I'll not vote either but, one reason why one might remove the lens is that the contacts will be wiped by the action of removing the lens and again by fitting one. Anything that keeps the contacts clean may be seen as beneficial, but it might be inconvenient so the answer is, it depends.
Wrong question!!
I fired “lens on” but not because there is less overall risk in fewer lens changes.
If you want to talk about wiping contacts, think of what is wiping those contacts: metal. Every lens change is metal-on-metal scraping. Eventually you will wear down one side and have problems - if you think about things that way.
Some might suggest if the camera and lens are in a bag you cannot be instantly ready for the next shot :-x
Great advice, makes sense. Many thanks.
I'm not following how it would make a difference regarding the pressure.
For me I keep the lens on out of necessity. Like, it's the only way to fit three lenses and a body in my Think Tank Change Up v2. And actually, I'm trying out the Think Tank modular belt system with the DIgital Holster 20, which again, is made for putting the body in with a lens attached.
I'm still not following why this makes a difference. If a force hits the lens, well the body would also be subject to that force if it's attached. So it would simply move with it, right? I mean, both items are in the bag. They are not held tightly therefore. So I really don't see the issue with external forces.
Well for sure every time you change a lens there is a danger of dropping it!
