What would be the best lens for landscapes on a nikon d800 for around the £300 mark
A used 18-35mm G lens would be my recommendation (not the older D lens). Great sharpness, very useful range for landscape and nice lightweight lens but still feeling good quality. Cheaper, lighter and just as sharp alternative to the 16-35mm f4.
It depends on how you view the lens. It's not rubbish, but it's probably not up to the level people were expecting for a lens of this mark/price. Plus on higher end bodies such as the D810 and D750 it's actually 2-4 marks less sharp than the 18-35mm according to DxO. Distortion is quite bad at 16mm but of course things like this are quite easily corrected in lightroom etc. I personally don't think £300 over the 18-35mm is 'too much' of a premium for the better coating, constant F4 and weather sealing if these things are important to you, but I didn't need the weather sealing or constant f4 so decided to save myself £300, plus I've gained a smidge of sharpness. The coating would have been nice thoughI've heard recently the 16-35 f4 was rubbish wide angle ! That was my next purchase but I'm not so sure now.....
