Hannah and I were experimenting with my fisheye lens today...can you see the slight distortion in the center of this picture? (Can you even stand those blue eyes - unretouched, unphotoshopped! All I did was crop out some ugly background stuff, and bump up the contrast in this pic...since it is purely experimental, we let the flash do its thing. Ordinarily, I find any and every possible way to never, never, never use a flash.)
And Timothy's "fishy-face" here, was totally by chance - hilarious!
You can't tell by this shot, since it is cropped, but fisheye lenses capture 180 degree, wide-angle field of vision, with anywhere from slight to very exaggerated distortion in the center. They are fun for slightly whacky family or group portraits, great for shooting flowers in macro, and photographers more skilled than I use fisheye lenses so they can capture close-up sports/action shots while also capturing context with that 180 degree field.
Here is a silly shot, but it will give you an idea of the wide angle of this lens:
Me, in my jogging pants. Sitting on my bed. In my very messy bedroom, with guitar amps, guitar, my treadmill, all sorts of stuff that needs to be put away. Unfortunately, it has been a busy week last week, and you can see the whole mess, left to right, top to bottom...you can even see my ugly jogging pants.
I hate that for you.
But fisheye lenses are fun.
