Be aware that the 35 f2 IS has strong coma abberations, which is not always mentioned/tested in reviews.. It's pretty much the only downside with the lens.. It's especially bad with streetlights and stars, but also text (signs etc), shiny things and other sharp contrasts... In some cases the background can get quite messy as well, but not always. It really depends on the kind of pictures you want to take with it, if you'll notice it and find it problematic or not, and as with many other abberations, it gets stronger out towards the edges, so it might not be noticeable at all on a crop, and then give you a surprise when you switch to FF in two years
