88SAL: Every one of these bloody lenses is designed with the NEX in mind. How about some M43 optimized lenses sigma? We should be able to squeeze a 19mm f2 for a M43 and no bigger than the current offering. These lenses are so aimed towards the NEX it's not funny, not even worth considering compared to the OLY/PANA offerings.
What's the problem? 19mm (38mm) is very useful for shooting indoors or groups shots (3-6 persons). 30mm (60mm) works brilliantly for general outdoor shooting and half body portraits. I don't think they're too big at all and my copies are sharp as hell.
Bold move by Pentax. At least the company dares to try something new, unlike the disgustingly boring Canon and Nikon.
