LOWER IMAGE RESOLUTION - DUE TO THE SHORTER LENS/SMALLER SENSOR. ANYTIME YOU REDUCE THE SENSOR SIZE AND USE SHORTER LENSES YOU REDUCE IMAGE RESOLUTION FOR A GIVEN LENS QUALITY.

I'm in need of some longer glass, longer than 300mm. It occured to me the other day that the crop of a given area of a frame would be consirerably bigger the more resolution you have from the sensor of the camera viewed at 100%. So I'm thinking 400mm on the K10D would be approximately 33% bigger at the same crop as it would be from 300mm viewed at 100% right? So if I'm using a K20D how much bigger would a crop of the same subject shot with the K10D be viewed at 100%, could I substitute pixels for focal length providing the lens resolution is up to the job? Are there any downsides other than the obvious differences when using a shorter focal length such as DoF?
