Why I opted against the Sony a7xii (it's all about Metabones)

I drove down to Dunedin today, all set to buy a Sony Alpha a7ii with Metabones adaptor for Canon EF lenses. The camera appeared to be great--excellent size, fit my (relatively small) hands well, nice features, etc etc--and with a Sony E lens attached it focused quickly, and was nice and handy. But when I attached the Metabones IV adaptor (which we discerned had the latest firmware) my EF lenses were extremely slow to focus, almost to the point of being completely unusable. Since my EF lenses are slightly old, we tried some of their brand-new lenses just to see if it made a difference, and if anything it was actually worse. While I was willing to put up with somewhat slower performance than I can get with my Canon 5DmkII, I was not willing to go quite this far, so I ended up leaving with my money still in my pocket.

I think I am now in the position of waiting for Canon to come out with a comparable product, and a way to use my existing lenses. In the meantime, I will bring my Canon body and lenses with me to South America next month, together with my brand-new Sony RX100m3 (which I love so far).
