Hi,
A quick up date...I got my Sigma 30MM f/1.4 lens on Monday. My initial impression is that this lens is outstanding
I am really going to enjoy it. So far I have two indoors shot to share.
It is been cloudly and overcast all week so nothing from outdoors yet, but I am going to Old Towne Alexandria, VA tomorrow and shoot some overview landscapes from the Masonic Temple steps...which over looks the entire town.
Here is a duck(s) shot and one of my grandson at Karate class.
1. Ducks: 1/60th, ISO 400, f/4 with onboard flash.
2. Grandson: 1/125th, ISO 1600, f/2.8 <-- I used Noise Ninja to reduce the grainey look.
I will post some landscapes shots tomorrow night as an update to this post
