Could holding my camera lenses backwards ("free-lensing") for macro photography cause damage?

Whenever you're freelensing (holding the lens against the camera, rather than securing mounting it), you do run the danger of getting stuff inside the camera body (including stray light), but as long ...

Mounting a lens in reverse: strength of the filter thread part?

Lens weight when reverse mounting is rarely an issue. The technique gives the best result with normal or slightly wide angle prime lens. These are not heavy. Mounting a telephoto lens in fact gives ...

Could holding my camera lenses backwards ("free-lensing") for macro photography cause damage?

As far as I know, the only potential for damage is through hitting something with the exposed end of the lens, or with things ending up inside the lens. So long as you aren't shooting in wet or dusty ...

How does a 'reversing adapter with automatic system' deal with the *inverseness* of the reversed lens?

The aperture operates in a plane perpendicular to the optical axis of the lens, so reversing the lens doesn't affect the way the aperture operates. Opening the aperture still lets in more light. ...

I free lens quite regularly. I also have extension tubes that I ... free lens with as well. This photo I had extension tubes on without the end piece that I then slid an old projector lens into. Not ...

Could holding my camera lenses backwards ("free-lensing") for macro photography cause damage?

It isn't inherently dangerous for your lens, but some camera bodies have their lens mount sticking out a bit. If the front element of your lens is wider than the body mount, then just be careful not ...

Why is my reversal ring not working with the lens's aperture?

There is no electronic connection between the lens and the body. Except if you have bought the macro adapter. If you want to control the aperture, you have two options: Buy an adapter that provides ...

Why does changing aperture change field of view in my reverse-lens macro setup?

It's mechanical vignetting. The aperture of the rear lens should be wide open and you adjust the aperture of the front lens. See here for more: http://www.coinimaging.com/coupled_lenses.html

What will cause a washed out spot in the centre of an image?

Looks like classic "blue spot" where flat (or near flat) optical surfaces are reflecting light back onto the sensor which was reflected from the sensor itself. It's pretty extreme which may be due to ...

Mounting a lens in reverse: strength of the filter thread part?

I have never trusted a reverse mount for macro photography. Partly because of your noted concerns regarding the stress on the screw-thread [& possibly worse on the zoom, should you try to use one],...

What do I need for reversed-lens macro photography with an entry-level Nikon DSLR?

Wide angle legacy lenses are typically used when reverse mounted on a camera body. Your best bet is to use a "legacy" adapter that allows mounting old, non auto focus lenses to your digital camera ...

How does a 'reversing adapter with automatic system' deal with the *inverseness* of the reversed lens?

I would hazard a guess and say probably the same way it does normally. As the AF is in body, and the adapter provides communication between camera and the lens it keeps sending signals to the lens ...

Is lens stacking/reversing correction possible?

In short, no to all questions. Aside from manufacturer-provided utilities (in-camera or otherwise), there is no magic formula for correcting lens abberations in post, nor is there a straightforward ...
