Another debate on sensors, and now Nikon is / or is not crushing Canon's sales because of it. The sensor is just a small part of the big "picture", so to speak.
If you haven't figured it out by Canon's actions with DSLR's in the last few years they seem to think Video is the future.
I doubt the sales lost or gained from Nikon are significant compared to the sales Canon lost to the iPhone and other phone manufactures. Canon should have gotten a clue from these companies. Where are the Canon phones built in to their cameras? The dedicated P&S is dead, add a smart phone to the back of it and people will come back. I would think seriously about buying a T5i phone, it would be smaller than bag phone I had in 1988. How about a new M model 1/8" wider with an iPhone on the back. I might pre-order.
Sensors, who's is better? Unless Canon sensors crash I don't care. I have my good glass, in a year or two this debate will be about a completely different set of specs on sensors and I will still have my good glass.
It's a good point about good glass. That's the reason I spent over ten grand on the EF 600mm lens. But there is a cost do buying good glass...the system has to last. If the onslaught of racing technological improvements in the CMOS Image Sensor sector continues, Canon's sensors will become irrelevant in a few years. Image quality took a jump with the D800...what happens when even your smartphone camera can achieve dynamic range like that, and every DSLR except Canon's does even better?
All anyone is saying is that Canon needs to step up their game, broaden their focus, and compete more effectively on multiple fronts. Dynamic range also doesn't just apply to stills photography, either. Canon is a new entrant to a fairly well established digital cinematography market. Again, sensors for the cinema segment are also improving. Red demonstrated a cine-sensor with over 20 stops of dynamic range! Sony has produced numerous smaller video sensors with incredible dynamic range (although nothing yet that quite compares with 20 stops). The sensor IQ debate doesn't actually end with stills, it is a video factor as well (and in many ways, DR is FAR more important for cinematography than it is for stills.)
Will Canon actually succeed in the video market? What'll happen when their cinema line remains stuck at 12 stops of DR while all of their competition continues accelerating to 20 stops and beyond? If the future is video, then Canon still needs to compete, and DR is still a factor. I hope they figure that out and do something about it before their (rather diverse) competition crushes them. I've invested too much.
What will happen when my smartphone is as good as my 1D? I will be buying a smartphone adapter for my 500mm, and carrying a few less pounds on the airplane.
