I've now had a few days to compare them rigorously, and the Vic SF is evidently the superior binocular. I can see how some might prefer the outstanding contrast and colour rendition of the SFLs - blacks are rendered so deliciously inky and colours so unbelievably neutral. On a bright day they are just superb and it must be said their resolution is every bit as good as the SF. In all, they are an outstanding binocular and they absolutely blow away other binoculars of similar price.
However, the otherwise giant-slaying 8x40 SFL nevertheless loses out to the sublime 8x42 SF's incredibly relaxed and effortless view, a view that is not only noticeably wider but considerably sharper to the edges, producing that extra-large and positively gorgeous sweet spot that so many talk about. Yes the SFL is wide at 140m, but the 148m I get with the SF combined with that massive sweet spot gives the impression of a view that is very much - rather than marginally - wider and more immersive. Roger Vine speaks of a very wide field as something that serves to make the binoculars "go away" when viewing through them and only the SF achieves that out of these two. Don't get me wrong, I find the view through the SFL far from difficult and certainly not tunnel-like, but after getting used to the supreme ease of the view through the SF I now find the SFL's view a tad constrained and a bit tight.
As for the much maligned green cast, I have only noticed it under some rather unusual and infrequently encountered lighting conditions, usually close to dusk and when there is much dust suspended in the air. I must say the pure blue of the sky through the SFL is very attractive, but I'm absolutely fine with the blue-green tint I get through the SF - is actually much easier on the eyes. Which is another area where the SF beats the SFL - it is much better at controlling very bright reflections in the background of the image, and just coping with high brightness generally. It also excels beyond any other binocular I've used in controlling stray light - here it is much better than the SFL rather than slightly better. I can point in the direction of the setting sun and enjoy a view utterly free from rays of stray light, something I thought I'd never get in a binocular. As for the red half-moons some complain about, I've tried my best to find them but they're just not there.
The ergonomics of the SF are also superior not just to the SFL but probably all other binoculars. A couple of days ago I watched patiently hoping for a crake to emerge from reeds and found myself amazed at how long I was able to watch just one spot without either my eyes or arms tiring. One-handed use is also just as good as it is with the lighter SFL. The handling of the Vic SF is just mind-bogglingly good.
I loved the SFLs but I positively adore the Victory SF. Those coated eyepiece lenses are like deep magenta pools and every time I gaze into them I am reminded that I have the very best Zeiss binoculars available. I will enjoy them for a very long time indeed.
