Well, it depends on what's your genre. If you are a bokeh guy, then go for the 50mm.
Shooting a 18-55mm @55mm @f3.5 might, I say might, give you some bokeh.
If you dun shoot wide for 90% of the time, then go for the 50mm & save up for 18-200mm or go for the 18-200mm kit & save up for the 50mm.The choice is yours
Uncle MM! At 55mm is f5.6 le. :sweat:
