given the rumors are true and nikon is releasing a 36MP D800 im curious what new DSLR customers will buy. for years canon was raising MP and nikon was saying less MP are better.
now it seems the positions have suddenly changed.
If this is true then for the first time I will be considering adding Nikon to my setup. Sometime in the next year or so I would like to improve my ability to make large landscape prints from a single frame. An 18 MP 5D3 will offer me nothing in this regard over my 18 MP 7D. Cry noise and DR all you want. For low ISO landscapes printed big (>30") it's all about the pixel count.
The bummer is that Canon has the best T/S lenses and they scream for more MP. I couldn't care less about movie mode Canon! You need a high pixel count FF body for landscape and studio use.
most amateurs who have no clue still think more MP will make a better image.
even after years this is still stuck in their heads.
For some applications it is absolutely true. A 36 MP sensor will produce larger, more detailed low ISO landscape prints then an 18 MP one. No if's, and's, or but's.
Have you used the TS/E to produce a 3 shot landscape which you can easily merge into a pano which is close to a 36MP equivalent? For landscapes I have used this quite a bit. Not in every situation of course, but it works well, is quick to do the 3 shots and the stitching tends to be very clean just because of the way it is taken. No need for a pano-head...
I came across a photographer at the weekend, IIRC using a 5D. He shot a single photo using both 3 shot exposures and multiple focus distances and ended up doing focus stacking and HDR in Photoshop. I think the single shot was made up of 33 individual pictures. Again, does not cater for every scenario, but does illustrate that there could be some solutions that could work without the need for a higher res sensor. Horses for courses...
Ultimately, Canon has to chose what it thinks will be best for the majority of it's customers (current and future), and there will always be fallout. Given the D3X and the D3S, I am suprised that Canon has concluded that 18MP is the ceiling, but I guess people will decide when the dust has settled, the reviews are in, and we've hand hands-on experience with the new bodies.
