[QUOTE="WayneF, post: 326577, member: 12496"] Macro lenses focus much closer, typically to as much as 1:1 magnification, which the 1:1 means the image size is the same size as the real life object. That could mean for an example, an object one inch dimension (25.4 mm) could make an image slightly be larger than a DX 24mm frame width, or slightly larger than a 24mm FX frame height. In the old days (when we could hold the film and look at it), 1:1 meant the image on the film was the same size as the real object. I am not familiar with your three attachments (can you provide a link that describes them?), but there have been lens attachments (attached in front of a lens) that makes the view be more telephoto or more wide angle. Typically those I have seen were for older cameras without interchangeable or zoom lenses. They would not focus closer. But there are close up filters (basically simply a magnifying lens) that makes the lens focus closer (but not as much as 1:1). [/QUOTE]
