The Canon Greek deity 70D is that the company's latest enthusiast-oriented SLR. It replaces the Canon 60D, and has numerous enhancements that distinguish it from the likes of the Canon Greek deity 700D. The optical device is considerably larger, there area unit ample single-function buttons, a passive digital display screen on the highest plate and a command dial and rear wheel for direct access to exposure settings. It's quicker than each the 700D and therefore the 60D, with a 7fps continuous mode that lasted for 108 JPEGs or sixteen RAW frames before deceleration to the speed of the cardboard.

PHASE observe
The 20-megapixel resolution is Canon's highest thus far for associate degree APS-C device, and therefore the device style is radically totally different to something we have seen before. every pel not solely measures the intensity of sunshine, however conjointly the direction, with all created from 2 photodiodes facing left and right. This helps the device to perform phase-detect optical device, determinant not simply whether or not the image is focussed, but also, if not, by what proportion. It means that the lens will jump straight into focus instead of shuttle back and forth in search of a pointy image.
Phase-detect optical device is already accessible altogether trendy SLRs once mistreatment their viewfinders, however in most cases it's disabled in live read mode. The 70D's ability to perform phase-detect optical device directly on the device makes it a lot of quicker than the 60D to focus in live read mode.
We've seen this method a couple of times before, last on the Greek deity 700D. However, previous implementations are restricted to a couple of dedicated phase-detect points dotted across the device. what is special regarding the 70D is that nearly each pel will contribute to phase-detect optical device. The active space is quoted as eighty per cent of the frame, horizontally and vertically – you cannot place the optical device purpose right at the sting of the frame.

Testing with the 18-135mm memory lens, the profit was straight off obvious. It took around 0.5 a second to focus and capture a photograph in live read mode, rising to around one second in low lightweight. that is double as quick because the 700D, and regarding 5 times quicker than the 60D.
It's a excellent result, however we won't facilitate questioning if it may are even quicker. It usually took but zero.2 seconds from once we ironed the shutter button to hearing a double-beep to verify that focus was achieved, then again it took another zero.3 seconds for the shutter mechanism to kick in. Half-pressing to focus then totally pressing to capture removed this shutter lag, though. we tend to measured a pair of.1 seconds between shots in live read mode, that is far slower than the zero.4 seconds it achieved once mistreatment the optical device. It delivered 7fps continuous shooting in live read mode, however focus was mounted and therefore the screen was blank throughout bursts.
Still, rock bottom line is that live read mode is much a lot of helpful than on the other Canon (or Nikon or Pentax) SLR. It helps that the screen is articulated, with a side-mounted hinge that permits it to tilt up, down, to the facet and right around for self-portraits – a feature that is prominently absent from the Nikon D7100 and Canon and Nikon's full-frame SLRs.

The 70D's screen is touch-sensitive too, thus moving the optical device purpose in live read mode could not be easier. Subject pursuit is accessible however we tend to weren't greatly surprised by its dependableness. The touchscreen conjointly quickens navigation of the letter of the alphabet menu, which provides fast access to a wider array of functions than area unit lined by the dedicated buttons. The touchscreen provides an alternate thanks to navigate the most menu, however we tend to found it faster to use the command dial and rear wheel to leap to a selected setting.
The 70D is quickest once mistreatment the optical device, thus it's sensible to check some enhancements here too. The 60D's 9-point optical device device has been ditched in favour of the 19-point device 1st seen within the Greek deity 7D. All nineteen points area unit cross-type for accrued sensitivity, and that they were quick and correct even in very low lightweight. there is a new button next to the command dial for increasing the active space. the most important space encompasses all nineteen points, and once utilized in conjunction with the AI Servo optical device mode, permits for a few basic subject pursuit. It cannot match the sophistication of the 3D pursuit mode within the Nikon D7100, though.
IT'S ALL 'APPENING currently
Wi-Fi is constructed in, with constant functions that we tend to saw on the Canon Greek deity 6D. They embody remote via the incidental to iPhone and mechanical man apps, with access to exposure settings and therefore the ability to maneuver the optical device purpose mistreatment the smartphone or tablet's touchscreen. whereas the 6D had to form do with foggy live read optical device, the 70D was rather more responsive once shooting remotely. The app may also access the camera's card to look at full-screen previews with EXIF information, apply star ratings and instigate transfers.

We appreciate however each the remote shooting and image browsing modes area unit accessible while not lockup up the camera's controls. Photos appeared within the app among 2 seconds of being captured, belongings USA use associate degree iPad to review shots in additional detail that the camera's 3in screen permits. However, previews and transfers area unit restricted to a pair of.5 megapixels, thus it isn't thus helpful for checking focus. enabling Wi-Fi disables the USB port and video capture, thus a pill cannot be used as a far off video monitor. The iOS app worked fine in our tests however we tend to may solely connect our Nexus four smartphone via associate degree existing network instead of build a right away affiliation.

FOCUS ON VIDEO
The new optical device technology is nice news for photographers, however it's probably even a lot of exciting for videographers. The 70D's video optical device was the foremost responsive we've ever seen from a large-sensor camera, adjusting in but a second once we captive the optical device purpose mistreatment the touchscreen. There was no sign of focus searching, and face detection and subject pursuit helped USA follow moving subjects – though once more, it absolutely was alittle unreliable.
Even so, once we broached on a theme to target, a lot of typically than not, focus would stay bolted because it captive nearer or any. We've continually maintained that manual focus is that the solely thanks to accomplish polished results, except for the primary time, here's a video optical device system that we will create by mental act getting used in skilled productions. With a selection of twenty four, twenty five or 30fps capture at 1080p, clips up to half-hour associate degreed an All-Intra mode that encodes at 75Mbit/s to avoid compression artefacts, it all appearance pretty promising for serious video production.
It's a shame, then, that details within the 70D's videos are not alittle swindler. Its footage looked good enough in isolation, however the Panasonic GX7 and Panasonic GH3 were able to resolve fine details with larger fidelity. we tend to conjointly detected a bent for moiré interference on continuation textures like cloth and bricks. The full-frame Canon 5D Mark III showed massive enhancements in video detail compared to previous Greek deity cameras, however it appears that these advances haven't been engineered into the 70D. we tend to achieved higher results by choosing the Neutral image vogue and sharpening up the footage in package, however this did not get eliminate the moiré interference.
Canon Greek deity 70D sample shot it'll trouble some over others, however the Panasonic GH3 (left) encompasses a clear advantage over the 70D (second from left) for details in videos. The 70D's details is improved by rolling off the sharpness and distinction then sharpening in package, however it still cannot quite match the GH3 - click to enlarge
Another hurdle for serious video production is that the lack of a electro-acoustic transducer socket, that limits the quality of the mike input. The HDMI output will stream a live feed however it isn't a clean feed to send to associate degree external recorder. Despite the 70D's excellent optical device performance, the Panasonic GH3 remains our prime selection for video production. The 70D is not too so much behind, though. For a lot of casual users UN agency still demand top quality, its a lot of responsive video optical device could tip the balance in its favour.
