See test images shot with Canon's new ultra wide-angle lens
We've been putting Canon's new ultra wide angle 8-15mm Fisheye zoom lens to the test. While we get on with the review, we thought we'd share some of the images that we've captured with the new lens, as well as share some initial comments on its performance.
The Canon 8-15mm f/4L Fisheye lens was announced back in August 2010 as the world's first fisheye zoom lens offering both circular and full frame images. Release of the lens was delayed because of the earthquake in Japan earlier in the year, but is now available for around £600 (street price).
Here are some of the first pictures we have shot with the lens, along with some initial thoughts on performance.
The lens allows you to focus extremely closely to your subject. In this image, we were only shooting with the front element only just over an inch from the sunflower. This image was shot on a full frame Canon EOS 5D Mark II, with the lens at 8mm.
Because the lens offers such a wide field of view, it's easy to accidentally include yourself in the shot. In this image, you can see reviewer Jeff Morgan's elbow and feet. This image was shot on a full frame Canon EOS 5D Mark II, with the lens at 8mm.
This image was shot using a Canon EOS 5D Mark II. Using a full-frame camera, you will get a fully circular image when the lens is used at 8mm.
When shooting at the widest angle, you'll notice a blue edging around the circle. It doesn't look too bad when the frame includes a blue sky, but with other subjects it can appear a little distracting.
When used at 10mm (again using a full frame camera), the image is shown with circular sides but with the top and bottom of the circle cut off. At this length, the image isn't really that useful, unless you want to crop to just include the middle of the frame.
Even at 14mm (on a full frame camera again), you will still see some elements of vignetting at the corners, so again it's wise to only use the centre of the image.
At fully zoomed (15mm), the lens captures the whole of the scene up to the edge of the frame. This means that in practice, on a full-frame camera such as the 5D, the lens is most usable at fully wide, or fully zoomed.
The 8-15mm lens performs well shooting directly into the sun, with little to no loss of contrast, ghosting or flare. Cyan magenta fringing can be seen on high contrast edges, such as on the lighthouse.
You can see in this 100% crop where the fringing is evident. You should be able to remove this type of fringing when processing in the raw converter though.
Because the depth of field is so large, you need to be careful of anything that appears on the front element of the lens. In this picture, a stray raindrop can be seen.
This image was taken on an APS-C sized camera, the Canon EOS 7D, with the lens set at 15mm. On a crop sensor camera you have an excellent quality 10mm to 15mm zoom lens does not sound like a large range but it really is!
This image was taken on a Canon EOS 7D, with the lens shot at 10mm.
This image was shot on a 7D at 8mm. At first look this may not be a very useful setting with the vignetting, but most panorama software will convert 4 of these images each shot at ninety degrees to each other into a great seamless 360 degree panorama.
