You might have only needed a 400mm lens on a crop but now you need a 600mm on a FF so it encourages sales of more expensive lenses.

That is simply not true. A 400mm lens on a cropped FF image is exactly the same as 400mm on a crop sensor. The only [current] benefits of a crop sensor is sensor/camera production costs, cropped image resolution, image, fps, and lens size/weight.
Cropped image resolution is a valid issue, but the 1Dx and D4 prove, for most people, that image is not about mp,
While the current D800 may be "slow" in that regard, I would be very surprised if the next iteration did not provide for 6+ fps, and I suspect the same will be true that Canon's first or second "big" mp cameras will also solve or come close to solving the fps issue.
thfifthcrouch said:Yes indeed the reach is achieved via a smaller sensor and more densely packed pixels. So the same reach can be achieved via a 40-50 megapixel camera full frame camera like the 36 megapixel Nikon. Such a camera's files would be a little unwieldy I suppose, where the crop frames of like 20 megapixels isn't.

No, in fact his statement is true. While it is true the lens produces the same image, the sensors do not see the same image. The crop sensor only sees a portion of the image. So while we know that you can crop an image with many FF and get about the same quality out of 7D sensor, the comparison does not stop there.
The framing of your image is an important difference between a crop and FF sensor. It is best practice to frame your shot as it needs to be framed rather than crop. It is better to practice this rather than approach a picture saying you will crop it. Another issue with framing is your ability to acquire a target. For me personally I found that a crop sensor on a 500mm body (800mm imaginary focal length) gave just about the maximum framing that I could use for hand held fast moving birds. The smaller window of view makes it more difficult to pick up the subject. For me the 1D IV sensor is about right.
So for me on a crop body I would not consider the 600mm, the FOV would bit to tight on a crop body and 500mm would be about right. For the 1D IV either a 500 or 600 would work. For a FF I would have to go with the 600mm.
So yes, going FF over crop sensor does drive the sales of the longer telephoto lenses.
A 7D II sensor that will produce superior or comparable IQ to a FF body would be of great interest. I doubt MintChocs logic that Canon would not release a high grade crop sensor to protect higher end lines. Instead I think Canon would jack the price of such a camera up and hope it increased sales of the 300mm and 500mm lenses
With a 400mm FF combo, not having it cropped in-camera gives you the breathing space to not 100% follow the action in the centre of the frame, and the ability to see outside of the intended frame to help find your subject
And, what about simply using a TC with a 400 on FF?
It would give you more breathing room. With the current version of the 7D there are many reasons that a 1D IV or a 1D X would be superior. Most of which have nothing to do with framing and cropping. The AF system alone makes the 1D IV a far superior camera. The low light abilities and the AF system of the 1D X make even more superior.
But there is a question, what if a 7D II sensor closes this gap?
As far as a TC, it slows down AF system and breaks down IQ. But if there is an argument that a crop sensor would cannibalize 600mm sales why would Canon release a TC that might do the same. It isn't going to happen.![]()

vscd said:As the 70D goes up into the more professional line (with sealings like a EOS1n, for example) the 7DM2 could really get missed. Maybe the 7DM2 had an older sensor with no DualPixel-AF and they underrated the success of the 70D-Sensor.
Afterall there were Rumours for Canon to get into Medium Format Sensors anythime soon, so maybe the Fullframe is the new Crop![]()

Here at Futuresource we expect the interchangeable lens segment to grow 5% in 2013, to reach close to 21 million units shipped.
Sales of the 70D are slower than expected,
vscd said:>yeah im already loving the canon MF lens lineup....
I guess you liked the EOS-M lineup, too. Didn't you?
It's no problem to kick the market with a Canon EOS-1DxS and a startingline of 75mm 2.8, 40mm f4 and a 150mm 3.5. The Lenses were calculated decades ago.

doesn´t look like "free fall" to me.

Quite right. My 300 f/2.8is is great for my purposes on the x1.3 crop APS-H 1D4 but if it was an all-FF world, I'd find myself forced into a 400 f/2.8isII purchase. If there is no 7D2, I may just stock up on good 1D4 bodies.MintChocs said:It's plausible, Canon are probably trying to steer people to full frame and protect their more expensive models.
