Owner reviews: Sigma AF 18-50 mm f/ 2.8-4.5 DC OS HSM

NerveNet 26.06.2017 01:09:14
Period of use: 1 year

Strengths:

Half stop wider than Canon's kit lens.

HSM silent and fast motor.

Optical stabilisation.

Affordable.


Weaknesses:

Mine showed a yellow cast in some prictures in certain situations.


Comments:

I used this lens as a natural upgrade from my Sigma 18-50mm f/3.5-5.6 DC lens.

I gained half a stop, it is also a sharper lens than the previous Sigma I mention.

Then, in some pictures a yellow cast in colors could be seen in indoor pictures. I did some other test and finally sold the lens and moved to another lens.

This lens is very affordable.
