Olympus TG-4 is first rugged compact to shoot uncompressed RAW photos

Olympus has introduced a new high-end rugged camera in its Stylus Tough series, the TG-4. It isn’t radically different than its predecessor, the TG-3, but Olympus says it’s the first rugged compact camera to offer uncompressed RAW capture and a new underwater high-dynamic range (HDR) mode.

Like the TG-3, the TG-4 uses a 16-megapixel, 1/2.3-inch backside-illuminated CMOS sensor, TruePic VII image processor, and a fast f/2.0, 4x optical zoom lens (25mm wide-angle) that has a microscope macro mode that can magnify up to 44.5x. There’s Wi-Fi and GPS built in. The TG-4 retains its predecessor’s rugged attributes: waterproof down to 50 feet, crushproof to 220 pounds, freezeproof down to 14 degrees Fahrenheit, shockproof from 7 feet, and dustproof. Olympus says the crushproof rating is what makes its rugged cameras unique. Video recording is still Full HD 1080.

Shooting images in RAW means larger file sizes, but you have the benefit of greater adjustments to exposure, contrast, white balance, and color balance during post-editing, thanks to the extra information captured. Many casual users will be fine with JPEG for viewing and sharing, but advanced users will appreciate the option, especially when shooting in environments with challenging light. And with AF Target, you can tell the camera where you want it to focus.

Olympus Tough TG-4 highlights:

  • Uncompressed RAW image capture
  • Enhanced GPS accuracy, Wi-Fi
  • Underwater HDR, Nighttime Live Composite modes
  • Autofocus Target selection
  • Microscope Mode
  • 16-megapixel BSI CMOS sensor
  • 4x optical zoom lens with f/2.0 aperture at wide-angle

For the TG-4, Olympus added two custom modes on the mode dial, which you can use to save often-used settings. There’s a new Live Composite mode for shooting night scenes and star trails; from multiple shots, the camera takes the brightest areas and combine them to create the image. Another new mode is Underwater HDR that corrects color tones and exposure shifts – an issue when shooting in the water where lighting is an issue. GPS performance has also improved, thanks to use of additional satellites for more accuracy.

There are also new accessories to complement the TG-4. These include a Sport Holder for securing the camera to a backpack or belt and using it like an action camera, and an underwater case that increases the depth level.

Available in May 2015, the TG-4 will list for $380. It comes in black and red.

Since the TG-4 has similar specs to the TG-3, we can make some predictions. We appreciated the TG-3’s rugged qualities, great-looking underwater images, and the Super Macro microscope mode., and we expect the same from the TG-4. However, we found the TG-3’s low-res LCD and high ISO performance to be bummers; the TG-4 has the same specs, so we aren’t likely to see improvements on this front. The recently announced TG-860 has a flip-up LCD, but the TG-4 retains a fixed position. Still, we think the TG-4 is nice improvement, and the ability to capture in RAW is a good feature.

DJI Mini Pro 4 leak appears to reveal the drone’s specs
A retail box apparently showing DJI's upcoming Mini Pro 4 drone.

DJI appears close to unveiling the Mini 4 Pro, the successor to the Mini 3 Pro that launched in May last year.

First, as a reminder, DJI’s smallest and lightest “Pro” drone tips the scales at just 249 grams, a carefully considered move as it’s just 1 gram below the drone weight category that involves having to register it with the authorities. Sure, that’s no great hardship for most folks, but the fewer hoops you have to jump through to get your bird in the sky, the better.

GoPro: Introducing HERO12 Black | Everything You Need to Know

GoPro is back with the latest iteration of its popular action camera. The new GoPro Hero 12 Black is the kind of solid piece of kit we’ve come to expect from a company that’s been in the game for years. That’s actually created a bit of a problem for GoPro, with many customers happy to hang onto their current model rather than upgrade. So it'll be hoping the latest version will be attractive enough to prompt a wave of purchases among current owners, while at the same time attracting a bunch of first-time buyers, too.

How to hide photos on your Android phone or tablet
Google Photos

While modern smartphones are quite secure as long as they remain locked with a passcode or biometrics like a fingerprint, by default those features only protect the front door. If someone picks up your phone while it's unlocked, there aren't typically any barriers that will keep them out of exploring everything from your contacts and emails to your photos.

This can be particularly challenging when it comes to photos, since those are the things we like to show off the most from our phones. We've likely all had those moments when we want to show a friend or co-worker a funny cat meme, so we hand over our phone and trust that they won't swipe right and see the photo of the hairy mole that we sent to our doctor that morning.
