Best Pocket Camera of All Time: Sony Cyber-shot DSC-RX100

Until now, anyone looking for the best pocket camera available would be hard-pressed to find anything better than the Canon PowerShot S100. The Sony Cyber-shot DSC-RX100, announced today, looks set to surpass the S100 and become the new king of the premium compact camera world--possibly by a wide margin.

The RX100 is the most compelling point-and-shoot announcement of the past few years, for quite a few reasons. Start with the sensor: Despite a body that's just a tad bigger than that of Canon's S100, the RX100 has a 20-megapixel CMOS sensor that measures 13.2mm by 8.8mm, about 2.7 times bigger than the sensor in the S100 (7.6mm by 5.7mm) and all of its similarly sized rivals. The RX100's newly developed sensor is still smaller than the ones found in APS-C-format DSLRs and the Canon PowerShot G1 X, but it's a much larger sensor than the ones offered in anything that can fit in your pocket.
In tandem with that much-larger sensor, the RX100's very wide F1.8 aperture should make it a standout camera when you're shooting for dramatically shallow depth of field and in low-light situations. Several F1.8-aperture premium compacts are on the market already--namely, the Nikon Coolpix P310, the Olympus XZ-1, and the Samsung TL500--but all of those cameras have significantly smaller sensors. In addition, the RX100 has a 3.6X optical zoom range (from 28mm to 100mm), which should make it a nice option for wide-angle shots and portraits.

The RX100 also looks to excel in capturing video, as the camera takes 1080p video at a smooth 60 frames per second, and it provides manual shutter and aperture controls when recording movies. On top of that, the RX100 borrows one of the best features of Canon's S100: a programmable control ring around the lens, which provides quick access to manual focus controls, shutter and aperture adjustments, and ISO settings (from ISO 100 to a relatively insane 25,600).

In addition to essentials for manual-minded shooters, such as RAW and RAW+JPEG shooting and peaking assist for manual focus, the RX100 has many of the automated in-camera modes that have made Sony's recent Cyber-shot models so fun to use for casual photographers, including a pan-to-capture Sweep Panorama mode, an exposure-bracketing Handheld Twilight mode for shooting in the dark, an "Auto Portrait Framing" feature that automatically recrops portrait shots to fit the rule of thirds, and a 10-fps burst mode at full 20-megapixel resolution.

The camera has a pop-up flash, a sturdy-feeling aluminum body, and a sharp 3-inch LCD screen with 1.2 million dots of resolution. Sony says the RX100's newly designed battery is rated for 330 shots per charge, an advantage over the PowerShot S100's 200-shot battery. Like the S100, the RX100 sacrifices a bit of expandability to achieve its pocketable size, as it has no hot shoe on top for external flashes or microphones.

Sony is billing the RX100 as "the professional's compact camera," and all of that high-end hardware will come at a premium price. When it becomes available in July, the Cyber-shot DSC-RX100 will sell for $650, making it one of the most expensive fixed-lens cameras we've ever seen. You can get an entry-level DSLR or a compact interchangeable-lens camera with a kit lens for that price. When it comes to pocketable fixed-lens power, however, this camera looks like it will be the cream of the crop.

When and how to photograph the annular solar eclipse



(Credit: NASA)


On Sunday, May 20, at 5:30 p.m. PT, millions of Americans will witness an annular solar eclipse. In this unique event, the moon will cover only 94 percent of the sun, creating a spectacle worth capturing.
Unlike the common solar eclipse, the annular solar eclipse results in a ring of fire you may only catch twice or thrice in your lifetime. The last annular eclipse appeared in 1994, and NASA projects the next to occur in 2023.
Weather permitting, the full extent of the eclipse (including the ring of fire) will be visible in Asia, the Pacific region, and parts of the United States (like California and Texas). Other parts of the U.S. will still be able to view the eclipse, but will miss out on the unique ring of fire.
Sadly, the East Coast will miss out on the event entirely.
To find out when the eclipse will peak in your area, use this free tracking tool. You'll also want to find out if the sky will be clear during that time. (A few passing clouds are OK, but you won't be able to see the eclipse with an overcast sky.)
At its peak, the ring of fire will last about 4 minutes, giving you plenty of time to get a snapshot of the event. I consulted with CNET's photographers, James Martin and Josh Miller, to bring you this guide.

Step 1: Know your sun safety

In no circumstances should you look at the sun during the eclipse (or anytime for that matter). Even at its peak, the sky will still be very bright, since the sun will only be partially covered.
Likewise, it's not recommended that you point your camera lens at the sun, as its bright rays can fry your camera's sensor. At your own risk, you may be able to get away with pointing your camera at the sun during the peak, but otherwise, you'll need a solar filter.
Solar filters are simply placed over your lens to protect the camera from the sun and filter the rays. Unfortunately, however, it's likely that most photography stores are sold out of solar filters.
Alternatively, you can use No. 14 welder's glass and hold it in place. Call your local hardware store to see if it carries it.

Step 2: Grab your equipment

If you have a tripod, use it. Doing so will allow you to position your camera just once so that you can focus on other things, like adjusting your settings (which we'll discuss next).
Most importantly, use the right camera. Compact, or point-and-shoot cameras, are not good for this application since you (usually) can't tweak settings like shutter speed and exposure.
Instead, use a dSLR camera. If all you have is a standard kit lens, that's fine, but if you have a telephoto lens, now's the time to put it to use. The sun is nearly 93 million miles away, so even with a 200mm lens, it will appear small.
If you don't own a telephoto lens, you might consider renting one from your local photography store.

Step 3: Use the right camera settings

As the peak of the eclipse approaches, adjust your camera to the following settings:
  • Shoot in raw mode
  • 100 ISO
  • F 8.0
  • 1/1,000 shutter speed
  • Set to manual focus, and focus to infinity
The above settings are a rough estimate, but a good starting point. They're designed to prevent too much light from blowing out the photo. The fast shutter speed will ensure that your lens doesn't let too much light enter, and the low ISO will make the image less bright, allowing you to capture the moon.
These are not definitive settings, though, so adjust up or down in small increments as necessary. You'll have about 4 minutes when the eclipse is at its peak to adjust the settings, so don't panic.

Step 4: Shoot

As the eclipse approaches, you'll want to monitor its progress. Do not ever look directly into the sun, nor should you look in your camera's viewfinder without the proper eye gear. Special "eclipse glasses," No. 14 welder's glass, or a pinhole projector (instructions here) are a few ways to safely monitor the eclipse.
When the ring of fire appears, start shooting. During the 4 minutes of this event, tweak your camera settings as necessary, but avoid looking directly into the viewfinder, as you can seriously damage your eyes.
As the moon cruises away from the sun, take a look at the ground. The eclipse will produce beautiful crescent shadows, creating a scene you'll want to capture with your digital camera. This is a great opportunity for those with nonmanual point-and-shoot cameras to take advantage of the event as well.

Step 5: Edit

Unless you have a telephoto lens with a great zoom range, the eclipse will likely appear very small in your photos. So before you go sharing them on Facebook, process your photos in a program that can handle raw images, like Photoshop or Lightroom. (If you didn't shoot in raw, any photo-editing program will do.)
Crop in closer to the eclipse and make any necessary adjustments before exporting the image as a JPEG.
Have fun! Just remember: safety first. Never look directly into the sun, and never point your camera lens at it without the proper filtering equipment.
