A bit of a dilemma.
I’ve had a Tokina 12-24mm f/4 for a couple of months now, and so far I’ve been quite disappointed with the softness of images from it. It might be a case of being spoilt by the sharpness of the mighty 70-200VR. Don’t know.
I could replace it with a Nikkor 17-35mm f/2.8, except:
a) it’s bl00dy expensive (3x the cost of the Tokina 12-24)
b) not sure if 17mm is wide enough
c) it doesn’t quite replace my 18-70mm as well, which goes back to problem a) – it’s expensive.
There is also the Nikkor 12-24mm f/4 to consider, which is twice as expensive as the Tokina and some say not a huge difference. Then there’s the Nikkor 17-55mm f/2.8, which could potentially replace both the 12-24 AND the 18-70mm (reducing my “cost” as such). Again, not sure if 17mm is wide enough, and there have been reports that it’s not as sharp as the 17-35mm for shots with far-distance objects (e.g. a landscape).
OR… maybe I’m just doing something wrong. Will keep shooting and trying.
