I went to Samys Camera yesterday and tried out the Sigma 19mm. All the complaints about the Sigma DN lenses seemed blown out of proportion. I found the build quality solid, I did not notice any lens rattle and the startup time wasn't slow at all (all on my E-M5). I found the lens to be very sharp, though exhibiting typical Sigma colors (leaning to the warm, yellow cast). It isn't very bulky and the AF was quite fast. For $150, it's a pretty good deal for a standard lens with good close focus abilities. I tried the Sigma 30mm and didn't like it all that much in comparison. I currently have the 14/2.5 and 25/1.4. I could see using the 19mm as a nice 'tweener lens especially for daytime use. What do you guys think? Would it be too much overlap with my current kit? My other choice would be to get a cheap 14-42 kit zoom for daytime use. Though I'm quite partial to primes with M43 just to eek out maximum sharpness!
