Nikon 1 system makes a splash

How many outlets will use that original headline, I wonder, and what inspiration leads to it…

AHN6000_AW1

Today, Nikon released the world’s first interchangeable lens digital camera – if you ignore the military version of the Nikonos RS underwater SLR produced with Kodak. Unlike that specialised system, the AW1 is intended for the consumer and is extremely affordable. Available in black, white or silver metal finish for £749 with standard 11mm-27.5mm F3.5-5.6 Zoom lens (equivalent, in 35mm terms, to 30mm to 74mm) which is rated for 15m submersion, or £949 with the 10mm F2.8 and the zoom, with the 10mm supporting 20m submersion.

Part of NIkon’s 1-series, the AW1 sports the hybrid AF 14Mp sensor, high-speed shooting (now 15fps with continuous AF) and good high ISO abilities that defined the CX-mount family from the start, with some enhancements inherited from newer models and ideal for underwater use. First, though, let’s look at the mount that makes the AW1 so unique.

It’s very similar, in concept, to the Nikonos RS mount, but reversed. Even the familiar grease to maintain the seals is included. Naturally, changing the lenses underwater is not possible, as the sensor and electronics are exposed – and any foreign body such as hair or sand will stand a chance of compromising that seal, so Nikon is placing a great deal of trust in their consumers’ ability to understand and maintain the camera properly.

As a member of the CX/1 family, the AW1’s physical lens mount and registration is unchanged, but the body includes a greater protrusion for the flange with a rubber gasket. On the new underwater lenses, the mount is recessed, with the extension of the barrel including a silicone liner. Mounting the underwater lenses is satisfyingly difficult, making it clear that this is sealing to back up the claims of 15m submersion.

Aiding the underwater experience, the 11mm-27.5mm zoom has a grippy metal zoom collar for most of the barrel, and the AW1 uses an innovative ‘press and tilt’ mode selection – simply hold the mode button, and a virtual pendulum hangs on the LCD to indicate the mode. Tilt the camera body clockwise or vice-versa and it indicates one of the automatic modes for video, creative shooting etc. and selects it without any need for additional buttons or hands. This also eradicates the issue with the early Nikon 1, where the mode wheel could be knocked into a new shooting mode when extracting it from a bag or pocket.

An underwater 10mm prime lens has also been introduced, which can be submerged to 20m.

The AW1 does not make existing CX mount lenses suitable for use underwater, and the underwater lenses will not mount on existing CX bodies such as the V2. Yet the flexibility of the system does allow F-mount lenses via the adaptor, so opting for the AW1 really gives very little away in overall ability.

Other technical improvements include GPS/GLONASS support with compass, depth and altitude meters, shockproof from 2m capability, and an underwater Speedlight (the SB-N10) will also be introduced, though the camera’s own pop up flash can be used underwater. Several accessories have been announced, including the obligatory bright rubber housing which includes a grippy collar for the lens.

We had the opportunity to try a pre-production sample for water, drop resistance and handling, though not photography for publication as the firmware is yet to be finalised, with the camera release date set for 10th October. The silver metal body was particularly attractive, and it seems that at this point, this is where the Nikon 1 system and the CX mount come into their own – offering something truly unique, with a form factor and range of abilities that suits the intended user perfectly.

Pro underwater housing for NEX-5

Posted on By

Most underwater housings for compact cameras are basic items intended for use down to 10m or so. The NEX-5, with its magnesium alloy body and exceptional 16mm f/2.8 optic with fisheye and wide conversion options, is worth far more than that. It can be turned into the modern-day equivalent of the Nikonos rather than a modern day equivalent of that peculiarly unreliable subaqua Vectis which Minolta bowed out with…

Here’s something which we found in an email for B&H Photo Video. It is not exactly cheap – you are looking at a near-$2000 investment to take your NEX and lenses below the waves – but it’s got a specification to make serious subaqua shooters rush for that low-cost NEX-5 outfit to complete the kit. Especially as anything similar for DSLR cameras may cost 50%, 100%, even more than this.

There is a waiting list now – the Montreal manufacturer (reports Photoclubalpha forum member Javelin) is 4-6 weeks from delivery after a big rush following the product announcement. So if you want one of these for summer, get your order in right now, do not delay as all production is likely to be pre-ordered this year.

To complete this you need an extension and dome port front, of course

The Aquatica AN-5 Underwater Housing for Sony NEX 5 Camera is a compact (5.5 x 3.25 x 6″/14.2 x 8 x 15.4 cm) housing machined from a solid block of aluminum designed for the Sony NEX 5 camera. This lightweight (2.2 lbs/1 kg) housing has a baked-on powder coating and is fully anodized against the corrosive effects of sea water. It has replaceable sacrificial anodes, plus pad printed function labels that won’t peel off or fade. It has built-in dual optical connectors, and all controls are easily accessed, with the LCD screen at a more-comfortable 15° viewing angle. A variety of ports are available for the AN-5 housing.

Note: Requires Lens port
Also Note: Most zoom lenses require a close-up diopter filter to correct focus distance.

  • Accurately balanced ergonomic design – all controls are within easy reach.
  • Depth rating: 300′ (90 m).
  • Excellent balance underwater.
  • Replaceable sacrificial anodes protect the housing from electrolysis.
  • Precision machined from a single aluminum block
  • Lightweight and compact housing is fully anodized
  • Covered with baked-on powder coating to protect against the corrosive effects of sea water
  • All function labels are pad printed so they will not peel off or fade.

Pre-order from B&H

This is a new product, and B&H show it as available for pre-order, along with the accessory ports (to fit either the 18-55mm zoom, the 16mm f/2.8 alone or the 16mm fitted with the VCL-ECF1 fisheye converter) and accessory L-type hand grip. See comments above about production and orders. This is a hot product and likely to be hard to get.

The housing is compatible with the Sea & Sea Y110a slave-strobe underwater flash. This will set you back the better part of $1000 more, but it’s been tested synched with the NEX mini flash and apparently all works well. Flash is essential for good colour at depth, even down 5m or so and you’ll require it in many water conditions. The premium option is the twin Y110a dual unit (the housing has two optical connectors for the strobe’s fibre optic triggering cables).

If you are put off by the cost, maybe you can’t afford that two week trip to the Maldives to photograph manta ray convocations – the basic housing is $1399, a typical dome port as shown is $499 (for the 16mm lens alone, only $159 and the cheapest option), the L-grip is $59, there’s also an optional zoom control. But 90m diving with an APS-C live view autofocus camera with f/2.8 lens focusing down to a few inches, usable ISO to 1600 and then more, has to make this worth the cost. And if you want to match the combo, you can easily spend $10,000 on a DSLR with housing which will not get into the same space or handle anything like as well.

Pentax Optio W60 – zoom underwater

Posted on By

PENTAX UK has today announced the release of the Optio W60 compact digital camera.  The W60 boasts improved underwater performance that enables it to operate at depths of 4 metres for up to 2 hours.  It has also been dust and sand proofed to a certified JIS Class 5 Standard and can operate in temperatures as cold as –10°C, making it the ideal choice for both winter and summer holidays, as well as water and extreme sports.

One of the lightest waterproof cameras ever developed, it features a 10 megapixel sensor for exceptionally sharp images. It has also been fitted with a newly developed 28mm wide angle lens, which incorporates an impressive 5x optical zoom.  The lens, designed specifically for the Optio W60, covers a focal range from 5mm to 25mm (approximately 28mm to 140mm in 35mm format) and features a refraction lens system so the lens never protrudes from the body while zooming. This flexibility enables the user to capture a wide variety of scenes, including expansive landscapes, architecture, and crystal clear telephoto shots.

In addition, the Optio W60 boasts enhanced video capabilities and can capture movies at resolutions as high as 1280 x 720 pixels, which is comparable to High Definition TV.  The movie function also incorporates Pentax’s Movie SR (Shake Reduction) technology, which automatically corrects camera shake, and has been optimised for use underwater with the Underwater Movie Mode, which makes use of specific settings for shooting.

The Optio W60’s Face Recognition AF & AE function has also been improved to deliver beautiful portrait shots from a single setting. The W60 can now automatically set the focus and exposure, so that it can detect up to 32 faces at one time – all in as little as 0.03 seconds.   This is complimented by a  SmileCapture mode, which waits until the subject is smiling before releasing the shutter, and Blinking Detection, which alerts the photographer if the subject blinked at the point of capture.

The camera also features advanced Auto Picture which automatically selects the optimal scene mode from seven different options – Flower, Sport, Night Landscape, Portrait, Night Scene, and Standard modes. It also has a highly sensitive Digital SR (Shake Reduction) mode, which compensates for camera shake and subject blurring during still-image photography. This mode automatically adjusts the sensitivity, up to a maximum of ISO 6400, in keeping with the subject’s brightness, to permit a fast enough shutter speed to capture a sharp, clear image. In addition, an electric shake reduction function corrects blurring in images during image playback.

Finally, the 2.5-inch high-resolution (approximately 230,000 dots) LCD monitor is finished with an AR (Anti-Reflection) coating that cuts glare from reflections of external light while being bright enough to be viewed easily even in bright sunlight. The monitor’s wide viewing angle — about 170° both horizontally and vertically — means photographers can conveniently check their shot from nearly any angle.

Other features

  1. Macro mode can be used as close as one centimeter away from a subject for stunning close-up shots
  2. Digital wide function merges two shots into one image for ultra-wide-angle expressions equivalent to a focal length of approx. 21mm in 35mm format
  3. Our proprietary SP (Super Protect) coating adds superior water repellency to the lens’s front protective glass to prevent water droplets from forming
  4. Optional Optio W60 Skin O-CC812 (sold separately) guards the camera from scratches and dirt
  5. Panorama mode stitches a series of up to three shots into one wide photo
  6. Intelligent zoom function extends the zoom range without compromising the optical zoom’s image quality
  7. Supports SD memory cards and SDHC memory cards
  8. Approximately 36.4 MB of built-in memory
  9. Frame composite function allows photographers to shoot and create images with decorative frames; 80 styles to choose from
  10. Date and Time imprint function for easy image categorizing
  11. Includes the ACDSee for PENTAX 3.0 image viewer/image management software, that supports Windows VistaTM
  12. Supports PictBridge, DPOF functions, Exif Print, and PRINT Image Matching
