I have been having a hard time deciding what lends to get for a quite a white. I currently have 5Dc 16-35L 24-70L and 70-200 F4 IS L. I have never owned any prime lenses and I am very interested in 35L 50L 135L. My budget is about $2000 so I can buy any of those lenses but I have thought about upgrading my body as well. Although my 5D is in great condition and I really enjoy shooting full frame. I understand that 35L, 50L and 135L are different lenses and often used in different occasions. I shoot a lot of city landscapes and darker indoor environment. All the research I have done I have never hear bad things about 135L. I understand this lens is ideal for portrait but I am not a professional and I do not shoot portrait often. For 50L i hear good and bad things about this lens. I am very interested in 35L and I hear also mix thing about this lens as well. Also I understand this lends is very old and I guess replacement is coming soon? I know that technology is always keep progressing but I was not sure if I should wait for new one for this lens. I really could use people's opinion and I also love to hear if you use any of those lenses please let me know what do you like to shoot the best for using those lenses. I know this is such an amateur question but I really appreciate your help. Thank you very much!
