I have a Sony a6000 that I have had now for a year. I wanted to buy my first lens since it only came with the kit lens. After some research I settled on the Sony 35mm f1.8 Prime Fixed lens. I took it out this past weekend to a butterfly house thinking I would get some great shots of the butterfly close-up as well as some good portraits of my grandchildren. I did get some good shots but many of my shots were out of focus, more than usual. I was using auto-focus with WB set on daylight since light was coming in through the glass, ISO 100. My exposure was off-I had my aperture set low to blur the background so in some I know that the shutter was not set properly. My question is, are there things I need to do to get better use from this lens? I was a bit disappointed in the results.
