Hello:
There was even talk of times recently that a superior UV filter through the so called Glow-effect image quality in the EX3 would mess up - which I do not really make sense really. Now I have the Fujinon Wide AngleXS8X4AS-XB8 increased (dreamy!) And it wants to protect by a UV filter with dirt and scratches.
So the question now is really something to it s.dem talk of quality losses in the Picture?
Thank you!

Each glass is theoretically more quality loss. But synonymous every scratch on the front lens ... So? Of course, you screw a filter on the valuable optics. Pay attention to take a good multi-coated filter with as small text, so that no vignetting occurs.

@ Heinavesi
Wide-angle shots sin always a problem with UV filters, as obliquely incident light reflections and thus to Interferrenzen within the 30-50 (depending on the quality of the filter) dichroic layers.
We have tested such a long time (varying) filter, and really only found a filter that appears to be the problem, replaced by an appropriate dichroic dye) (Tiffen, because when it comes to the dichroic filters, cyan, respectively Piupur vignetting.
This has nothing to do with filter sizes, but with the incident light s.Optikrand. (Our filter was 5.6er, ie large enough to avoid such problems of the beginning).
This coloring you get off properly with a new white balance and is free of vignetting.
But the best protection for the lens is still a careful handling of the camera and with the appropriate lens, not soange You turn in areas with explosion hazard. There is certainly an appropriate protective glass better than a filter that you always have your beam path changed. Synonymous Remember that the camera is already making an appropriate filtering in front of the sensor. So here you kaskadierst filter.
