    Inspired by the polarizer comments in another thread. Am I right to assume the issues with linear polarizers on modern slr's (metering and autofocus) does not apply to our Sony's? I played around a bit with my old one in 52mm but couldn't test AF since i used my nikors and I didn't make a 90 degree test to see if the metering would go wrong but the 30-45 degree i did turn it during my fooling around didn't seem to make any difference.

    As said when we were going off-topic in another thread, I think you're right. Circular polarizers are needed when there are other optical elements in the light path that polarize in some way or another, like semi-transparant mirros can do; this is relevant for both viewing and capturing. In mirrorless cameras there's nothing between the lens' rear element and the sensor and so linear polarizers work perfectly. I have used old Nikon linear polarizers on my Panasonic G1 with perfect results.

    Linear polarizers are old hat, you can't even buy them new I guess, and they tend to be cheap so if you come across a good deal for a clean filter, go for it!

    Well Lee still offer linear polarizers though they also are at a premium price.
