I have an E-PL6 with double zoom kit. So, it is really a beginner set. I think about an upgrade. At first only in lenses. A better body may come later. After a lot of searching and reading, I found the following options. At the end I would like to use the smallest system if it is possible. Smallest means: pieces of lenses, weight and of course the price. Option 1: O 17/1.8, O 45/1.8 and the 2 kit zooms Option 2: S 19/30/60 2.8 trinity and the 2 kit zooms Option 3: O 12-40/2.8, the 40-150 kit zoom and later, if necessary, a used S 60/2.8 I have only limited resources for that. I planned to use for a general situations and the most important, images about my little twins. What's your opinion? If I choose option 1 or 2, and later I would/could buy a 12-40/2.8, the spent money for primes wouldn't be the most efficient way in budget, if the primes aren't significantly better. I doubt that. If the primes aren't much better as the 12-40/2.8, I should sell them, but in this case, I will loose money with that. Which is the better, regarding image quality/sharpness/AF-speed/AF-accuracy/bokeh? (Without the effects between the max. aperture).
