My kids' Taekwondo studio is doing their annual show next weekend. The show is held in the basketball gym of a local community college and is well lit. In past years, I have had a decent keeper rate with older Nikons (D40/D90) and regular zooms. The action was usually too far for my 35mm and 50mm primes. Most of my keepers are between 100-150mm on the APS-C, so between 75-100mm for mFT. I no longer have the D90 and figured that my 5-month old E-M10 should do much better than the D40 (and give me room to crop if I shoot with a faster prime). The kids have gotten better and faster, so I should have the opportunity to get some great action shots. My questions: What settings would you recommend for focus and burst mode? Should I use my 40-150R to fill the frame or would I do better with the 45/1.8? I also have the 75-300 II which would give me more reach if I desire but seems to be a little slower to focus than the 40-150 R.The 40-150 Pro or the 75/1.8 would of course be ideal, but are not going to happen in the next few days Any tips would be appreciated. I will be able to go to one of their regular classes this week and test the camera settings, but it will be in the regular studio, so anything longer than 25mm will be too long. Thanks in advance.
