Thread: Reverse lens macro

  1. #1

    Default Reverse lens macro

    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.

    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.

    oh... so that how it works. I wanted to make sure i know how it works before i get the rings, thank!!

    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.

    Thanks!! It's really helpful and it seems that vignetting is indeed a serious issue when he use a 2 lens combo

    So, technically, a teleconverter should also work with a reverse setup (1 lens) to get the extra magnification right?

    Could be. Never try b4.. but theory sounds workable..

    A 1LR probably can't go much beyond 1:1.. add a 2X an maybe can get 2:1.

    There's 1 sample of 2LC..

    "MONETARY AUTHORITY OF SINGAPORE" can be seen clearly.

    hi all,

    didn't really want to clutter the forum with a new thread so i thought i'd post here!

    i have two lenses canon lenses (18-55mm kit lens and the 50mm 1.8f II lens).

    i'm wondering what combination will yield best results especially for handheld macro shooting?

    i'm asking as i'm deciding if i shld buy
    1. 58mm reverse ring for the only the 18-55mm kit lens OR
    2. 52mm reverse ring for the 50mm lens OR
    3. 52-58mm reverse ring to stack the kit lens AND the 50mm lens.

    Also, if i were to stack the lens, should the 50mm be on the body or the 18-55mm kit lens? my thought is the the 18-55mm being attached on the body will be able to offer its IS capabilities while on the other hand, the 50mm attached to the body will give a wider aperture setting for faster shutter speed.

    Lastly, how do you guys manually control the apertures for canon lenses that does not have the lever (or is there not a need to do so?)?

    Advise much appreciated!

    Hearing such a complicated setup makes me wanna go for a dedicated macro lens... At least I won't have a "long" lens problem to worry.

    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

    The 50mm on the body would be a better idea at least that's after my experimentation.

    For the aperture for canon lenses, just set the aperture you want, press down the dof preview button and detach the lens. The aperture should be fixed at the aperture you set it at

    cool. and is that better because of the faster shutter speed in particular as compared to eh 18-55 lens?

    With flash it doesn't really matter, you can set at pretty fast shutter speeds. And you want to stop down to get everything in focus, shooting wide open won't get you good results

    i understand now. thanks. just bought the 52mm ring for the 50mm lens. can't wait for it to arrive.

    oh. gonna mount a 50mm on a 70-200mm

    but the minimum distance would be at least 1.2m away

    Hahaha how you find the male to male coupler? Stepping down cannot cos of serious vignetting

    LOL that will require some technique.

    There was a post on the magnification with prime lens used for reverse lens macro (see post#19) in link. Also show the reverse lens macro work of a senior member "longko"
