I agree with all of you. I agree because it is the way that you want to do photography. I am somewhat in the middle, I love zooms but still have a few primes with my Olympus gear. I have the marvelous 40-150mm 2.8 Pro which my wife and I use for sports and she uses in her studio for portraits along with her full compliment of Nikon cameras and glass. I also have the lightweight but still good Lumix 25mm 1.7, a Sigma 60mm 2.8, a kit 40-150mm, and a 12-40mm 2.8 Pro on the way to me. I had the 14-42mm kit lens but it bit the dust. All of the lenses I have get used by us. I like the 25mm 1.7 for low light and under the basket basketball photos. I used it a lot on our recent trip to Ireland. The kit 40-150 is not the sharpest but it is still a great travel lens and I used it a lot in Ireland as was the 14-42mm. I suspect the 12-40 will wind up on my wife's camera a lot. We still own Nikon gear (D2x, D750, D800) and have lenses from 12mm to 300mm 2.8 with lots in between and each and every one, including the primes (50mm 1.8, 180mm 3,5 Macro, 24-85mm 2.8/4, 85mm 1.8, 300mm f4, 300mm 2.8, 70-200mm 2.8 VR, 28-75mm Tamron 2.8, 12-24mm Sigma, plus older ones) has a place for me to use. My goal is to sell the Nikon gear and get comparable M43 lenses to lower the weight on my recently broken wrist.
