Short Review – Sigma 50mm f/1.4 EX DC HSM

by Enche Tjin on August 20, 2008

Following the success of Sigma 30mm f/1.4, Sigma launches 50mm f/1.4. It is Sigma premium prime lens ($475 street) The build quality of this lens is very sturdy.


Mounted in Canon Rebel XSi / 450D, the lens body texture is very pleasant to grip. It is heavier than other prime lenses but it is not a big issue. The lens cap from Sigma has a similar built quality like the lens body. Unfortunately the lens front and rear cap are made from cheap plastic and quite flimsy.

The manual focus bar is wide, smooth and anti creep. Overall this lens has an excellent body construction, up to par with pro grade lens.

Due to the big aperture, the lens are wider than other prime lens, this is helpful for people with average to big hand.

Sigma-50mm-standAuto focus operation is fast and quiet due to Hyper Sonic Motor (HSM). But in low light situation such as sunset or dark skin tone, this lens auto focus have problem to lock in the target.

Image Quality
I took several snap shot today to test this lens wide open, the result is impressive. The result is good contrast, and very smooth bokeh or blur due to shallow depth of field. Chromatic Aberration is minimal even in aperture wide open.

What is this lens are for?
Mounted in small sensor camera (Canon Rebels, X0D series, Nikon D40 up to D300, Sony and Pentax digital slr cameras), this lens is equivalent to 80mm (medium telephoto). This focal length and big aperture is ideal for portrait. Other purpose will be low light condition such as indoor sports or art performance.

In Sony or Pentax body, this lens will gain advantage of the image stabilization which gain 1-2 stops than Nikon or Canon cameras.

The lens will come with a lens box to store lens when it is not in use. Extra cushion is provided to absorb shock.

Personal rating:
Image Quality : Excellent 5/5
Build Quality : Excellent 5/5
Price value: 3/5

Travel and general purpose : **
Landscape : **
Portrait/Still Life : ****

nice quick review of the lens. i’ve been dying to get a 50mm lens that will autofocus on my Nikon D40, and this looks like the perfect solution until Nikon actually comes out with one of their own.

Nikon just released Nikon 50mm AF-S f/1.4 and Nikon 35mm f/1.8 DX
