  1. i use group mode with AF-C only for wide angle when action is involved, e.g. shark shots. IMO it doesn't really work for macro, best is single servo - single focus point and focus field moved to the "sides*. Focus on the eye and release. Others tried also with AFC and 3D-mode, but that did not work for me either; the 3D selected focus point was not stable / remaining enough when moving the frame for recomposing. If I understand you right you want to increase the size of the focus area, i.e. to make the nose and the eye in focus. Imagine a nudy branch diagonal in the frame from top right to bottom left with its head towards the lens. In this example a larger focus area by a group mode would be contradictory since the 4 group mode focus points might randomly select the eye or the nose of the nudi (probably where contrast is higher) and the one or the other might not be in the same focus plane (depending on DoF). Here you want to focus on the eye and be happy when nose is still in focus too. Alternatively instead of focusing on the eye you could use the good old 1/3 rule, namely get the focus point on the first third of the image (1/3 of total distance from close to far) and hope that both nose and eye are in focus. The user manual says that group mode is more for situations when camera is not able to focus in other modes in order to avoid accidentally choosing the background instead of the subject as such. But best way is to try the different mode when shooting underwater and make your own experiences... regards
  2. Hi, if you want the nose and the eye of a subject in focus simultaneously and especially if the subject is diagonal in the frame, it is probably more a question of DoF and less of the focusing method you are using. Your D850 with a larger sensor as the 7200 with a cropped one gets you less DoF. I am shooting a D850 as well and normally I am using single servo /single focus point but moving around the focus field with the left/right/up/down arrows. You could use a smaller aperture for larger DoF e.g. f/16...22 (on diffraction's expense though) and keep primarily the eye of the subject in focus. Other than that I didn't understand what you are trying to achieve, the attachment is missing.
  3. interesting. But better express the numbers in terms of 1/xxx sec, which is easier to read for photographers. That is full power = 1/300 sec ... -6 = 1/10'000 sec. But thanks anyways. juerg
  4. For Sale Nikkor 70-180mm/f4.5-5.6 with Subal Port The only and classic macro zoom lens from Nikon, out of production nowadays. A very convenient macro lens for reproduction up to 1: 0.7x. AF and/or MF. Comes with a Nikon close-up lens type 5, which gives reproduction up till 1:1. Lens is equipped with zoom gear, manual focus gear and auto-to-manual switching gear. Dedicated Subal port for this lens (out of production now). For port type 4 or 3 (currently type for but also for type 3 when mounted port adapter will be removed). Port for auto or manual focus switching underwater is possible. Both lens and port are in mint condition, used only few times since I am more a wide angle shooter. Used a couple of times in Lembeh Straits. Asking for USD 1'500 (plus shipping cost). Payment cash, bank-wire or Paypal possible. Shipping from Switzerland, worldwide shipping possible.
  5. got my new Subal housing for Nikon D850 Special Edition (Nikon 100th anniversary) finally today. Couldn't resist to post some pictures, ordered in February....
  6. I am going to try the 14-24 f/2.8 on a Subal ND850 with a 65mm EXR and a 9" dome later.
  7. there are 2 dedicated new modules from Subal for Canons, but honestly i don't know whether they are any better since I am a Nikon shooter... check it out here: http://www.subal.com/c71c17/Light_Flash/Flash_electronics.aspx
  8. here you go. The middle part is the sucker of the PCB with the blue little battery underneath. Left is the valve housing, right is the final part if the valve which is screwed into the housing port (M14 as for Subal). Pretty neat isn't it?
  9. forgot to mention above: electronics PCB and small battery is inside the valve, outside of the housing
  10. this is the V5 which is specifically made for housings like Subal's with 2 ports nearby, one to use for the Sentinel the other for e.g. a HDMI connector/cable or in my case for a 'manual flash output turning knob'. After some first hand problems works now very well. Just waiting on the new Subal ND850 now. In front is the electronic vacuum pump (powered by an integrated 9 volt standard battery). Sorry for the low quality of the pic (shot on iPhone for ease and quick...)
  11. now when you are saying it, YES it will But I guess the D850 will get me better images than the now already 4 year old D4s...let's see...
  12. its more than just a yellow one, it's a limited edition Nikon 100 years...Subal 30 years... But will it make me a better uw photographer? Probably not...
  13. just changed my current order into this one! Am I crazy or what?
  14. looks like a Ferrari...LOL...or wasn't there red as the corporate color? wondering whether they let you dive with this paint on theses Bahamian waters with the big fish? LOL !
