Lens Review Octobre 2014 Sharpness: 8 /Aberrations: 8  /Bokeh: 8  / Autofocus: 9 /Handling: 8,3/10 /Value: 9/10 /Camera Used: Pentax K5    
Pros: Small - sharp - flexible
Cons: 1.5 multiplyer on DSLRs eleminates much of barrel distortion inherent to semi-fisheye lenses but it's a perfect wide angle.
I would strongly recommend this lens to a friend.

I just received my copy of this lens which I bought on eBay Japan(btw, and excellent eBay vendor) for $167 + $20 S&H. This is one of the sharper lenses I have. The "fish-eye" effect which it is designed to produce on film cameras is somewhat diminished on a digital SLR, but still there.I bought this after testing it on my K5 and realized that it was an excellent wideangle zoom (equivalent of 25-42) for DSLRs. There is moderate barrel distortion that I realy remove during post-processing.On a film SLR, it performs as expected. Great for the few times I need a "different" perspective. Since I rarely go for the fisheye effect, I'm truly happy with it as a wide angle zoom on my DSLRs.
