Hi all, I have a question for those users that have used both the 14-54 MKII and/or 12-50. I have to decide which one to buy and have many doubts. The IQ of the 14-54MKII I read somewhere is better than the 12-50. Size is not a problem and I wouldn't use it in situations where lighning fast AF is needed. I know that it seems strange but I would use it instead of the standard 14-42 kit lens with the Olympus adapter that I already have. Can you share your thoughts and experience please?
