I'm afraid to try out the 24-70/2.8S. Maybe down the road a bit. I picked up my usual three... 35/50/85 and am happy with all of them. I have a bunch of F mount glass and am delighted by how nice these three Z primes look in comparison. My plan is to spend some time with these and then go wider although I have some MF AIS lenses kicking about if I need something in the interim.
