  1. I used dslr and switched to mirrorless. I think dslr ovf has more advantages than mirrorless evf. But the reason I use a mirrorless is that I use contact lenses because I have poor eyesight. Contact lenses can fall out if i close one eye. This is not the case because it is currently filmed through an external screen. my new planning to add an underwater monitor now.
  2. I'm using xtar vc8. Charge the usb-c port use and 18650 lithium rechargeable battery and aa rechargeable battery. In the vc8 I use, port 4 measures a little higher voltage. So the lithium rechargeable battery does not use slot 4. However, the Panasonic Eneloop Ni-MH battery charges. The charging algorithm of lithium rechargeable batteries buffers with voltage, so inaccurate slot 4 is not used. The charging algorithm of the Ni-mh rechargeable battery stops charging by measuring the voltage drop after full charge. Therefore, although the voltage measurement is inaccurate, it is believed that slot 4 buffers Ni-mh. There is a disadvantage to slot 4( slot 7), but I have been using it steadily for usb-c high-speed charging and convenience. And it's cheap. Of course, it is not clear whether these shortcomings are just my product's problem.
  3. The important point that others say is that cameras do not come first in underwater photography equipment, but housing setting first.
  4. HelloI own something that is not the same maker's housing, but I had a similar problem.In my housing, the right arrow key AE-L button did not work well, and in a vacuum state, four buttons and the front wheel did not work.My housing solved the problem through dealer service.The four buttons were adjusted by adding a washer, and the problem was solved by adjusting the position of the front wheel contact.Maybe you will solve the problem with a little adjustment when you receive the service.I am using z6mark1. I know that mark2 uses dual memory to have two memory cards on the right side of 2 mm, which is thicker.Among the housings of several makers, isotta is the only housing that can be used together with mark1 and mark2. Perhaps it will work well if you receive the manufacturer's service and adjust the housing controller. I hope your problem will be solved well.
  5. Hi.I'm not an expert, but a lot of content in the forum shows that housing is not an accessory to underwater photography. The camera is an accessory to the housing.If you want to use Sony A1's current highest quality expensive camera as an accessory for underwater photography, I think a good quality housing and proper setting will produce good photography results.Before I knew this forum, I used a 14-24 lens and an 8-inch dome port for the first full-frame camera Nikon d800 dslr, but the quality was not good. Compared to the existing small compact camera underwater photographs, it was difficult to find good points in the photographic results and I was disappointed.Later, I read and studied the forum, used Sigma 15 fish eyes, and improved the quality of the picture. If I had known Wet Pixel Forum before purchasing equipment, I wouldn't have made a double investment.Currently, it is used underwater as a full-frame Nikon mirrorless.If you use an expensive high-end beast-like camera like Sony a1, I think the camera will perform only when you use a dome port suitable for housing and setting for good image quality.
  6. I use 8-15mm, ftz adapter, z6. Nikon is known to have lower auto-focusing performance than Canon or Sony.However, in a wide angle, I have no regrets in the environment I use.Properly, if you raise the aperture, the quality is clear from the center to the periphery. Usually, aperture f11 is used a lot.It is more comfortable to film than the d800 I used before.However, the f mount 105mm feels slow.I'm curious about the performance of the new 105mm z-mount. If there is a review on the expansion soon, it will change to 105mm z-mount.
  7. Thank you for your information.I am also using Z Mount, but I am using FTZ Mount 8-15mm fish eye lens and 105mm macro lens.I was very interested in the combination of 14-30mm F4 lens and SEA&SEA filter, but I was hesitating because there was no review.I wonder the result of the picture of the higher aperture.
  8. It was not the same product, but the distance between the screws of the aquatica housing handle was wide, making it impossible to mount the inon lanyard adapter.
  9. The FF settings I have...D800 sigma 15 and Z6, 8-15 weigh 8kg to 9kg.The arms are 5 + 8 inches long and the strobe uses z240 or z330.The arm has a buoyancy of 10 bar.The dome is an 8-inch acrylic dome port in both settings with a slight weight added to the front.The weight of my DSLR and mirrorless is not much different.
  10. I also have an experience of having a problem communicating mail with Aquatica.I got a reply, but I was rather confused by the inaccurate answer.For example, the newly purchased housing accessories were different in shape from the manual and could not be installed. This is the connection accessory of the lens adapter and the button that detaches the lens.When I inquired via email, they said there was no problem, but the service center put it together again and solved the problem.The service center said the assembly of the accessories was reversed.I understand the frustration of this forum creator.
  11. If I take a picture at 8mm with the extension ring I'm currently using, there will be no vignetting if I remove the lens hood and dome hood. Nikon 8-15 lenses vary in circular size depending on focal distance. I didn't see the vignetting in either focus.
  12. Hello. I'm writing again to wrap up this topic. aquatica say, Both are good for image quality, but with extended rings you can get better results. As a result, the Aquatica portchart does not sound like the optimal extension for the lens. Aquatica recommended the shortest extension ring, but fortunately, the dealer had several expansion rings in stock, so we were able to test them. As Aquatica said, instead of the shortest extension ring, I buy a longer 21.5mm product number 48463 ring. I buy an extension ring that is 5mm longer than Aquatica recommended. 21.5mm was also non-vinetting, and it has quite a spare length. It is difficult for me to identify the difference in quality between the extension ring recommended by Aquatica and the 21.5mm I chose. I blame Aquatica for having customers check the extension ring themselves. Port Issues Quality Issues Assembly Issues it's the worst for me, scuba diving and buying a fourth house for 15 years.
  13. Hello Adam.... I needed some advice English is not my first language, so please understand if there is word bad.I already wrote it, but you are my big fan. Your writing and video helped me a lot with the theory of underwater photography.Aquatica sent me messages first and exchanged a few emails.I believe that button manipulation problems will be corrected.As you may have already read, it's about the 8-15 lens extension.At first, I received an e-mail from Aquatica that they would talk to the engineer about the 8-15 lens and let me know. The next e-mail I've received is... "For the 8-15 lens,we have some customers using without an extension ring and some use with one of our shirsest rings,both getting good results. For sure with an extension ring you will need to remove the dome shade,so you will not get vignetting. Next week I do have an order shipping to my dealer in Korea,in the shipment we can include this short extension ring,and you can give it a try." "shirsest" is probably a typo. shortest So I compared all the expansion rings of other brands. Of course, I expect the difference in distance from the sensor to be different for each brand, but just for my reference.First of all, the Canon 8-15 and Nikon 8-15 use the same extension ring for most brands (Nauticam has 10mm longer Canon).But I think Aquatica's extension ring is probably the shortest 48456 (16.5mm/65in).By the way, there is a port chart in Aquatica to use 48463 (21.5mm/.82inch) for Canon 8-15 lenses.So it's the weekend and it's dawn in Canada, so you won't get a reply, but I sent you an e-mail saying I want to test two, 48456 (16.5mm) and 48463 (21.5mm) if possible. But there are some questions here.1. As Aquatica said, if vignetting occurs when using a short extension ring at 15mm, we should use it without an extension ring. Diving would be hard without a dome hood. 2. According to the Nikon 8-15 lens review, I saw a post in your article that the vignetting got worse because of the expansion ring. July 6, 2017https://wetpixel.com/forums/index.php?/topic/60171-nikon-8-15mm-in-the-house/ Could you share your opinion on this? 3. For reference, compared to Aquatika's Canon Lens Chart, Canon 8-15 does not have any benning for the dome hood, but I actually do not understand if Nikon expects that even 5 mm short expansion rings will cause vignetting.I want you to let me know your opinion. Thanks a lot.And I always watch your posts and YouTube well. Thank you.
  14. It's a little different from the extension ring, but I think I found the cause of the button failure myself.The ok button, down button and right button, which are not working as shown in the picture, are slightly higher on the camera body, and the rear connections of the housing are made lower to suit the camera height.With the camera mounted on the housing, pull the lower part of the camera a little bit with force to operate the aperture wheel normally.And if you infer that the upward button always works, it seems that the bottom of the camera body goes deeper into the housing than the designed one.Maybe it's a camera alignment problem. I think the lower part of the camera body goes in a bit more than the angle designed in the aquatica housing. However, when I close the back plate of the housing, the camera is pushed back, so I couldn't check if the button was working properly.I'm going to deliver this to Aquatica.
  15. thanks you Tim I started talking to Aquatica by e-mail.I'm not sure, but I think Aquatica housing is around 20mm with the naked eye.But it's a little too much for an individual like me to measure. Perhaps too long an extension ring will cause vignetting. I think Aquatica will teach me a good solution. First of all, I will wait while solving the button operation problem.
