The Nikon 50mm f1.8G is the latest Nikon standard 50mm lens and is available at a very affordable price..
It is a compact and lightweight lens with a deeply recessed front element, and is fitted with a rear rubber gasket to help keep moisture and dust out of the lens mount area.
Weighing only 185g and only 72mm long by 52.5mm wide it is no burden to add to your bag, with
The 50mm f/1.8G is supplied complete with front and rear caps, lens hood and pouch.
Performance is excellent right from f/1.8 and provides a pleasing bokeh effect when used on full frame or DX format cameras.
For full frame cameras, the 50mm focal length is the classic focal length used by famous photographers and so deserves a place in your bag too.
For indoor shots, low light work and portraits it is an excellent choice as long as you don’t get too close.
On DX format it is effectively a 75mm lens and so absolutely ideal for portrait use – nice to get a sharp subject without distortion and a nicely blurred background without getting too close to your subject.
Performance is generally very good, the resolution is very good used wide open and steadily increases as the lens is stopped down. That said, the lens is certainly fully usable wide open and as that is where much of the time you will want to use it that's a good thing!
So, what’s not to like?
The f/1.8 maximum aperture is about 2/3 stop slower than the Nikon 50mm f/1.4G but performance is certainly better with the 50mm f/1.8G at f/1.8 compared to the 50mm f/1.4G at f/1.4.
The f/1.4G will allow a higher shutter speed in low light and is slightly heavier and slower to focus. Stopped down to f/1.8 performance is near identical to the f/1.8G so really only go for the f/1.4G if you need f/1.4 and can afford about double the price.
