Question: The Powershot sx50 book) they recommended the 67mm filter and adapter for the camera, yet this advertisement is for a 58mm. Which is correct?
Document: This is such an amazing deal. Prior to my Sx50 arriving I started looking for a 58mm adapter ring and a UV filter. I had read many negative reviews about the 67mm that Canon recommends. When I found this kit I couldn't believe my luck. Here was everything I was looking for and at a price that is half of what you would expect to pay for a single, used polarizing filter. Everything fits perfectly and is well made. I love that four-filter case.
I ordered this filter kit for my new Canon Powershot SX50 on the basis of other reviews that recommended it for my camera. Just like they said, every one of them fit just beautifully. The set arrived the day after the Canon was delivered so I got to put it right to use. I'm in love with my new rig! No more lugging around a big camera with a heavy zoom lens!
So much nicer than the 67mm package I had ordered first. THIS IS PERFECT and the new camera is now complete. I HIGHLY recommend anyone w/ the Canon PowerShot HD50X order this package!
The whole sets well made. The filter adapter fits my Canon SX-50 perfectly. The included filters are just great and the lens cap is a nice fit. Additionally, as they should, previously owned 58mm filters fit the adapter just fine. Highly recommend. Goja shipped quickly and well packaged.Botton line -  Just ordered a second set from Amazon (Goja) a a gift for another SX-50 owner.Update:  Used the camera with the above attachments and extremely happy with the kit.
This kit is perfect for my Canon SX50. The adapter ring goes on easy and enables the use of any 58mm filter. Worth every penny!
Item arrived ahead of time. Very pleased with the kit. It fits well on my Canon Powershot sx50. Love it and would recommend product to anyone who has one. Great seller and great product. Thank you.
Just got this. As promised the 58mm filter adapter does not cause vignetting even when the SX50 is at widest angle. The rubber hood, however, does show vignetting there. This can be overcome as long as you remember to retract the hood with your fingers when shooting wide-angle - just something to keep in mind. I was very pleased that a lens cap was included to fit the filters, since the original lens cap no longer works when filters are mounted.
I think it was a good deal. About a quarter of the price for items from the camera store in our area. They probably are not original equipment and a bit cheaper, but they do the job.The other issue was the confusion concerning the correct adapter ring for the Canon SX50. The adapter ring in this set fit perfectly. No issues.thanksSteve
I recently purchased the canon sx50. I researched several filter kits for the camera. I decided to purchase the len kit from Goja and i'm so glad I did. I received it ahead of the scheduled delivery date and was packed well. I am so impressed with the gojo brand i just ordered another set of nd filters from the company. I am not a professinal just a average guy who loves photography and this filter kit is outstanding.
Although the description says this kit is for the Canon PowerShot SX50 HS, it did not fit the camera. Nothing in the kit the lens cap, adapter, etc. fit.
Answer: The 58 mm filter is the correct size for the canon sx50hs camera. I don't know why the canon book calls for 67 mm. Most books that come with new cameras are garbage anyways. You just need too be careful screwing the filter on the lens as not to strip the threads. When putting it on screw it on slowly and then it will stop , but then you need too finish the tightening by turning a little more until you feel it snug.  This is the proper kit. This company will help you if you email them.
