Dave regarding the A119 do you think buying the CPL when it is released a good idea, will it really cut down the glare What percentage of reduction would it approx. cut down?
My experience with the 2 very low cost lenses I tried was about 75% reduction in glare. My dash is real bad. I've been tempted to get a black dash cover for it. If I don't use polarized sun glasses when driving the reflections and glare drives me nuts.
I was just thinking... my son is an Optometrist. His optician shop cuts down lenses every day. Why don't I buy a glass PL or CPL camera filter for a few quid and have him cut it to size? Hey, I wonder if he can cut to a 17mm x 16mm rectangle with rounded corners!
I think PL would be better as a CPL may delaminate when the edge is being cut (ground) away.
I'll ask him tonight...
Keep in mind that just a few degrees off and the effectiveness of the CPL lens drops quite a bit. If you cut it rectangular, you have to be sure you got it lined up 100% correct the first time. With a round lens you can easily rotate it to get it set to the optimal position.
