Originally posted by redpigeons but get this... I went to B&H and asked the guy at the Pentax booth "so why Pentax and not Canon Nikon?" ... so get this ... that was his answer:
"why some people get porsche and Ferrari and some get ford?"
Years ago, when a Chevy sedan sold for perhaps $3000 and a Corvette sold for about $7000, I read that someone asked Enzo Ferrari what he thought of the 'Vette. His reply was "if we sold it, it would cost $50,000".
I think that, if the K20D had the Canon or Nikon name on it, it would sell for $1,800, instead of $800. And, even at that price, people would be marvelling over what a bargain it was.
You always have to remember that Canon and Nikon sell many more cameras, so the stores prefer them; they're easier to sell. Plus, I've heard that the big two sometimes offer commissions directly to the counter salesperson, which Pentax doesn't do. The same is true for camera magazines that review cameras. C & N spend several times as much on advertising as Pentax does, so their reviews are sometimes a little suspect.
My advice is to go to the stores and try out the various cameras. Read the reviews and study the specs of each camera. Then, buy the one that is right for YOU, not because of some review, or because you saw Ashton Kutcher pushing the D90 on TV, but because the camera has the features and quality that appeal to YOU.
Don't worry about bogus analogies between Ford and Ferrari. Don't worry that you see a lot more Canons and Nikons than you do Pentaxes. The things I like about Pentax may not appeal to you. To me, the image that the camera produces is more important than the nameplate. Price is a consideration, and in that area, I think that Pentax gives you more bang for your buck than the others.
A Ferrari may go faster than a Ford, but if you want to carry a family, if you are concerned about price, if you are concerned about gas mileage, if you are concerned about ride quality on rough roads, if you are concerned about luggage space, a Ford may be more suited to your needs. My point is that just as Ferrari has its strengths, so does Ford. N & C have their strengths, Pentax has its strengths. All will take good pictures; probably better than you can.
BTW, be glad that you even have a store where you can go to the "Pentax Booth". Many of us outside of New York have a hard time finding a store that has any Pentax gear in stock.
