Question: Work with Rebel xti? Does anyone know for certain that this works with canon rebel xti?
Document: 2 CF cards were purchased. Both appear to work in the camera (Canon Xti) but neither is readable or formattable on the computer CF drive. The drive works fine with other SanDisk cards. I emailed SanDisk support, have received no response. Though I can use the cards in the camera and download via cable, I am not confident in the reliability until I know the problem: the card? the distributor (is the card authentic)? the drive?
Bought this for my Canon Rebel XTi DSLR and it's working great. great performace and price, can't go wrong here!
Fast, reliable memory. Had no problem with it. I Have been using it since march 2007. In a Canon Rebel Xti (10Mpx) it gives me about 800+ Shots.
I'm surprised how brick and mortar stores can charge almost twice as much for this 4GB memory card with a straight face. I use this card with my Canon Rebel XTi and the card is plenty fast for continuous shooting (even in RAW)- so there was no need for me to step up to the faster Extreme III card.
This memory card is awesome. I purchased it as an upgrade to my 512 mb card. Let me tell you 4gb is a ton of space. This card will be used in my Canon Rebel XTI, and on the highest setting it will hold approx. 900 photos, and on the lowest setting over 5000. I will be purchasing another card very soon. I would recommend this card to anyone.
I bought this memory card to use it with a Canon Rebel XTi. I think that this size is the perfect size: more would take too much time to copy on HDD, less would mean fewer pictures.I haven't noticed any speed problems, the combination of the camera and the card assures the enough number of photos on the running mode.The problem that I have right now is that I need space to download the photos from the card.
I was impressed with how quick and easy this card was to use. I read a ton of reviews about how some cards aren't fast enough or large enough, but this card did just what I wanted. I took rapid-fire pictures (and a lot of them) in dim lighting. The pictures just kept coming and I was easily able to get over 500 pictures onto this card. It's worth every penny and I will be purchasing another one from my Canon Rebel XTi!
I work as a professional sports photographer, and I'm thrilled with the performance of this new CF card. It handles full bursts and 1080p video from my Canon 7D without a problem, and since it's an authentic SanDisk CF card, I know it's of great quality.
I got it for my Digital camera (Canon Digital Rebel XT)Canon Digital Rebel XT 8MP Digital SLR Camera with EF-S 18-55mm f3.5-5.6 Lens (Silver)it doesn't work! Honestly, I took a few picture with that, but after that the camera gave me error message and didn't accept it anymore. The packing also was awful, I haven't seen this kind of ugly packing before, without any box. I don't recommend this "ULTRA" company at all.
Pretty straight forward purchase. It was exactly what we needed. Works great with our Canon Rebel XT.
Answer: Yes, the Rebel XTi will accept both compact flash type 1 and 2 discs.
