I don't own a single supported lens. They want me to spend a lot of money to submit work, for which I won't be paid. I do own a 21 ltd. but since I bought the K-1 I don't use it much,. Also, the K-1 is the only eligible camera I own, so I guess I could submit 21 ltd images taken in crop mode.
Also of interest, there are no flagship APS-c models listed. That's just odd.
I guess they are only taking images taken with premium gear in the current catalogue.
It does speak to the fact that Pentax doesn't really want to sell the 28-105. It's obviously a crumb tossed out there to draw people in to the store, and give salesmen a chance to upsell. I can hear the store dudes now, "Hey we don't have any images taken with the DFA 28-105, but look at these images taken with the 24-70." I see how this works.
The contest speaks to the current Pentax mindset. "Sell fewer lenses of higher quality for better profit margins."
