Hi, has anyone tried reverse lens macro? How is the one lens setup compared to the 2 lens in terms of image quality and usage? Thanks!!

There are ratios involved if you stack lenses.
at 50mm reversed, there is a certain magnification which I do not have the foggiest idea of. :sweat:
But with 2 lenses set, its the ratio of one vs the other. For e.g. a 50mm reversed stacked on a 200mm is 4:1. A pretty high magnification factor.
Reverse-Lens Macro Photography [tutorial] is a good simple writeup that's easy to understand.
2 lens combo (2LC) vs 1 lens reversed (1LR)
1. With 2LC, it is possible to get high magnification ratios >> 1:1 with a relatively cheap setup. The other way to get >> 1:1 is to use specialised lens like the Canon MPE 65.
For e.g., 50mm prime on 55-250 produces 5x magnification, theoretically.
2. With 2LC, vignetting is a very big problem. After stacking, it is almost impossible to get the whole frame usable. For e.g., after stacking 50mm on 250mm, the image area takes up like 20% or less of the whole frame. The rest of the surrounding area is black.
Using a bigger aperture prime (e.g. 50mm F1.2) apparently can help to reduce the vignetting.. but never try before.
So, technically, a teleconverter should also work with a reverse setup (1 lens) to get the extra magnification right?

Haha buying what? The reverse ring? I was using it some time ago, until I got a real macro lens. I even have the male to male coupler ring :bsmilie:
The 50mm on the body would be a better idea at least that's after my experimentation.
cool. and is that better because of the faster shutter speed in particular as compared to eh 18-55 lens?

kei1309 said:oh. gonna mount a 50mm on a 70-200mm :bsmilie:
but the minimum distance would be at least 1.2m away :bsmilie:
Hahaha how you find the male to male coupler? Stepping down cannot cos of serious vignetting :bsmilie:
