If you are good at something, never do it for free.
If you enjoy something, never do it for money.
this is a lesson learn from most hobbyist turn professional.
investing or not on lens or accessories is a personal answer.
if a person like aquarium, is it worth to buy bigger tank or aqua super clear glass, adding more plants, add co2 system for plants?, using latest tech filter, expensive lights, import soil from japan, freezer to keep the water cool on hot day? best fish food to run a aquarium? this is give the same answer up to a very personal opinion.
i am a photographer(hobbyist, workshop trainer), a gamer(with a 10k rig, multi(4) monitor setup) who keeps a expensive aquarium of shrimps(co2 system is over 2k setup), who also play archery(hobby, several gold medals), and also rides a sportbike(weekend rider hobby, tyre cost few K liao...).... is it worth it? yea, no GF bah....
