[QUOTE="hark, post: 739883, member: 13196"] So I've used the 300mm PF and the refurbished 1.7x TC with lackluster results. The [I][B]Normal VR[/B][/I] appears to be better than the [I][B]Sport VR[/B][/I]. I also used the lens with a new 1.7x TC with basically the same results. Sometimes the AF is off - front focusing - no matter which TC I use. But [I][B]Sport VR[/B][/I] mostly misses despite the fact that it used to be perfect. Today I mounted the refurbished 1.7x TC on my D750 and 70-200mm f/4 VR lens. I also used it with [I][B]Sport VR[/B][/I]. Everything looks to be in focus with no blur. So I'm assuming it is the lens that is causing my problem. I purchased the lens as preowned. :( Just for fun I might mount this TC on my D500 with my 300mm f/4 non-VR (AF-S) lens and see if it plays nice. ;) Am assuming it will based on what I've found out so far. What I do know is the VR of this 300mm f/4 PF has issues. When using it with [I][B]Normal VR[/B][/I], it's always moved the image up or down in my viewfinder after the image is taken. And that shouldn't happen. But the AF is off with the TC (front focusing). The lens by itself is stellar which is what I don't understand even when using [I][B]Sport VR[/B][/I]. :indecisiveness: [/QUOTE]
