I would like to the hear the argument for a clear distinction between a Pro and Amateur photographer. The former makes a living and the latter takes photos???
This says nothing about the quality of the images regardless of intent.
Pro photographers can get locked into a specific genre ie Weddings
or sport
and not show a glimmer of real creativity beyond the specific scenario, whereas amateurs can explore the medium for good or bad.
The gear amateurs use is largely based on cost rather than pure excellence and of course favours the Pro in terms of outright specifications.
However, Pentax have provided a means of bridging this gap over the decades ie, K1000, K20D to K-7 via LX and as a result have a dedicated band of adherents, I am one of them.
If the K-7 lives up to it's specifications it will be another landmark in the Pentax history of innovation and excellence and the individual, Pro or Amateur, is presented with a challenge to use the tool to it's greatest advantage.
Take Care,
