I've got a xsi, and a bunch of sd cards. I am looking at a 7d, which uses CF. I plan on keeping the xsi - sometimes it is just too handy to have 2 bodies with different lenses.
I'm bummed that they use different cards. Just one more thing to keep track of. Not a huge deal - but who needs it?
I'd like to hear from someone who has first-hand experience with the cf-to-sd adapters. The sd card fits right inside a cf footprint which then goes in the camera - in this case the 7d. The reviews are all over the place, regarding speed.
Any experiences you could share would be welcome.
