Hands On: Canon EF 8-15mm F/4L USM Fisheye
28 September 2011
Excerpt: FROM OUR EDITORS AT PHOTOKINA: We got our hands on a couple pieces of new Canon glass tonight, including their upcoming 8-15mm f/4L fishey zoom. The Canon rep informed us that the pre-production unit we were checking out may actually be the only one like it in Europe at the moment.
Summary: Crucially these capabilities fill a number of gaps in Canon's lens catalogue. Previously only one of the four configurations mentioned above was possible with a Canon branded lens, and it was decades old. The ageing EF 15mm f2.8 prime lens could deliver 180 degree diagonal fisheye images to full-frame bodies, but there were no Canon-branded fisheye options for owners of APS-C or APS-H bodies, nor has it ever offered a full circular fisheye option for any of its cameras.
Pros: 180 degree diagonal fisheye for all Canon DSLRs., 180 degree circular fisheye for full-frame DSLRs., Tough build with weatherproofing., Optically sharp across the entire imaging circle.
Cons: Vulnerable-looking front element., Lens cap easily comes loose., Chromatic aberrations in areas of high contrast., Full circular fisheye only available to full-frame.
Excerpt: The EF 8-15mm f/4L Fisheye lens is a highly-anticipated and unique lens in Canon’s lineup. I’ve been using it for a couple of weeks now and will give a hands-on “user report” review of it below.
Excerpt: Every so often, a product comes along that just blows you away - one that completely makes you rethink your photography. The Canon EF 8-15mm f/4 L USM Fisheye Lens is, without a doubt, one of the most radical lenses Canon has introduced - and it is a game changer for photographers.
Excerpt: The fisheye camera lens was originally developed so that the whole sky could be captured in one single image to help meteorologists study cloud formations. However, the extravagant 180-degree angle of view soon found favour with photographers.
Pros: Dual circular and diagonal fisheye options on full-frame cameras, very good image quality, excellent L-series build quality and ring-type USM autofocus
Cons: Lacks circular/diagonal versatility on APS-C and APS-H cameras, fisheye distortion effect is minimised at 15mm on an APS-C camera, very expensive for a fisheye lens
Excerpt: This unique lens offers two lenses in one for full frame camera users. At 8mm it provides a circular fisheye image, with a 180 degree field of view in all directions. With the lens zoomed to 15mm, the lens offers a diagonal fisheye image, with a field of view of 180 degrees from corner to corner.
Pros: Excellent sharpness, in the centre of the image area, Superb build, Unique zoom design effectively gives full-frame users two lenses in one, Useful for owners of multiple Canon camera formats
Cons: Expensive, No way to lock the lens at either end of the focal range, High CA levels towards edges of the picture area
Excerpt: In February 2010 the Sigma company presented a new lens, the Sigma 8–16 mm f/4.5–5.6 DC HSM. At first glance the Canon EF-8-15 mm f/4 L Fisheye USM is a very similar device but after a more thorough examination you see only the focal lengths’ range of both instruments is alike. First of all, the Sigma lens was designed for smaller APS-C/DX sensors.
Cons: chromatic aberration momentarily a bit too high.
