Re: Are you looking at per-pixel-sharpness??

As I, and some others, have said before, upsizing the 20D image to 12mp would be an unfair comparison.

The 20D is an 8mp camera. It was designed to be an 8mp camera. All the circuitry, firmware algorithims and/or whatever all the stuff is that makes the camera tick is designed to make an 8mp camera work correctly. The D300 is a 12mp camera and is designed and programmed to make 12mp pictures. I'm certain that the D300 can make very nice pictures, but it's not a magic camera. It has weaknesses, just like any other camera.

Arash can correct me if I'm wrong but I believe that he has no intention of bashing the D300 just for the fun of it. I think he's just trying to show that the camera has weaknesses/limitations. I also believe that he's just trying to advise people to make a careful consideration before buying the camera so that they know what they're getting.

Way too many people buy into the hype about a new camera and rush out to buy one before really scrutinizing what the camera will or won't do. It's a lot smarter to realize that all cameras have weaknesses/limitations and that you should have your eyes wide open when looking at the images a camera will produce, and the features it alledgedly offers.

Nikon advertises the D300 like it's the best thing since sliced bread and a lot of fanboys build it up like it's better than God. Canon fanboys do the same thing when a new Canon camera comes out. Actually, fanboys go crazy about a camera way before it comes out. That is just plain stupid and unrealistic.

What Arash's comparison really shows is that a crop sensor is being pushed to or beyond it's limits at 12mp. 10 mp would probably be more realistic and logical for that size sensor. The megapixel war is pretty stupid.

I can't help but wonder what the camera manufacturers are going to do in a couple of years. They have already pretty much maxed out the abilities of the current sensors, so they're going to have to come up with something totally new if they're going to keep increasing megapixels and still have cameras that produce good images.

In the meantime we'll all have to live with whatever cameras we choose and it's nice to know that all the DSLR's will produce great images in the right hands. Some may do it just a little better or faster than others. Just be realistic about your expectations from a camera and do the best you can with what you've got.

Of course it's easy for an 8MP sensor to be better at
per-pixel-sharpness. Especially at higher sensitivities.

If you really want to see how the details match, upsize the 20D image
to 12MP. It goes softer and - bang - there goes the impression of
better sharpness and more detail. Try it. Even if you don't "believe
in it".

I have an utmost respect for the 8MP Canon sensor and I really think
it's one of the best all things considered. Even nowadays. But for a
12MP sensor the new Sony/Nikon sensor is quite superb. No, it's not
just Sony. And yes, Nikon's approach on NR is quite the opposite of
the Sony A700. You wouldn't believe it's the same sensor, honestly.
