IDK...i suppose it might. I personally prefer CF because they are more robust and you can get some super high speed ones. SD cards are a lot cheaper, so if I have to add some that is some solace.
There are two ways to look at this:
1. I want my rebel users to upgrade, so I'll put SD card slot in so they can use their current stuff.
2. I want this to be a gateway to pro models, so I'll put a CF card slot in to make the next step easier/give it the feel of a pro set up.
Maybe it'll have dual slots so they can cover both bases? I wish! But not going to happen in an entry level body.
Sorry, but do you ever use SD´s? They´re fast, durable & cheaper than cf´s... For exemple the 16GB SD Extreme Pro 95MB/s from SanDisk for only 33 €, instead of more than 100 € for an CF Card with this speed...
No, I don't use them very much. As I said in one of my earlier posts, I have CF cards for my 40d and 5d. I do have a couple of older SDs for a point and shoot, and a pair of micro SDs for some android tablets. They are the same model (Sandisk Extreme IIs i think) as my CF cards, and not as fast to transfer despite the label. I do realize this isn't a scientific test, and SD cards have advanced quite a bit along with CF cards over the years. They also seem fragile, though I've never broken one of either type.
I simply find the CF card a more pleaseing format for me. Definitely not a deal killer though. Murphy's laws would imply there is a 100% chance of this cam being SD based, since I just bought a new set of CFs. LOL. But time will tell.
I see the 7D AF thing has popped up again - there is always one person talking bad for every 5-10 in a thread that talking good about that AF system. I wonder if there is a QC issue, or if its a learning thing. I'll have to do some more research.
