I want a new lens, but idk nothing! :/ Help

Although a good combination, that is way out of their price range. Either one of those lenses individually would blow their budget.

The 16 plus UWA gives him a cheap route into wide angle (1/3 of the cost of the wide angle zoom although the zoom is far superior in IQ).

His other options are a tricky one. If he wants low light and indoors then he should get the 35mm. If he wants a portrait lens then he should get the 50mm. If he wants more reach then he should get the 55-210. His budget cant stretch to all of these though so he is going to have to make some compromises.

The 55-210 would probably give him the most versitility. And he can save up for some faster lenses later on.

I've excluded the SIGMA lenses due to their lack of stabilisation and his wish to them in low light.

(Assumed its a guy...)
