Asus ZenFone 3 Zoom – Dual-camera, optical zoom and 5000mAh battery packed in just 7.9mm thickness

Samsung must take a clue or two from the newly announced Asus ZenFone 3 Zoom. As the name indicates, Zenfone 3 Zoom is a camera-centric phone but unlike other phones in this category, it is unbelievably super-slim.

A dual-camera module with optical zoom (and all sort of fancy optics) plus a huge 5000mAh battery are crammed with perfection in this phone – seriously kudos to Asus.

Dual Camera Setup

Dual rear cameras is the latest trend in high-end segment of smartphones. iPhone 7 Plus, LG G5, LG V20, Huawei Mate 9, Huawei P9 are some top-of-the-line examples of this dual-camera tech. ZenFone 3 Zoom is the latest addition to this league. It combines two entirely new camera systems – a 12 Megapixel ƒ/1.7 aperture, wide-angle lens with ASUS SuperPixel™ Technology is primed to capture everyday scenes, especially in dark environment; and a 12 megapixel 2.3x optical zoom for high-quality close-ups from farther away. Switching between dual cameras is very fast – you can either use a single one or the combination to enable the amazing depth-of-field (bokeh) effect. The camera glass is protected by Gorilla Glass coating.

New improved Tri-Autofocus (TriTech+) System

ZenFone 3 Zoom’s camera is powered by the latest Sony IMX362 sensor with large 1.4µm pixel size and 6-element lens. The innovative dual-camera system comprises two 12MP cameras, one with a f/1.7-aperture, 25mm wide-angle lens and a second with a 59mm lens. Users can instantly switch from the 25mm primary camera to the 59mm camera, giving them a 2.3X optical zoom (upto 12X digital zoom) that is perfect for portraits and capturing distant subjects. 59mm focal length lens is also the first ever in a phone. An improved TriTech+ autofocus system automatically chooses among three autofocus technologies — Dual Pixel PDAF, subject tracking autofocus, and second-generation laser focus — depending on the situation to achieve accurate focus in just 0.03 seconds, even when photographing moving subjects. Besides optical and electronic image stabilization (OIS and EIS) empowers camera to take blur-free shots and video every time. There is also a RGB color-correction sensor for true-color photography, and true 4K UHD video recording.

Asus SuperPixel Technology

ZenFone 3 Zoom is also the first ASUS smartphone with SuperPixel camera technology that enables it to focus incredibly quickly and capture clear photos at night or in low-light environments. ASUS’ custom hardware and software enhancements boost sensor light-sensitivity by up to four times by intelligently adjusting ISO levels while shooting and applying noise reduction in post-shot processing. Asus claims that the SuperPixel technology in ZenFone 3 Zoom camera enables it to capture 2.5 times more light than Apple iPhone 7 Plus and 10-times that of an average smartphone. Which means brighter and more colorful photos in low light conditions.

ZenFone 3 Zoom also supports Manual mode for pro-level controls in Camera. Manual options include one-touch control over shutter speed, white balance, EV, ISO and metering. Besides it also allows you to capture pics in RAW format and provides the ability to switch instantly between the dual lenses for either 25mm or 59mm focal length. Note that the claimed RAW support will be available with Android 7.0 Nougat.

Front (Selfie) Camera

Screen Flash feature turns the entire screen bright white for good soft illumination in low-light conditions.
