Getting back to the original post:
Originally posted by Yuri Leo I'm new here, guys, but I'm surprised by the fact that most forum members are sure that after buying expensive equipment, their photos will be better.
This is fundamentally incorrect, and demonstrates your lack of understanding of the culture of this forum. MOST of us fully understand that great photography comes from the photographer, not the gear.
What you don't seem to understand is that this is a PENTAX forum, not (only) a photography forum. The gear is sort of the point.
There are some expert photographers here, many unambitious hobbyists, and and a consistent stream of beginners. Some of us enjoy using the cheapest, oldest lenses they can get their hands on. Some of us enjoy seeing what the new stuff offers, and can afford that luxury. If that offends you, I would suggest you are the one with the problem.
Hang around for a while and maybe you'll get it.
