Hello, I am looking to buy my first lens for my first m4/3 camera GH3. I will mainly use it for video, interviews/indoor (mostly with light equip.) and some outdoors. I also like general still photography. As it's my first, I don't want to buy expensive. I was thinking of the 14-45, 14-42, (is there really big difference?) or (more pricey) 14-140. If I got good deal I might also purchase a prime such as 20mm (hard to find good deals) or legacy prime such as zuiko 50mm/f1.4 (cheap finds on ebay). Any advice on my choices and where to find good deals would be much appreciated. Thanks.
