As I had posted before, I wanted to get the same lens I had with my Canon onto my Sony. Here’s another lens I got for my Sony A65. It’s the Tamron 17-50mm f/2.8. My wife got it for me for Christmas. It’s a great all-around/walk-around lens. I enjoyed it on my Canon XS and now I’m enjoying it on my Sony.
The focusing motor noise is there but it’s not that bad when recording a video. Using the built-in microphone on the A65 will pick it up slightly. If you use a higher mounted mic or external mic, you should be okay.
