Unlike 35mm photography the quality of picture will
not vary dependent on the price and quality of memory
card you buy. The nature of digital photography means
that your pictures are stored as 1 & 0. These 0's
and 1's make up the picture and because it is not possible
to have a "bad quality" 0 or 1 then the picture
is not affected in anyway by different "quality"
memory cards.
However, you will find that the price of memory cards
does vary and this is because of these factors which
are important:
- Capacity - the larger the card capacity the
more images you can store on it. See how many pictures
you can store on a memory card [here]
- Speed - faster cards will enable
you to take more pictures in a shorter space of time.
More expensive cameras may have a buffer to help also.
A faster card will also enable you to upload to your
PC faster too.
- Reliability - memory cards are
not 100% reliable all of the time (although it is
very unlikely that you will have a problem). What
this can mean is that a memory card can become "corrupt",
just like anything stored digitally on a hard drive
or other type of storage. Brand names such as Sandisk,
Fuji, Sony and Kingston are pretty good
- Formats - There are also different formats of memory
cards which affects price - more
