  1. Hi Folks,


    I am trying to use my Canon 100mm f/2.8 USM (not L) plus the Aquatica Macro port with the focus knob below the port and not on the left side as usual, but for unknown reason the gear on the port doesn't touch the lens gear. It looks like the camera isn't centered inside the housing/port.


    Does anyone tried that ? had the same issue ?


    My idea to use that is make my job easy to use manual focus.




  2. Hi Luiz,


    I spent couple years shooting with 5dmk2 without any TTL because the old Mathias TTL converter that I had working with my 5d didn't work with 5dmk2. I really missed that feature for few months, mainly for fish behavior, but I we are capable to adapt and change our mind to shoot without that making the adjustments manually.


    Since Feb this year I upgraded to 5dmk3 on Aquatica housing and started to use the YS TTL Converter/C with couple YS120. I am really glad to have it back. It is very reliable.


    The only cons I have about that TTL converter is related with appertures over f/22 where we need to increase the light compensation using the dial in the converter, but it doesn't vary, I just got in mind the compensation for f/22, f/25 and f/32 and it became automatically for me.

  3. I made my decision three months ago to Aquatica for my 5mk3. I didn't dive with Nauticam, but had the opportunity to get both it in hands before decide. The Nauticam looks nice, had lot of engineering onboard, but I felt Aquatica more solid/strong and the simplicity of the commands inside made me believe it should be more reliable and easy to repair.


    But it was my perception, I think you should locate a near reseller and taste both housings...


    Cheers. Fabio.

  4. Thanks for the response. I didn't really think you'd be able to see vignetting with a macro and a flat port, but I didn't consider the close-up diopter effect.


    Under one week to my first chance to try mine out, and with a homemade fiber lightpipe ring flash setup. :)

    I just saw vignetting when use sigma in the flat port with Aquatica close-up holder. that holder fill lot of area in the front of the flat port.


    Please educate me on why extension matters behind a flat port?



    I did tests with Sigma macro lens in the past and I found couple issues about their extension movement:


    1) you need to have a bit more long extension ring that will force you to get the port more close to the subjects. If you use a wet close-up filter for super macro, you will probably need to touch the subject. Some critters doesn't allow that, making you job hard to get a picture.


    2) Due the needs to have more distance between the lens and port glass you should have some vignetting when the lens is retracted and you use a wet close-up filter like subsee or aquatica.



  6. Thanks CP,


    as I have used this lens many times for topside photos due their flexibility, some times when need to carry less equipment, it could be an option for some trips and it share the same extension ring then 24-70mm that is in my wish list for next months, then I will not loose the investment on the extension ring.


    Based on your photo I can see it works better then I was expecting. Probably it will not work well all the way, but from should work from 24 to 70...


    Thanks again.

  7. Hi folks


    I tried to buy a new Sea & Sea TTL YS Converter/C (Product No.50118), but I heard from almost resellers that it was discontinued. After expend some time googling I found another in some online stores with different name:


    Sea & Sea TTL Converter III for Canon (Product No.50114)




    Based on the name, it looks like a new version, but the part# shows different, don't know if it makes sense.


    Does anyone knows if this version III will do the same job as than the discontinued version ?




  8. I also use case 1 without issues.. for moving subjects Al Servo, never tried Case 5.. I will try that next week to see the behavior..


    Just a note: The 61 point of focus depends on the lens you are using, not all are enabled for every lenses. You can find that information on the manual, so there is a list of lenses separated by group with the enabled points for each one.

  9. I started to use that on Aquatica housing last week.. Based on my land tests and also in the swimming pool It worked very well with my canon wired to couple YS-120 strobes... The only issue I found was for small apertures over f/22 where it usually shows under exposures, so I needed to compensate using the TTL compensation dial on this converter.


    I think it should works on Nautican too if you have the nikonos with 5 pin wired to the bulk head.


    good luck.

  10. Hi folks,

    I am an Aquantica+utralight user, so I have a focus light support from Ultralight and I am trying to attach this part on the top of my 5dmk2 housing through a ball head using the hole on the top of my housing, but I didn't see any ULCS part that fit this hole.


    does anyone knows what is the part number of this ball head ?


    Here is attached a picture about the hole on the top.
