|Getting the big picture at the weekly market in Tübingen|
In June 2012 I bought a Walimex Pro 3.5/8mm Fisheye for Sony and have used it on the Sony A77 and A7 since then. It is an APS-C lens, so on the full-frame A7 you have to set the camera to capture the photo on the smaller sweet spot on the sensor. Otherwise, you get this:
|The shadows cast by an APS-C lens on a full-frame sensor|
|Creatively adding the foreground to your composition|
Fish-eye lenses are also fun to play with if you experiment enough with them and think of good opportunities for using them.

This shows the vegetable stand in the context of the market. What I wanted, however, was to emphasize the lines of the blue and white awning and the colors of the veggies. As with many of my fish-eye photos, I pushed the "Distortion" slider up to +100 in Lightroom (it works the same in Camera Raw) and constrained the crop. In essence, that flattens out the picture a bit, making it appear as a simple wide-angle shot.
In the two photos below, I experimented a bit more with the position of the camera relative to the awning. In post-processing you can also add vertical lens correction to get the look you want.
With a bit of forethought and some imagination, you can combine several advantages of the lens at once and get close, emphasize the composition and frame the motif all at once. Happy shooting!
In the next part, I'll write a bit about using the fish-eye lens for architectural photography.
