各位ching, sigma 50.4 是否應該配上一片較高質素的filter呢?

Why don't you try to take the same picture with (1) a cheap filter and (2) an expensive filter, and tell us the difference.

The difference maybe just the price.

If pointed to a light source, e.g. Sun, there will be a very very big difference among (1) without filter (2) with MC expensive filter (3) non-coated filter
Amount of flare (3) > (2) > (1)

If daily shooting, really no difference

PS, I don't use filters on cheap cheap lenses below $4000, why waste $?
e.g. a EF50/1.8 is $630, a 52mm multicoated filter costs over $100

要高質數就應該唔好用 filter 啦...
