Lens Creep?

[Rob182]

Had a looked online at a few different lenses and some of the reviews say the bad points it has lens creep?

I have searched online but cant find a real answer, a lot of answers online are stupid like

"Its someone who stands behide you and fiddles with your lens" :clown:

Any real answers on what lens creep really is?

Thanks

Zoom lenses, when you let them hang, they unwind..

If it moves, either the focus or the zoom, of its own accord, like if a big lens weighs too much.

I think thats right.

I know nothing about cameras, but I do know that glass is essentially a very very viscous liquid. Measure the thickness of any really old window and it'll be thicker at the bottom where it has run down. This phenomenon limits the size of telescope lenses.

Don't know if that has ANYTHING at all to do with lens creep..........

Not really a huge problem on twist to zoom and focus lenses, more of an annoyance.

It was more a problem on push pull lenses because they used to slide around all over the place and probably wear out the zoom.

That's an urban myth. The window thickness thing is due to panes of glass in old windows being made of blown & spun glass instead of float glass. I think what limits large telescope lenses is simply the weight of them, and the difficulty of making such massive clear pieces of high quality glass, and the cost. Using a big mirror is just easier.

Lens creep usually occurs on plastic built lenses with heavy front glass elements. The Nikon 18-200, Sigma 18-200 etc suffer from this issue. My old 18-200 used to creep, but was never an issue for me as was always holding the lens whilst shooting anyway!

It's only really an issue if you are going to be shooting with the camera pointing up or down in a tripod. For normal use, lens creep won't really be a problem.

Exactly - I had this on my Tamron 18-250mm but it had a lock on it so it wouldn't extend out when carrying the camera about
