I got a call from a fan of the site today asking Canon 6D vs 70D.
And anytime I get asked a gear question I usually have to find out what kind of use the camera will get before I can answer. Which means, your answer may vary as well. But I wanted to sum up our conversation in a post.
I can understand the dilemma between the two cameras. I believe it comes down to two questions. Are you shooting more photography or more video? And if video, how important is continuous auto focus? The 6D is full frame, which means less noise in low light, higher ISO without noise. And uses manual focus for video, which most pro DSLR video shooters are used to anyway. The crop-sensor 70D will be great at auto focus video and will focus MUCH faster in live view than previous cameras, due to Canons new cross-type sensor.
The 70D ships with kit lens options that have STM, which means silent auto focus during video. But apart from that feature they are still kit lenses. f/3.5-5.6 isn’t that great and certainly not as pro as an f/2.8 or better lens. (Remember the lower the f-stop, the more light is captured = less grain in video.) However the 24-105mm f/4 L lens that ships with the 6D is quite nice even with f/4 and the combo will produce better images than the 70D with the kit lens. An optically superior photography lens for the 70D would be Canon’s 15-85mm f/3.5-5.6. Huh? Yeah it’s got better optics. It’s confusing I know, but some lenses with the same f-stop range are better than others. Do your research. Read reviews. Try in-store before you buy. Some lenses are ideal for full-sensor cameras, while others are meant to be used with crop-sensor. And many pro shooters prefer prime lenses, you get lower f-stops.
The x-factor in this decision would have been if you shoot wildlife or macro. The crop-sensor 70D would have the advantage. That extra 1.6x factor makes any long wildlife lens have even more reach, and adds magnification to macro photography. Hopefully he’ll come and share which way he’s going and why. One deciding factor will be when the 70D is released in September and we start seeing some comparison tests done.
I personally want a crop-sensor camera as a 2nd camera for macro, sports, and wildlife photography. The new 70D is quite tempting to me. But as one’s only camera, I really have appreciated the image quality from upgrading to full frame 5D mark 3.
