Lens produces pleasing results - minor image quality issues
Greybeard, 30/04/2015
My first experience with a wide angle lens! Whilst this lens in comparison to a standard zoom affords additional coverage, there are unfortunately, a couple of negatives.
At its widest angle there is noticeable fringing / chromatic aberration towards the edges of the image which in most cases can be easily corrected in Lightroom. Also, there is some compression of perspective, which is especially noticeable in the foreground and at the corners of the image, i.e., people and objects can appear flattened.
In summary, despite the negatives, this lens produces crisp, clear images with good colour. I’ve tested this lens in various situations including cityscape and landscape locations. I consider this lens is best suited for landscape photography where any apparent compression of perspective is minimised.
Pros:
Easy to use, Build quality
Cons:
Bulky
