  1. Big domes are impossible where it is too shallow for them. In this stream I have struggled to use micro domes and other small ports. This year I used the Nauticam EMWL with the 100 degree objective. Even so it was challenge to submerge the port housing the 105mm lens. The location is in the upper inter-tidal. Seawater reaches the base of the sedges growing at the edge at the higher of the two high tides that occur each day during spring tides. These are Pink Salmon, now an invasive species in northern Europe. They have a two-year life cycle so are the "rabbits" of the Salmonidae. This location is about 2km from where I am sitting right now
  2. The score is what one gets from the PowerX Analyzer (no point in using the mili prefix IMHO). It should be the actual capacity but the max it can deliver in current is unknown. I was using the Inons at very low settings -4 and -4.5 so the batteries were not being stressed for recycling but I did shoot a large number of pix. Strobe setting varied as well as lens aperture, either f/18 or f/20, using the EMWL. Still dialing this in for my conditions - ambient light is going down. Mainly was trying to avoid blown highlights as salmon have white parts as well as reflective scales.
  3. I had one eneloop pro die last weekend. It was one of 8 I have been using in two Inon 220s this summer. It registered as HIGH when I put it in my battery analyzer (discussed here before). The other 7 were OK i.e. not HIGH when I analyzed them. With our continuing deluge (so no chance of photography as my local lake is about 1 meter above normal) I decided to put them on the analyzer today - 3 of the remaining 7 were HIGH! I had three good shoots this week (consecutive days with sunshine and just a few clouds) so they did get some heavy use (> 2000 shots/day). As they were fully charged I put them in a three-cell Inon light and the light works. So they are not fully dead but likely not reliable enough for strobes. These pros are dated 2018 so past the 3-year limit. I have 8 more pros. One group of 4 scored 2.2+ Ah while the other 4 scored 2.3+ Ah (about a 50 mAh range for each group) this week (analyzed them after the first one went HIGH). These have not been used for about 2 years so they may not go down as fast if not used. I may switch to them if more of the remaining 4 score HIGH. All 16 were bought at the same time to use with my two original Retras per Retra's recommendation.
  4. I am curious to see similar graphs on the EMWL lenses. Any out there?
  5. Thom Hogan discusses some of this in his two blogs today. See especially towards the end of this one: https://www.zsystemuser.com/nikon-z-system-news-and/what-would-third-party.html of BTW I have been using the Nikon 8-15 via FTZ on my Z6 with no issues. Have not shot it on the Z9 yet; waiting for darkness (only twilight due to spring-summer) and a clear night.
  6. I guess another way of looking at this question is asking what one's criteria are for rejecting or keeping images. I will admit that I do use technical criteria. In the case of my salmon pictures, which quite numerous, I do reject many that are technically proficient and have good composition. I therefore have to have other criteria. One that I use is if I cannot think up a caption other than naming the species or something so simplistic that applies to many of my other salmon shots just as well. I do have pix on my website that have just the species as their caption. I am, however, more critical of my salmon shots. I have tossed many simply because they are boring. On the flip side; if the pic shows an interesting behavior I may keep it even if not technically perfect.
  7. Here is a famous Ansel Adams quote: “There is nothing worse than a sharp image of a fuzzy concept.”
  8. This depends on how many graphs, data tables, etc. one has closely examined looking for patterns, faults, etc. One needs to be analytical. This is a question recommenders are asked of potential graduate students. By the time one has a Ph.D., at least in a science discipline, one should have had a some experience! As well one is trained to be critical, e.g., to do peer review, especially of one's own work.
  9. Over the decades I have observed people reacting to photographs. These observations have included positive remarks of photographs (e.g., photo is great) that I would have immediately rejected if it had been mine, even by well-educated people, e.g., those with Ph.D. degrees (and thus should be a bit more critical). I surmise from this that technical execution far less important than the subject matter. I suspect that non-photographers may not even notice the soft corners of many wide-angle underwater shots and other technical issues.
  10. Z9 3D tracking mode works differently than having the camera find the subject within a designated area (this area is quite variable and is selected separately from detection mode). Doing vids, 3D might be preferred if you are able to see your subject at the start. I tend to have the camera find the subject for me using one of the rectangles (from FW 2.0 on) but pick where in the frame to pick from. For example I picked a narrow horizon box so the AF picked a bird from the row of birds that I selected - keeping the frame over the row if I recomposed. Birds were entering and departing by flight from each row (resting shorebirds). Worked well for that.
  11. Good points. I would be concerned if there was aliasing between the AF and the raster image of the video. For example if there is a moire pattern, how would the eye detect algorithm deal with that? There is a moire pattern when shooting images of my high rez (6K) computer monitor which I do when following instructions on a pdf manual and playing with the settings - great to do on rainy days.
  12. What happens if you find that one of the three is best for video, e.g., the Canon, another of the three is best for stills, e.g., the Nikon, while the third one is best for swimming with (because it is the smallest and should have the smallest housing), e.g., the Sony? Be aware that Nikon just updated the FW for the Z9 yesterday to improve the eye AF. Not using FW 2.1 would invalidate your conclusions regarding AF. I also suspect that using a video image to test AF, tracking, etc.will have issues due to nature of the electronic image. It might be better to go to a public aquarium that has a huge tank and shoot there especially if the room is darkened. Keep in mind you will be shooting through a flat port so best try to be perpendicular. It might need three trips doing one camera at a time unless you like carrying that much around with you.
  13. I found a shot of the scuba set up from my trip to Kauai in 2019. This was my test to make sure both strobes were working prior to a night dive. I left for the dive shop with the float -arm attached since I used short arms for the macro shooting (was able to fit in bag). Bathroom mirror in condo. Also a record that I used a dome port with the 60 Micro Nikkor for the dive! Dive computer strap can be seen. Note that the lights are flopped down (for transport) on YS segments that I forgot to mention above. Inons are not the ball type light (per Adam).The 5 degree light is the wider one! One big advantage of these lights is that the on-off switch is on the rear facing me. The inked in T and W are my attempts to idiot-proof the zoom knob. Also written on the top surface of the housing. Also on my other Seacams. I also have "zoom?" written on the top of the VF bump. This is because I do a lot of remote photography that does not involve using a viewfinder. Yes, the zoom has not been correctly set a few times! The ring rotates when mounting the lens into housing so gets re-set.
  14. I have been using a light that meets these three requirements successfully for my freshwater-blackwater photography lately. Very light (in more ways than one) which is important for this application. I tired a single Inon "pencil light" (3 AAs in a line) but the AF struggled. I am finding that it takes quite a few hours to charge up the single battery. As well one has to push the button a lot to toggle through off, on1, on2, SOS, and back to off. on1 and on2 are two brightness settings. The attached pix provide a better explanation than words (shot with an Ipad mini). I am using the larger diameter Inons for scuba (groups of 3 AAs in a plastic holder). There are bunch of models with longish names. One has a 5 degree beam and the other is wide. The 5 degree light uses 3 AAs whereas the wide one uses 6 in two holders like used in the other one (but just one holder in it). It has a 3100 in the name. There is another model with 1300 in the same place. The rest of the names are identical. Inon sent the 3100 to the US dealer instead of the 1300 (what I had ordered) which has an identical body to the 5 degree light but not as versatile and powerful. With 6 cells it can go through several dives no problem. The 5 degree light is useful for spotting things during the day at modest depths in HI, e.g., 25m, where there is little color. The 3100 etc model is used for focusing. Lots of overhangs and lava tubes so needed on almost all HI dives. I have the two lights attached to a float-arm via a 3-way clamp. The other end of the float-arm attaches to the pole-cam ball in the center of my housings. I remove the two lights with float-arm as a unit for packing the housing on and off the boat (day tripper mode in HI). This makes it possible to close the bag! I mount a dive computer on the float-arm.
  15. Yup - have to spend quite a bit of time on line. Zero people near to me with the same interests as well. No dive shops. No camera stores.... Nonetheless I have had to make the instant decision. This was the case when I ordered the Z6 - within the hour of its introduction. The live stream from Tokyo was at a good time for Alaska - in the evening of the previous day here. I had been in the market for a "sidekick" to my FF housed Nikons which I wanted to take on trips due to the Nikonos lenses (rather than the Canons that I had use up to then and had the 7D2 as my sidekick). I was challenged to decide between the 7200, 7500 and 500 as they each had pros and cons. With the Z6 there was no hesitation.
