Да много, чего имеется.
Вот сравнение 24/1.4 с 14/1.8 и 24 мм на 14-24/2.8 - http://www.dxomark.com/Reviews/Nikon-AF ... 4mm-f-2.8G
А тут сравнение Никкора 24/1.8 с Сигмой 24/1.4 и Самьянгом 24/1.4 - http://www.dxomark.com/Reviews/Nikon-AF ... 24mm-f-1.4
Новый Никкор 24/1.8 всюду резче, и по всему полю. У 24/1.4 есть только одно преимущество - диафрагма 1.4, а не 1.8.

Nikon 24mm f/1.8G conclusion: Superb 24mm option for Nikon
For Nikon shooters after a top-end wide-angle lens for high-quality architecture, landscape, and interior shots, or just to fit a bit more in the frame, there’s everything to like about the new Nikon 24mm f/1.8G. Affordable and outstanding optically, it’s in the top ten for all lenses tested on the D810, as well as being the sharpest 24mm wide-angle tested to date on this camera. Not only that, it boasts better chromatic aberration results and similar other lens metric scores when compared to the 24mm f/1.4 competition from Sigma and Samyang. If you need the f/1.4 maximum aperture for low-light work, the Sigma 24mm f/1.4 is a better value than Nikon's own-brand 24mm f/1.4G option, but both are surpassed optically by the brilliant Nikon 24mm f/1.8G.
Лично мой выбор окончательный - Никкор 24/1.8
