I compared the angle of view of my SONY HX-50 to my a6000 using my Nikon 300 legacy with Metabones adapter plus Nikon 1.4x extender. I expected the HX-50 (129 mm with advertised "35 mm equivalent" of 720 mm) to give a "longer" lens. 300 x 1.4 x 1.5 = 630. In other words I expected that my pocket SONY would reach out a little better than my legacy "stack" of glass. 630 is much less than 720. To my surprise, the results were clearly the opposite of what I expected. The image on the a6000 was bigger (relative to the frame) and it did not take fine measurements to see it. This is not a trivial difference. Something is not as it looks OR I'm simply not using the numbers correctly. For those who wish to double check my specs, I'm using 6.17 mm x 4.55 mm for the sensor size of the HX-50 and the 129 mm = 720 mm is what SONY says. When I use an online calculator of field of view, I get 3.8 degrees for the a6000 and 3.1 degrees for the HX-50. That agrees with what I was expecting. Are there any experts out there who can clear this up? I can supply test shots later, but for now, assume I am accurately describing my results.
