I currently have an E-M10 (and grip) with the kit lens (14-42IIR) and the oly 25mm f1.8. I'm needing something that gives more reach and that offers good low light performance. I plan on using the lens(es) at school plays, theater performances/concerts, swim meets, school field days, travel, etc. I'm wondering what people's thoughts are regarding these two options: 1) oly 75mm f1.8 + oly 40-150 f4.0-5.6 2) upcoming oly 40-150 f2.8 Obviously the 75 will perform much better in poorly lit theaters/school gyms, but I'm limited to a single focal distance and I don't always have control over relocating myself during these activities. Either zoom will give me the reach I need, but the cheaper option will not perform as well in low light and will also limit the use of faster shutter speeds I may need during some outdoor activities. My first thought was that the 40-150 f2.8 would be the perfect lens for me, but I'm concerned about having to pump up the ISO in poorly lit situations. I'm very pleased with how the 25 f1.8 does in these situations so that's why I started thinking about an alternative. I'd love to hear your thoughts!
