After some photos taken recently, the results are very positive: this lens provides excellent performance, is light to carry (especially when you have other goals), all at a very competitive price. Even if you can criticize the lightness of certain materials used (apart from the lenses are of excellent invoice) from the model opening at f 1.4, given the non-intensive use as I do, I find the choice quite adequate. The price difference compared to 1.4 f overrides the decision.
