Memory Cards and Image Quality

[nimblybimbly85]

This may be a stupid question, but i am new to dslr photography and I'm trying to learn as much as possible..





Do memory cards have any effect in image quality?





After I bought my XSI, I didn't have much money left and I purchased a Sandisk 2 GB card. I notice some people list the types of cards they have in their equipment list. Are there good and bad types/brands that effect image quality?





Thanks a lot!

No, the capacity, speed, and brand of card have no effect on image quality.


The capacity affects how much data can be stored. The speed affects how rapidly the camera can write images stored in the camera's shooting buffer onto the card. The brand of card may or may not be associated with its reliability.

On a slightly different note (sorry to highjack the thread but the original post has been answered) what are people's thoughts on the different brands of CF cards? I've always used Sandisk card without any issues but the Lexar UDMA cards are pretty attractive for the price.

I just bought a x233 udma lexar 16gb for my 5d II and its been fantastic. I had a 4gb extreme III sandisk before and this is just a bit faster and quite a lot larger. No problems so far.

what do you mean by a card being "fantastic" is they don't have anything to do with image quality..

Some people appreciate having a fast card that performs reliably for them, especially at a low price point. The big names (SanDisk/Lexar/Kingston) are generally slightly more expensive but are relatively more reliable than the more obscure brands. An unreliable card may show read errors in the form of corrupt images, for example. If this occurs even once, I personally recommend throwing away the card, as it can no longer be trusted to record data correctly (it also signifies that there may be a problem with the overall manufacturing quality).


I usually stick with the big names, and I never buy the largest capacities or the fastest speeds available, because these features are usually priced at a steep premium. I'll buy a moderately-sized card, one that meets my needs, with a speed that is sufficiently fast for the camera I am using. In a few years, what is considered top-notch will be middle-of-the-pack, and will be priced accordingly.

Just don't buy those cheapest cards you could find. Some images may be lost when you checked it in the computer. This usually happens when you shoot continuously. I only use Sandisk for my high speed needs.

Agreed. But Lexar have a pretty good reputation. I probably woouldn't go for any manufacturer other than Lexar and Sandisk but sometimes I think you can pay that bit more for the Sandisk name.

Write speed and reliability are probably the two main reasons one would be satisfied with a memory card.
