Hi,

I am very new to digital photography, and a couple of months ago, I didn't know what SLR meant. I bought my Canon S2 and was very impressed with its optical zoom, so I wanted to take it to the next level: tele-photo.

The standard Canon teleconverter for this camera gives 1.5 magnification, so I opted for (the cheaper) 3x Tokina from eBay. However, the image quality is poor to say the least. Here is a picture of the moon without the teleconverter:



and here is the same subject with the teleconverter (same camera settings). The image is very soft with high colour distortion.



Here is another example of a photo taken with the teleconverter. Notice (again) the colour distortion at the edges of the maple leaf.



Do I need to use a filter with this lens ? or are there special camera settings for using a tele-converter that I should try ? And by the way, here is the tele-converter in question.



If my problem with this teleconverter cannot be solved, can someone suggest a different high magnification tele-converter for Canon S2 IS, or should I just stick with the one Canon makes for this camera (TC-DC58B).

Your input is appreciated.
