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.

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.

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...

Bought this for my wife to round out her capabilities on her aging G3 camera. What a lark. Took a trip to SF and drove around all day...other than a few user error shots where we had the settings wrong on focus, it did an admiral job of shooting sharp wide shots that added more fun than I have...

This lens performs almost 10x better than I was expecting it. As far as fish eyes come this is by far my favourite simply for size and price alone. Fantastic low-light and extremely sharp for just how cheap this little guy is.Would buy again 10/10

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

I don't have a M43 body. Bought this for my Fuji X Pro 2. Plastic mount easily machined to fit into Fuji X mount from generic extension tube. Photos are very sharp. Much better than I expected since I am using it with a sensor larger than it was designed for.

When I first go this lense I didn't realize it focused by the little lever on the bottom. I just thought it opened up the lense cover, so at first I was shooting with this focused to far and got very blurry photos. Ounce you realize you want to 99% push it to where it clicks a little.

I am very happy to get this one. But i did not have a chance to test the cap/lens yet.

Excellent fun lens. Surprisingly, it gives very good results, for the price paid. Very happy and strongly recommend to all beginners, and others!

La calidad de fotografa que se consigue con este lente es muy parecida a la de un telfono de gama alta (es decir buena, pero no la mejor por supuesto). Hay que poner atencin al enfoque porque fcilmente se puede obtener una fotografa totalmente desenfocada en general.

This lens is nice for landscape photography. I do a fair bit of correction of the perspective afterwards, in order to get an effect that is a bit more wide-angle than fish eye, but it's also fun to have the option to get the distorted perspective too.

Good results at great price.
