Reverse lens macro setup

[rjpierrard]

<p>Hi,</p>

<p>I've been looking at a lot of macro setups, especially the bellows and reverse ring, and I'm wondering, first, if there are any major considerations I should look into before committing to anything in this area.</p>

<p>The other thing I'm wondering is that given that you can make a macro setup with a reverse ring, what happens if you put together three different lenses with reverse rings, or a wide angle lens Before the longer lens, etc?</p>

<p>Thanks for your help!</p>

<p>edit: I'm also wondering about vignetting - for example if you use a 77mm lens with a reversed 52mm lens, will you get cropped edges?</p>

<p>A reversed wide angle in front of a longer focal length lens can work quite well, with little likelihood of vignetting. Set both lenses at infinity and focus by moving the camera/lenses for the sharpest image. The aperture (entrance pupil) is best controlled by the front, short FL lens. Stacking more than a pair of lenses will probably create more headaches than it is worth, but you might wish to try it.</p>
