Lens Review Date: February 28, 2015 I can recommend this lens: Yes | Price: $37.00 | Rating: 6 

 
Pros: fun, cheap, massive built
Cons: IQ at corners, NOT 180°
Sharpness: 5    Aberrations: 4    Bokeh: 5    Handling: 8    Value: 9    Camera Used: Pentax K-x   

Bought as used, branded as "Weltblick fish-eye lens 0.15x" but this is the same as Kenko (and other brands). Mine copy came with 49 and 55mm adapter. Front element is rather vulnerable, as any bulged front element. Unfortunately it has some minor scratches, but cannot be seen when looking at the front element. You have to look through at the back to see them. But fortunately doesn't affect image.

The actual FOV is around 170°. None of any rebranded versions has 180° FOV. (AFAIK) I sat mine up in the middle of my garden, around 16 inches (40cm) from the ground, pointing right up to the sky vertically (zenith). Trees and houses further away, around the camera were cut at their top, not 16 inches from their bottom.

As these lens were made for FF SLR cameras to give full circle on 50mm lens on FF. I have some trouble to get full circle on an APS-C sensor. 1.5x crop ratio would suggest a 33mm lens to give full circle, but I get a smaller circle at the middle, with heavy vignetting. (I cannot see the edge of the circle.) At around 40-43mm I have a full circle, but with strong vignetting. I tested on a F35-80mm. Do anyone manage to get a full circle with no vignetting? Do anyone have a FA43mm prime lens to try it out?

Image quality at the edges are poor, but way better than those cheapo 0.25x fisheye lenses found on e*ay and a*azon.
I will put up some images as soon as I get some usable.

Pros: Fis-eye fun, inexpensive, nice build
Cons: Vulnerable front element as with all fish-eye lens, IQ ...
Sharpness: 6    Aberrations: 5    Bokeh: 5    Handling: 7    Value: 6   

Bonjour,

I picked up this fish-eye at a swap meet and it's relatively fun. My copy only has the 52mm adapted and does not have the lens cap, so it's stored in a case.

I have only tested this fish-eye with a K 50/1.4 since it has 52mm threads. I will post some sample images later ... Salut, J
