Recently purchase AR7II and have mated it to the Canon 17TS with the Metabones adapter.
Images look excellent.
Now, take the 17TS, add the 1.4 Canon Tele Extender and you have 23.8/24mm TS lens equivalent.
Has anyone done this?
If so, results?
It sure would be a lot cheaper and far less weight in my backpack if it gives excellent results.
