Originally posted by elliott who in their right mind would go for the FF with a crappy viewfinder, slow processor and less convenient controls?
1) Soccer mom who wants to have a 'pro' camera
2) People who have no idea what makes a good camera and just listen to the salesperson (but this one is "full frame", wow!)
3) People who have more money than sense
4) People who want to keep up with the newest fad
5) People who need FF for some reason (or think they do) but cannot afford a top end one
In short lots of people would do that, and indeed do that with APS-C cameras. Go to any event with lots of soccer moms and you will be stunned how many DSLR's you see. With the kit lens, the pop up flash being used to take pictures 100' away and being focused using live view at arms length. $1,000 worth of camera gear and they would probably get as good a picture with their cell phone.
So it is not a big leap from people who should be using cell phone cameras but are using DSLR's to people who should be using a P&S but buy a FF DSLR.
