Ah, what is 'better'?... Your K-7 will still be usable but some cheap beginner camera, though fragile and basic, might produce images heaps better in a couple of years time.
I see what you want to say, but even 6 years after, I still look at my son's photographs, taken with a small Minolta's A1 camera which had such an excellent lense, and they're full of life, detail and charm. I revive in myself every of those moments.
There's nothing I could do to better them now, for those moments are never to happen again.
For camera doesn't create images -- it only ignites our memories and we replay all of those moments inside, again and again.
