#362123 How do I avoid my wife murdering me when I come home with two more YS-250Pro...

Posted by JackConnick on 11 June 2015 - 08:20 PM

I ended up with an uw camera company. Now it's all work related and a write off. At least that's what I tell her.

#361640 Olympus 7-14 mm f2.8 will not fit in Nauticam housings

Posted by JackConnick on 30 May 2015 - 08:52 AM

We tried it in the Nauticam E-M1 housing and it will require that you add the camera body first into the housing, then the lens as with the 12-40mm. But it will need a much wider port body to fit the lens and a zoom gear. My guess is the the Nauticam N85 (MIL) to N120 (DSLR) 40mm ext adapter with zoom control, plus about a 50-60mm N120 extension and Nauticam 180mm N120 (DSLR) dome (or larger) should work fine. But Nauticam has not released a guide yet as they are still testing these new lenses.

 

We have a "first look" article on our blog here.

#359501 After trip housing maintenance

Posted by JackConnick on 01 April 2015 - 11:08 AM

You might want to check out our Maintenance Handbook. Warm water and vinegar will dissolve salt, maybe a spray of silicone lube and light grease. You can take out the main o-ring and put it in a baggie inside the housing.

#353385 Free Olympus E-M1 V.2 Firmware Update - Try New Creative Underwater Technique...

Posted by JackConnick on 15 October 2014 - 07:32 AM

om-d-e-m1.png
While at first glance Olympus's new free OM-D E-M1 camera firmware upgrade v2 doesn't appear to offer much for underwater photography, digging into some of it's subtleties and improvements shows that it offers some pretty interesting ideas to expand your underwater universe.

The features added include most all of the latest ones now found on the new PEN E-PL7. It's not often that you can apply these types of upgrades to a camera that's nearly a year old.

Besides some improvements such as speeding up it's EVF display, more and smaller AF points, and improved focus peaking, there are a lot of new in-camera creative possibilities available such as using Keystone Correction to straighten the lines of a wreck, or maybe stalks of kelp, while shooting with a fisheye lens - right on the camera back. Same with it's Live Composite Tool; allowing for multiple exposures to be made creatively without post-processing. Other cool effects like Partial Color are now available, allowing you to shoot a brightly colored subject against a black and white background.

Do you like HDR? This popular technique of shooting and overlaying multiple varying exposures can be set-up and shot right on the camera. Using a high-frame rate, these HDR composites can be previewed on the camera display and then saved into RAW for further manipulation later. New is ev compensation on the HDR frames.

Updates have also been made to the wireless apps and tethering software, along with many other features you'll enjoy using above water. You can also use them to apply filters and create composite "stories" and upload them with your phone; without even opening your housing!

If you have one of these great Olympus micro-four thirds cameras, getting this free E-M1 firmware update is a no-brainer. It is easily downloaded onto a computer, then uploaded to the camera with the mini-usb cable included with the camera.

So enjoy this cool new present from Olympus and think creatively underwater, you might be surprised!

More information on the OM-D EM1 can be found here. You can download the updater here.

Here's a complete list of new features and changes:

8 New Functions:
  • Keystone Compensation (Digital Shift)
  • Tethered Shooting System (OLYMPUS capture)
  • Live Composite
  • Zoom In/Out and Layout have been added to Photo Story. Save (complete partway through), Temporary Save, and Resume functions have been added to Photo Story mode
  • New Art Filters: Vintage and Partial color
  • Old Film Effect in video recording
  • The Aperture Lock function has been added to Aperture Preview
  • The Panning Shot shooting mode has been added to SCN mode
16 Operability Improvements:
  • Image display time lag in the Electronic Viewfiner has been improved to 16 msec (frame rate setting is high speed)
  • Multiple simultaneous settings now available in Live Guide
  • Exposure compensation (±3 EV) is now available in HDR 1/HDR2 shooting
  • A function has been added to cancel Color Creator and return to the original Picture Mode by pressing the MENU button when using Color Creator function.
  • Movie Tele-converter can now be used simultaneously when Art Filter is set to Picture Mode.
  • AF function for each frame was added to Custom Self Timer. In Drive Mode's Custom Self Timer settings, you can now press the INFO button to change settings.
  • MF Assist is now supported in magnified frame position.
  • 3x has been added to high resolution magnified Live View.
  • The Peaking display frame rate has been improved.
  • Electronic zoom speed setting function was added. An icon appears on the LCD monitor when using an Olympus electronic zoom lens.

  • Double tap is now supported in touch operations on the Super Control Panel.
  • The level gauge and histogram can now be displayed during magnified frame display. The Touch Off icon was added to magnified frame display.
  • A function was added so that shooting information recorded in HDR1/HDR2 can be viewed in the playback screen.

  • When the BKT button is held down, the BKT menu now appears.

 




#352861 D800 + Sigma 15 + 1.4x Converter. Anyone tried?

Posted by JackConnick on 23 September 2014 - 05:53 PM

Hi Matias;

 

I shot quite a bit with this in Fiji. I think it works out pretty well. Others felt that you should just get closer, but sometimes it doesn't work out that way. I used the Kenko 1.4 TC, not sure about the new Nikon.

#352590 Problems triggering Ikelite strobes with housing Sea&Sea Nikon D200

Posted by JackConnick on 15 September 2014 - 04:37 PM

You may have an issue with the Nikon's TTL sync pin freezing the camera when it gets the wrong connection. Does the camera still operate or does it lock up?

 

You can put a small piece of electrical tape over the one pin to see.

Also with dual bulkheads it can get tricky. You have to turn on the stobe that's the master and then the strobe that's the slave...although I'm not sure if that applies to Sea & Sea housings.

 

Refer to Ike's FAQ for help: http://www.ikelite.c.../faq/cords.html there's a couple of Q/A's on this issue.

#352527 Am I going soft: Nikkor 16-35mm

Posted by JackConnick on 14 September 2014 - 08:30 PM

I dunno, you shouldn't have to be using diopters at all if you have a large enough port. All you are doing is taking a great optics and dumbing them down, IMHO.

 

I think the main issue is that the port is too small. Stopping down and adding a +2 helps a lot, but until you shoot that lens with a 9" port, I would expect corner issues. Shooting vertically, you can put two corners in the blue so it's not as apparent. But the Sigma 15FE or Nikon 16FE will shoot rings around the 16-35 for sharpness, especially with a smaller port.

 

Rectilinear zooms are best used for big animals where you need a little more reach, than CF/WA.

#352366 Sony a7 / Sea of Cortez - Pics

Posted by JackConnick on 06 September 2014 - 12:24 PM

A few pics and video from our recent Sea of Cortez trip on the Solmar V. Originally we were going to go to the Socorros, so I didn't have a macro lens along.

 

The Sony a7 is ground-breaking is a full-frame mirrorless camera, lots smaller and lighter than my D800 for sure. Better low-light and a host of programability. BUT lens offerings are pretty scarce. Hopefully by the end of the year this should be improved.

 

With some of the viz "challenging", I ended up shooting a fair amount of shallower available light. With the a7's low-light abilities it was easy to shoot up into the 2-3,000 ISOs without much degradation at all.

 

Using the manual focus Nikonos lens was a bit different, but it has such a long depth of field that I just stopped it down and only changed focus from CF/WA to WA as necessary. Using focus peaking it was easy to shoot when you saw the "reds" of their eyes! I also used the 28-70 and for a "kit" lens it isn't bad, with a close up diopter, I think it would work out well. I did shoot some moderate close ups and with the huge files, a little cropping came up with some pleasing images.

#352094 Red Focus Light

Posted by JackConnick on 28 August 2014 - 02:29 PM

Red will usually disappear around 1/80-1/100th.

 

Connect both to the housing, otherwaise you'll be swimming with a kelp trap with a wire between the strobes.

#350805 Socorro lens options

Posted by JackConnick on 25 July 2014 - 07:07 AM

Tim,

 

Proscriptive? Heck, in my old age, I've been going back to primes. Fast, cheap and sharp. Zoom with your fins!

 

Not to get off the OP's questions, but I'm dying to try the Nikon 28 f/1.8 on a D800 there...

 

Echo Tim's comments about murkiness at times in Socorros... viz can be up and down, as wind blows volcanic ash off the islands into the water, or surge stirs up the bottom. Of course, that's when you see the largest schools of hammerheads...

 

Whatever lens you take, you'll have a great time!

 

Jack

#350714 Socorro lens options

Posted by JackConnick on 23 July 2014 - 10:09 AM

You can use the 10-17 + the TC and get a little more reach. I've found this to be a sharper solution than the Sigma 17-70 which is about the only other lens I like underwater. The 17-70 is fairly useful and has a good range including sort of a close-up mode. But I don't think it's got stellar sharpness.

 

I've shot all three of these solutions down there. Mid-range zooms tend to be slower lenses and don't shoot very well uw (poor corners, etc.). Socorros can be murky at times.

 

I think a larger dome does give other options, and you can shoot at more wide open apertures than in the mini-dome, so I would recommend looking into that. The 17-70 requires a large dome and a 50mm extension, so it tends to be a bit bulky for shooting in blue water. Shooting a 60 behind a dome is a decent sort of shark setup for more reach, fairly sharp and fast, no extension.

 

Here's a couple of examples shot there.

 

Sigma 17-70 D300:

This was at 29mm, and could of been shot wider, but the Manta was moving quickly.

#344718 Sigma 15mm fisheye focus problem

Posted by JackConnick on 19 March 2014 - 08:36 PM

I think you need the extension if you're not getting focus. Even with it you'll have corner issues with that small a port. But for video it should be ok, especially if you stop down.
