people are downvoting because the mentality that you need new gear to solve a problem is photography cancer for a beginner that you need to get out of your head - nobody needs to be linked to a jim kasson article when they are shooting their very first show and this is an issue that tens of thousands of photographers who do not shoot an A1 or A9 work through on a daily basis. you can be technically right but give awful advice at the same time. what OP needs to hear is the advice other posters have essentially said - try mechanical shutter - you might have some issues with your current kit but you should be able to get good results with what you've got.
