt the
rest is confusing. I am almost 77 and have enjoyed photography
as a hobby for years, but I always need to know a lot more. I read
from UHH every day.
