Without having seen the prints first hand, I really can't comment... Simple arithmetic. The Canon D30 sensor is 2160 x 1440. You said the output was 24" x 36". That means the printout, without any interpolation (except what is done in the camera to make up for the fact that it takes four sensors to get one pixels worth of color information) was 60 PIXELS PER INCH. I have used a Canon D30. It is a very good tool for the right job, but that job has limitations. Looking at an image on a TV screen is hardly indicative of a cameras performance! Do you have ANY clue what the resolution is of a TV? This is a Leica group for God's sake. If you thought that a ZOOM lense on a Canon gives you good enough results, then you probably don't really appreciate your Leica. What you were probably looking at was an image that had something like Genuine Fractals run on it, and had very sharp edge detail, but NO texture detail. If you don't know enough to look for that, you can believe that the image is actually much better than it really is. - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
