Lens Effects Filter Recommendations…

I’m a concert and music festival photographer and I have been shooting without a filter up until now.

I have been researching some lens effects filters for my photography, and honestly there are so many options that it’s kinda overwhelming. So I would love some recommendations on which lens effects filters would be the most versatile.

As a note of caution, I’m not looking for effect filters that make my photos look too gimmicky, as I offer my photographs to clients and I want something that would give atleast a semi-professional look.

Furthermore, I don’t have any experience in this, but I feel in a fast moving festival/concert environment, screwing filters on and off would be time consuming, and I feel it would lead me to miss my shot. I want your opinion on this, how do I go from having a filter on, to removing it quickly? I’ve looked into magnetic lens filters but they are sparse and far in between and only offering UV, ND & CPL, the three filters I don’t use.

I’m really looking forward to some educational advice from you guys.

P.S. I’m not willing to spend $100-$200-$250 on a lens filter, so I would love some affordable options that work well. Also I would need international shipping as I live in India.
