For this shot I used the Canon 16-35 2.8 original version, which I have owned for around 15 years and which when used with various cameras (including the 5D and 5DMkII), I soon became very reluctant to use it, as the CA and colour fringing when coupled with these cameras, was so bad that it kept ruining what would have otherwise been perfectly good shots, however I did use it occasionally for black and white work, as I could more easily hide its inherent problems. Then I bought an A7RII and after a couple of years of not using it on this system either and me occasionally looking at the lens sitting unloved and gathering dust in a corner (I even thought about selling it for not much money), but then one day I did try it out of curiosity and WOW!, the difference is simply amazing and it has now been transformed into a truly stellar lens IMHO. So I don't know if it is the better algorithms in CS6 ACR, or the uncompressed Sony RAW files that helped to all but remove these problems, or whether it is Sony's back illuminated sensor and the shallower photosite technology, or a bit of all three, but either way (and who cares), because this lens is now pretty much amazing and as such I have now totally fallen in love with it, after many, many years of snubbing it and thinking I had wasted my money.
