Besides the fact that you need a static to reasonable use of lenses with this focal length, I was somewhat disappointed by the photos more. They seemed all too pale, the saturation was too low. In addition, it takes some practice to set the lens focus manually, Micrometer-work, from 3m to infinity approx.1 / 3 of the filter scope.
Yet I do not regret the purchase, the customer service is vobildlich and accommodating, the price is also not bad when I think about that the same lens with an appropriate T2 adapter for each camera type (in my case so) to 100 Euro more would have been. Which reminds me, who needs a T2 adapter on Fuji X. Can be picked up for free at me !!
