Im wondering what your opinions are regarding Sandisk and Lexar, I am looking at the 90mbs CF offering's from both company's, I currently have 2 Sandisk 32gm 60mbs cards, but im going to be needing either another two 32gbs cards or one 64gb card. The Lexar being about $100 cheaper, wondering if its quality is the same or if I should just stick with Sandisk. Also will the 60mbs be more than enough for the 5dIII, shooting wedding's (photography) and video (for fun) primarily. Appreciate the comments.
For weddings and video, the cards you mention will be fine. for those shooting high frames per second, faster cards will clear the buffer more quickly, but for video, it does not speed up the capture process.
One thing to consider is how long you are willing to wait for a 60gb card full of video to download to your computer. A very fast card and fast reader will greatly speed that up, but if you are willing to go away and do something else for while, a USB 2 reader will work.
I'm planning to get a new PC with USB 3 this fall when windows 8 comes out, so I'm using usb2 right now. I sold my firewire 800 readers for far more than I paid for them to help finance my 5D MK III. I had not used them for over a year anyway.
