I just bought an AF 105 f2.8 Micro and it has some sort of adapter which I cannot remove from the front of the lens. I knew it had this before I bought it, but I am wondering what it is and how to remove it so I can use filters. I don't seem to recall this being part of any lens I've seen. Thanks.
Set lens to its minimal distance so tube with screw goes out. Keep very tight this tube, so all of turning moments goes on your hand, not on the main body of the lens, to prevent total damage. Now you may use necessary force to unscrew it. Good luck! Dimitri

Whatever it is, I am holding on to it. You never know. I think King Kong must have screwed that on the lens. Wow, I had to reef on it. I threatened it with channel locks and that convinced it to loosen lol.
It looks like a stepping ring (allows the use of larger accessories such as filters and hoods). One thing I find with filters, stepping rings etc is that the harder you try to unscrew them, the tighter they become. This is to do with the manner in which you hold them - if you wrap your hand around the ring and grip it tightly this deforms the ring making it actually grip even tighter on the thread as you try to turn it. Try turning it but gripping it more loosely. Alternatively if this does not work another trick is to place the palm of your hand flat on the front face of the ring and turn the body of the lens with the other hand. If this does not work, try the same with something "grippy" like a mouse mat. Place the lens front down on the mat on a flat surface and press down. Now turn the body of the lens. This holds the ring in place without deforming it and allows it to unscrew more easily - remember you need something to hold the ring steady without deforming it as you turn. I have had to do such things many times with filters which can also sometimes become locked into place. Good luck but I am confident this should work - I have never had a filter locked so tight it will not come off using this technique.
Ah-ha! I thought it was rather odd for a step-up filter adapter. Seemed to have no threads or very few. I am actually thinking about the Sigma ring light, so it could be a nice spare part. I'm just glad I was able to remove it.
Just a note to say that I use a 62mm adapter for my EM-140 ring flash and 105 Micro f/2.8 AF-D Nikkor. It fits at the far end of the fixed barrel.
The advantage is that it takes the weight off of the extending end of the barrel and the associated focusing cams. I believe the Nikon R1 system will do the same and with the R1 this would be particularly beneficial and allow for more lights (and weight) on the adapter.
Along with that, the lights are further back from the subject, somewhat lessening the light angle. That could be good or bad depending on what you are trying to do but having both rings allows for some minor adjustment of the light angle, not otherwise possible.
The 62mm adapter also allows you to put about as much torque on the ring as you want, should it stick, without worrying about damaging the cams
