Oftentimes on this forum, I read comments that imply that the only thing average consumers care about is more and more megapixels. That other features don't matter. But, really, people care about megapixels because that is what manufacturers told us to care about during the early years of DSLRs. It made sense at the time because the technology was developing rapidly and the sensor advancements from generation to generation were significant.
true, and at the time (for example, from 8 to 10), a megapixel jump told the essential story of realizable, end-to-end resolving power and also represented the technology frontier.
Now as the technology matures and resolution becomes less important, manufacturers are looking at other features to differentiate themselves.
I would draw a distinction between megapixels and resolution, and suggest the differentiator should really be end-to-end system resolution, not just the number of megapixels or the theoretical resolving power of the sensor. Marketing departments should express end to end resolution in a way that is easy to understand, and that includes the capability of the LP filter and the processor as well -- some metric that would differentiate two cameras in a 10 second elevator speech. Maybe it is "effective pixels" I don't know, but some way to express the capability of the entire technology chain.
I've never thought that much about weathersealing. But as with any successful ad campaign, this one certainly caught my attention and got me thinking about the advantages of full weather sealing. Now I want it in the 7DII and I didn't even know I did. Good marketing.
nice observation! now I want it more than I did before, and I want full 1D4 capable weather sealing
The point here is not to turn this into a discussion of the pros and cons of weathersealing, or to do a big comparison between the various levels of the current 7D, 5D and 1D, but to point out that the conventional wisdom that drives many of the discussions on this forum can be quickly upended by what happens in the marketplace.
no kidding. and maybe as the actual number of pixels within the sensor become only part of the story, perhaps we will see some creative marketing on Canon's part, and I for one am looking foward to comparing the vision in my head of what the 7D2 should be, with what Canon sees and actually produces!
