[QUOTE="dieselnutjob, post: 719706, member: 47318"] The 180mm arrived yesterday, and I'm afraid that I was a bit disappointed. Out of two lenses bought on ebay, two have been f#$£@d. The story of the first one is here [URL]https://nikonites.com/telephoto/43772-used-af-s-70-300-1-4-5-5-6-g-vr-hunting-rattling-autofocus.html[/URL] So. As the seller said, it had dust and fungus in it. What he didn't say is that the focus mechanism is broken. On autofocus it sometimes focus and sometimes doesn't and makes grinding noises. On manual focus the ring grinds and jams. So send it back "item not as described" or take it to bits and see what the problem is? So this is the lens now:- [IMG]http://www.christiantena.net/images/DSC_4642.JPG[/IMG] Well it has always my intention to take it apart and clean it anyway.... Here is photo of when I found the problem:- [IMG]http://www.christiantena.net/images/DSC_4637.JPG[/IMG] You can seen that the cog is not well aligned which is when it jams and slips. Here is the actual part:- [IMG]http://www.christiantena.net/images/DSC_4640.JPG[/IMG] It took a lot of dismantling to get it out but I got there in the end. I will find someone with a lathe who can accurately drill a hole into the end of the shaft. I will find a drill of the right diameter and epoxy it in and then angle grind the drill off to the right length. Fortunately the teeth in the plastic focus cam that this turns seem to have survived.
