Recently I was browsing through Amazon.com and looking for telephoto lens for my Canon Powershot S5 IS. One particular from Digital Concepts was for sale via D B Roth for $24.99 plus shipping cost. Meanwhile, Canon TC-DC58B lens is $103.96.
After I received the lens from D. B. Roth, the test shot result with new lens was horrible.
In this shot above, without using the new lens, fiber from background's fabric is uniform and in focus through out the photo.
With the new lens addition, only center part of the photo is in focus and outer area is very blurry. It gets worse as further away from the center.
Update: The quality of this lens is so bad that the seller, D B Roth, has refund my money in full without even wanting it back!
