I figure spending $20-$50 for a filter is better than buying a $6,000+ lens that I can't afford. Will these filters degrade the image quality at all?

If not, any suggestions on a nice quality 2x or 3x 58mm filter for my 75-300mm lens?

I'm not sure what you mean, but it sounds like I want one too, haha. Do you mean a teleconverter? Cause I don't think you get get those for the price you mentioned.

why not go for some extension tubes like Kenkos
Kenko Extension tubes

they work very well, NO optics to worry about, down side is you may have to manual focus and your depth of field can get REAL small. But other than that they are awesome

interesting with the extention tubes. What exactly do they do? And how much do they change your zoom? Is it like adding a 2x or what?

So...how do these work? I attach the lens to the tube and the tube to the camera? How big is the magnification?

well, a macro lense isn't like 6 grand... but still, the closeup filters won't achieve the same thing. they will get you a little 'closer' but every piece you put in front of your lense degrades image quality to some degree. extension tubes will get you more than the close-up filters will, if you're going for macro capabilities.

i would suggest putting a screw-on type of teleconverter either. they are generally of lower quality than one that would go inline between your lense and camera body. if you do want to put a 2x on your 300mm, i'd recommend you get a regular cannon TC. just remember you'll lose some light, and sharpness.

the extenstion tubes go between the camera and the lens. they allow you to get much closer to your subject. Im not sure how to calculate the magnification per extension tube.

here is a shot usnig all 3 extension tubes in the set (12,20 & 36mm) and my canon 50mm lens


this one was done using the 12mm tube and my 28-200mm Quantaray lens


and here are some more shots using various extension tubes and lenses

I'm not really looking to use it for macro per se, just something to get me a little closer to my subject. I just find it too difficult to get a decent shot of a hawk or bird when they're so far away and a 300mm just won't hack it. If a magnifacation filter will really drop down the quality I guess I really should invest my money into a new larger telephoto lens or ever a teleconverter like you suggested.

oh..the extension tubes are NOT going to work for what you want, the extension tubes you have to be inches from your subject.

you just need more power or more reach. a teleconverter or the likes is what you need, but once you get into that high end range you need to be sure you have a very steady hand or a good tripod to prevent camera shake.

I agree
a teleconverter is what you want...I bought a 2x that made my 300mm into a 600mm...works great

You want a Tele Converter, or a bigger lens. Problem with a TC is it reduces the speed you can soot at at a given apature. Birds are fast, and unless you can get down near 2.8 now a full 2X TC may be too dark for you. Try before you buy. We all want to get closer cheaper, but it is a trade off. I got the 1.4 tamorn TC which work fine, sort of ok for when you really really need the extra reach, but I decided that the 2x was just too dark.

Really? I wouldn't mind seeing a few samples if you have any.

Thanks for the help everyone.

Do you have to have a SLR to use those tubes? I have an OLY C-4000Z, and I can get add on lenses and filters. Any one know if the tubes will work as well?

if you put a 2x tc on a 300mm lense, i hope that lense is a fast lense, cuz i know a lense with a f/5.6 at 300mm will probably not autofocus too well with a 2x tc on it :)

I'm pretty sure you do need an SLR for these.

Close-up filters can be used on any camera with a filter thread on the front. They don't let you get anywhere near as close as some of the examples I've seen here, but I couldn't live without mine.

I bought some filters (hoya brand) a few years back. The amount of use and good fun i've had (and photographic successes, of course!) greatly... GREATLY outweighs the small cost.

I got the same 1x, 2x, 4x filters with my set too.

Just out of curiosity does any have or used the Quantaray - 58mm +3 Close-Up Filter? I can't seem to find a review anywhere.
