I just purchased my very first ever legacy lens, an Olympus 3.5 135mm. Probably not the best one out there but it was cheap and very clean, and quite small which matters to me (balances quite well on the X-E1). I decided to go for a cheap one just to see how I get on with the manual focussing before I spend more money on better versions. Did not yet have a chance to try it out but I am planning to give it a go on the weekend, so hope to be able to post some pics later.
