Just before photographing a Sydney wedding a couple of weeks ago, I had the opportunity to do a side by side comparison of my Canon 70-200mm f2.8L IS USM against a Sigma 70-200mm f2.8 II EX DG Macro HSM.
I LOVE my Canon but it’s an expensive piece of kit and costs more than double the Sigma. The Canon has Image Stabilisation, which can be very useful – especially photographing a wedding inside a church but in my opinion that’s not enough alone to make up for the difference. I have always heard good things about the Sigma and I looked at it very closely before buying the Canon. There are some well respected lens review sites which suggest the Sigma should be sharper than the Canon.
So – I was geekily excited to be able to do a head to head review. My excitement was short lived. I really expected them to be close, but it wasn’t.
The images shown here are 100% crops taken from the centre of the image. The green foliage above the purple flower in front was the focal point. It was shot at 1/1250th second zoomed to 200mm and the Image Stabilisation was turned off on the Canon. They were taken less than a minute apart, the lighting conditions did not change and the white balance was set to the same value for post processing of both images.
For a lot of photographers, the extra cost of the Canon 70-200 can’t be justified but I’m very glad there’s often one on the front of my camera.
