William Anderson wrote:Hans, a quick question. You stated above "I am not sure where fixed lens vs. interchangable lens influences the focal length." I shoot, both on my compact camera and my DSLR in aperture priority mode. If the equations that determine the depth of field for both types of cameras result to little difference, this is a non issue, but, my purpose for raising the topic to begin with was that in many of the early photographs I discussed the f/stop used resulting in various depths of field. I wanted to clarify any confusion if others were looking at those numbers and expecting similar results. I didn't want to be posting misleading information. When I post comparative images with stated f/stops, I thought that information would be useful, but if conversions are necessary for each individual camera, those stated f/stops are of little value to the reader, other than to describe results with higher or lower f/stops or aperture settings.
As the sensor size in the respective cameras is hugely different in size, and also the focal lengths, the aperture used is very relevant - as is providing such info as to allow different images shot with this mix of cameras to be compared.

Bumping topic, since there was a recent question about photography.

Ray, there are some interesting comments in this thread as well as quite a lot of work, but man did this thread ever go on and off the rails. It’s useful in a crime scene forensics kind of way. There’s good stuff here, but you’re going to have to gather some evidence and attribute motives and then start ruling out suspects.
