This is a YouTube channel I really like to learn about photography. They present the lessons in a fun and cheeky format with professionally done videos.
Think protection doesn't matter? Here is some fun testing of camera bags.
Part 1 - Water and Drop
Part 2 - Drag and Burn
So once you have invested in all the new gear - make sure you get a good bag to protect it. No pro photographer carries their cameras and lenses in a bag that allows them to move around.
The people in those videos are complete idiots. The last thing you ever want to do is start activating the shutter release without a lens attached to the camera body. Doing this will allow all kinds of dust and debris inside the body of the camera and onto the sensor. Not only will all that dust show up in your image, it will also end up in your viewfinder and make it difficult to compose an "important" shot later unless you send it in and have it cleaned. I have an idea John, why don't you call Nikon or Canon and ask them how much it is to send your DSLR in and have it disassembled and cleaned.
Additionally, trying to hold a lens that close to the camera body is going to guarantee that you bang the lens mount against the lens. There are electronics mounted in this area that can be damaged very easily. Not to mention the only people that would be uninformed enough to try something this stupid would be amateurs and would most likely have lenses that are not pro quality and have plastic mounts which would be damaged easily.
So yeah, run around with the lens off holding it against the camera body and let me know how that works out for you. When you attach the lens again to take a "real" image and the camera doesn't auto focus anymore, or read the information from the lens as it should, let me know how that works out for you.
I'm sorry that you can't see that I made this guide to try and help the others on this forum take better photos of their cues and enjoy their hobby a little more and maybe even get them interested in another one. While I appreciate your sense of humor, if you want to post amusing videos please do so in another thread. I'm sure you have plenty available of case making that will be sure to get a laugh.
