#373483 Switching to optical sync. D810 continuous release with pop-up flash???

Posted by Ryan on 10 May 2016 - 01:54 PM

The OP is asking about what I consider to be a Nikon weakness, and that regardless of flash recycle time, you have to pull the trigger once for one frame when the flash is popped up.  In other words there is no such thing as continuous shooting mode when the internal flash is popped up.

 

This is one reason that manual led triggers have been created for some housings...  Pavel's TTL Converter is actually a very good manual trigger as well, I share his enthusiasm.




#373480 Nauticam WWL-1 Lens / Buoyancy Collar Review

Posted by Ryan on 10 May 2016 - 01:04 PM

There are some solutions coming in the next few weeks to improve access to the lens release button, and provide cover solutions, when the foam ring is attached.  I'll update this thread when I have them in hand.




#372610 Review of the new Nauticam wet wide angle lens WWL-1

Posted by Ryan on 14 April 2016 - 12:47 PM

I just noticed the request above for comparisons, and have these v. Panasonic 7-14 and Olympus 9-18.

WWL-1 is significantly wider than both of these, with some barrel distortion.  Keep in mind the lens is full zoom through, and when you frame to match the fov offered by these two options a lot of the barrel distortion is cropped out in camera.




#368997 New Nauticam 29 port for Panasonic 14-42mm PZ could be a blast for 4K video s...

Posted by Ryan on 06 January 2016 - 06:01 AM

This combo does vignette at 12mm, but it is gone by the time you zoom out to 16mm.

 

Will the WWL work with the olympus 12 50 lens 'n the Nauticam N85 Macro Port /
will it vignate at the 12 end



#368995 Sony A 7 Sii with Nikonos 15mm for 4K

Posted by Ryan on 06 January 2016 - 05:42 AM

Our service staff made these.  TSA loves them.  I haven't heard real world reports, but bench tests indicate at least 3 hrs run time while recording video.

#365989 Relative low light and video capabilities of Nikon Cameras

Posted by Ryan on 07 October 2015 - 04:32 PM

Hi Tom,

 

If you want the best low light, high iso camera ever made by anybody I'd buy some variant of Sony A7S.

 

If you care about in camera UHD recording and in body image stabilization, buy this one:

http://www.sony.com/...meras/ilce-7sm2

 

and if you don't, buy this one:

http://www.sony.com/...cameras/ilce-7s

 

and one of these if you want to use your Nikon lenses (you'll set aperture on the adaptor)

#365898 Tokina 10-17 overexposed at 10mm

Posted by Ryan on 05 October 2015 - 10:41 AM

I'd suggest getting the lens serviced.  My guess is that there is something mechanically wrong with the lens, or there is oil on the aperture blades, that is preventing them from closing during exposure.

 

You can test this further with DOF preview.

#364906 New Panasonic GX8

Posted by Ryan on 02 September 2015 - 10:57 AM

G7 has indeed been cancelled.  The issue, as speculated here, is the front - back depth of the hand grip.  The thick grip would have moved the N85 Port mount forward, affecting compatibility with all of the micro four thirds lenses supported, and necessitating a port system dedicated to the G7 housing.  

 

GX8 is no problem, and that high priority design is moving forward.




#363115 Olympus 7-14 mm f2.8 will not fit in Nauticam housings

Posted by Ryan on 11 July 2015 - 07:12 AM

They went for the previously speculated 30 mm extension on a dome port for the Pana 8 mm fisheye.

 

Undoubtly the Nauticam 4,33 mini dome with the 30 mm mini extension should also work.

 

This does "work", but there is vignetting from the lens shades at the top and bottom of the 4:3 frame, so it won't be the recommended option.  

 

The official recommendation for Olympus 8mm f/1.8 Pro will likely be 36048 140mm Glass Dome + a new 17mm extension, but these options are undergoing ongoing testing.

 




#363102 Mezzo Canale Shoal [Tuscany - Italy]

Posted by Ryan on 10 July 2015 - 03:00 PM

The diving looks amazing, and the housing feedback here is interesting.  

 

What is the water temp?

 

A7 definitely isn't the top choice for video shooting, but it is serviceable.  A7S is outstanding.

Sony has a 16-35 f/4 lens in the FE (full frame E-) mount that has been available for a few months, and works well in the 180mm glass dome.  This is actually one of the best wide rectilinear zooms I've used, and I am really impressed by the performance in the relatively small dome.  FF systems from Canon or Nikon typically require something much bigger...

 

I really like Sony's strategy with the "purpose" built models that use the same lenses, and go in the same housing.  A7, A7R, and A7S all use one housing, A7 II and (fingers crossed) A7R II should use another.  This allows me to have high resolution (A7R) and highly sensitive (A7S) bodies that I can use interchangeably, as needed, in one housing.  These have been my primary two travel cameras, using A7S for video and at night, and it has made flash obsolete.




#361320 Nauticam flextray not so good, alternatives?

Posted by Ryan on 19 May 2015 - 11:47 AM

HI Oskar,

I've sent you a PM, but it would be good to get a bit more info on the age of this system.  There was a known issue that caused something like this with some early handles.  It was corrected, dealer stock was replaced in those cases.  If this is that problem, it looks like yours was missed.

 

It is normal for the handles to have a bit of flex in them, which some people don't enjoy, and is amplified with heavy strobes or video lights.  The handle bracket has been added as an optional install to knock that out.

 

Moses, I wouldn't worry about the strengths of those the handle bolt attachment.  They brackets are optional, and something like 20 models used this tray prior to their being added.

 

Handle brackets were never offered for E-M5.  The mounting holes you see on the right grip are for an accessory hand strap, not a bracket.  I'm confident that once you get a current handle this won't happen again.




#361076 Nauticam deep housing

These are now being handled as special order items, and are possible for most models with a reasonable up charge ;)


#357460 Panasonic LX-100 Nauticam housing

Posted by Ryan on 05 February 2015 - 06:18 AM

Thomas Lam from Nauticam deserves a lot of credit for taking the time to actually measure these (and basically every other lens on the market).  The measurements were actually done twice by Thomas, and verified by Alan Dewey at Reef Photo.

 

The CMC magnification table listed in the press release is actual measured data, in water.

 

Working distance is measured from the front of the housing port, or front of accessory lens.  It is the actual space between the underwater system and subject.

 

All of the systems listed achieved their best "native" magnification at their widest focal length, and very close to the subject.  

 

All of the systems listed achieved the magnifications listed with CMC are at full telephoto.  It is possible, but not likely that some of these could actually have slightly better magnification if you pulled the zoom back a couple of clicks.  In the interest of consistency we didn't try to establish these situations.  We wanted repeatable results.

 

CMC isn't just a simple diopter, so I'm going to try to resist those comparisons.  The actual end magnification with today's top compacts (RX100m3, G7X, and LX100) was in line with simple housed +15 diopter macro lenses.  There were noticeable image quality differences, though.




#354701 Move over Sony RX100 (I, II, III), Here come Panasonic LX-100

Hey Moses, come on down this weekend and you can take the LX100 for a dive...
