Difficult to get accustomed to the menus but taking that into account the performance and accuracy is very good. The menus are confusing but I'm sure once familiar with the menus that problem will disappear.
Not been able to test it to it's abilities as yet , but so far has been very good good. I'm using vintage lenses for the moment which means I can't take full advantage at the moment, I'm sure that will change once I have an appropriate lens setup.
