I recently spend the weekend near Almograve, a very nice beach located in the Alentejo coast. This is an area that I know very well, and for many years now, as you can ascertain from the several posts I have made until now. During this last stay, I took the opportunity to use a recent wide angle lens for the Sony ILCE system: the Tokina Firin 20mm f2.
Tokina are introducing this new lens line for the system, and the 20mm lens is the first one. After using the Zeiss Loxia 21 f2.8 for a while, I was curious to see how this new contender would fare. In short, the new lens is very good, both in terms of optical quality, and in terms of usability in the field. Mind you, it is only manual focus, but for my intended use (landscapes) I see no problem with that.
Compared to its natural competitor, the Loxia 21, the lens is bigger and heavier, since it is one stop faster; it is also not fully metal build, but that does not mean it feels flimsy or not well constructed (far from that). One can feel the heft of the lens, no doubt the result of some nice glass inside, and robust materials outside. In terms of usability, the only nit I have is the lens’ aperture ring turns a bit too easy for my liking; in this regard, the Loxia has more firm detents.
Other than that, the lens shows very well controlled geometrical distortion (I have not had to resort to correction during image processing), good colours and sharpness across the frame, and of course some vignetting wide open (as expected). Even against the light, the lens performed very well, with no detrimental effect on the contrast or appearance of spurious reflections.
Below are some images shot during sunrise and sunset times, along the coast; some were taken using the long exposure provided by a neutral density filter. Personally, I highly recommend this lens to anyone looking for a wide-angle landscape lens; it also allows to save a significant amount of money compared to the price of a Zeiss Loxia lens, which may be important.
