This basic fixed aperture fisheye lens for Micro Four Thirds system cameras offers a very wide field of view of 140 degrees, with the barrel distortion effect you'd normally expect from a fisheye lens.

After taking both daylight and long exposed shots, I found this to be a great lens. My long night shots showed the white and red streams of car lights really well, using my tripod. Buy this lens, you will enjoy using it. Jim, Charlotte, NC.

A while ago we reviewed the Olympus 15mm f/8 Lens Cap but, honestly, we weren't all that impressed. After all, there are several available pancake lenses around this focal length so there is a rather limited appeal in such an offering in our opinion.

There are probably more reasons for owners of Olympus CSCs to invest in this lens than the previous 15mm Body Cap lens provided. For starters, the local price is very much closer to the US online price (and probably close enough to make it cheaper to buy locally than importing it as discounting...

Worth the money to squeeze in a shot in closed spaces as well as a panoramic landscape. The product is made in Thailand

This is our first ultra wide lens, so I have nothing to compare with. As the price was reasonable we thought it was worth buying, To our surprise it really is an amazing bargain.

Lightweight; Simple Controls

Flimsy Construction

The Olympus Fisheye Body Cap Lens 9mm is the fish-eye lens for photographers who aren't sure if they want one. At $99.99, it's an easy purchase to make, and its slim, light design makes it a fine choice for any Micro Four Thirds camera. Now, its optics aren't perfect—the center is sharp, but edge quality suffers and there's a lot of color fringing in high-contrast areas of the frame—but you do get what you pay for. If you're looking for a fish-eye lens with superb optics, consider instead the Olympus M.Zuiko ED 8mm F1.8 Fisheye PRO ($999.00 at Amazon) or the Panasonic Lumix G Fisheye 8mm F3.5 ($797.99 at Amazon) . DesignLike the similar Body Cap Lens 15mm ($49.59 at Staples) , the Fisheye Body Cap ($99.99 at Amazon)  is really small and light. It measures just 0.5 by 2.2 inches (HD) and weighs about an ounce. Its barrel is all plastic, including the lens mount, with a simple glass lens with a fixed f/8 aperture. That narrow f-stop means that you'll have to push your ISO high or e...

The Olympus Fisheye Body Cap Lens 9mm doesn't have the greatest optics, but it's a fine choice for photographers who want a fish-eye look that won't break the bank.

Inexpensive; Wide field of view; Crisp center; Slim and light

Blurry edges; Noticeable color fringing

When we started testing the Olympus 9mm f/8 Fisheye Body Cap lens, we fully expected it to perform at the level of “toy lenses;” but this ultra-thin, ultra-lightweight lens has surprised us with more than decent images that only suffer from soft corners and comparatively high levels of chromatic...

Olympus' tactic of playing down the optical performance of this lens need not be necessary. Even though this lens only costs £90 and is little more than a body cap with some glass in it, it is still capable of delivering decent quality images.

A formal test of the Olympus 9mm f/8 Fisheye Lens Cap is a bit unfair, of course. After all Olympus doesn't even list it in the range of lenses on their website - it's merely mentioned as a camera accessory thus also the "Lens Cap" name.
