Lumix G9

Which Camera For Which Dive

Posted on by in underwatermacro and tagged , , , , , , , , , .

I have 3 camera setups that I’m using now, and I use them (or not) at different times.  Like most things in life, it’s all a tradeoff between simplifying the dive, flexibility in photography, and image quality.

Action Cam: “Small and Wide”

I have a Paralenz and my wife has a later-model GoPro.  They just clip onto your BCD and you don’t need to worry about it unless you find something to shoot.  They’re good for wide-angle point-and-click shots and the GoPro with a Backscatter Flip magnifier means that you can take pretty decent macro video and OK macro stills if you add some torch light.

When to take:

  • Non-intense dive classes with minimal practice skills.  Like Advanced Open Water or a deep diver specialty.
  • Group dives.  You don’t have much time to take photos anyway.  And the pictures you usually take are of other divers.
  • New gear where you feel OK with buoyancy and trim but still want more practice dives.
  • As a wide-angle backup to a dedicated macro rig.

Protip: most divers have pictures of everybody else.  Try diving with other photographers and make a “photo sharing pact”.

Olympus TG5: “The Recon”

I had been borrowing my wife’s TG4 with Olympus housing (OK, it was originally mine but then I traded her for her EM-10II because it has a fully manual mode).  Now I have a TG5 with a Nauticam housing and light ring.  Both of the TGs are pretty cool cameras and if you have the experience and skills you can take some really good pictures.  In fact, a good photographer with a compact camera can blow away lesser photographers with a $25000 camera setup.

When to take:

  • Learning a new area or looking for new critters.  The name of the game is covering more distance underwater to learn the layout.  You’ll swim more than take photos, and you’ll swim faster if you’re not pushing a large camera through the water.
  • Lobstering, trash removal, or other activities where photography is secondary but you know that there are good photography subjects in the area.
  • Dives with heavy current or surge.
  • Areas where you’ll be taking both wide-angle and macro on the same dive.
  • Trips where you have a long flight and don’t want to carry a heavy suitcase full of camera gear.
  • Solo dives where you want to minimize weight getting in to and out of the water.  For example, in cold water I have a drysuit, 30+kg of weight, 14L HP cylinder, and a 5.5L stage cylinder.  That’s heavy for a shore entry.

Protip: take a SMB, tie it down where you find a good subject, and come back on the next dive with the big camera.

Panasonic Lumix G9: “All the Things”

The G9 is a mirrorless Micro 4/3 camera that does awesome macro.  With a Nauticam housing, it can take all sorts of accessories.

When to take:

  • Dives where the main purpose is macro photography.
  • Tiny subjects perfect for supermacro where you need the magnification that 15x worth of wet diopters will give you.
  • Times when you need bigger resolution for cropping or printing.
  • Dark and deep conditions where you need all the flexibility in lighting that you can get: dual strobes, focus light, video light, etc.
  • Dives where you have a spotter and you can get as much “trigger time” in as possible.
  • Easier diving conditions.  Low current and surge.  Shorter swims.  Shore or boat crew to assist with entry and exit.

Don’t Take a Camera: “Enjoy the Dive”

There are even some times when I don’t take a camera.  *gasp* *cue shock and awe*

When to not take:

  • Serious dive classes.  You can’t do drills and carry another diver out of the water if your hands are full of camera.
  • Your first 30 dives.  Learn buoyancy first, OK?  That way you’re not killing coral or animals on the bottom.
  • Major adjustments in gear or environment.  For example, going from tropics to drysuit in cold water.  Times where your buoyancy and trim are going to be messed up and you need to focus on that for a handful of dives and the less extra gear you have the better.  It reduces your task-loading and stress.  Later on, I’ll switch to the TG5 if I’m more comfortable and once I know that I can dive in that setup without problem, I’ll start carrying the G9.

Review: Underwater Macro on the Lumix G9

Posted on by in underwatermacro and tagged , , , , , , , .

In March, I bought a new Panasonic Lumix G9 to replace my EM10 MkII.

So far, I like it, both on land and in the water.  It’s worked out pretty well for me.  I’m at the end of a month-long trip consisting of the following:

  • 8 days in Raja Ampat and Misool
  • 10 days in Bali: Padang Bai, Tulamben, and Ubud
  • 5 days in Santorini (no diving, lots of donkeys and white buildings)
  • 5 days at home in Massachusetts (no photography)
  • 5 days in Athens (no diving, lots of buildings made of rock)

I think I’ve carried the G9 every single day on this trip except for when I went home.

Some notes in no particular order….

Housing.  Since the camera was just released in February, it’s still early for the housing to be in the usual dive photography shops.  I went to the Nauticam booth at the Asia Dive Expo in Singapore and bought their demo model.  Nauticam is starting to make their mirrorless housings more like their DSLR housings.  This is a shift in price and features: $1400 for an EM10II housing v/s $2600 for the G9 model.  There is a fully-removable back on the G9 v/s the hinged back on my EM10II. And the G9 housing has 2xM14 and 1xM16 bulkheads (one M14 has the vacuum system valve) v/s the single M14 bulkhead (where I put a vacuum valve after purchase) that was on the EM10II.

Accessories and Lenses.  I went from one Micro Four Thirds camera to another Micro Four Thirds.  That means that my lenses, housing ports, strobes, arms, etc still stayed the same.

I’m still using the Olympus 60mm Macro, Nauticam port, and Supermacro Converter (SMC-1) for macro and supermacro.

I’m still using my Olympus 7-14 Pro with 180mm glass dome for wide angle.

Flash Trigger.  I did lose an onboard flash (the EM10 has a built-in flash that I used to signal the strobes), so I needed to get a flash trigger.  I got one bundled with the housing.  Sadly, it doesn’t do optical TTL, so I’m running my strobes in manual mode.

Image Stabilization.  The G9 has some serious image stabilization.  What that means to photographers is that you can run a slower shutter speed without blurring the photo because of your own motion.  This is cool on land, but only 25% as awesome in the water because our subjects are moving.  That is, if you’re taking pictures of a nudibranch in a current, image stabilization helps where you’re moving but not where the subject is moving.  Still, it’s a good thing to have.

Back Button Focus.  This was fairly easy to set up: assign the F1 button as the AF Lock button and turn off half-press AF on the shutter button.

Joystick.  The housing doesn’t have controls for the joystick.  It’s OK, I don’t miss it underwater.

EVF and LCD.  For macro, I use a Nauticam 45-degree viewfinder.  The Electronic View Finder (EVF) of the G9 is awesome and works great with the Nauticam viewfinder.  Although folks with glasses might want to try setting the EVF resolution (v.mode button on the right side of the EVF) to a smaller size if they need to.  The housing doesn’t have a button to set the EVF.

I use the LCD for underwater wide-angle photography.  The LCD seems to be a little bit darker than the actual picture.  After awhile you’ll get used to it.

For switching between EVF and LCD, the F3 button to the left and below the EVF works great.  There are 3 modes: LCD, EVF, and switch back and forth using the sensor built into the EVF.  In the last mode, the housing will always set off the sensor, so it’s functionally the same as EVF.

Filming Video.  4K60P video is awesome, and the housing has a button for it.  Just film away.  However, I have yet to figure out how to do playback of videos on the camera underwater because the “play” button is on the LCD as a touch control.

Red-Light Focus.  The camera has some problems with focusing while I was using a red focus torch and point-focus.  The phase-detection software in the autofocus engine gets confused by so much of a single color.  So I switched to back-button focus, moved the camera off of the subject, locked focus on the bottom using white light, and switched back to red light for the real subject.

High-Resolution Mode and Focus Stacking.  It’s like HDR but for high resolution images of 80MP (by the way, high-resolution files are huge) or for extended depth of field.  On land, you need a non-moving subject and a tripod.  It doesn’t work in underwater photography unless the camera and the subject don’t move.  However, on land it’s awesome for the sunrises and sunsets and landscapes that crowd around dive sites.

Burst Shooting.  I forgot to try this underwater but I’ve used it quite a bit with my wife and niece while they were swinging on giant swings or jumping on beaches… the usual fast-action tourist shots.  It would work underwater provided that you turn off your strobes and take the photos with either natural light or focus/video lights.

Burst shots do make a lot of files very quickly.  Each file is 18-20MB in size for RAW files.  I go through and delete the rejected shots in Lightroom Library Module to save hard drive space.

Reading Raw Files.  MacOS and Windows can’t read them natively yet, so you have to manage photos in LightRoom.  This will eventually change with updates from the operating system vendors.  I did keep on “Save as RAW and as low-quality JPG” for awhile so that I could manage files with the OS, especially where I forget to format the SD card.  However, it slows down the SD card writes so I eventually moved it to write just RAW files and my camera operator (ie, myself) was trained enough to remember to dump files off card and format card at the end of each day.

S-Curves.  For macro, I use +5 to highlights and -5 to shadows to add a lot of contrast to the photo.  Because strobes sometimes kill the contrast: they work too well.  Back on land, it’s a bit too extreme and the family complained about how this looks in their tourist shots.  So I have to go back to a normal curve for land photography.

Settings for Underwater Macro.  I have a couple of things that I set for macro:

  • Photography Menu
    • Quality: RAW.
    • Photo Style: Vivid.
    • Metering Mode: Spot.
    • Highlight-Shadow: +5 Highlights, -5 Shadows.  Because strobes kill contrast sometimes.
  • WrenchC
    • Focus/Release Shutter
      • Shutter AF: Off.  Turns off focus at half-press.
      • AF Assist Lamp: Off.  Doesn’t work inside a housing.
    • Operation
      • Fn Button set
        • REC Mode
          • Fn1: AFL AEL.
  • Mode Dial: Manual

Settings for Underwater Wide-Angle.  Yes, I do wide-angle sometimes.  I set the following:

  • Photography Menu
    • Quality: RAW.
    • Photo Style: Natural.  Because vivid amplifies the blue-green look underwater.
    • Metering Mode: Spot.
    • Highlight-Shadow: +3 Highlights, -3 Shadows.  Because water kills color and contrast.
  • WrenchC
    • Focus/Release Shutter
      • Shutter AF: On.  Turns on focus at half-press.
      • AF Assist Lamp: Off.  Doesn’t work inside a housing.
  • Mode Dial: Shutter Priority

Settings for Dry Photos:  Even more amazing, I even take photos on land.  Here is what I set:

  • Photography Menu
    • Quality: RAW.
    • Photo Style: Vivid.  Because I like it.
    • Metering Mode: Area plus spot.
    • Highlight-Shadow: +0 Highlights, +2 Shadows.  Because outside photos with the subject in the shadows.
  • WrenchC
    • Focus/Release Shutter
      • Shutter AF: On.  Turns on focus at half-press.
  • Mode Dial: Shutter Priority

See you underwater!!!
