I am expecting my 16-35 to ship with my 5d3 soon... I never used a 16-35 and i am buying it for my honeymoon in italy...
My question is, is it a good idea to use the 16-35 to shoot my wife-to-be and myself to have a good landscape scene in the background or shall i stick with the 24-105 for people shots and use the 16-35 only for landscapes?
Any people shots are welcome especially @16mm.
The ultra wide angle lens is never good for portrait work. If you include people in your shoot, it either be too small or far. If you bring them closer as your main subject, you will distort them in some ways you won't like. You will definitely have problem balancing the subject and the background. It will force you to compose your shot critically and this will 'slow' you down. I don't think your bride will have patience standing still while you are composing the shoot.
Since you are on a honeymoon, you would be better off with your 24 - 105 lens
