[QUOTE="hark, post: 775572, member: 13196"] My D500 hasn't been focusing well at all lately despite cleaning its contacts as well as the contacts of my lenses. The thing is it seems almost every time I clean a lens' contacts, there is a small bit of grime that comes off on my Pec Pad. Makes me wonder where it comes from since I haven't used the lens too much between cleanings. So this week I cleaned the contacts inside the D500 yet again. But this time I wrapped a Pec Pad around my finger - DRY not moistened like I've done in the past - and reached to the [B]back[/B] of the body's contacts. There was a flat triangular piece of black stuff between 1/8" to 1/4" in diameter that came off. Afterwards when I tested the D500 with my 80-400mm lens, the difference in sharpness was quite noticeable. But when I attended the falconry event yesterday, I was hesitant to use my D500. So I opted for my first D7200 (which was out of commission for a couple years) along with the 80-400mm. I had far more in focus than I've had in the past when I used the D500. The only problem I experienced was trying to engage the back button while wearing gloves along with glove liners. :beguiled: So Jake @[URL="https://nikonites.com/member-9240-backdoorarts.html"]BackdoorArts[/URL] also attended and was super nice to meet up early to test my D500 and 300mm f/4 PF. He took one photo of a bush, previewed the back, and said '[I]it looks sharp to me[/I].' We chatted a bit then walked over the snowy field to get closer to some bushes. Small birds were flying around, but with my 300mm, they were still pretty far away. I figured it would be a good test to see if there was any improvement to the focus. One issue I've had is getting consistently focused images of birds in flight. I took a handful of test images. Almost everything was in really good focus especially considering how far away they were. Here are a couple of examples. This one is an uncropped image edited with my normal workflow. [ATTACH type="full" width="60%"]369148._xfImport[/ATTACH] Here is a cropped version - which is a rather extensive crop - also using my normal workflow. [ATTACH type="full" width="60%"]369149._xfImport[/ATTACH] And here is another image already cropped quite a bit and edited. The AF might have caught a branch, but it's still FAR superior in sharpness considering the results I've been dealing with for a long time.
