I just bought a used e-m5 and it should be arriving in a few days. I have been using an xz-1 but I used to shoot with a 40d. I sold the 40d due to the weight and didn't want to carry it around. I was really impressed by the e-m5 and the pictures taken with the various primes. My main interest is taking pictures of my 11 month year old son and wife, whether at home or out and about. When I had the 40d I first used the 18-55 kit lens and later a tamron 17-50. I shot 28% of my pictures at 17mm or 18mm, 11% from 28-33mm, and 37% from 50mm or 55mm. I was interested in the 25mm f1.4 but looking at my use I think I would be better served by the 14mm f2.5 and the 45mm f1.8. Later I plan on adding a telephoto, and maybe an ultra wide or get the ultra wide converter for the 14mm. So does anyone have any reasons I shouldn't do this? Or does it sound like solid thinking? Thank you in advance for your advice.
