Being self-employed, I need value for money but I also want the best equipment. I was first introduced to SIGMA in 2014 and was impressed with the professional specification of the lenses that they were going to launch which included an inclusive 3-year warranty program. I had become increasing frustrated with Canon in terms of spiraling costs, warranty and repair issues. Therefore I decided to trade in all my Canon lenses and replace it with SIGMA equivalents. A bold move some would think but I have not regretted it at all!

Recently I had the pleasure of trying the new SIGMA 70mm F2.8 DG MACRO | Art lens with SIGMA TELE CONVERTER TC-1401 1.4x with my Canon 5DMKiii in the field photographing invertebrates.
