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.

Any high multiplication teleconverter is going to give problems. There's nothing you can do about it in the camera.

If you were going for one I'd get the Canon one because that will be designed to go with the camera, but the result still won't be perfect. Converters are extra glass that will always affect the image.

There don't seem to be any reviews or catalogs for the Tokina converter anywhere, that I can find, or even any acknowledgement of the product on a Tokina site. Maybe someone else makes them for Tokina.

Another company that does them is Raynox (www.raynox.co.jp) and their site gives examples taken with the Canon S2, so you can see the real results.

The DCR-2020 is 2.2x multiplication.

Some reviews/thoughts here
