Sigma 12-24mm on Canon EOS 5DSr Test!


The Canon EOS 5DSr is a beast. Not just because it’s a highly professional, full frame, versatile and complete camera.

It also features a Low Pass Filter (LPF) Cancellation filter. When you have any other digital (SLR) camera, there’s a Low Pass Filter in front of your sensor. This causes a nice piece of anti-aliasing which effectively blurs your image slightly, to prevent moire. (Read more about it) This is very noticeable when you shoot area’s with small patterns such as the texture of clothes. However, to get maximum sharpness, the 5DSr has another filter cancelling this effect out.

Another reason the 5DSr is a true beast is it’s sensor. Canon must have thought “Ah more sharpness, let’s capture that in all of it’s glory”. So they came with a 50.6MP sensor. But with all this sharpness and all these megapixels, will your favorite lenses hold up?

I wanted to have a super wide angle lens without the fisheye effect. I love the Sigma 15mm fisheye, but a regular wide-angle does have it’s benefits. The new Canon 11-24mm f/4l looks superb, but so is it’s price-tag. So I went for the Sigma 12-24mm. Well, this isn’t going to be a review, but I have to say I’m very pleased with the results. IMHO, they’re easily ready for large scale print. Enjoy!
