Pros: Build, lens hood + case included

Cons: Bulky, heavy

Opinion: I have been interested in the focal length and there was a dealer who had it on sale for 299,- EUR. Nevertheless I watched some videos on YouTube. The lens is optical corrected against some flaws, but it is not perfect. There is a great difference between f1.4 and f2. I will never use f1.4. I'm not sure what happened, but I have had unsual high number of pics being not sharp. The sharp ones I have posted here. I think the lens performs well. I was surpised how well the lens renders the background at f4. Overall it's a nice lens. The two drawback are the weight and the weak performance at f1.4. So when you do not need the f2, a good zoom lens gives you the same. The lens is perfect for me, because I enjoy to have a photo walk with only one or two focal length in the bag. I'm also interested in the Irix 30mm f/1.4 which performs better then this one.
