Originally posted by mikemike I am shying away from the K-x because with only 12 MP because it would bring me up to the next print size (11x14) but it would still face the same problem. with 15 MP k-7 I'm hoping that I might be able to pull of a 12x18 with a great shot and feel comfortable that even with some cropping any shot would come out nicely on either 11x14 or 8x10.
I'm sorry Mike, but I think you are wrong on the Megapixel / print size thing here.
I started out with digital in 1999 with a Olympus 2.1 Mp camera.
I still have several A4 (297 mm x 210mm) prints that look absolutely acceptable.
The resolution difference between 12Mp and 15Mp is neglectible. Specially if you consider that many photos suffer from a little motion blur or out of focus issues.
Nevertheless, let's do the math on image size:
Horizontal # pixels = Sqrt (Mp) * 1.5
Vertical # pixles = Sqrt (Mp) / 1.5
So, the difference on the horizontal resolution between 12Mp and 15Mp is:
Sqrt(15,000,000) * 1.5 = 2582 versus: Sqrt(12,000,000)*1.5 = 2309
That is 11.8% increase only.
