Summary: I have only received the lens adapter, the lens I ordered has still not shipped, so I have nothing to "adapt" with this adapter. When two items are interdependent it would be advisable to hold and ship TOGETHER. As it is I have no use whatsoever for this item, unless and until the lens I ordered is shipped. The only thing I can say about this item is that it was ordered and it arrived.
Summary: It really bothers me that Canon does not put filter threads on their top of the line point and shoots. Its even more troubling that they would design such a horrid solution to that problem, that of the LA-DC58K. There are multiple problems with the LA-DC58K. First its plastic which means the overall quality is much lower than the other options on the market, besides plastic threads are never a good idea as they wear down with time making it harder and harder to properly...
Summary: I purchased this accessory for the sole purpose of being able to use my extensive filter system with this camera. I normally shoot with a DSLR and the screw thread size on all my filters, as well as close-up lenses, is 77mm. After attaching a 58mm to 77mm step up ring, all of my regularly used filters easily attached. There is a catch, however. The mere adding of the conversion adapter will create vignetting at the widest focal length settings on the zoom range.
Summary: makes the G 10 more durable and easier to handle while protecting the lens. A must for using filters. You must remember to remove the front half of adapter when using at the camera at wide angle.
Canon LA-DC58K Conversion Lens Adapter for Canon G10 Digital Cameras

8 February 2009
Summary: I recently got this with my G10 and confirm everything negative that everyone here says about it ,.. A MUCH better alternative are the products available thru [...] they explain what works and what does not and what you need to achieve a given result,.. I have purchased replacement parts thru them and Im very pleased,.. the Canon part is simply sub-par dont waist your money. As far as Amazon goes they were GREAT as always speedy ontime delivery at a great price.
Summary: This adapter makes it nearly impossible to use a polarizer with a G10. With both pieces a 58mm polarizer vignettes badly. The two piece design uses a proprietary 57mm thread in the middle, so you can't attach it there. kind of frustrating. They really needed to make the front threads much larger, either 72 or 77mm. BAD design. So It's only use is for a teleconverter. If you want it for filters don't waste your money, but the one from lensmate.
Summary: Unfortunately I read unfavorable reviews from other sources after I purchased the lens adapter and decided to return this item and the two filters I purchased with it. Two issues...the canon lens adapter is two pieces of plastic with plastic tabs that affix to the camera that I felt would easily break, second and most of all the reviews indicated that the fully extended lens hits certain filters attached to the adapter and causes vignetting....poor design.
