After the Canon EOS M10, also the Canon Powershot G5 X is listed at the Canon Direct Store. Product description:

Great Images Are in Your View

The first PowerShot G-Series camera to incorporate a full-featured 2.36 million dot electronic viewfinder, the amazing PowerShot G5 X camera makes it simple to compose, set and capture high-quality stills and video without taking your eye away from the camera. For photography in the glare of bright sunlight, recording HD Video in an auditorium and other situations where the lighting is difficult or using the LCD monitor is inconvenient, the PowerShot G5 X’s electronic viewfinder helps enable unfettered operation. Full control is made simple with dedicated dials situated around the camera that let you easily customize and control the settings. What’s more, helpful features like a built-in accessory hot shoe and a multi-angle, capacitive touch screen monitor serve to create an experience as unique as the subject being recorded. With its phenomenal and large imaging sensor, its marvelous electronic viewfinder and comprehensive operation, the PowerShot G5 X can deliver performance that’s easy to see.

Impressive Speed, Resolution and Quality

At the heart of the PowerShot G5 X camera is a brilliant 1.0-inch 20.2 Megapixel* High-Sensitivity CMOS sensor. Physically larger than the sensors found in most compact cameras, the PowerShot G5 X’s sensor works in tandem with Canon’s DIGIC 6 Image Processor to quickly deliver gorgeous, high-resolution images with nuanced details, plus impressive low-light performance with a low signal-to-noise ratio and minimal noise and distortion. Suitable for tremendous enlargements, significant cropping and many other applications appealing to the advanced photographer, images and video captured on the PowerShot G5 X’s sensor are engineered to impress even the most critical eye.

Dynamic Optical Performance for Excellent Results

To take advantage of its large, 1.0-inch imaging sensor, the PowerShot G5 X camera has a sharp and versatile 4.2x Optical Zoom lens. With a 35mm equivalent range of 24–100mm it’s equally suitable for landscapes, portraits, group photographs and even close-up photography. Designed to perform in numerous lighting situations, the PowerShot G5 X’s lens has a bright maximum aperture of f/1.8 for low light performance, a 9-blade aperture for beautiful, blurred background detail and is engineered to focus from distances as close as 2.0 in. The PowerShot G5 X’s lens works in concert with the camera’s sensor and image processor to reliably deliver sharp images from edge to edge and from wide-angle to telephoto, all tailored to meet the exacting standards of even critical photographers.

Sharp, Fast and Colorful for Optimal Performance

The PowerShot G5 X camera’s defining feature is its unique, high-definition electronic viewfinder. It’s great for photographers who prefer to hold the camera up to their eye, and is a veritable lifesaver in bright light and when composing on the camera’s LCD screen is inconvenient or overly conspicuous. Featuring 2.36 million dots, and with a wide color gamut, it provides a high-contrast, realistic and smooth edge-to-edge view for image composition, adjustment and review. Designed for sustained use, it delivers 100% image coverage, a smooth refresh rate up to 120 frames-per-second (Smooth Mode) and a flexible information display that can enable comfortable camera operation throughout the day. Its 22mm eyepoint delivers excellent visibility, even when wearing glasses, and a built-in eye sensor helps the PowerShot G5 X to transfer quickly between the viewfinder display and Live View on the camera’s LCD.

Take Control, with Ease

Designed for speedy operation while looking through the viewfinder, the PowerShot G5 X camera features a host of controls for quick, accurate settings and adjustments. Beyond its Vari-angle touch panel LCD monitor, the PowerShot G5 X features a front dial situated on the front of the camera for operation with the index finger, a top-mounted, thumb-operated exposure compensation dial, a rear-mounted control dial plus a control ring around the camera’s lens. Eminently customizable, each dial has an optimized operating torque that helps to identify it by feel, for sustained, intuitive and near-silent operation in quiet situations like weddings and performances.

Compact Performance, Easily Expandable

The PowerShot G5 X camera’s hot shoe enables expanded operations for advanced photography. It’s compatible with all Speedlite flashes for the EOS System, so bounce flash and multiple-flash photography is easy to achieve. Whether attaching a Speedlite flash or the Remote Switch RS-60E3 for long exposures or night scenes, the PowerShot G5 X’s hot shoe can help provide shooting opportunities far beyond the scope of most compact cameras.

Canon EOS M10 shows up at Canon Direct Store

Canon EOS M10 Shows Up At Canon Direct Store

The new Canon EOS M10 is listed at the Canon Direct Store. The M10 is available as kit with the EF-M 15-45mm f/3.5-6.3 IS STM lens. Three color options will go on sale, black, white, and grey.

The Power of an EOS Camera, Simplified

Step up to EOS camera quality in a simple and easy-to-use package! The EOS M10 camera combines a lightweight, compact design with the power and image quality EOS cameras are known for along with the versatility of interchangeable lenses. Inside is an 18.0 Megapixel CMOS (APS-C) sensor that’s paired with the DIGIC 6 Image Processor to help capture colorful, detailed videos and photos, even in low-light situations. To help expand creative opportunities, the EOS M10 is compatible with a wide range of compact EF-M lenses specially designed for EOS M series digital cameras, and the extensive range of EF* and EF-S* lenses used with Canon’s DSLR cameras. It also has easy-to-use and automatic settings like the innovative Creative Assist to simplify photo adjustments and help ensure your images are how you want them. Self Portrait mode extends that assistance to help you grab great selfies by adjusting settings that smooth skin tones and artistically blur backgrounds. If it’s too dark for a normal photo, a built-in pop-up flash lights up dark spaces. All these powerful features combine to make the EOS M10 worthy of your attention, while being conveniently wrapped in a slim, stylish camera.

Legendary Image Quality in the Palm of Your Hand
The EOS M10 camera features a lightweight, comfortably designed body that’s easy to hold and take with you. From overseas vacations to backyard family gatherings, the EOS M10’s compact size means it can easily be on hand, without getting in the way. A built-in thumb grip also lets you grasp the body securely, while the rounded edges make holding the camera easier when recording long video clips. All this while still featuring the image quality for which Canon EOS cameras are so well known.

Superb Detail With Minimal Noise
The 18.0 Megapixel CMOS sensor captures lots of detail with very little image noise. The sensor itself is APS-C type, which is the same size as the sensor found in Canon’s EOS Rebel series of cameras. The high resolution means you can crop the image to focus on one section, or have enough detail to print large photos to display or give to your family and friends. An ISO range of 100–12800 (expandable to 25600) lets you capture images on bright sunny beaches and darkened streets.

Fast Focus
Life happens fast, and there’s little worse than missing out on capturing that perfect moment because the camera was too slow to focus. The EOS M10 camera uses Canon’s Hybrid CMOS AF II autofocus system, which measures up to 49 different points in an image quickly and accurately to help get it in focus. In addition, face detection and object tracking help keep the subject of your photo focused, even if they move. What’s more, the EOS M10 is compatible with all EF-M lenses, which feature an AF+MF mode that lets you easily combine the speed of autofocus with the creative flourish possible with manual focus.

Get the Shot You Want, at Any Angle
It’s vital to see if you’ve composed the photo you want. The EOS M10 camera’s 3.0-inch touch screen has 1.04 million pixels, letting you preview images in high detail. It can pivot a full 180°, meaning you can capture a unique dog’s-eye-view of the world or flip the screen up to get that epic selfie.

Superb Moviemaking Made Easy
The EOS M10 camera can capture 1920×1080 Full HD video at frame rates of both 24p and 30p, and can record in MP4 format for easy sharing online.

Moviemaking Made Easy with Manual Movie Control
The EOS M10 camera is a fine moviemaking tool. With touch-activated AF and a number of manual controls available, it’s easy to make intuitive setting adjustments silently and on the fly using the EOS M10’s dials and touch operations.
