Two Basic Questions
Jun 11, 2013

This may not be the right forum for these two questions, but it is the forum I am familiar with. I have read this forum every day for well over a year. I have come to respect the great technical knowledge among the Sony Alpha community and I am looking for technical answers.

1. I have an OM2 setup with four lenses back from the early 80s. How come my Sony APS-C lenses are bigger? And Full-Frame are even bigger than that? The OM system was full frame and the lenses were nice and small. I find it hard to believe the auto-focus hardware alone makes things that much bigger.

2. I have a circular polarizer now. When I rotate it, I find it hard to see the difference in my EVF. I know about being 90 degrees to the sun. It was extremely easy to see the difference when I turned my linear polarizer on my old Olympus gear.

Thanks
