I have a Bronica ETRSi with an AEIII metered prism.
Can I use a linear polarizer, or do I need the circular?
I've gone crazy searching this but haven't been able to
figure this out.
I know that linear is ok for manual focus, but certain types
of metered prisms (split beam?) require circular.
I cannot find any info on the AE-III prism and I have contacted
Tamron without any results.
I'm only talking a matter of 30 dollars between the 2, but......
Any input would be greatly appreciated
