K20D is the top offering from Pentax, not even matching the D300. nuff said about pentax keeping up. i've seen your pics, you could have taken them with a pinhole for christ sake. i'm talking "grab the moment or get the shot or you get sued by the customers" kind of photography here.
a BW panoramma is not going to prove anything about the sensor, and a pannoramma isn't going to prove anything about the camera's AF system. i congratulate you for using you camera however, it;s nice to have a talk with another fellow photographer. you are right, you can make art with just about anything, it all depends on what kind of art you are planning on shooting.
for Sharkonweels:
my friend, we are not even in the same class in terms of photographic knowledge and experience, so ill only say this to you:
as a photographer, my goal is to sell useable prints, not 3 year old technology, or 2 days old tehcnology for that matter. my clients seem to enjoy them quite alot, so those old CCD's still have some cards up their sleeves. or, if i don;t sell the prints, i use those pics for my own enjoyment, and they do the trick every single time. the price you pay for those IS lenses it's the price you pay for top notch quality of construction, of the image, and maximum image stabilisation. there is no such thing as a free meal
and i did shot in the light rain and snow with the D80. can you shoot in the rain, with the 18-55 attached ? or the 50 1.5 or..
yes, they are the pics of a happy couple. the ones that i selected, and the ones i could upload, once selected, are quite average, i sorta selected them on the run. i don't even claim that the D80 is something unseen or unheard of, it is just a camera that does all the things i require from it.
as i said, i don't consider the D80 superior to the K20, or the K10 for that matter, i just think that for it is a very viable alternative, with a safe AF system, and it does what it supposed to do. and, if i need a good lens i can get it, IS or no IS, f/1.4 or f/3.5-6.7, 50 or 3500 dollars. and if i need a better body, and so on.
there are alot of things unsaid about the pics i just attached, in that youtube film you might have noticed multiple flash sources. easy with nikon, i raised the internal blitz, set the 2 SB's on slave, TTL, and fired away, with settings changeable in seconds. it;s all there, and alot more, that is unsaid. an experienced user takes alot of these factors in calculation before making a decision.
