If I can MF the MP-E 65mm at 5:1 with the Rebel VF, I sure as hell can MF any lens with this 7D. You guys whinge too much. Max aperture on the MP-E 65mm is f/2.8. Stock focusing screens can show accurate DOF for f/2.8. It's when you get to larger apertures that you start having problems. When an f/1.2 lens has DOF like an f/2.8 in the viewfinder, you're not sure if you've nailed focus or not until you've taken the shot. Have you no experience with macro, let alone at 5x mag? If you did, you would understand that the DOF is literally razor thin even when stopped down. Remember, distance plays an enormous role pertaining to DOF, the closer you are to the subject the less perceived DOF. Yes, the closer you are to the subject the less perceived DOF. That's a given. But it is my understanding that a stock focusing screen would show the proper DOF for an f/2.8 and smaller lens regardless of distance and actual DOF amount, whereas the same focusing screen would not show proper DOF for lenses larger than f/2.8 (I think the actual number is f/2.5?) regardless of distance. Am I wrong? I'd love to learn if so.
It's not about how small the DOF is. It's about accuracy of what you see vs. what you will capture.
Yohan, you are basically right, but bringing DOF into it just confuses these poor fellas.
