Well done to Nikon for their great market research team! For many years, PnS cameras have started from 3megapixels to the recent 12 megapixels, and this is what PnS user will look at each time they upgrade their camera. And with this new 24 megapixels entry DSLR, they will be able to attract new PnS user to upgrade to DSLR.
But just to warn new DSLR user who wants to go for this camera, think properly, higher megapixels means bigger file size, and means bigger capacity SD card, need to upgrade HDD and computing power. But what is the purpose of a large megapixel photo if the only thing you do to the photo is to post it onto Facebook or if you print the largest size is maybe 8R? Do you really need the large file as how many of the new DSLR user can afford a photoshop software, and how many of them wants to spent time to do photo editing?
I really find that there is really no reason for buying this camera, as you are going to spent more money on storage, and computing power.
Just my personal opinion. I am still a strong Nikon supporter, I am waiting for a D7000 upgrade, I want more video features upgrade to it, hope Nikon see this... haha... thank you.
