First let me say I found your site while researching SD cards. Cannot wait to read all your tips. I am going on a 10 day trip to the Galapagos Islands in October.
I read that the new higher speed cards would work in my camera, but I wouldn't get the benefit of the speed. Is this correct? Which SD card would you recommend? I do plan to download my pictures to my laptop and another storage just for safe keeping. I recently lost pictures when a hard drive went bad on me. Should I download to the second storage device or plan on when I fill the card keeping it intact?
My second question is on your cheat sheets. I plan to order the one for the 75-300mm. I also have a Canon 28-200mm. Would you have one that works for that lens?
