Searching this forum and the various review sites I still did not find the answer... most of the cheaper/affordable wide angle lenses, like the Tamron 10-24mm seem to be for APS-C sensors only.
My widest lens at the moment is the 24-105 which is my favourite "walk around" that suits me 85% of the time. I don't need a wide angle very often, so I do not want to spend a heap of money on it.
Any ideas for a FF compatible wide angle zoom (10/15 - 30/40mm) with a Canon mount, not too soft at the edges, not too much CA and in PS/ACR manageable distortion at a reasonable price. I know I am asking a lot. But there are so many wise guys and girls on this forum so there should be an answer.
