Description

This is the first image with my new Sigma 40mm 1.4 lens that I picked up over the summer. Its a hefty thing but probably the sharpest lens I've ever owned, superb for landscapes and easily out resolves my 42mp a7r3. It does very well with coma too - this is taken at f/2. There is some coma in the corners - this is full frame with no crop - but focusing a 6d accurately in live view is not the easiest so it might be a little off perfect focus.
