  1. Interesting case. Maybe you could test with and without the filter at a couple of focus lengths and different f stops. At least at the extremes. Then check if you can see it in the viewfinder/live screen. If that's the case maybe test a couple of filters (could be used of course) at a shop or some other outlet and see if there are any that give a perfect image. (= as if there's no filter.) I have no idea how it will show on a Siemens star, but I'm pretty sure it will be visible. Good Siemens stars here. I would print 3 and tape them each to a stick and put them in the scene you normally use. One at the point you normally focus on and two further away. Mark the distances so you can repeat it somewhere else like outside a shop. wim
  2. There's even a report from 1999 on film. So it seems no sensor related problem. The effect seems greater at longer lenses and smaller sensors though. So far no real explanation. wim
  3. The box should have a label like the image on this page: https://en.wikipedia.org/wiki/Bintje It could well be this variety btw. Google Images. wim
  4. I have been reading up on this problem for a while now and I have seen reports as early as 2007 of people who have fixed it by omitting the filter. Also good quality filters are being reported as problematic. Keywords I have used so far: diagonal; banding; bokeh; filter. No real explanation yet. Other than: told you not to use filters. So far only 1 solutions: don't use a filter. Here's a nice write up about bokeh. wim
  5. Here you go! From today's inbox: https://store.hasselblad.com/products/907x-50c Just €6,590.00 for 50 megapixel. But the same Hasselblad crop as always. A sort of 6x6 APS - 43.8 x 32.9 mm. Let's coin the phrase APS-H here. 😁 Oh no, that's already been taken by Sigma for the SD Quattro. 🤦‍♂️ wim

  7. Well spotted! So Gen, it may not need a repair after all. Or it may, but that wouldn't resolve the problem. I would do some testing with everything manual on a sturdy tripod. Use the self timer or a remote. wim
  8. If you're happy with the image quality, the successor was better in all respects. But it's going at twice the price used. The old ones go from 450 US upwards and the new versions from 900 US. The old ones are abundant in Japan. Not checked the new version though. The difference is easy to spot: the old one has an aperture ring; in the new one the aperture is set on the body. Here's a side by side image. Here's the side by side specs on dpreview. Here's the dxo lens database which alas is not being maintained as it used to be. They're mainly into phones now I guess. But all relevant lenses are still in there. You have to check current street prices yourself of course. Sharpness is the relevant column. Set things like mount and maybe check something like the super telephoto box. It is very useful to see the whole field though. Especially to see where the lenses you like most are sitting. That gives you a ball park of where to look. No use looking for a quality that's far below or beyond you're using now. For US readers: but do keep an eye out for the left field. In this case: maybe try the outlier Tamron SP 150-600mm which may be just the ticket. Quicker but even softer than the older Nikkor, however: 600mm! So you will need some good PP skills. The price used will be nearer to the old Nikkor. (The Northrups about it on youtube) I have a small collection of 400 to 600mm lenses because I got inspired by Andreas Feininger at one point: (This would probably be the equivalent of a 1200 to 1500mm.) I have converted some old manual lenses as well, and yes it all works. But as soon as things start to move, it's a whole lot more difficult. And modern quality is a lot better than those sixties and seventies lenses. Feininger got around it by shooting 4x5. His use of long lenses was all about perspective btw. (not my picture) Mine at 1200mm Edit: in the left picture you can see both the windmill and the same church tower. After renting some modern long lenses and working with a lot less forgiving Sony, I've stopped f.. ehhm tinkering around with that old glass. But hey it might work for you. wim
  9. Hmm your example image was at 5.6 and 400mm, so wide open. It could not be the shape of the aperture, but it could be something else. Aperture blades don't weigh a thing. Stuff that rattles loose is either heavy or not fixed. If you have the VR on, can you hear the unit working if you put your ear to where it sits in the lens, which is somewhere in the middle. If you have the lens off the camera and you hold the lens horizontally; then flip it over, can you hear something shifting inside? Could there be something else flying around inside? Take a small flashlight and look through the lens from either side. Open and close the aperture, see if there's a blade missing that could be sticking out somewhere. Or if something else is moving around there or is sticking in from the side. (Nikkors still have a mechanical coupling for the aperture I believe. just in case, here you can see someone operating it around 0.45.) My best guess is a dislodged VR unit though. BTW is yours the Nikkor 80-400mm VRII or the original mk1? The serial number suggests it's quite an early mk1. The general consensus seems to be the original is not worth repairing, with the newer one being not very expensive plus a lot better. Operating on one yourself is not for the faint of heart. wim
  10. The real thing. But then this happens. Maybe this should be in the other thread. The price certainly does. Much more on FB. wim
  11. #StayHomewithLeica: Jim Marshall - Show Me the Picture with Amelia Davis 2 hours on youtube. wim
  12. You're welcome! I only looked at FB afterwards. I just checked the image, mainly because I thought wt* is that? After finding the name I combined that with Audubon Zoo. Not been there btw, but I know where it is. As we speak I'm wandering through it - with Google Streetview. 😂 Not seen the bird yet. wim
  13. Spectacular! Sunbittern. https://en.wikipedia.org/wiki/Sunbittern wim edit: just found these on FB and on OnlineZoo.
  14. Those exist. Slightly more boxy and called Sony RX100. 😂 I still have my XA. People have adapted the lens to digital. I know because I have toyed with the idea also. (1; 2) wim
