Hiya my name is Leanne I'm not new to photography, as I have been into it for a few years now... Got my Pentax K-30 almost a year ago now!! Only got two lenses a pentax 18-55mm and a sigma 70-300mm, which also has macro! But not 1:1.. I'm looking to maybe buy a macro lens in the future as I love talking close ups!! I also love taking portraits' any ideas on what lens would be best for this???
