How strong are lens hoods?

Hey all, just a quick question; I have found a way to fit my 2 Canon bodies and 3 lenses into my DSLR bag perfectly. However, this requires me to put my 85mm Canon 1.8 lens hood on reverse, and laying flat down while a body attached with a 50mm 1.4 lays on top of it between a padded protection. Do you think over time the weight of the body can damage the lens hood or the lens mount on the lens?

I've been doing this for years and haven't had any problems. I think you'll be fine.

If you are going to have the 50/1.4 against another object in the bag, make sure you put it into MF or keep its hood on facing out. It is known to break the AF system with slight bumps to the outer barrel.

I'd only be concerned about leaving the hood on and getting bounced around if it's attached to a moving focusing element, like the 50 1.4 mentioned above.

The hood and the mount are going to be fine, but as FEChariot mentioned, the focus motor on those types of lenses might not appreciate it. On the 85 1.8 that's not a concern as it's an internal focusing design.

I know the 50 1.4 has a reputation for fragility. Leaving the hood on, especially in the extended position, should actually combat this fragility. Although the 50 1.4 extends when focusing, the outer element extends within the hood, which attaches to a static part of the outer barrel. Hood on and facing outwards (as in actual use) therefore protects the moving parts of the lens and should reduce the risk of damage to the focus motor.

Crap, you're right! I was thinking of another lens.

Strike that part from my comment, but I'll stand by the rest. If the hood doesn't mount to a moving focusing element, it's good protection.

The price of staying up too late, not thinking straight.

Well, I had go check to be sure. But, since the 50 1.4 is the lens currently on my camera and my camera was only three feet from my lap-top, it wasn't a major effort.

I really like the 50 1.4 as it happens and I seem to have a good copy that focuses very accurately and is a pleasure to use. As long as I can, I leave the hood on in the extended position all the time. I haven't broken any of those plastic internals yet but who knows whether that's got anything to do with leaving the hood on?

Luckily the way I have my 50mm 1.4 setup is that it is attached to a body and it is resting on my bag facing upwards with no hood attached. I suppose that should address any issues I might have with breaking the 50mm. At the moment, the only lens with weight on it is my 85mm 1.8 with a hood on reverse. Thanks for all the replies everyone =)

I don't use mine much anymore, the AF is a bit worthless. I could send it in for repair I suppose, but I like the 85 1.8 more anyway.

I don't think that is good enough. If you have the barrel out at all and anything pushes it in, it is liable to break. If anything pushes it even through the top of the bag, it could break. If you want to carry it that way, the best thing is to put it in manual focus and fully retract the focus barrel with the focus ring before putting it in the bag. I personally never take my hood off and never reverse it on the 50/1.4. No problems reversing any other hood however but the 50/1.4 is infamous for being fragile.

What I meant is that the lens is literally facing upwards on the bag and no pressure is being pushed on it. It is only the 85mm with a reverse hood on that is being pressed by a camera body with the 50mm 1.4 attached. Hopefully it's not confusing lol, I can post a picture if it helps. Thanks for everyone's help though =)
