[QUOTE="hark, post: 741345, member: 13196"] *sigh* I'm beginning to think @[URL="https://nikonites.com/member-9240-backdoorarts.html"]BackdoorArts[/URL] was right. This combo of the 300mm f/4 PF and the 1.7x TC just doesn't quite cut it. :( Almost everything I shot yesterday was terrific. However, today I used the combo for an eagle on a utility pole that was in the distance, and absolutely everything is very soft with front focusing. The other day I coupled the TC with my 300mm f/4 non-VR lens for an eagle on the same pole. The results were a tad better but nothing impressive. It seems the pairing works better when the subject is closer. But when the subject is further away, somehow it adversely affects the AF system - at least for f/4 lenses. I need to go back to pairing my Nikon 1.4x TC with this 300mm f/4 PF to identify if any AF issues are present. When I used that combo in the past, the results were stellar. It's possible the lens might not be the issue after all. Putting a 1.7x TC on an f/4 lens means it becomes f/6.7. And that might be the problem. I can't believe after all this time of not seeing any eagles then suddenly seeing one twice within a couple days left me with nothing to show for it. :beguiled: [/QUOTE]
