Because the cameras we’ve listed feature optical zooms, there’s much more flexibility than with most camera phones. Look for 3x optical zoom or more. A 25-100mm lens offers 4x zoom, as you might expect from the maths. The smaller the mm, the more wide-angle the effect, and the higher the number, the more telephoto. In other words, as you zoom in, the lens switches to the higher end of its capabilities. A higher zoom means you can get closer to the action, handy for sport or wildlife, say. (Digital zoom is different from optical zoom, by the way. In fact, all that happens when you zoom in digitally instead of optically is that you crop to the centre of the image. This means you’re creating an image with far fewer pixels and therefore a much less impressive result. Digital zoom = bad, optical zoom = good.)

Tough cameras can shoot single still images or bursts with zero or minuscule shutter lag. Most have autofocus adjustments that can hone in on a single object or keep a moving subject in focus. Lightweight and Compact Another piece of good advice for photographers who will regularly shoot in situations where dust, sand, and moisture are factors, is to consider purchasing an extended protection plan for your camera equipment. Offered by many manufacturers and camera retailers, these extended warranty plans come in all different levels of coverage and types of repair services. If you know there’s a high probability you might end up with dust or moisture in your lens or camera body, it may be worth paying a bit more upfront for the peace of mind later on. A set of 3D-printed lenses that are smaller than a grain of sand but can mimic eagle-eye vision came about thanks to a chance discussion with a colleague and the freedom to pursue scientific creativity, according to its inventor.

The Olympus has more flexibility in file extensions you can save photos and video. Olympus can save photos in raw and jpeg and movies in three file extensions not available in the Nikon: mov and mjpeg, avi.

Center for Information Technology Policy Promoting informed discussion of digital technologies and their role in society To all Sigma lens owners: Sigma Photo in Ronkonkoma is the "only" certified Sigma repair center in the U.S. In other words, all those techs that claim to be Sigma certified are lying. That's not to say that there aren't good techs out there who can do a great job repairing your lens, there are, but they are not Sigma certified (according to Sigma). In the perfect circumstance, you would have housing to protect your gear, whether it be a designated cover or case or even underwater housing (underwater housing works perfectly in sandy conditions). Regrettably, you might be in a circumstance where you do not have professionally designed protective gear available to you, and will have to make do with what you have.Other ultracompact metasurface lenses have suffered from major image distortions, small fields of view, and limited ability to capture the full spectrum of visible light — referred to as RGB imaging because it combines red, green and blue to produce different hues. We’ve moved object detection on-device (people, animals, vehicle) and added a cutting-edge TPU chip, which allows algorithms to run on 2 times more pixels, up to 7.5 times per second. That’s a fancy way of saying that the new Nest Cam (indoor, wired) can detect events more accurately and send more timely alerts. From reinforced compact models to all-out action cameras, we’ve tested the best waterproof cameras to help you find your ideal camera to make a splash with. The buying guide below features a range of recommendations to suit every skill level and budget, so whatever you’re shooting, you’re sure to take great images underwater or poolside. Panasonic's new Lumix TS7 (called the Lumix FT7 outside the US) is the latest waterproof camera here. As opposed to Olympus, which reduced the resolution of its TG-5, Panasonic has gone the other direction, increasing the pixel count from 16.1MP in the TS5 / FT5 to 20.4MP in the Lumix TS7 / FT7. Lens coverage remains the same as its predecessor, with a 4.6x zoom range that covers 28-128mm, but interestingly, the lens loses its Leica branding.
