I recently reached a milestone anniversary with my lovely bride, and she totally shocked me and presented me with a Zeiss Touit trifecta for my Nex-7 - the 12, the 32, and the 50. She must think I'm a worthy husband ;-) But these new lenses present a problem, because now I have overlap with some of my existing lenses and could use some advice on which to keep and which to part ways with. My other lenses include the SEL24F18z, the SEL35F18, the SEL50F18, the SEL1018, the SELP18105G, and the SEL55210. I don't think I can part with any of the gift lenses without creating massive ill-will, so which ones should I let go? I'm thinking the 1018, the 35, and the 50, but some of the reviews I've read suggest the 35 bests the Touit 32. Also, the 24z and 32 are fairly close in focal length, so maybe the 24z needs to go too. I don't concentrate on shooting a particular type of subject (e.g., landscapes) and would prefer to have a set of lenses that can cover nearly all situations. Any thoughts/suggestions appreciated.
