I've recently bought a Sony A7Rii, and have a plasticky 28-70 zoom for general gadding about, a Zeiss Batis 25mm F2 for dancing groups, and will no doubt succumb to the Zeiss Batis 85/1.8 at some point.
However, there is not a huge choice of native full frame Sony E mount lenses out there, and as it seems that with a Metabones or other adaptor, the lens world is my oyster, and Canon lenses in particular, just work, autofocus and all, on the Sony, that maybe secondhand Canon lenses may fill some of the gaps in my arsenal.
I'd like (not really NEED, but would like), and ultrawide, equivalent to the Sigma 10-20 I had for my APS-C Sony A77, so something like 15-30 or maybe even wider? I'd also like something reasonably large of aperture, but not hugely expensive and hugely huge, that is around the 70-200 range.
As I'm not at all familiar with Canon's offerings (apart from a bit of letching at the 85/1.2) I'd appreciate the views of any users here, as to what to avoid, and what to go for.
For the ultrawide, I don't think autofocus is remotely important, and I'm not looking for distortion-free perfection, I've got the Batis 25 for that! I just want seriously wide, for big landscapes or silly stuff.
Any idea of stuff that could be available secondhand, that might serve?
I do already have a Sigma 150-500 zoom, which works with the Sony A to FE mount adaptor.
