hi again everyone, just a quicky. im trying to use my tamron 70-300mm lens to achieve some macro shots, but am finding it hard to focus properly, i know it only switches to macro once past 180mm, but my questions are 1, how close can i get to the subject with this lens ?. and secondly this may sound daft but do i need to set the camera to macro mode aswell or does the lens do this ? im using a sony A300. i know ive not got the best kit as of yet before you all say get a better camera or lens lol but its all i can afford at the moment. many thanks. lots of advice welcomed
