Verdict

So what is the Olympus Lens Cap 15mm f/8 - a lens or a cap ? If you are expecting a conventional lens, better consider it to be the latter. In pure technical terms it is one of the worst 'lenses' that we ever tested. That said - the center performance is actually surprisingly good. However, the real problem is that the quality drops dramatically reaching barely acceptable results in the mid field and a blurred outer image region. The contrast level will not make you rave either. If you are a cheerful fellow, you may consider the comparatively low distortion as a strength. The amount of lateral CAs and vignetting isn't hot but not dismal either.

The key selling point is the marginal size and weight - thus its coolness factor - but remember that the micro-four-thirds pancakes (Olympus 17mm f/2.8, Panasonic 14mm f/2.5 & 20mm f/1.7) are no bricks and these are 'real' lenses. Despite being an Olympus 'lens', it actually shares a couple of characteristics with caps in that it has no electronics so it doesn't offer AF nor is it capable of producing EXIF data. Using the focus lever isn't a joyful experience but it works out once you got used to it. The build quality is acceptable although the focus lever doesn't feel overly solid. That all said, we still have to put things into perspective - the lens cap costs 49$ in the US (albeit much more in other regions) so for Lomography the thing is always good enough if you are ready for such type of fun. As for the rest ... better look elsewhere.
