Rating: - Excellent item, you get what you paid
The zoom increase when taking the pictures is significant, the lens mounts fairy well with almost no loose movement, if your looking of a teleconverter this should be it.

Like anything you buy you get what you pay for,I was thinking about buying another brand and I am glad I didn't,this lens works well and I can tell that the 1.5 does make a difference.the lens is clear and is multicoated,it does what I want it to,as with any other saying buy quality its what you get.It does have a barrel effect when in close mode but the lens is not made for that,in telephoto the barreling disappears,but it makes a neat effect on close images,almost like a round frame.it threaded on the adapter with no problem,its a keeper.Also included is a nice drawstring pouch and caps for both lens ends.
Rating: - Use the hood !!
For those complaining about not being able to use the tele-converter with a filter, note that the hood included with the adapter is threaded for 58mm filters. The hood does not stay secure over the lens, but if you carry a small roll of tape, you can use a couple pieces to secure it.
I have only used this in practice, but came out with some very good, clear results. Like others, I know this is a zoom lens, but wish you could be able to back off the zoom a bit with out getting the tunnel effect. I think it will work out well, though. As to price, it's fair, especially as DSLR lenses run in the thousands, not mere $200.00 and less. Oh, yes, I purchsed this lens from Canon, and the
Amazon price is considerably less.

This takes amazing pictures.
I read one review that said that there is a circle when not zoomed in. This is true, however, this lens is made for reaching out far. So if you put it on and dont want to use the zoom, you are a pinhead. Here is an example of the circle http://outdoors.webshots.com/photo/2445322610046342862IUtNrR?vhost=outdoors
Here is an example of my camera without the lens

This is with it

You can see how much it reaches out.
One warning. You have to get the adapter for this. They run about 24 bucks. I got two, one for my tele and one for wide, so they are easy to switch out

Rating: - Warning! May not be what you expect.
I just received the Canon TC-DC58B and put it to the test. I took non-digital zoom shots, at full magnification, with and without the converter and was instantly disappointed. What disappointed me was that the extra magnification I got was a lot less than I expected. There was little difference in the two shots. In fact, I could get the same magnification by minimally employing the digital zoom feature. I am going to Alaska for the first time soon and was hoping the lens would help me get up close and personal with nature. I doubt it will get me much closer at all. I've read through the reveiws and would agree with the quality of the lens, etc. I don't see where those who rated this a 4 or 5 even mentioned the fact that you will not get much closer with this lens. I don't like spending over a $100 for something and being left with the feeling that I did not get much bang for my buck. Beware and think twice about buying this. Don't expect a lot.
