You know, I'm always amazed at just how much detail you can get out of a 6MP camera, such as my D50.
Full Size.
I can't get over the detail in the shirt.
I could get a 44x66in print out of this, while still looking decent at ~4ft away, and most certainly a 33x50in print! It would look beautiful at 22x33in!
So, what is the purpose of 15.1MP, or worse yet, 18MP with a crop sensor?
If my 6MP camera can make beautiful prints at 22x33in...................
Personally? I think camera companies are wasting their time pushing in more pixels. It's useless (often a negative) until you up the sensor size (which would need more pixels to maintain the same fill factor).
The camera companies must know the general public falls for the 'more MP is better' argument. Sad, but true.
I maintain that anything over 8MP with a crop sensor is pretty much useless. At that point your limiting factor is the lens and sensor size.
If anything, I think this is a testament to just how nice the 4 year old 6MP nikon's were.
