Really, the logo is there for the owner to look at and stroke it a la Gollum "my precious."
The notion of being a photographer in a combat zone and covering a logo would make the difference between getting shot or not is complete BS. But if folks think it makes a difference and the magical tape protects you, then perhaps it is the psychosomatic at work.
One old combat photographer I knew out in Iraq used a Nikon D1 and a chrome F2. No tape on either. He got out just fine. Personally, I used a Nikon D2H and two chrome Leica M bodies. The Leicas didn't have logos as they were M2 and M4. I got shot at so much that I can't count the times. Maybe I didn't go far enough and should have taped my Leicas with dymo or electrical tape. The real reason was probably that I was dressed in US camo, therefore a legitimate target. Add to this the fact that if someone shoots through that red dot, then they are just messing with you and they were going to kill you anyways. Not to mention, they are a world class sniper. If you don't want to get shot in a combat zone, don't use a flash and don't be a smoker. After that, everything is fair game these days.
This is just so much ridiculous drivel. Taping a camera does not make it invisible. It makes the camera a more obvious personalized fashion accessory. Your body language and comfort in-situ are what make the camera less visible.
