Sony AX100 autofocus problem

22 June 2015 - 05:01 AM

Sometimes when I am using autofocus with the Sony FDR-AX100 and a flat port on the Gates housing, autofocus doesn't work!


When looking at the clips after the dive, the subject can occupy 1/3 of the screen, and be nicely centered, and it is out of focus; the background is in focus even if it is relatively far away! The contrast seems to be sufficient; the camera apparently does not respond.


This seems to have happened after the latest firmware update to V3.0.


There seems to be more focus "hunting" underwater since the update. Topside, the problem does not seem to happen...


Anyone have any thoughts about this?


All help appreciated,



4K screen capture -> nudibranch eggs

25 May 2015 - 04:19 AM

Here's a screen capture of nudis and their eggs from the Blue Heron Bridge, Phil Foster State Park, Riviera Beach, Florida USA:

The Nudibranchs are Flabellina Dushia (thanks to Anne D. for the ID!) and are about 5/8" (1.6cm) in length.


I used the new ReefNet diopter adapter and a +10 SubSee diopter on the Gates AX100 housing. The Sony AX100 has firmware v3.


The tiny spiral of eggs is clearly visible, making the individual sand grains look like large boulders!


Ask me if I'm sold on 4K LOL




PS: The (absolutely horrible)  video is on Youtube at https://youtu.be/1NtMt7f0CjU I will get better, I promise - it was my first try at using a diopter...

Sony AX100 firmware v3.00 released

14 March 2015 - 07:44 AM

I just updated my AX100 to Sony firmware release V3.00


I will test it sometime next month I hope.


The major updates Sony claims are an increase in the data rate from 60mbps to 100mbps and improved autofocus. When I put the camera into the 100mbps data rate setting it informed me stills are not available. Not a big deal to me...


If you want to update, go here: http://esupport.sony...up_id=3#prepcam


Here's Sony's short list of the firmware V3.00 update contents:



What Does This Do?
This utility updates the system firmware for Mac® and provides the following benefits:

Improvements over previous versions:

  • Adds XAVC S 4K 100Mbps
  • Adds capability to capture still pictures from video contents shot by XAVC S
  • Improves trimming playback
  • Improves auto focus performance
    • Focus tracking performance on a person


After the update I switched to a new, blank SD card - there's no mention that there's any incompatibility between the old and new file formats, but I didn't want to take a chance on losing anything already on the previous card.


The new data rate definitely eats the card space quicker.





Sony AX100 question

10 December 2014 - 06:12 PM

I have a Sony AX100 & Gates housing. In trying to learn the camera I have been blessed with the following error message I find totally baffling.


If I press the PROGRAM AE button to try to get it into that mode, I get


"Set the adjustment for brightness to auto."


I am normally fairly opaque, but this time maybe it has gone over the top! I'm unable to get past this message to get to the PROGRAM AE mode. I can't find a button or a menu selection that has anything to do with brightness.


Would some kind soul point out the error of my ways so I can get this behind me and successfully select PROGRAM AE?






PS: The firmware version is 2.0

Light & Motion Bluefin Pro for Canon videocameras

22 August 2014 - 12:00 PM

Since the cameras have been sold, here's a revised ad for the housing:


Light & Motion Bluefin Pro with the OLED monitor back for Canon HF-G10, XA10 or HFS30 videocameras. Original cost was $3799.


It comes with the flat port (standard) and the Fathom 90 degree wide angle port, a $1799US option.


There's also a Stix float. Also includes two kinds of attachment bases for lighting (total four) , two for the one-inch ball, the other two for Locline arms. An XIT404 tripod base is also included (no legs).

The setup has been well used; the L&M coating has begun to depart. The housing had an overhaul last October at L&M; both handles were rebuilt at L&M in July 2014, six dives ago. I'd describe it as discolored appearing but 100% usable.


The Pelican case is included.


Since it was about $6000 total originally, I'd like $2250US or near offer.
