What to buy Canon SLR EOS 50D or Nikon D300?
I want to buy a DSLR to shoot a variety of topics … animals, people in motion. I definitely want the best pictures I can get for my money and felt the Nikon was slightly better than Canon, but now I'm listening to something else. I like to look through the live view screen in front of the viewfinder and I like shooting with natural gas before the light flash, but still want a good quality flash. I reduced over the cameras, how I can choose between the two models?
This site shows these cameras side by side two: http://www.dentonimages.com/cameradb.php?camera% 5B% 5D = 14 &% camera 5B% 5D = 3 & submit = Compare selected + + Chambers The fund, the D300 is an excellent camera, tested. It is a year old now, and will probably be replaced sometime in late 2009. 50D is brand new, but on paper seems to have more resolution, possibly better low light capability, but not as good autofocus, metering, etc. It all depends on what is needed for – action shots, etc go to the Nikon ruggedness. Details landscapes, portraits etc go to the Canon.
