hi,
im 20 this year.. not sure if im still considered as teen

.
my 20 cent worth opinion
teenagers nowadays just do not understand the true use of DSLR. i once saw a malay female asking a sony salesperson at the comex, 'How many mega pixel this cam has? have smile shutter?'
'er.. no smile shutter, and it's 14MP'
'no smile shutter? nvm... i'll get one'....... sales: 'er..do you want the body only or with the 18-70mm kit'
'what's 18-70, and what body only? nevermind, just get me one ' (moral of the story, she don't even understand lens let alone shutter and aperture. so why does she still wants it??? the A350 kit costs 1.3k...)
i shutted my ear after that sentence cause sony salesperson still drilling my heads. and when i went to the counter, saw her paying for it.
In another case, I saw teenagers strolling in groups, boys and girls (boys carrying the dslr), and they were shooting all the way, towards the sun and away from the sun w/o adjusting shutter or f-number, and they were using live view all the way!!! (obviously using the DSLR as a PS camera).
Conclusion,
there are teens out there using DSLRs as PS cameras, not using it to the fullest extend of creating quality image. instead of capturing time and moment, teens are using more of show off to friends, etc.
