Hi
Sorry to resurrect such as old thread, but I am experiencing the exact same problems.
Looking at these responses, it would seem that cheap UV filters are doomed to ‘reflect back’ on the Canon XM2/GL2.
There is recommendation to use a ND filter instead, but this requires ‘unfocusing’ the unwanted reflection… and meaning iris and depth of field must be changed to suit the filter.
Before I buy a new filter for my XM2 that will not give me an unacceptable reflection, is there a product that will screw on which will not reflect back but also does not require the reflection to be ‘focused out’ by opening the iris [as an ND filter would]?
My goal is to protect my expensive lens, but still have the freedom to change exposure as normal to suit the film… not the filter.
I note the comments about linear of circular filters. I cannot find a circular ‘UV filter’ as such, but there are plenty of circular ‘polarisers’ available.
Can anyone confirm is screwing on a circular polariser will not produce any reflections, at any exposure settings?
Thank you for any help
