Hi. Just received the miniature 12-32 lens in black. My other lenses: pana 12-35 f2.8, pana 14-42 pz (soon to be sold) and rokinon 7.5mm fisheye. Over the last 2 years I had and sold: pana 20 f1.7, pana 25 f1.4, oly 45 f1.8, pana 14-45 original kit zoom, oly 12-50 and the oly 14-42 kit zoom. In short - I found the 12-35 f2.8 best suited for my needs and disliked the primes for my style of shooting. If the kit zooms the 14-45 was best and the 14-42 pz a close second. Now to the new 12-32. In anything but extreme upper right corner it is a serious threat to the 12-35 in the same apertures 4-5.6 at 12mm. going to 32mm the difference between the two is very apparent in 100% pixel view all over the frame. Still, the 12-32 resolves better than the 14-42. As to distortions: the 12-35 slightly better. But here's a funny thing I noticed - if the camera is static and I just switch between the 12-32 and 12-35 with both set to 12mm, the 12-32 gets a broader view angle (probably because it is physically shorter). This might seem like nothing but if you ever get to those 'lean all thr way back to the wall to try squeeze it in the frame' you'll see this as a definite advantage. The zoom ring is smooth, having to turn the zoom to open it up for use is annoying, but a lot smoother than the original oly 14-42 was. In my opinion this lens comes closer to the 12-35 in terms of IQ than any other zoom kit lens (and I had quite a few if then and shot a lot of photos with all of them). The size difference compared to the 14-42 pz is small but noticeable (almost as if not mounting a lens at all). I only tested it with the G5 and all 3 (12-35 12-32 & 14-42pz) were compared by shooting on a tripod with 2 second delay and in manual mode. and processed identically in my automatic lightroom workflow. What I miss compared to the 14-42 pz is... the pz (makes shooting videos one handed with the g5 smoothe as I use the lever on the g5 to zoom). Other than that - excellent lens!
