I read here many reviews that tell of sharpness problems. I could with my camera, with which I have now made more than 10,000 recordings, not confirm. However, some lenses require AF fine tuning, which has built the 70D fortunately and contrary to the 700D. Especially in need of correction is the EF50mm here often mentioned f1,4USM. While many lenses do not require correction with me, the others are between -3 and +5, the 50s, however, at 1.4 +13! After the correction is good, although not quite perfect, because this is a very old 50's construction. So if you have the sharpness adjustment is not carried out, which should send in his camera and never write here not slating. And if slating, then rather than the 50mm f1.4, the 70D can not help it namely often. Who wants to have a really sharp 50 should wait for the Sigma, but which is probably how my Sigma 35mm F1.4 A also need adjustment, preferably with the USB dock of Sigma.
The AF of the 70D is even very remarkable, so I photographed birds in flight with a 300 f2.8 and 1.4x extender, the results were as good as those of the 5D Mark III, even at speed changes of AF was excellent afterward. Even at full continuous shooting speed.
The video Af is already outstanding, the only thing that the camera can not, are continuous shooting moving subjects in Live View mode, but that's what the phase AF when folded down mirror.
I'll be happy to use the camera on and can you recommend any discerning amateur or professional, who manages with APS-C. The WLAN implementation is very mature, the camera is now also supported by the Android app "DSLR Controller", which still is more fun than work with the Canon's own.
