Hey guys,

Just wondering if i could get some advice?

I have the Sigma 150-500 and the tripod mounting ring is a smite stiff and bitey... I was wondering what woukd be the best grease to use to free it up and get it rotating smoothly. Would it best using mineral or silicone grease, or something else?

Thanks

Normally none is needed but I doubt a small amount of a silicon-based lubricant (oil not grease) on a lint free cloth would do any harm. What matters is whether it compromises any rubber seals. I have the same lens and it fits reassuringly smoothly.

You should try using a wax based lubricant, if any. Dirt, grime or whatever other sh!t you may encounter won't stick to it,

Would beeswax do the job?

what body is the lens going on. Thinking about the Issue with Sigma mounts on the K1.

It's a K5.... but its not the actual camera mount... its the lens mounting ring to attach the lens to a tripod /monopod

I don't know. The best place to find wax based lubricant is a bike shop. They use it for chains on off road bicycle and motorcycle so dust or dirt won't stick.

It sounds as if something has got under or around the ring somehow, I would have thought the best answer would be to get it repaired rather than the risk of making things worse; I had the same issue with some old binoculars, tried the same as you suggest with Vaseline and they were never right afterwards.

Doesn't the ring/tripod bracket just slide off when loosened? Check it hasn't somehow been deformed.
