I use a Nikon 1.4x teleconverter with my 300mm F/4 lens for wildlife sessions and I've noticed that it is very easy to nudge the teleconverter's lever and this would be disastrous in the field (or anywhere else, for that matter.) Is there any way to conveniently and cleanly prevent movement of this button until it is desired?
I've searched the forums with no success but a brief perusal of Lens Coat's site shows a neoprene cover for the converters and I suppose that if one were to cover the button with this that some degree of protection would be given. Does anyone have any tips for this problem.
I don't think this is particularly common. The question hasn't come up more than once or twice in quite a few years around here. I have one of these TCs and commonly use the TC-20eIII also and haven't ever noticed the problem, even though I've noticed that some bodies are easier than others to surprisingly use the lens release button and in particular have noticed that it's really easy to confuse the lens release with the rotation button on the 24/f3.5 PC-E. I suspect that this why you've had no success with searches...

I'm not referring to the camera body lens release button but the lens release wedge shaped device on the teleconverter. An inadvertant push back on this will set the lens free. It looks to me like a collar would work to prevent this from happening, as would a few strongish well placed rubber bands. I am trying to avoid a Rube situation though...
I have four Nikkor TC's including both versions of the TC-20E and never had a problem inadvertantly releasing the lens. Have you done it in the past or is it just a concern in the back of your head? I think using a lens coat might make it easier to inadvertantly press the release button. I have gotten into the practice of verifying that the lens is securely mounted to the body for the same peace of mind that it sounds like you are looking for. Better safe than sorry! Good Luck and Enjoy your Nikons!
I have the same lens as you, and am using it with a kenko Pro DGX 1.4 converter. Just had the exact problem you are talking about. Somehow my lens became detached from the converter and fell to the ground. I was in a state of shock. As luck would have it no major demaged occured. Some marks on the collar and on the lens hood. I can't figure out what happened. Don't know if I pressed to converter button by mistake when I picked up my camera and released the lens. One way or another I'm really worried that this could happen again.

I've not done it. Just noticed that it's very easy to do and am thinking to prevent it. My level of photography is such that I need to remove extraneous items from my routine

Perusing the reviews of the lens coat item on B&H led to a statement by one of the reviewers that the neoprene must be pushed out of the way before using the button. I think that a strong push will activate the button. The button travels back toward the camera body and any method used to make this more difficult would be of merit, in my mind. Since one usually attaches the lens to the converter and then the assembly to the camera a collar used to restrict backward travel of the release button would seem to be the ideal solution.
To OldPro - glad no major damage was done. I am able to understand the shock factor....
