You are correct Aquilan - I thin the combination of the Zeiss and NIkon D800e is without comparison when it comes to this kind of shooting situation - I have found each of the Zeiss lens have their own "personality" and they each take a long time to get accustomed to their strengths and their weakness. The 21 is challenging in wide landscape shots - in this case there is no strong anchoring visual element in the foreground so the eye needs to be satisfied looking at color and form in the rest of the composition - thank you for you kind comments
