If the APS-C sized sensor is so inferior to the full frame, as many people claim,why is it that Canon just introduced the EOS 7D?

Hi Pentaxian friends.

If I had a dollar for everytime someone told me that the APS-C size sensor that Pentax uses is not as good as a Full Frame sensor...well I would be rich by now. We hear the argument all the time that Full Frame is the only way to go and that "my next camera will be a full frame". The fact is that only 5% of the camera sold worldwide are Full Frame. That's not a big market and it is a market mostly used by Pros. The prices for Full Frame sensors will remain high because of the cost of making larger sensors from the same standard sized silicon wafers.

Why would Canon introduce a new (1.5 crop factor) DSLR? The EOS 7D is indeed an APS-C. DSLR. Since Canon now adopts it, does it make it any better? Furthermore, their new sensor is a CMOS with 18 mega pixels. I thought that the optimum and maximum effective mega pixels on an APS-C sensor was around 12 mega pixels!

It is obvious that Canon really believes that APS-C is the way to go for the consumers (the 95% of them that don't purchase Full Frame DSLRs).

To me, that reinforces my loyalty to Pentax. Why would a giant like Canon revert to APS-C sensors, just like Pentax? I bet you that sites that favor Canon (we all know who they are) will now praise the virtues of Canon APS-C sensors...Hello! Isn't it what Pentax has been doing all along?

Thanks for reading,
