okies i am newbie to this
i know that the use of step up/down rings bound to have some disdvantages.
for example, if i am using a 72mm filter to step up to 77mm ...
what actually happens to that 5mm that is not covered?
also for example, if i am using a 77mm to step down to 72mm...
does that means that 5mm got 'cut off'?
ok this might sounds silly to some
so if i really had to use a step up/down ring, so i use a step up or step down is better?
cos currently... i got 2 lens that is 72mm and 1 that is 77mm... so trying to save some cost to buy 2 different filters for all 3 lens.
i know another alternative is to buy those square filters... but i still prefer using the usual screw mount filter.
