Quote: ...were innovative camera, then why people does not buy pentax rather nikon and canon?
Because many people indeed are influenced by advertisement, promotion, commercials...
And DSLR newbies tend to go to a store and ask the staff to show them the latest Canikon which they know from TV or magazines.
Pentax is for "informed" people, who know exactly what they want and who want value for money.
I don't say that Canikons are "bad" cameras, but I think it is true, that they tend to cut down features on cameras to keep the gap between models. When I get the impression that a feature is left out, because of production cost, then so be it, but when I get the suspicion that features are cut down, so that the next higher model has one advantage more...
I hope Pentax will stay the same (100% Pentaprism even for lower-mid range for example).
