Q/150-500 Sigma: Moon
I wish it were a little sharper, but it will do I guess. I'm not sure if I am getting optimal focus though. Perhaps a focusing aid?
This is at around 400mm wide open, slightly sharpened. Stopping down only got softer. I put a Tamron 1.4x on my Sigma 70-200/2.8 and then a Sigma 2x and they were all softer than the 150-500. Again perhaps my focusing technique. Using a carbon-fiber tripod with gimbal head and wireless remote, so fairly stable platform.
