So i got this Fuji s9600 and though it has a fixed lens theres a bunch of stuff i can stick to the end of it. i dont know anything about lenses and such, and im wondering about these things i found for macro shots. my main reason for wanting macro stuff is mostly my plants, some of wich are of the carnivorous persuasion and i have never been able to properly capture the rich detail of my drosera. so i find these things on ebay: +10 close up macro lens Raynox DCR-250 Makro Macro close up lenses +1, +2, +4 & +10 Extention tubes (theres one of 19mm and one of 35mm) what does + mean exactly? on wich of these could i use the extention tubes? and wich would you reccomend? in general what kind of quality should i look for compared to the lens on my cam?
