good value prices in 2382

Well worth the price paid. Of course the fact of adding this supplement reduces the optical sharpness of photos and there a lot of chromaticism on the edges of the image accompanied by a deterioration in the quality of the image.
It is a complement to want to discover the fisheye or run some tests on the cheap.
Fits seamlessly on the basic canon 18-55.
The design could be improved by adding a matte black washer or by shading the lens edge "fisheye" to avoid problems in bright light (for me I simply cut a black washer sandwiched between the lens "Fisheye" and lens 'macro').
