I'm speculating I am going to have quite a few of these, so I figured I might as well start a thread for them. My fellow n00bs are more than welcome to use it also. Anyway... question #1...
I was surfing ebay today and come across something called a macro filter... can someone explain to me what it does? I'm guessing it helps with the blur you get surrounding the focal in a macro image, but not positive.
Thanx, Jack

Generally, these help your camera focus closer, so that small items will be magnified (by virtue of the fact that you will be closer to whatever it is that you are photographing). A by-product is that the background may become more blurred more easily.

A "macro filter" is basically a magnifying lens you screw on the front of a normal lens. Think "magnifying glass"; that's what it is. They come in different strengths, defined as "diopters": + .5, + 1, +2 etc. Bigger number = more magnification.

they're great for bug macro's as it allows you to be a few inches further w/ the same magnification had you not had it(but closer of course). And you do lose quite a bit of dof with them.

To add to the good info laready posted, there are two varieties of these, single-element and doublet. The latter are defintiely the ones you want. The only ones I KNOW are doublets are the Canon 250D and 500D.
The single-element designs are guaranteed to give bad chromatic aberration.

with a fixed lens camera (nikon5700) my infant lens craving was quickly filled with the canon500d.. it really is a great little 'lens/filter' most of my macro's on my site: //totaldis.fbeye.org are done with the nikon5700+canon500d.
