I am looking at getting a longer Pany lens I am thinking either the 45-175 or 45-150. I have read various posts and know that some people have had a few problems the 45-175. I am leaning more towards the 45-150 many with it being cheaper and from what I can see a bit smaller. I currently use a GF1 but also tempted to get a G5. I know I can get the 45-175 in the UK now but as far as I can find the 45-150 is not out yet and due in October. If anyone has used the 45-150 can the give any option on it? Just want to get a few views on both lenes before splashing the cash!
