Published

on

Create impressive images and videos using the groundbreaking Lumix GH5 4K camera, underwater, too, inside the new Sealux CSGH5 housing. This specialist for photos and videos stands out for its characteristics and performance:

  • Professional photo performance with exceptional moiré suppression.
  • 4K 24p cinematic video (4096×2160), plus 4K 3840×2160 60p/30p/24p.
  • High speed 225 area auto focusing in photo or video, perfect for hybrid photography.
  • Durable magnesium alloy body and exceptional shutter life meets the demands of professional use.

If required, the video signal can be transferred to an external monitor via the HDMI socket. These features, together with the integrated Time Code, allow for perfect picture control.

The new Sealux CSGH5 housing for the innovative Lumix GH5 provides perfect support for both photography and video. The basic version of the housing comes without a viewfinder, but the Sealux viewfinders can be added later on at any time to support the new high resolution OLED viewfinder of the GH5. Now, this digital system camera with its superb operability can fully show its strengths underwater, too. The new camera slide makes fitting the camera very easy. The grip fitted at the front is adjustable.

Sealux have designed the precision-fit CSGH5 housing in such a way that you can make perfect underwater use of your Lumix GH5 camera. Safety, easy key operability and all the most important functions allow you to act in a fast, effortless and focussed way, underwater too.  A special socket (optional) enables you to connect an HDMi monitor. This way, high definition image viewing in video mode is perfectly possible using the monitor.  The CSGH5 housing features small dimensions. Large O-rings, double seal shafts and keys sealed even fourfold guarantee a maximum degree of safety. The camera is precision-guided on a special slide and fitted inside the front part of the housing, thereby excluding fitting errors.


Housing

The housing is made of a seawater-proof aluminium alloy. It is CNC milled out of a monoblock, anodized in black and in addition, powder coated on the outside.  The housing has an M6 thread to fit, for example, a small video light (Matrix 2200 Di) or our  5” HDMI monitor on top of the housing for relaxed underwater video shoots.  Minimal dimensions and weight. Excellent taring with all ports.  Ports must be ordered separately. Colour: powder coated in metallic silver.

In addition MF/AF switch, AF/AE-Lock, and the center position of the joystick. Fitted on the left you find zoom or manual focus as well as the lens release facility for changing lenses with the camera fitted inside the housing.

Grip rail

The grip rail is adjustable and detachable for transport. It comes with soft ergonomic rubber handles or grips and two T-pieces to accommodate two flash arms as well as with two threaded holes to attach safety holding straps.

Locking devices 

Two spring-loaded locks with safety catches keep the housing locked with a high clamping force.   Housing bayonet:  The bayonet is sufficiently large to accommodate new large diameter lenses, too. This way, lenses can be changed with the camera inside the housing. The flat and wide angle ports are locked.

Diver Discovering Whale Skeletons Beneath Ice Judged World’s Best Underwater Photograph

Published

on

UPY

An emotive photograph showing a freediver examining the aftermath of whaling sees
Alex Dawson from Sweden named Underwater Photographer of the Year 2024. Dawson’s
photograph ‘Whale Bones’ triumphed over 6500 underwater pictures entered by underwater
photographers from around the world.

“Whale Bones was photographed in the toughest conditions,” explains chair of judging
panel Alex Mustard, “as a breath-hold diver descends below the Greenland ice sheet to bear
witness to the carcasses. The composition invites us to consider our impact on the great
creatures of this planet. Since the rise of humans, wild animals have declined by 85%. Today,
just 4% of mammals are wildlife, the remaining 96% are humans and our livestock. Our way
needs to change to find a balance with nature.”

Whales dominated the winning pictures this year with Spanish photographer Rafael
Fernandez Caballero winning two categories with his revealing photos of these ocean giants:
a close up of a grey whale’s eye and an action shot of a Bryde’s whale engulfing an entire bait
ball, both taken in Magdalena Bay, Baja California, Mexico. Fernandez Caballero took ‘Grey
Whale Connection’ while drifting in a small boat, holding his camera over the side in the water
to photograph the curious whale. ‘The End Of A Baitball’ required Fernandez Caballero to dive
down and be in exactly the right place at the moment the whale lunged. “The photo shows
the high speed attack,” he said, “with the whale engulfing hundreds of kilograms of sardines
in one bite — simply unforgettable to see predation on such a scale.”

Lisa Stengel from the United States was named Up & Coming Underwater Photographer of the Year 2024 for her image of a mahi-mahi catching a sardine, in Mexico. Stengel used both a very fast shutter speed and her hearing to catch the moment. “If you listen there’s an enormous amount of sound in the ocean,” she explained. “The action was too fast to see, so I honed in on the sound of the attacks with my camera to capture this special moment.”

“It is such an exciting time in underwater photography because photographers are capturing such amazing new images, by visiting new locations and using the latest cameras,”
commented judge Alex Mustard. “Until this year I’d hardly ever see a photo of a mahi mahi,
now Lisa has photographed one hunting, action that plays out in the blink of an eye.”
The Underwater Photographer of the Year contest is based in the UK, and Jenny Stock,
was named as British Underwater Photographer of the Year 2024 for her image “Star
Attraction”, which finds beauty in species of British wildlife that are often overlooked.
Exploring the west coast of Scotland, Stock explained “in the dark green depths my torch
picked out the vivid colours of a living carpet of thousands of brittle stars, each with a
different pattern. I was happily snapping away, when I spotted this purple sea urchin and I
got really excited.”

In the same contest, Portuguese photographer, Nuno Sá, was named ‘Save Our Seas
Foundation’ Marine Conservation Photographer of the Year 2024, with his photo ‘Saving
Goliath’, taken in Portugal. Sá’s photo shows beachgoers trying to save a stranded sperm
whale. The picture gives us hope that people do care and want to help the oceans, but also
warns us that bigger changes are needed. “The whale had been struck by a ship and its fate
was sealed,” explains Sá. “An estimated 20,000 whales are killed every year, and many more
injured, after being struck by ships-and few people even realise that it happens.”
