We are all fanboys or fangirls here (although I suspect there are far more boys than girls, unfortunately). Some are just honest about it.
Don't misunderstand. I think the 1D IV is a fantastic camera, if a bit out of my price range. But, acknowledging a camera to be great is different from misreading the many signals from the manufacturer about the future of the format.
I may be overly optimistic about the pricing and/or features of a 7DII. But, there is some logic behind my optimism. In a nutshell, it must appeal to a market that is much more price sensitive than the 5DIII. Because the market is mature now, it must also attract current 7D owners like myself if it is to succeed. I base much of my speculation on what I believe it would take to convince me and other current 7D users to upgrade.
I commend Canon for targeting the 5DIII to a specific professional market (wedding and event photographers) and for doing sufficient market research to know that the $500 premium would be worth it to these professionals for the superior ISO and noise performance. (As an aside, the D800 seems either not particularly well-targeted, or is targeted toward a much smaller universe)
Yes, I do expect to see some improvement with the next generation of APS-C sensor. The T4i is not a new generation, but appears to rather be the same generation as existing APS-C sensors with continuous autofocus laid on top. To me, the more interesting speculation is whether the 70D will receive the same sensor as the 7DII or if it will also receive the T4i sensor.
Perhaps I am just ignorant, but I do always wonder when people proclaim the virtues of larger sensors, just what they are seeing that I am missing. I have made prints up to 18 x 27 and even with my nose inches away from the print there is no visible grain or noise. People complain about issues that I have never had a problem with (banding for example). I've read numerous posts from successful photographers who readily acknowledge that neither they nor their colleagues can identify differences between sensors in a final print.
I understand and respect the opinions of those who prefer the bokeh of a larger sensor. But, that is a question of style, not of quality.
Just what is it that is so troublesome for some photographers that they feel they cannot get a good product out of an APS-C sensor?
