[QUOTE="hark, post: 740026, member: 13196"] The jury is still out on my refurbished 1.7x TC and 300mm f/4 PF lens. Yesterday's outing with the non-VR 300mm coupled with the TC went well but was very heavy for the tendonitis in my hand. So last night I pulled out the 300mm f/4 PF once again. Back when I inspected both the TC and the lens, I cleaned the contacts first by using a rocket blower, then an eraser, then a microfiber cloth. Nothing changed. Last night when I pulled out the lens, once again I inspected the contacts. This time there were a few very short pieces of fibers somehow attached to one of the contacts. They must have gotten loose when the lens was removed from the TC. But they weren't completely loose - they were caught around the base of the one contact. Carefully I removed them and became hopeful that [I][B]maybe[/B][/I] something would change. @[URL="https://nikonites.com/member-37799-needa.html"]Needa[/URL] will be proud! Lol. So today I photographed more geese. First couple of images were without VR. All images today had a shutter speed of 1/1600". Not bad on the non-VR pics. Then I switched it to Normal VR. Much to my surprise, the consecutive images didn't jump in the viewfinder like they did every time in the past since I've owned this lens. ::what:: Wow, that surprised me. Then I switched it to Sport VR. Scrutinizing those on my PC, almost every one of them is in focus with just a few being the slightest bit soft (am attributing those to AF-C because I've always had a few that weren't totally sharp). :cool: But those slightly soft ones certainly were nothing like I was getting when this problem began. More testing will be done - tomorrow looks to be a decent day weather-wise. Today they called for rain but was only overcast while I was out. The real test will be putting my shutter speed back down to 1/1000". Staying hopeful! :encouragement: [/QUOTE]
