Canon EOS 70D, tried to preview - WebNews

Into The new Canon EOS 70D SLR is the latest of the many innovations introduced by the Japanese giant since last year, the anniversary of the 25th birthday of the famous EOS series. The commercial choice was to raise more segments, with special attention to innovation as evidenced by the mirrorless EOS M and the small but handsome SLR EOS 100D, each with unique features and able to give a welcome breath of fresh and renewal in the range .

Into The Canon EOS 70D in our country officially presented at a meeting organized by Canon Italy, which has finally allowed to see and touch live after the first official comunati released in the hours before . Although the machines were available specimens of pre-production, we were able to clear our heads of the main innovations introduced on the new mid-range Canon, for sale by the end of August at the price of EUR 1,184 for the camera body only.

Into In achieving this EOS 70D , Canon has held in high regard the feedback received from users, both amateurs and professionals, making it the natural evolution of the previous EOS 60D, mainly more versatile and capable in shooting video .

Into fact, you start with small improvements in terms of quality and shooting speed , together with a rationalization of physical controls, accompanied by the now indispensable articulated screen and touch , and ending with the new system of focus that, according to the technical managers Canon, it is not a point of arrival for this category, but rather a starting point for shooting video.

System Dual Pixel

Into The Pixel CMOS Dual AF system, which works in symbiosis with the renewed format CMOS sensor APS-C 20.16 megapixel , is specifically designed for use with the LiveView . The objective of Canon was to make the system AF more fluid, faster and, above all, more homogeneous in the transitions from a point of focus to another. How quickly clarified, it is a different system than hybrid – phase detection and contrast – which is on the small mirrorless EOS M, with target different usage, but mostly different performance.

Into In practice, in Dual Pixel CMOS AF you start with a phase detection system, in which each pixel we have two photodiodes that work independently, to return a more accurate and more reactivity of shooting with LiveView active, so photos and videos. So the pixels play a double task: to collect together with the main light, also work by detecting the phase difference of the light rays from which are affected, managing in fact the focus.

Into is natural to think that the Canon EOS 70D can have twice the resolution of approximately 40 megapixels, but in reality it is an approach born exclusively to optimize performance in focusing a with a phase detection system, by driving faster lenses in focus and making it soft transitions – in addition to being more precise.

Into Canon has made it clear readily another question concerning the non-use of all pixels to guide the Dual Pixel CMOS AF: To ensure the highest quality and yield, are used to only those who reside in ‘ 80% the central area of ??the sensor , even if they all work. The reasons are the usual ones, in other words, the difficulty of the pixels at the edge of the sensor to capture the light correctly, with high angles of incidence in arrival from the objective lens, and then provide a reading is accurate and responsive.

Into The real innovation is for Canon to have improved the speed of a phase detection system, especially when compared to one in contrast, slower.

Into The last question remained was clear from the outset: that of Canon EOS 70D is a system that works only when we use the LiveView and then observing and checking the scene from the screen and not with the optical viewfinder.

Videomaker

As we could see in our brief tests on pre-production models of the Canon EOS 70D , we finally have a DSLR with a ‘ user experience high-level, both in traditional and shots in a field hitherto neglected, that video footage, increasingly widespread phenomenon in the world of outdoor photography and, in particular, in sports and action scenes .

Here Into the new EOS 70D has shown a natural vocation, not only for the obvious accuracy and responsiveness of focusing a, and for smooth transitions, but also for the many video options: Full HD 1080p at 30, 25 or 24 fps, or 720p at 60 or 50 frames per second, always with stereo audio .

Into Taking a step back and remembering that it is also, and above all, a camera when you shoot looking through the viewfinder, Canon has not overlooked this shoot mode: the pentaprism has a coverage of 98% of ‘ framing with 0.95x magnification, the more data that is displayed on-screen and, above all, the ability to control how the focus without looking away, taking advantage also more ergonomic controls.

Into Finally, Canon has reassured us on maximum compatibility with the optical catalog , so as to make the happiness of all photographers with ambitions of film makers, who are looking for a relatively inexpensive solution to flank, perhaps, to a professional body, dedicated precisely to video footage quality.
