How to measure the magnification of a reversed lens?
F-number, magnification, and depth of field
How depth of field is related to magnification and f-number?
Changing the magnification while using a reversed 18-55mm kit lens
- Changing the focal length of the lens.
- By an internal focusing mechanism. This technique is used in dedicated macro lenses like 90mm, 100mm, etc. When you focus closer using these lenses, the length of the lens doesn’t change.
- A fundamental idea about depth of field, f-number, and magnification in high magnification macro photography.
- Enough information to set the camera settings (aperture settings at various magnifications).
- An idea about how to change the magnification when the lens is in reverse mount.
I assume that, with a reversed 18-55mm kit lens, you need to take photographs at different magnifications and they should be sharp and aesthetically good. The information that is given in this article will not really help you to get the desired result. There are some issues you face even after setting the right aperture for the magnification and everything. You would understand this if you experiment with your setup. Some of you might get it at first, but mostly the results would be less satisfying as you would mostly get improperly exposed, blurred, inappropriately framed images. So, in the next article, I will give you some tips to make better images. But, in the meantime, experiment with the setup and let me know your results.
