OK, I'm a newbie to the forum with a question. If it's already been answered somewhere else, please let me know. Here goes:

I use my Olympus E-Volt 500 to do sports photography--specifically, horses jumping; so, timing is critical, because you have to catch them at exactly the right moment at the arc of the fence. I used a Nikon 35mm for years and had my timing down perfectly. With the E volt, my problem is that I'm always a fraction of a second too late and don't get the shot I want. I know this is caused by a lag in writing to memory, but what do I do about it?.

I talked to someone the other day who said that I needed a faster card. She recommended that I get a card designated "Pro" and said that would help solve my problem. Is she right? If so, my question is--what card? DX or CF?

I know there's been a discussion here about Dx vs CF and the answer seemed to be "CF cards are faster", but what is a "Pro" card and will this solve the lag time issue?

Thanks for any advice.
