I've done the round-robin of the existing threads on the subject, but there's nothing recent, and specifically relating to the D800, so I haven't pinned this on the end of an existing subject only for responses to inadvertently be added addressing the original poster once I'd exhumed the thread with this post.
I want a fast and pocket-able wide to ultra-wide prime for my D800 (which arrived at the weekend and I still feel like a 5 year old on Christmas morning).
I've found very mixed reviews about this lens in particular, but on balance, this seems to be the better performer amongst the other lenses around it, taking a very unscientific average of general internet opinion. I'll want to be using it for low light indoor stuff, parties, dances after weddings etc. where I can get right in amongst a tight group of people on dancefloor for example. I will have it cranked close to if not slap bang wide open most of the time I would have thought.
I suppose it may also serve as a landscape lens where size, space and weight is an issue, but that's kind of way out the window anyway with a D800, plus I'm still young(ish). The 16-35mm is very much on the cards for me before new year anyway, so I'm not too worried about covering that aspect or its stopped down performance versus wide open.
So, I'm after some feedback from the good folks of NR on this lens, alternatives that don't cost say upwards of £400/$600-$700 and in particular, any experience of it on the monster sensor inside the D800.
