Despite deciding a while back to stop acquiring new photo equipment, I couldn't help but buy the new Tamron telephoto lens - 150-600mm f/5-6.3 Di VC USD G2. I am so glad I did. It is relatively small, light, and affordable for this focal length. Image quality is very good along the whole range. Image stabilization allowed me to handhold the camera at shutter speeds 1/5 the focal length and slower and still get sharp images, especially at longer focal length. AF is pretty good, though I found myself having to use manual focus at times during low light. The minimal focusing distance is about 2 meters, so I was able to get something close to macro images. And bokeh looks good. I'm very happy with this lens and want to share a few photos from one day of shooting at the Fairchild Tropical Botanical Garden in Miami, Florida.
