Sigma has come a long way, years ago, they were considered inferior but with new lens line-up and razor sharp lenses, it has become one of the best lens manufacturers! This is the result of hard work and good management, well done!

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
