As stated by @t3mujin in another thread's comments:
Stacking filters will decrease image quality, as it's another piece of glass light has to go through before reaching the sensor.
I was wondering whether this is true, or better yet, how radical the quality decrease really is?
I was thinking about using UV filter on my lens and on that, stacked a polarizer. This combination of filters sounded to me like a great idea on how to shoot the nature, but after I read the aforementioned, I'm really wondering whether I might be wrong.
What would be the best option for this situation?
