Similar photos/diagrams have been available on the net for years...and yet the confusion remains. I do hope it helps...but someone people just seem to want to be confused.Muy bueno Sparky! I really hope this helps clear up all the confusion that the forums have been seeing as of late
Nice, clear diagram, but the captions are a little confusing. What you are showing as the 'field of view' should be the 'image circle' shouldn't it?
The field of view is defined by a combination of the format and the lens, it is not defined solely by the lens (ie the fields of view are the rectangles - they would only be the circles if the lens' image circle was smaller than the format, which is not the case here).
The image circle is a property of the lens and only the lens.
lol, I understand, it was a joke with all that chat with Helen,, Thank You much
