I bought all my Nikon stuff in a very short time, and today I completed my m43 lens kit that I personally need. My final purchase was to buy a used Oly 9-18mm to replace my Nikkor 12-24 DX as my "Normal" lens. My normal lens for video is the 12-35mm, but for walk -a-round stills on either my Gx8 or EP5 this is the perfect lens for my style of shooting. I have quite a few m43 lenses now and can say that I like each and everyone of them. I did a test shoot with the lens today and created a set of parameters in LR/Bridge that seen to make this lens shine for what I need. My travel kit will now be either this lens and the 35-100 f4/5.6 (don't use this focal length much so no need for the 2.8) or 75-300 II, depending on what I am doing. My video stuff will mainly be done with the 7.5/12-35/100-400. While the Sigma 30 and the Pany 14 (w/wo GWC1) is my stealth kit for the EP5. Don't know why but I can't seem to bring myself to sell the two Oly Kit lenses, but they are not seeing much use, but could come in handy for selling a camera like the EP5 on Craigs list. Don't shoot macro like I once did but I have Canon 500D for the longer zooms and PL 100-400 is very good for big insects as is. For me I've found a good mix of glass and can only say that I am very happy with M43 and am very glad I made the change. I'm not of a prime shooter and picked up the 14 & 30 when the EP5 was my point and shoot and I wanted something better than the kit lenses, but I've got good copies of both and for what they sale for used, well they are still great lenses when I want to shoot small on the EP5.
