Actually, it isn't a complete lens, its a conversion lens for my Canon 18-55 "kit" lens. This one simply screws onto the outer lens ring and provides... well, have a look!
Original; or with enhanced lens flare...
I thought this last one was hilarious - the svelte, flowing lines of the Green Machine are turned into something that looks more like a Charger!
There's plenty of distortion around the edges of the image, but for less than a 10th of the price of a pukka fisheye, I'm certainly not complaining (especially as this one splits in two to become a macro lens as well!)
I'm looking forward to messing about more with this lens... stay tuned!
