#341518 On-Camera Flash Setting for Fiber Optic Trigger

Posted by Stewart L. Sy on 07 January 2014 - 10:50 AM

2-3 Second recycle time is based on a full power dump from the D1.  If you lower your flash power to around half power, the D1 can keep up with your 7D firing at 3 fps.  I shoot my D1's at just under half power and it keeps up with my 5dmk3 at 6 fps.


Of course, good NiMH cells (Maha Powerex) help too.


There's no point in shooting full power on your pop-up flash when shooting in manual, you just need to trigger the D1, then control strobe power on strobe.

I did the upgrade, IQ wise, not a huge diff, but usability of the body, the fantastic AF...I have no regrets.  It's a true shooter's dream.




p.s.  I waited a year before I upgraded...

#338137 Sonys' new A7(r) FX mirrorless

Posted by Stewart L. Sy on 14 October 2013 - 03:05 PM

As adapters already exist for the current E-mount line to enable the use of Canon (and Nikon) lenses, the A7 won't be a "game changer" at all.  Especially if one starts using lenses that can throw an image circle large enough for a 24x36 sensor.  The m43 format is great as the sensor is 1/4 the size of a FF chip, so lenses are that much smaller. But start wanting a 100mm macro or 15mm FE (our standard UW lenses), then you're no better off that using a DSLR with crippled (as per current technology) slower AF.  When you start considering topside lenses like a 70-200 or more...then the camera becomes a liability than anything as it's too small a "handle" to properly stabilize the bigger lenses against one's body/face.  Remember too, theoretically, FF lenses require larger elements, leading to more expensive glass.


I love my NEX-6 and my ability to use my Canon EF lenses with the Tech-Art adapter AF is still hit/miss with the on sensor phase detect.  Navigating through menus can be a bit of a pain in the rear end and while soft keys are easily customized, it's not in the same league as a DSLR.  Yes, it's easier on the shoulder to carry around, but when it's the "must get it shot" moment, I still reach for my 5dmk3 or 7D.



#337085 Wide Angle Lens Recommendation for a Full Frame Canon 6D?

Posted by Stewart L. Sy on 16 September 2013 - 11:32 AM

Hi Johan,


The macro was a mix of the Sigma 150 non-OS and the Canon 100 f2.8 non-L macro.  I also used the Aquatica +5 & +10 close up diopters.



#336893 Wide Angle Lens Recommendation for a Full Frame Canon 6D?

Posted by Stewart L. Sy on 10 September 2013 - 08:26 AM

Hi Christine,


I shoot the 5dmk3 and I use the Tokina 10-17 with a 1.4 TC.  All the wide angle shots here: http://stewartsy.com/anilao-2013/  were taken with that combo.  I used the combo behind the Aquatica mini-dome (4").  The lens was usable from about 12mm-17mm.  I've printed some of them to 16x24 and the quality is outstanding.





#333210 Sea & Sea YS-D1 Strobe's Diffuser Lanyard connection?

Posted by Stewart L. Sy on 21 June 2013 - 10:24 AM

The D1 has a small loop molded into the body specifically for securing the lanyard that the diffuser comes with....

Rick, I was around 6 - 8 inches away from the anemone fish.  Cary, 4" Mini-dome.


#332122 WA with the 5dmk3, Tokina 10-17, 1.4TC and Aquatica Minidome

Took this last week in Anilao, Bonito Island to be exact.



Camera & Exposure Specs:  Canon EOS 5dmk3, Aquatica A5dmk3 Pro Housing, Tokina 10-17mm with Tamron SP1.4 Pro TC, Twin S&S YS-D1 Strobes on full. ISO 200, f16, 1/100.  Lens zoomed to 12mm plus TC= 16.8mm, Aquaview 45 was crucial to the comfort of the shooter while taking this shot. :bananashark: Plus it helped with getting the housing down closer to the reef.





#328357 Canon 5d mark iii AF

Posted by Stewart L. Sy on 22 March 2013 - 09:19 AM

That would be the wrong thing to do.  Set up the camera to single AF point then use the joystick to move the point around to where you want the focus to be.  Activating all 61 points gives up that control and the camera could lock on to something that you don't want.
