Close Up

Hi

What sort of quality should i expect when using a reversing ring with a standard lens. I know you can't beat a true macro but as cost at the moment is an issue i thought i would try this alternative. Or what about a macro converter used with a standard 50mm lens.
I will be using it on a K10D.

Pretty damn good.

Personally I'd use an extension tube. The problem with reversing rings is that you have none of the auto exposure/aperture controls so have to experiment with each shot.
Can pick up auto extension tubes or macro converters pretty cheap secondhand.

Yes i did consider extention tubes but was curious as to what a reversing ring would be like as it would be permanently fitted to a lens. I've seen a vivitar macro converter for sale and was just wondering whether i would get good results with older 50mm pentax lenses.

It's no more permanent than the extension tubes. You attach the reversing ring to the K-mount, and screw the front end of the lens on to the ring.

Or the other type, you attach the first lens to the K-mount, screw the ring on to its front, and attach the second lens, reversed, by screwing its front to the ring.

It all comes apart just as easily as the tubes.

Sorry when i said permament i meant so that i woul'nt have to keep setting it up.

The question was about image quality. The OP is on a budget, and sensibly rates image quality higher than convenience.

Actually a reversing ring or extension tube would be identical regarding quality as neither has any additional glass so the results would be down to the quality of the original lense. The extension tube is likely to give more reliable/consistent results due to convenience/auto exposure and as such overall you could argue would produce the better results .

What about a macro converter

I have a x2 macro converter that I use with a 50mm prime. You undoubltedly get a reduction in quality with these as there is a large amount of additional glass. I however do not possess a dedicated macro lense and find that the x2 convertoer gives me OK results as does my new Tamron 70-300 (even though only to 1:2). The advantage of my macro convertor is that it also is a x2 convertor.
The other option is a decent +4 filter - worth a try - what thread size do you have - I may have a spare knocking about that you could try.

At the moment i have 18-55 kit lens 52mm thread but i hope very shortly to upgrade to the 16-45 67mm thread i also have a 80-320 58mm thread.

It would nice to try something different.

thanks
