The Opteka .45 X wicon for the Kodak Z740 (55 mm mount)
#1

I received my lens today. I purchased it through Amazon.com at a cost of $20 (of course it ended up costing me $60 with shipping and cross-border fees). The lens feels very good, solid. There is a nice grip to it. It comes with a leather-like lens case and front and rear lens caps. On my Kodak Z740 (38 mm equiv-wide angle end), the lens produces an image like a 17 mm lens. As far as I can tell the image is adequately sharp. There is little light loss. There is slight vignetting in the upper corners visible in some shots.

Trial photos follow. Of course I did some post processing--couldn't resist it.

I tested the coverage of the Opteka converter and discovered it is acting like a 28 mm lens equivalent rather than a 17 mm lens equivalent.

True Poop and Scoop

The Opteka wicon is functioning as a 28 mm lens. The back of the lens (the end that attaches to the camera) is a 2.2x macro filter which actually works rather well apparently.

The rest of the lens does appear to generate a .45x image when the macro lens is not attached. The image is very unsharp, however, and the lens does not fit on a 55 mm mount. The following test was taken wuth the lens (without macro) held in the adapter by hand.

So we have a .45x lens (that doesnt fit the camera) reduced to a .7 (or so) wide angle effect by the macro lens attached to it.
