It's O.K. but for the price I dident expect much. The Wide angle isn't very wide, and creates quite bad CA in the edges of the image. The macro is great fun and seems to create a good image at a fraction of the price. Build quality isn't the best, the thread is not that good but i'm only screwing in to a filter & not the lense.
I have had Kingston products in the past and they have been great quality, durable items. Unfortunately this is not the same. I have returned the first one for a replacement that was exchanged very quickly (thank you) and the second one has the same problem, the USB connection is lose and keeps disconnecting. I can't be bothered to change again just going to get a different brand and drop this one in the bin.
I have a number of the Wagner DVD's and they are all very poor. The theme is all the same "find the ball" and using slow motion video of top players contradicts the majority of his technical teaching points.
