I currently have a canon sx30 (35x optical 130x Digital) Is and it give bad photos for coins, I can't zoom at all(Even optical) or it screws up the picture and takes away all detail so I basically have to touch to coin to the lens and that still isn't even close enough I have to then crop the picture so the coin is bigger So I wanted to know if this is a good microscope.

Read the customer reviews on the link you provide - that should pretty much tell you. The summary is - it does not work with Vista, is a little tricky to focus, but seems to work OK with coins for the price.

I'm not a big fan of these. It uses LED's for lighting and most images I've seen are grey colored regardless of what coin is being photographed. Most times when you are shooting a coin, you need to be able to move the lighting around to highlight (and to create shadows) to emphasize certain details.

There are microscopes that are capable of producing extraordinary close-up pics but these instruments will run around $400 and up.

I've posted a thread in this forum that shows how to get close up pics using just a camera and a loupe.

A desk lamp, a cheap camera and a loupe (or in this case an eyepiece from a broken video camera)

produced the pics below. Bear in mind I just shot these quickly without adjusting the lighting.

That's the one I have.That's a good price too.I paid $60 with S/H.If you type 44302 in the search box upper left of page you will find some info on it.It's a good scope for the price but you will have to block off some of the LED's and play around with it for awhile.

I'm not sure you're getting the best out of your camera. With 14MP in hand, and Canon's known strength with Macro, I'd be surprised if it can't be made to work well for you.

What settings are you using?

OK, good start. The fact that you're aware of the settings is what I was looking for, and they're a good base point for minor adjustments later.

Now, what's happening that you don't like? To my mind, a result similar to the full-face Lincoln reverse ikandiggit posted above shouldn't be out of the question for your camera.

I just ordered this, but I can still cancel it... Should I keep it or cancel, it looks good rather the micro scope

Of course. This is essential.

Don't use the zoom; rather, adjust the distance between the camera and coin with the lens zoomed all the way out. I'm guessing if you start at about 12" from the coin, you'll start seeing acceptable results. Maybe not as large as you like, but that can be fixed. For the moment, concentrate on getting images that are in focus and the right color - the rest can come later.

The cardinal rules of coin photography:

1. Camera needs to be on a firm mount. A camera stand or tripod, so as to minimize shake. Yes, some take decent pics handheld, but not everybody has hands that steady and if you can't do it right every single time, you'll just frustrate yourself.

2. Camera and coin exactly parallel. Macro photography involves very little depth of field, and the minute the camera tilts relative to the subject, you probably lose focus across the whole surface of the coin.

3. Delayed or remote shutter. Remember, miniscule depth of field. If you shake the camera even a tiny bit while pushing the button, your photo will not be in focus.

Learn all this first. An add-on lens will only make that process more difficult, because the "sweet spot" where everything works correctly will become much smaller.

I can't express an opinion about your purchase, I have no experience with that lens. I will say, there's stuff in there you don't need - as in, everything except the lens itself - for coin photography. The lens kit itself is available for $18:

http://www.amazon.com/Vivitar-Close...87971&sr=8-4

Even if it turns out to be crap, I'd spend $18 to find out.

Optics is an area where you very much get what you pay for, but on the other hand coin photography is among the simpler photographic tasks for a given lens. It's quite possible that a cheap macro add-on will give acceptable results under such strict conditions.

Don't forget, though, unless you get the basics down pat, anything you add will only frustrate you.

I don't have experience with that specific camera. However, I've owned an S2 IS and SX1 IS, both predecessors in the same line as yours. Both of mine were OK, if not fantastic, at imaging coins. I'd expect the extra megapixels to buy you a little more distance between camera and coin to get an image the same size.

Like I said, start around 12" and see what you get.
