As a relative newcomer to photography I have concentrated on wildlife using a G10 and the Pan 300mm ,some good results some not so good. Recently I have been trying to get some half decent portrait shots of the grandchildren using the kit 42mm lens.The question I have is would I benefit image quality wise if I purchased the Oly 45mm f1.8. Below are a couple of my recent attempts. The background is a bit busy but it was a grab shot on Christmas Day. Against a plain backdrop. Many thanks.
