Mary Doo Posted December 5, 2018 Share Posted December 5, 2018 Result. Nikon warranty included! Expect to see lots of Wednesday Pics with it...;) Amazon update - the lens will arrive on 12/18. Hope it's accurate. Link to comment Share on other sites More sharing options...
Mike Dale Posted December 5, 2018 Share Posted December 5, 2018 Afternoon up on the mountain. D850 + 500PF ISO 640 1/320th f/5.6 4 Link to comment Share on other sites More sharing options...

ilkka_nissila Posted December 6, 2018 Share Posted December 6, 2018 This one is with the D850, 500mm, f/5.6, 1/200s, ISO 22800, EFCS, Qc, VR SPORT. 4 Link to comment Share on other sites More sharing options...
Mike Dale Posted December 6, 2018 Share Posted December 6, 2018 That's amazing, ISO22800 is really good. Noise reduction will clean that up no problem. 1 Link to comment Share on other sites More sharing options...

ilkka_nissila Posted December 7, 2018 Share Posted December 7, 2018 (edited) Is that full frame or a crop? That noise looks very 'big'...:confused: It's a crop from a horizontal frame, so yes, but only slightly cropped in the other dimension. It's with a vivid camera profile which increases the contrast (and noise) a little. I think photo.net in some browsers displays embedded images > 100% - on my Windows laptop it does this, so the images look physically larger than the originally uploaded image, and this does make the noise more apparent (and the image less sharp), but on my Linux desktop, Firefox displays the image at the correct scale. I guess it is a matter of taste, whether some subject movement blur with less noise is preferable to a sharp image with more noise. I prefer the subject to be sharp and don't mind the noise in this case. I don't normally use the D850 at such high ISO settings, so it comes as a surprise that the image came out as well as it did. I think it's because the blue channel is normally the noisiest one and early morning natural light contains a lot of blue, so this makes it possible to achieve a better result than would be obtained in artificial warm light at similar ISO values.

mike_halliwell Posted December 7, 2018 Share Posted December 7, 2018 (edited) preferable to a sharp image with more noise Sharp every time for me, no exceptions! You can manually 'blur' noise in the background areas. You don't really see it on the bird. I occasionally corrected a tiny bit of linear subject movement, but most birds I've shot that way aren't very linear! I guess you could tinker with the RAW, but it's the image's IQ with the lens wide open, that's the key...:) I'm looking at it on a Windows 7 machine via Chrome.

Andrew Garrard Posted December 7, 2018 Share Posted December 7, 2018 That's amazing, ISO22800 is really good. Noise reduction will clean that up no problem. I've been really impressed with the high ISO performance on the D850, even if it only measures a stop or so better than the D810. I've found that DxO Prime sometimes doesn't help as much as you'd think, though - it gets very blocky very quickly in trying to remove all the noise from something at high ISO, and starts looking unnatural. Your suggestion of manually blurring out the background would be a good workaround (and also, in my experience, a way to simulate a much wider aperture...)

Mike Dale Posted December 7, 2018 Share Posted December 7, 2018 illkka gave me permission to do a Topaz AI Clear noise reduction on his Blackbird image. For ISO 228800 I think it came out rather nicely. This took all of 30 seconds. Open Click Done. 2 Link to comment Share on other sites More sharing options...
mike_halliwell Posted December 7, 2018 Share Posted December 7, 2018 his Blackbird image Smooth, literally.........:) Oh, and I think Mike might have added an extra ZERO to the ISO Number...;) Link to comment Share on other sites More sharing options...
Mike Dale Posted December 7, 2018 Share Posted December 7, 2018 Yeah, sorry about that. One too many 8’s, should have been 22800. 1 Link to comment Share on other sites More sharing options...
mike_halliwell Posted December 7, 2018 Share Posted December 7, 2018 Still pretty darn impressive....:cool: Any detail salvageable in the 'under tail' region? Just asking...;) Link to comment Share on other sites More sharing options...
Andrew Garrard Posted December 7, 2018 Share Posted December 7, 2018 Thanks for sharing, Mike(D). I was already vaguely looking at the Topaz AI gigapixel thing, but that's standalone. I should probably experiment and see how their newer stuff compares against DxO PRIME - I'm currently a bit confused because they have "A.I. Clear", "Reduce noise" and "Topaz DeNoise" - and I'm far from clear how they compare. (As far as I can tell only the first one is AI based, but I'm not show how that affects the flexibility the others might have.) I'm prepared at least to try out the free trial, but installing all three seems overkill! AI denoising certainly seems to work well - it's being used as an integral part of the real-time ray tracing stuff which NVIDIA et al. have been pushing recently, and the results are pretty noising without it. There have been some impressive results in SIGGRAPH. Of course, the danger with anything like this is that it's producing a "plausible image" rather than a canonical interpretation of the input, so every now and again you'll get something weird turn up, but that doesn't make it useful 99% of the time (or with suitable supervision).

Just asking...;) I doubt it, it looks a bit too black. All I did to ilkka’s image was download, opened in Topaz Studio selected AI Clear clicked using the defaults and saved as Blackbird then reposted it.

The thing I like about AI Clear is that it’s extremely simple. The only other Topaz program I use is Remask which is pretty simple too. I don’t know about any of their other apps.

I'll see if I can get a clearer explanation out of their sales support. Link to comment Share on other sites More sharing options...
ShunCheung Posted December 10, 2018 Author Share Posted December 10, 2018 Over the weekend I talked to a Nikon rep. The 500mm/f5.6 PF is indeed in very short supply. For whatever it is worth, he pointed out that it takes seven months (yes, 7 months) to manufacture the large PF element, and that is why supply is slow.

mike_halliwell Posted December 11, 2018 Share Posted December 11, 2018 it takes seven months (yes, 7 months) to manufacture the large PF element If that's from mining the right 'sand', making the correct mixture and melt, cooling and annealing, slicing it, cutting out the hockey pucks, centering etc etc, well yes maybe. But it cannot be over 200 days or 4800 hours of lens grinding! 1 Link to comment Share on other sites More sharing options...
ilkka_nissila Posted December 12, 2018 Share Posted December 12, 2018 I don't know how Nikon manufacture their PF elements, but since they make lithography equipment, it would be my first guess that they'd use that to make diffractive optics elements, too.

ilkka_nissila Posted December 22, 2018 Share Posted December 22, 2018 (At least theoretically) the darkest day of the year, snowing lightly, windy, -7C on the shore of Lauttasaari, Helsinki. D850, 500/5.6 PF, f/5.6, 1/250s, ISO 2000. 4 Link to comment Share on other sites More sharing options...
Mary Doo Posted December 22, 2018 Share Posted December 22, 2018 I received my 500mm pf from Amazon a few days ago. I finally took it out for a test run today. It's pretty good. A keeper. Nikon D500 camera with 500mm f/5.6 PF lens. 1/800s; f/5.6; ISO 1250 3 Link to comment Share on other sites More sharing options...
Mary Doo Posted March 24, 2019 Share Posted March 24, 2019 This is an excellent lens. However, I may be selling mine as I find that it stays in the bag most of the time as I mostly use my Olympus mirrorless lenses now. If anyone wants it for the same price I bought it ($100 less than list price), please let me know. Comes complete with everything in the box plus arca-swiss foot. Shun, if this is considered advertising, please feel free to delete this post. I am doing this only because the waiting list is still long and people in this forum understand its value.

Mary Doo Posted March 24, 2019 Share Posted March 24, 2019 selling mine as I find that it stays in the bag most of the time Thinking perhaps I should sell it for $200 below list as I did take it to Yellowstone. It gave me awesome photos of elk in snow. Just checked, it's in impeccable condition. Link to comment Share on other sites More sharing options...
ShunCheung Posted March 24, 2019 Author Share Posted March 24, 2019 Mary, you should get a Z6 or Z7 body and try FX mirrorless. :cool: 2 Link to comment Share on other sites More sharing options...
