Alaun Posted December 1, 2018 Share Posted December 1, 2018 Cadmium wanted some pictures with this combination (see clip filter thread) and today, there was a tiny bit of sun So combination is the Nikon 8-15 fish with a Kodak Wratten Gel filter 88A In general, there is no hot spot, but with a lot of direct light (sun) you can induce a slight flare.

dabateman Posted December 2, 2018 Share Posted December 2, 2018 Alaun,These look great. Can you post one straight out of camera, and remind me what camera you have. I am interested in the field coverage.Thank you, Update, 2 seconds in a Google search and got my answer. Full circle at 8mm and full coverage at 15mm. That's great. I will have to look out for this lens in the future. Would be fun on my Df. David Link to comment
Cadmium Posted December 2, 2018 Share Posted December 2, 2018 Werner, Thank you for these!I can't tell about any hot spot. Lets see what Bob thinks.The photos are great.I especially like #9, #10, and #13. It is also nice to see the mix of 8mm and 15mm shots. Nikon made an 8mm fisheye, the one I have, and also a 15mm f/3.5 and also f/5.8 (I think), I don't have the 15mm lenses, but the photos I have seen of those are similar to your 15mm zoomed shots here. Thanks again. Link to comment
bobfriedman Posted December 2, 2018 Share Posted December 2, 2018 Steve: there is curvature in the 15mm shots since they are not rectilinear like the Nikkor 15mm f/5.6 QD.C in the first set I see hot spot flare and the first three don't look sharp to my eye. in the second set the monochrome images are quite sharp and came out quite nice - maybe I should take a trip there for my own shots?? the color images are hard to discern for hotspots.. second one probably. the last set may have a hot spot in the first - third image, albeit faint. all look sharp. I would use live view with this lens and check the image directly in IR from the sensor and orient the lens to mitigate any hot spot flaring if possible.. I know this is a difficult task with a lens that sees 360x180. also liveview allows critical focus to compensate for any focus shift. Link to comment
Alaun Posted December 2, 2018 Author Share Posted December 2, 2018 Well analysed, Bob! :) I do a kind of blind shooting. I neither used the view finder (it is black) nor live view. I learned and practiced that when I started with the D70.As the AF-L button on the back is programmed for AF, it happens that I hit that button unintentional, just out of normal habit. But with the 8-15, the focus often stops very close then, though the lens seems directed into the far. All the pictures, which are sharp are manually focused :) using the scale on the lens.

bobfriedman Posted December 2, 2018 Share Posted December 2, 2018 I would use live view.... I use a hoodman loupe for all my modified cams http://www.pbase.com/bobfriedman/image/168053563 Link to comment
Alaun Posted December 2, 2018 Author Share Posted December 2, 2018 That thing looks nice. Probably very useful, when it is bright outside. I have to google it. May be even more useful for UV?! With the fish, I often use positions close to the ground or high up over my head (e.g. the last two pictures), which would have been impossible with using a finder Link to comment
Alaun Posted December 2, 2018 Author Share Posted December 2, 2018 That is a loupe for a 5.5" screen? Link to comment

bobfriedman Posted December 2, 2018 Share Posted December 2, 2018 using something like this hoodman will get you a lot more keepers! Link to comment
Cadmium Posted December 3, 2018 Share Posted December 3, 2018 I have both Hoodman and Zacuto.Personally I prefer the Zacuto Z-Finder best. They have different sizes to fit different LCD sizes, both oval and round padded eye cups available (I prefer the round style myself), etc....https://www.zacuto.c...dslr-viewfinder Link to comment
Andrea B. Posted January 2, 2019 Share Posted January 2, 2019 Hi Werner!Post #2, Photo #2 -- That is so cool! It is a Photo-of-the-Month candidate somewhere. Or Photo-of-the-Year. It is otherworldy for sure. (Although I note that this Other World still has cars. Smile.) Post #3, Photo #2 -- What a great photo. Love this one also. Link to comment
Alaun Posted April 18, 2019 Author Share Posted April 18, 2019 Thanks Andrea! (didn't saw your comment until now) Bob and Steve, thanks for the proposal with the Hoodman and Zacuto.I tested both and will keep the Zacuto. But the camera then is quite a big machine!
