  1. @Alex, it’s possible it is the port but I don’t think likely. The port was made specifically for the lens and it butts right up to the glass @Isaac, thanks for the reminder! Shoot I have focusing unit #2 and really don’t want to purchase another one unless the EMWL starts magically working far better than it has!
  2. Interesting, thanks for the reports and info everyone! I'm still getting results that are nowhere remotely this level of sharpness and clarity, and I've been messing about with it for a dozen dives this last week. I'm glad to see that the EMWL is capable of producing good results, but I'm certainly not seeing them with the Nikon 105Z on the Z7II. I'm going to pick up a 105macro in F mount and try that combination with the EMWL and see if that improves the image quality substantially. After using a fisheye, 105 macro along, and with the EMWL, I've had to basically throw out all the EMWL images from this last trip in BC. From what I can tell at this point I'm not really having focus problems so much as the sharpness and clarity are nowhere near the quality of other lens combinations. I'll test the older 105 macro in F mount and report back. Fingers crossed!
  3. I just happened some more interesting information about focus shift due to aperture- apparently it is a phenomenon that happens only with phase detect autofocus. Nikon Z's autofocus in AF-C mode (all I've used so far) is Phase detect, but in AF-S mode it uses a hybrid mode ending with contrast detect. It also has a contrast detect only mode. I'll give the contrast modes a test and see what I can come up with. AF-S is not ideal in a moving underwater situation but it is vastly preferable to manual AF! Hope it works!
  4. Hi everyone, thank you for the excellent and informative responses. Re: Isaac, I have definitely been experiencing back-focusing issues and I am sure it's what Edward has just informed us about as well. It's interesting that it affects the whole variety of setups with focus shift due to aperture. My macro lens, the new Nikon Z 105mm is supposed to have virtually no focus shift due to aperture changes, but then again maybe the EMWL magnifies even minor errors into significant ones. I don't think what I'm seeing is problems due to diffraction really. Almost all of the problem is due to missed focus, after reviewing a hundred of my EMWL images. Very very occasionally I hit focus dead on, and I can see now that it was by accident, as when the lens back-focused and then I drifted into better position by accident. Re: Thomas, nice clean images! I think you're getting good results but I do think that it's because you're helped out by the f22 DOF. But then again perhaps your particular setup is less prone to this focus shift issue? I would think it would be affected even more! I've been hunting all day for possible solutions for my Nikon Z setup, or perhaps with a Canon setup RF setup (I like the EMWL enough in theory to consider particular camera/lens combos), but at the moment the only mirrorless camera that seems to provide the option of autofocusing at whatever aperture you set, especially small apertures (f8+) is the Fuji GFX. My Nikons actually all stop down to f5.6 and focus there, so in theory I could use the EMWL at f5.6 and it would focus correctly, but really f5.6 is quite limiting in terms of depth of field, especially considering what I use the EMWL for- macro distances. f16 would be more like it. Re: Edward's 3 workarounds, only one is actually a workaround- that's using manual focus and focus peaking. And of course it's doable, just a huge bummer given that the promise of using the EMWL to a large degree was the ability to use autofocus. If the focus shift is as sensitive to small changes as it sounds, manual focus might be very difficult as well. The first workaround, (use live view) doesn't really help the problem on mirrorless cameras, and the second (ask the camera to focus at the final aperture) is not actually possible on Nikon, Canon or Sony at the moment. I can really only think of one additional possible workaround- with the lens set at the aperture you would use, and focusing at around the distance you would use, you can preset AF fine tune to correct for the focus shift problem of a particular lens/camera combo, through controlled testing topside (with the EMWL immersed in water through the neoprene sock trick). Even if that works, it would be very restrictive, as it means that your aperture will be locked in at whatever you set the AF fine tune for (although maybe focus shift isn't that much from f11 to f16?), and also your focus distance has to be the same as test conditions as well. That seems like a huge drawback. Any more thoughts? I sure wish we could find a way to make this thing do what it was supposed to. As a professional I think unless I can find a way to make AF more reliable I can't actually use it for work.
  5. Hi all! I've been working with my new EMWL and I love it generally. I’ve been having sharpness issues with the EMWL, though, even when I am shooting with just strobe light, 1/200 at f20 and the 100 degree objective. I haven’t been able to figure out what the cause is. It seems to happen even in good viz (40'+), so I don’t think it’s a problem with muck in between the wet lenses- but i've been diving it in viz from 40' to 15' so it varies. One thing that might be important is that I am using a Saga port adapter specifically for the Nauticam EMWL on my Aquatica housing (yes yes I know). Saga has been producing a number of these and they haven't had any complaints, so probably not the issue. It focuses just fine with this combination so it seems like this shouldn’t be the problem? It's possible it's a focusing problem in general, although even when I can't see focus is spot-on, the critical sharpness just isn't there. I'm including 2 EMWL images, shot at 1/100, f16 and 2 Fisheye images shot at f/5.6. The fisheye is even on a 1.5x teleconverter! Anyone have any ideas? Cheers, Kiliii
  6. Still have this? Interested in the 130 objective lens!
  7. Hi folks, if anyone has a Sea&Sea Internal Correction Lens, in 82mm, please let me know. I'm willing to buy (or rent if that's what it takes) this off anyone that has one. Thanks! Cheers, Kiliii
  8. Hi folks, I have two nearly new YS-D3 lightning strobes for sale. These are the newest strobes from the legendary lineage of the YS-D2J but with much faster recycle time and more. They come with original boxes and accessories. Have only used on half a dozen dives, they are in great shape and fully functional. Never been flooded, no corrosion etc... They have some minor dings as you would imagine with anything that has been actually used on a dive. I treat my gear well and clean them immediately and thoroughly after dives. I have a lot of photo-gear specific feedback on Fredmiranda.com, the high-traffic photography buy/sell forum as Kiliii Yu. $1350 for the pair or $695 each + shipping.
