I've been thinking about Canon's release of the 6D, and the fact that it appears to be decidedly inferior to its apparent competitor, the D600, in almost every single way.
I don't think the D600 factored into Canon's calculation for this camera at all. Simply, it wasn't designed to compete with it. Rather, the 6D is Canon's attempt to design a 5D2 that's with a few extra selling points/gimmicks to attract beginners. It's a camera designed for those for whom a 5D2 (in 2012/2013) is 'good enough', who wouldn't benefit from either the 5D3 or a high-resolution version.
The 5D2, in its time, was a groundbreaking design - high resolution, video, a great screen for live view (far better than that on the 1Ds3). But I think even Canon was stunned at its overwhelming success. It likely wasn't designed for such high-volume production, requiring Canon's more advanced assembly lines and resources which cheaper cameras don't need. But, now, Canon needs those same assembly lines and resources to build newer, more complex models - yet the 5D2 remains popular and is more than enough camera for many beginners today. The solution? Come up with a new design, with performance similar to the 5D2, that's cheaper and simpler to manufacture. Enter the 6D.
IMO the 6D will probably settle around the $1600 mark, with the 5D3 settling around $2500 (the prices are down to $2745 already, and sales seem to have dropped off markedly after the initlal rush of people who would buy the 5D2's successor for any price - something that hasn't happened with the D800, which continues to be in great demand), leaving room for a high-resolution version in the $3500-$4000 range. Not unreasonable, given that Canon models tend to drop off in price more quickly after launch than Nikon models. In other words, Canon isn't competing directly with the Nikon models, but finding the gaps in between. The low-end 6D is situated well below the D600, the 5D3 is situated between the D600 and D800 (after all, on technical specifications, the D800 is superior in most areas, most notably the sensor), leaving room for a top-end, high-resolution, 16-bit-output 3D, or whatever name they choose, above the D800. Then, of course, there are the specialist sports/action cameras in the 1Dx and D4, but they are really in their own category.
It's a bit like the case when the 5D2 was released - sure, it was a great new camera, but it also cost USD$2700. The 5Dc was more than enough for many people, who didn't shoot video and didn't need 21MP, but wanted a full-frame sensor. If Canon had continued to sell the 5D at $1600-$1800, it would have continued to sell well, alongside the 5D2 (perhaps with a few extra tweaks, such as live view and AF microadjustment). But they stopped production of the 5D in order to make way for the new camera. With the 6D, it seems like Canon is trying to not let that happen again.
Any thoughts?
