Apart from investing A LOT more money in to a new lens, how can I improve my indoor, low light sports photography, particularly roller derby. I currently use a Sony a6000 with an E-mount 50mm f1.8 lens.
Due to the lack of a zoom I often have to crop photos to frame them correctly and most, if not all, require a lot of post processing on the white balance and exposure, meaning I'm left with a lack of clarity and a lot of noise.
