Some impressions of the Bol d’Or 2014.
All images have been taken from long distance, using an 800mm Sigma f/5.6, combined with a Sigma 2x Teleconverter and a Sigma 1.4x Teleconverter. Camera Nikon D4 was set to ISO 8000, as the teleconverters moved the f stop to f/11. Quality of the images is not impressive, but I wanted to try how it works with two teleconverters and manual focussing.
