I’ve owned the canon600d for about 3 years now. I still only have the kit lens because I didn’t think I was ready to buy a new one and I have always been unsure of what lens I should invest in. 
 I think now I’m ready to spend money on a lens but I’m not sure witch one to get.
I take all kinds of photos but I like shooting portraits the most. I’m not an expert so I was hoping some professionals could give me advice. 
 I guess I will need a lens with wide maximum aperture maybe f/1.8 max that gives me beautiful bokeh. Although a lens costs a lot so I was wondering if I could buy more of a ,,multi task” lens. 
 Since I live in Iceland there is beautiful landscape and nature wonders all around me so a specific portrait lens is maybe not enough. 
 So I’m looking for a lens with high aperture for taking portraits, a bright lens that can take photos in low light so I can use lower iso, a lens that I can still shoot landscape photos with and a lens that I can zoom even just a little bit if I’m taking family photos. 
 Does this lens even exist?
Is there a portrait lens that I can use for shooting other things fx. photos of the northen lights?
I’m basically looking for a General Purpose Lens but still focusing mainly on portrait photography. 
I’m so sorry if my English is not good but I hope you understand me.
