FS7: moving adaptors

I have several lens-adapters from different brands, nikkor to e-mount and canon to e-mount and all of them are a bit loose on the lenses. Is there something to solve this problem?

Which brand adapters? I have an Optitek EF to FZ and a Metabonez EF to FZ and both are rock-solid once locked down. I use the Optitek with my CN-E primes and the Metabonez exclusively with still lenses, because it has an aperture control ring to mimic an actual aperture ring built-in, and even with a 70-200/2.8 and 100-400, I've never noticed any movement/wiggle between lens and adapter. These are also ~$1,700 and ~$1,000 adapters, respectively.
 
I have metabones (dumb adapter) and commlite. They work well on the camera side but on the lens side there is no friction and it feels there is some slack.
Tape is an option but not preferred.
 
It depends on 'tight'

There is rattly and then there is FIZ proof.

Im serious.. 3mmX6mm strip of tape will work wonders
 
I'll give it a try. you mean tape between the elements or tape around the combination lens/adapter?
Thin sheets of copper might be an alternative.
 
You dont want copper making some unexpeted connections or your camera will start behaving like a canon!

I mean on the parts that mate together. Not round the lens :)
 
Well the thing won't go off, the adapters are dumb and so are the lenses, no connectors there. I send the Intelligent Sony 100-400 lens back, it was to smart for me :-)
Now I am stuck with a nikkor 50-300 and a vintage nikkor 600 5.6 and some canon lenses.
But I'll try the tape anyway.

If you are putting tape between the flat surface of the adapter and the flat surface of the lens then you are changing the flange focal depth. Not too bad if you eye focua anyway, but these things are supposed to be set within a few microns.
 
I did some google research and found out that the adapter should be 28,5mm (at 20 degrees celcius I guess).
I can measure the adapters with 0.1mm tolerance. So that is a new item on my bucket list. But it might be the connectors that aren't made very well.

Update:
The expensive metabones is the worst one, a nameless 15 euro adapter fits better. I found out that the thickness of the adapter isn't the problem. The lens can rotate 1/2 degree when attached to the adapter. And the lens can slightly moved off-center with all adapters. It might be the lens (only one Nikkor to test at the moment) but I think it is the mount on the adapters that causes the problem. They all are rock solid on the camera side.

Of course but this is the realty of still lens mounts that are not designed to take rotational torque.

For a solid mount PL or FZ (?) are required - here the lens engages with a taper lock.

In 'cheap world' you tape up and move on.

To the OP.

Before I was speed boosting I basically had one $15 adapter on each lens.

Lenses like my 10-24 which doesnt speed boost has its own adapter.

For good results with bigger glass like the 50-300 IMO the lens absolutely needs to be on rods or another solution (like the foot I built :) )
