Help please. Lens is loose in mount.

I shot the ellipse yesterday and noticed when I returned home the lens was loose in the mount. I've checked, and it is fully rotated and "locked". This is not normal is it? What is the fix? (I didn't notice any light leaks in the pics and didn't notice any loss of sharpness, but I was shooting at 11mm on a crop frame Nikon.) Thanks for the help.

A slight looseness is absolutely normal. If the lens fit too tight it could jamb and not come off. Nothing to worry about at all. Camera mounts and lens mounts are made to a tolerance so the amount of slack will vary between lenses.

Oops. It's the lens (Toking 11 - 16 f2.8). My Nikon lenses are tight. The cap on the lens' camera mount end is also loose. Where do you get Lenses repaired and do I need to?

Thanks, MT Shooter! I've been very happy with that lens, but never noticed looseness until yesterday.

Sorry, but that is not normal! In all the cameras I've owned in well over fourty years, I never had any slack in any of them!

I've had SLR and DSLR cameras for a long time. This was the first time I've noticed, but I cannot think of anything I've done like a hard bump or drop that would have caused what I'm seeing. All the rings and screws appear to be in place, snug, and tight.

that's what I was thinking...
I saw a video yesterday of a Canon 350D with a long lens on it that got totally toasted looking at the sun.

This was a wide angle, never pointed directly at sun (approx 30 deg off center), and I had a 18 stop film on except for totality.

My 70-200 had a screw come loose at the mount. I tightened it and no probs since....

Three screws loose. Tightened. Works great. Thanks to you and crazydaddio.

You made me get up out of my comfortable chair and walk across the room! The 28-300mm on my D750 has a slight bit of wiggle room and so does the Tamron 18-200 on my A6000.
I'm glad you found and solved the problem. That's what I like about UHH - so many solutions! For future repairs, get a set of JIS (Japanese) screwdrivers. They fit the Japanese screws better. Lots on Amazon.
