So I happen to have my 18-55 lens, a 70-300 lens and the probably, potentially reversed lens which is a 50mm F1.8.

Have any of you used a reversed-lens-on-a-lens setup before? I'd like to know what my options are...

thanks[thumbup]

I think that for all the hassle you'd go through with the lack of AF and other inconveniences of using a revsersed lens macro setup, you could simply buy a set of Kenko extension tubes to give you very good macro capabilities on a lens like your 50mm.

This link shows just what you could do with the set of tubes. They contain no glass, so image quality is retained, as is AF. I'd say they do a very good job of creating a makeshift macro lens, especially for the price.

*note* I didn't take the photos that come together to form this example.

are you sure that combining lenses does not preserve the ability to AF?
the lens that's normally attached to the camera should AF normally isn't it? it's just the extra reversed lens that won't have the ability to AF, which I doubt if needed.

I also like the combined setup's AOV more... I mean, after all I also have a 70-300 with macro ability, which does what these kenko tubes do, and really darn good.

I've done it loads of times, well worth trying. Perfectly fine to use extension tubes instead but surely it's worth experimenting with this first as it won't cost you a penny and it really isn't very difficult to focus at all. First make sure your reversed lens is set to its largest aperture (so f/1.8 for most 50mm lenses) then move yourself forward slowly until the image is in focus, compose the shot and finally select an aperture for your desired depth of field. It's usually better to go for f/8 and up as it's very easy to get things out of focus when you're working with such a shallow depth of field.

Ideally use a tripod, although it is possible without if you're patient and are photographing in good light.

but how do I connect two lenses together? let's say the 18-55 as the main lens, and the 50mm reversed?

Improvise. I used electricians tape, as long as they're lined up properly it'll work fine.

And now...... The results![thumbup]
used some tape... [rofl]

As you might see, the lens barrel is visible at the corners. I think that using longer focal lengths on the main lens(not the reversed one) should fix this issue, my guess is somewhere over ~70mm...
For now this result is more than fair, as I can crop these to death, and still preserve IQ.
Btw.. I used the kit lens(main) @ 55mm and 50mm F1.8(reversed).

Zip file that contains all the pics(FULL RES 10MP) uploaded: http://files-upload.com/331578/IMG_2572.zip.html

Hope some more of you try this too and post some shots...


EDIT: DAMN IT. ImageShack resized em down!!! I uploaded the pics as 10MP so you'd notice the detail and sharpness.
I will zip em all up and upload somewhere you all could download it.

Not too shabby for a first outing with this sort of setup. You can buy adapter rings that make reverse mounting super easy, but with that sort of setup it is possible for you to strip or otherwise ruin the filter threads on either or both lenses, so be careful with that sort of thing. That said, the 50mm f/1.8 isn't much of a heavy lens, so you should be fine.

BTW - here is a guide for other people looking to do this as well..
