Nikon Rumors is reporting that Sony will soon announce a 24mp APS-C Sensor which is likely to become the foundation for the next generation of the D300.
That got me thinking, will Canon continue to up the ante in the megapixel war, or will they, at some point, decide to shift strategies and open up a new front (increased dynamic range, improved high ISO, superior noise control)?
Certainly, they have the technology and expertise to keep increasing the megapixel count, but I wonder if they might decide that a more modest increase (say 22mp) in the next generation of APS-C sensors, coupled with an extra stop or two of speed and improved image quality might be more advantageous.
I'm generally a fan of more megapixels, but I'm beginning to wonder if there is much point to going too much bigger. With a native size of over 21 x 14 inches (at 240 ppi) the current 18 mp sensor is more than sufficient for most needs.
At some point, the trade off in file size outweighs the benefits of a native size that exceeds anything that even most professionals will ever need. (Yes, portrait, wedding and commercial photographers need the larger sizes, but most photographers shooting for publication, either in print or on the web, don't. And, yes, I know that folks like Macfly need the resolution for their work, but photographers at that level aren't ever going to be shooting with an APS-C camera).
Anyone who's read any of my past posts know that I am definitely not one of those "fewer megapixels are better" people. Frankly, I think that is ridiculous. But, I do understand the law of diminishing returns and I can't help thinking that we may be reaching that point.
I have tremendous respect for Canon's market savvy and I wonder if they might decide that they can really shake things up and gain a competitive advantage by taking the market in a totally new and unexpected direction.
