Hi, Has anyone used the Olympus 40-150mm on a Panasonic GF1/2/3? Having given up on the 45-175mm X lens due to poor OIS I am looking for an alternative. The Panasonic 45-200mm is one option which has OIS, but is heavy. The Olympus 40-150mm is half the weight but no OIS. With the GF2, in the short time I had the 45-175mm I noticed the image stabilising was useful for framing and focusing the picture at the long end (but useless if you wanted a sharp picture as it happens). So, I have wondering if anyone has used the combination and finds the lack of image stabilising a problem, or if it is fine provided you keep the shutter speed high? I don't have an EVF, which may help with framing (I am more used to DSLRs) but I don't plan on using an EVF - I am trying to keep size and weight down. Thanks, Keith.
