At the point of upgrading to my 1st FF from a T4i. I mainly shoot Long exposure in Landscape / Cityscape and Architecture.
Have done a bit of research and have narrowed it down to the following 2 options.
Canon 16-35 2.8 ii (+ Can take a filter, weather sealed. - Not the sharpest, Expensive).
Canon 24 -105 ( + Range, Cheap, IS. - f4).
Tokina 16-28mm f2.8 ( + Sharp, Cheap. - No Filter without an expensive adapter).
Tamron 24-70 f/2.8 ( + Sharp, Cheap, 2.8. - ?).
I will be bringing over a Tamron SP 70 - 300 from my crop.
Any thoughts or recommendations appreciated (Budget is just over £3k including the 6d).
