Below is a picture of my Canon EF 28-135mm IS USM f/4.5-5.6 big heavy glass lens perfectly mounted on the adapter to the Sony Alpha 7.
I was able to achieve auto focus on this lens, though as expected, the AF via an adapter [click here] is slower than with a native Canon DSLR lens.
Below is a picture of the expert shield screen protector l got for the Sony Alpha 7 from Amazon.
It fits easily, is cut to the exact lcd shape and works very well.
