Hey Superdave (Or Other Experts), Canon S2 Question

If I remember, I worked in Macro rather than Super Macro. 6-8" from the coin, autofocus always, and it's that big because that's what the camera gave me.

The advantage of a lens like the 250D or 500D lies in its' ability to let you place the camera further from the subject while getting the same final image size. I strongly advise that you learn the camera before deciding to attach another lens - that way lies frustration.

Play. Learn the camera. Try every setting. As a rough starting point, use full Manual mode with settings like this: f/5.6, ISO 200, 1/100 exposure. That'll vary with the light but the first shot will let you know what direction to go.

Feel free to post any results here, and we can walk through the steps to correct any problems.

Last comment, on the Amazon link: you get what you pay for. There's a reason why a 500D is close to $100 and those sets are less than $20.
