Question: Hi, somebody can tell me if this adapter fit well in a SX20, because I bought another adapter for SX20 and didn't fit.
Document: Despite what other reviews may say, it is not hard to fit on the lens and takes filters well. I bought 2  in order to keep them on my grad nd and circ. polar. filters all the time. It is minor that it does take some effort to remove a variable ring filter from the ring adapter.
I already had 58mm filters from other cameras, so thought the product was worth a try given the price. Worked perfectly with the Canon SX40--screws on and off very easily. Well threaded to receive and remove the filters. Feels surprisingly sturdy. A warning, however: I've since bought the SX50, and it's a significantly tighter fit on that camera. Much harder to get on and off. You have to zoom the lens out and hold onto its barrel while you're putting on the adapter to make sure you don't put torque on the lens itself when you twist the adapter ring.
Bought this adapter so I could use a filter for lens protection as well as photo effects. Mounted easily and quickly and accepted my 58mm filters with no problem.
I ordered this with a bit of concern. Although the SX20 is listed in the title, the technical details did not include the SX20. But the adapter worked just fine on my SX20.

I ordered what said was a 58mm lens adapter from another seller that said it would fit my Cannon SX40 but I couldn't get it on my camera no matter how hard I tried. When I saw this one I said why not give it a try as it said it would fit (of course the other seller said that too) and when it got here I had no problem putting it on and it fit tight. Love it and finally found a dealer that I can rely on.
Lens adapter fits nice and snug on my SX20 and my filter screwed on nice and smoothly. I'm impressed by the value for the price I paid. The price included shipping and a complimentary magic wipe lens cloth. I placed the order at night and the item was shipped first class the next day.
''This Lens Conversion Adapter worked perfectly for the Essential Kit with the 3 filters that I purchased for my Canon SX40 HS. I am always nervous about ordering items that I can't test to see if they fit right, so was very happy to see these fit perfectly and worked very well.I have had no problems at all, I ordered extra adapters for each lens so I don't have to keep putting them together. I would order from DigitalGoja again as I am very satisfied with the products and the service I received.''
The SX20 does not have a thread on the lens.This &#34;Lens Conversion Adapter&#34; uses what I assume was the mounts on the lens indented for the lens cover, it allows a 58MM filter to be attached to the SX20. My SX20 is a few years old. This allows me to put a clear filter over the lens to protect the lens.Used it for several days of shooting outside and it worked fine.
This adapter worked well for me. While I initially  considered that I might need to purchase the 62mm adapter in the future when I had the spare funds to replace my current filters I now know this will not be necessary as the adapter has fit all of my adapting needs perfectlyA couple people in other reviews complained about being able to see the adapter ring in the edges of the shots but as I said, I already had filters in this size and a lack of excess funds so I purchased this adapter for now and planned to crop any edges that might be a problem.But I never had this problem  I take quite a few shots with  the thicker circular polarizing filter and saw no evidence of it in any of my pictures.
Answer: well i do not own an sx20 but what i know is that the sx series of the compact cameras is that the external design is the same. what differentiate the most is the internal.
