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!!
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.
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.

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!

hmm interesting... Calvin when are you getting it... darn this BBB virus
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.
i understand now. thanks. just bought the 52mm ring for the 50mm lens. can't wait for it to arrive.
