Gives excellent results with a simple Photoshop adjustment,
This review is from: Digital 0.45X Professional Wide Angle Lens 58 MM with Macro High Definition (Electronics)
Two tricks make this adapter really useful and versatile: a step-down converter ring, and one simple Photoshop adjustment.
It converts my 28mm equivalent lens to what I roughly estimate is a 21mm lens--a big increase in angle of view.
I got one of these adapters for my Olympus micro 4/3 camera, to try out as an alternative to a $600 true wideangle.
The big problem is substantial barrel distortion. Also, there is chromatic aberration in the corners and some vignetting (darkening in those corners). Now, here's the trick: Photoshop Elements (and, no doubt, other photo management programs) can eliminate the barrel distortion in: Filter/Correct Camera Distortion/Remove Distortion (try +20 to +30%). This has the huge additional benefit of pulling the corners out of the picture without reducing the wide angle of view--the very corners where both the chromatic aberration and vignetting occur! Crop to make the picture rectangular, and you have reduced all 3 problems significantly with this one adjustment.
Now, you still are not getting top quality. But for the ridiculously low price of this lens you are getting 50% or more of the quality at a twentieth of the price of a "real" ultrawide.
FItting the adapter to your lens: I use a Digital Concepts adapter on my micro 4/3 14-42mm lens (28 mm equivalent at wide angle). I have to say that the lens' focus mechanism struggled to work--the motors on this tiny lens must be too weak to move the added weight of this adapter--and I therefore found it best to use manual focus. Other cameras may not have this issue. I actually used Digital Concepts' "0.45X Professional 43mm Wide Angle HD Lens with Macro" which has a 43mm screwthread, closer to my specific need, and I had to also buy a 43 to 40.5mm stepdown ring. The adapter on this page, for the "Olympus Evolt", has a 58mm screwthread, which fits the 4/3 (not micro 4/3) lens. The same Digital Concepts lens adapter is sold on Amazon fitted with a variety of other screwthread sizes.)

Vignetting is SEVERE with the 4/3 Zuiko 14-42mm for which this converter is recommended. Combined with the linear distortion (which CAN'T be entirely fixed), the SIGNIFICANT reduction in image quality, and the degraded auto-focus function, this is not a useful accessory.

do you know if this item works on my olympus digital lens 14-45mm ?? i also have a 40-155mm

It should do. Your 14-45mm lens has a filter size of 58mm. Therefore you should be able to attach this device directly to your lens without a step-up ring.
Don't use it with your 40-150mm! That would be pointless.
