Long live the 70D! – Not long ago, believing I was fighting with a damaged Canon 50mm f1.4 lens (which is notoriously fragile), I started shopping for a replacement. I considered picking up a Canon 35mm f2 IS USM at first, but after the frustration of a botched shoot caused by failed focus on the 50mm, and stellar performance from Sigma’s rock solid 18-300mm lens, I decided to give Sigma’s Art glass a go and ordered a Sigma 18-35mm f1.8 Art. I’d only just finished calibrating the new Sigma to my trusty 70D when I noticed a dark shadow cropping up in the bottom half of the frame… After a few “WTF?” moments, and a few lensless exposures later, the 70D produced this tell-tale image… That was while pointed at an entirely white screen. I may or may not have been fighting with a damaged Canon 50mm earlier, but I definitely have a dead shutter in the 70D now. In all fairness, it’s hard to fault Canon as I do have around 100,000 actuations on the shutter…and they were not easy miles. The final verdict on the 50mm’s fate will have to wait until my camera is repaired or replaced, but either way, I’m keeping the new Sigma. This last photo is the last photo that my 70D successfully took, and really showcases one of the Sigma’s seldom mentioned talents: macro photography. Web-resolutions really don’t do it justice—those are scratches in the switch, not blur. If you’re considering the Sigma 18-35mm f1.8 Art, and are curious just how sharp it really is, click here for the full-resolution copy of the above image and start counting the grains of dust… I picked up the Sigma as a reliable replacement to the 50mm for portraiture, thinking I’d be able to do landscapes as well since it zooms out to the 18mm mark—one less lens change is one less chance for dirt to enter the camera in the field. I had no idea the minimum focus distance was so low, or that it would be so incredibly sharp. For reference, I’m almost touching the base of that lamp with the front of the lens, and the switch is only a fourth of an inch wide. I can’t wait to get this lens on a new body and see what it can do.… The 70D is Dead
