Sigma 14mm f/1.8 Art - whoa! by Stephen Scott

I decided to continue my love affair with the Sigma Art series of lens and change my Nikon 16-35mm f/4 for the new 14mm f/1.8. This lens really is on a different level to any other ultra wide I have had the pleasure of using. The picture below was taken with the D810 and the Sigma and manually focused at f/1.8 for the stars. Getting sharp focus was a manual focus job but that is to be expected at night. The rewards are great though - yes I could have stopped down to f/2.2 or f/2.8 but it meant I was able to have relatively short (15 second) exposure times and a low ISO of just ISO-640. 

I did make some mistakes with my intervalometer settings so missed a few images but I was happy with how it came out. It was a total of 280 images edited in Adobe Lightroom and exported as layers (TIFF files) into Photoshop. It, on more than one occasion, filled the scratch disk which had 120GB left on it at times during the editing process and certainly tested the computer.

As I was editing the image I decided it might be fun to change the background in another photograph from my collection of Devenish Tower on Lough Erne. The photograph of the island was taken at sunset so the foreground elements needed to be muted - your opinion is more than welcome.

I also decided to try some light trails from a bridge overlooking the main road in our village. I could do with taking these again during rush hour but this was around the 120 frames mark.

 This image was taken of a plane departing Enniskillen/St Angelo Airport into the starry night sky. It was a 30 second exposure at f/9.0 and ISO-800. The lens locked focus almost instantly on the landing light.
