Thirdly, the focus range is not a good "Always top". The 28 mm are to my mind too little wide angle, the 75 short telephoto (all right, the lens also does not rise so claims to be a Tele). I have found myself in the past 2 years repeatedly in how I have indeed often taken the Objetkiv on Tripps or trips, but then finally again used the kit, which is more practical in my eyes.
One more thing: The lack of stabilizer, if you're just spoiled stabilizer is hard to get over, especially because the lens is a lot heavier than just the kit and therefore must be kept quiet. Some photographers, this seems indeed to please if lenses are heavy in the hand, I personally do not - but is determined taste.
I would not say that this lens is bad, no. It has its advantages, and I also have quite a few usable images thus shot (especially in the macro- and Porträtberreich - because that the objective is to use real and the kit definitely superior).
Conclusion: Again, I would not buy it, for me, the price / performance ratio is personally too low. Rather I would be set for a fixed focal length. Currently I use it even for the areas of application described above, otherwise it gathering dust in the closet unfortunately. Maybe I sell it sometime next? I'm concerned, I can not recommend it unfortunately.
