Hello all, take it easy on me here! I have been into 35mm on and off for 30 years. I got a new Cannon 35mm but it does not have what I want for Landscapes. I am going to try 4x5 LF and am doing ok with the camera body purchase but now the lens.
Some general boring questions that I can not find the answers to after a couple of weeks.
1. Calculated diagonal for a 4"x5" format is 162.6 mm^2 and the published is 156 mm^2,why the difference?
2. In 35mm world a 24mm Canon lens has a view of 65 Degrees but when I look at the equivalent 90mm lens (Schnider 75mm f/5.6) it has a published view of 105 degrees which is a heck of a lot more than 65 degrees.
3. The formentioned Schnider lens has a image circle of 198mm and since the diagonal of 4x5 is 156mm, don't I lose some of my real world field of view? Like 28 percent!
Thanks in advance, I searched for the info but could not find it
