|Olympus 9mm f8 Fisheye Bodycap lens|
Second, it's considered a 'fun' lens to have. Something that takes up no room, you have with you all the time, and you use on the odd occasion just for a different effect. The fisheye look can quickly become overdone, although the 9mm (18mm equivalent) Olympus bodycap fisheye has a slightly narrower 140 degree field of view (as opposed to the traditional 180 degree angle of view of a traditional fisheye lens).
As you can see from the specs, the bodycap is only 12.8mm thick, 56mm in diameter, weighs just 30 grams, but manages to fit in 5 glass lenses, 2 of which are aspherical elements for image correction (although the lens is still prone to chromatic aberration in high contrast areas).
Olympus have previously released a 15mm bodycap lens, but the image quality was not up to much, and it didn't really make sense to me since I already own the tiny 17mm f2.8 pancake. But a 9mm fisheye! That's another story. And with the inclusion of 2 aspherical lens elements, Olympus is obviously taking the IQ of the lens fairly seriously. Although having said that, the 9mm bodycap lens is not given the 'Zuiko' brand name. It's considered more of an 'accessory' rather than an actual lens. So given all that, how does it perform in real life?

The extreme edges are a bit soft and blurry, but the rest of the image is acceptably sharp, to very sharp in the central portion. Images from the 9mm bodycap would print up to A3, and maybe even bigger with some localized sharpening applied.
The extreme edges do have some purple fringing, especially in high contrast areas, but this is easily fixed in software like Lightroom.

Since it's a bodycap, there isn't any thread to attach a lens hood or filters. And with such a wide field of view, it's almost impossible not to include a portion of the sun in some of your images when shooting landscapes. Fortunately then, the 9mm fisheye bodycap controls flare extremely well, although I'd still want to avoid shooting into the sun whenever possible.
I might also try placing a square cokin filter in front of the lens while shooting, just to see if I can use filters without getting my fingers in the shot!?
The photo above shows a small amount of flare in the top of the image, but it hasn't affected the contrast too badly, and the rest of the image is perfectly exposed.

The result was exactly what I was after. The lens has kept the middle of the image nice and sharp, but getting up close has really exaggerated the fisheye effect around the edges of the frame. Pretty freaky, but also pretty cool. And a lot of fun. Which is exactly how I described this lens at the start of this post. Just plain FUN.
Maybe you shouldn't take the Olympus 9mm fisheye bodycap lens too serious? Maybe that misses the point of this accessory?
But, then again, maybe the IQ from this lens warrants a serious appraisal. It's a piece of kit that can be used to capture some seriously good images. If you're in the market for a fisheye lens that won't break the bank, you need to seriously consider the Olympus 9mm Fisheye bodycap lens.
Best birthday present ever! Thanks honey :-)
