I wanted to get the Canon 16-35mm f/4L or the Tamron 15-30mm f/2.8 lens adapted for A7ii. Well over almost one year's wait, I picked up a $230 excellent condition Sigma 15-30mm lens. Photozone has a review here: Sigma AF 15-30mm f/3.5-4.5 EX DG - Review / Lab Test Report It's heavy, bulky and noisy when focusing. But IQ is pretty good and when mounted on MC-11 or MB4 with a7ii, the AF is fast and accurate. Can't believe it is such an old lens! If you are on the same boat wondering to get a 16-35mm lens, this Sigma lens might be another option. I didn't have chance to do some landscapes, here are just a few in the city.
