Hi - I was hoping that other Nikon Cafe users who have had this problem might be able to comment. I recently purchased the 105mm Nikkor micro (the "old" version, not the new VR) used, and I am having a dispute with the seller over a bent filter thread. I thought I recall reading some time ago that such a repair is inexpensive - that it's just a matter of a small piece being unscrewed or something along those lines. If anyone out there might know I'd appreciate it. Thanks.
