The Canon EF 8-15, f4 USM
Fisheye Lens

1 - Introduction

This essay is about a specific lens, namely the Canon EF 8-15, f4 USM fisheye. However, it is also about expressing a personal artistic and photographic vision, the subject of my current focus and research.

Vision can be expressed in many ways and one of them is through the use of gear that allows you to represent the world in a different way.  If you follow my work you know that I distort my images regularly to increase the size of specific elements, to strengthen the composition, or to emphasize the aesthetic appeal of the image.  The Canon 8-15 allows me to do this in camera rather than during post processing. While the possibilities are not as extensive, being limited by what the lens does rather than by my imagination, they are still extensive and worth investigating for their creative potential.

2 - The lens

The Canon 8-15 is a zoom lens. On a full frame 35mm camera, you get a rectangular image with no vignetting in the corners at 15 mm, and at 8 mm you get a circular image. The lens can therefore be used in two ways: to create a super wide rectangular format image, or to create a circular image.

 These two photographs were taken from the same exact location. 
I did not move and did not change any settings between the two captures.
The only thing I did was zoom in from 8 mm to 15 mm.

3 - Why this lens

When I purchased this lens I planned to use it to create rectangular fisheye images.  I had a Sigma 12-24 mm lens which created a flat horizon and I was curious to see the possibilities offered by a lens that distorted the horizon and gave a fisheye look to the photographs.  However, after a couple of shoots I quickly grew tired of tilted horizons.  I simply did not like it and to remedy what I saw as a problem I ended up straightening the horizon in Photoshop with the warp function. The only way to get a straight horizon was to place the horizon in the center of the image, an approach that severely restricts compositional creativity.
This was a counter productive and time consuming approach.  It was simpler to use the Sigma 12-24 or the 28 or 38 on my medium format system and get a straight horizon immediately. However, having invested in this lens I did not want to see it go to waste.  This is when I decided to try the 8 mm setting to get a fully circular image on a full frame 35mm.

I had not tried this before in part because I intended the 8 mm setting to be used on a reduced frame, APS-C, 35mm, such as the Canon 70D for example.  I like these cameras because the tiltable LCD screens allows me to position the camera low to the ground and yet see the image on the LCD by tilting the screen upwards, a feature not available on full frame 35mm cameras.

At first my attempts at creating circular images were spotty.  I would take one or two out of curiosity, without trying to fully explore the compositional possibilities offered by the lens.  It was only after seeing my initial results and getting positive feedback from my audience that I decided to push further.  The images you see in this essay are the results of my creative explorations so far.

The lens comes with a lens cap and lens shade. 
The lens shade must be removed when taking circular images to prevent vignetting.

4 - Exaggeration

When using this lens distortion and exaggeration are the name of the game.  The lens distorts regardless of the zoom setting so it is not about distorting or not, it is about distorting as much and as far as you can. In the horizontal direction you will get a curved horizon at both 8 mm and 15 mm unless you place the horizon smack in the center of the image.  In the vertical direction you will also get distorted objects on each side of the frame unless they are placed in the middle of the image.

But as I said, when using this lens, distortion is the name of the game. I purchased it because I wanted to distort the elements I include in my photographs.  As such, it works like a charm.  It is particularly impressive at 8 mm because the distortion takes place over the entire image circle.

When working with this lens, just when you think you have gone too far you realize you got it right.  For me there is no such thing as slight distortion, especially when working at the widest zoom setting, 8 mm. Instead, composition is best approached by incorporating the distortions into the composition.

I use these distortions in my compositions, letting the image curve until it follows the circular image borders, creating curves where in nature I see straight lines. I like the curvaceous quality the lens gives to both nearby and distant elements.

In this photograph and in the next one, this effect is achieved by getting closer and closer to the subject
until the distortion follows the edge of the circular image.

I got within inches of the plant to create this effect.

5 - Branches

I like to photograph branches by going underneath a tree and shooting up into the sky.  This allows me to fill the frame with branches, small and large, and create an intricate, web-like composition of branches.

6 - Slot Canyons

This lens is ideal in slot canyons and in narrow canyons where space is at a premium and where lenses never seem to be wide enough.  I know this first hand. My work is in part about expressing space and to this end I have used lenses up to 12 mm lens in these canyons, the widest lens you can use without getting corner vignetting on a full frame 35mm.  I have also used equally wide lenses on other formats including medium format up to 28 mm and 4x5 up to 47 mm.

I have also used stitching to widen the amount of area I can capture in one frame.  Stitching images is in fact a staple of my workflow because it allows me to expand virtually infinitely the amount of space I can capture and represent in one image.

However the Canon 8-15 gives me yet another way to represent space, this time by creating circular images in which elements are distorted along the round borders of the image.  As such this lens becomes part of my wide angle arsenal, yet another tool I can use to create exciting compositions that are rarely seen and that allow me to express my vision of space and beauty in the landscape.

7 - Sun star

I like to include the sun as an element in the photograph. Doing so increases the dynamic qualities of the images while adding a dash of color and energy. This is best done by depicting the sun as a sun star, something which is achieved by closing the lens to the smallest f-stop and shooting through an element to diffract and reduce the brightness of the sun.

With the Canon 8-15 doing so is easy because the wide coverage of the lens reduces the sun to its smallest size.  The visual quality of the star, which is a function of the quality of the diaphragm construction and of the number of blades, is also very nice, with multiple branches and a very nice look overall.

Depending on what the image composition calls for, I place the sun star in a variety of locations in the image, anywhere from smack in the center, to off to the side to all the way to the border of the image.  The three images below provide examples of these three different approaches.

8 - Getting yourself in the photograph (or not)

Not getting yourself or your shadow in the image is challenging to say the least.  The lens is so wide that one has to be particular vigilant in order not to do this.  However, on the other hand, the lens offers an easy way of being in the photo, in whole or in part, either by including parts of your body or including your shadow when the sun is behind you.

The shadow is myself.  That’s one way to get into the photograph!

9 - Getting a white background

Circular photographs come out with a black background on a horizontal frame.  If you want to get a white background, like I do, you need to use the Elliptical Marquee selection tool in Photoshop. 

The process is simple.  Start by selecting the Elliptical Marquee selection tool in Photoshop. With this tool selected hold down the shift key to get a perfect circle.  Then select the inside of the image, invert the selection, set the background color to white, press delete and voila!  After doing this I crop the photograph to a square format to give equal borders all around the image.

Additional photographs that I created with this lens are available in the Fisheye Photographs Online Gallery on my site.
