Okay a friend of mine has a D200 and if you scratch it,the repair is the price of a new camera since the mirror and sensor are together as one piece manner of speaking. Now the D100 they are both seperate. So my question is. Is the sensor on the D80 set up like the D200 or seperate like the D100?
No offense but if you are expecting to do any type of shooting that could get your sensor scratched then you might not want to get the D80. The D200 has a tighter built body and can no doubt take a lot more damage. It reminds me of a question I asked my girlfriend: "Do you think the D70 will be better than the D200 while I am shooting in the rain? The D70 is cheaper than the D200 to get fixed."
She said, "If you are planning on shooting in the rain then you already know the answer to that..."
Better to get a camera that costs more and won't break as easy than to get a cheaper one that may be easier to fix. Marine photographer Alexander Mustard doesn't shoot with a D50 cuz it is cheap. Picks up a D2x cuz it performs better and the underwater cases for it are better.
"The passion for photography doesn't come from the photographer... it comes from the human emotion... the moment that the photographer is in and their willingness and decision to capture it."
If I were to scratch my hotmirror (low pass filter directly ontop the sensor), I'd replace it myself for the cost of a new hotmirror. All I'd have to do is talk someone that has done an IR conversion into selling me the hotmirror that came out of their camera.
