CineLens SPHERICAL Z3155 Macro SET is a collection of lens objects that use verified real-world data from VFX.
These can attach to any CineCamera in Unreal.
These contain basic lens models, including iris and distance mapping to lens pulls as well as dynamic distortion mapped to focus distance.
Macro lenses have very little distortion, but are able to focus much closer to camera.
The majority of the distance throw is for near focus work, which gives a lot more precision compared to normal lenses of same focal length.
Vignette has NOT yet been implemented, though possible at a future date.

The result reacts more like a real world lens.
As you get to the upper limits of distance, it falls off exponentially, as you’d expect.
In a physical lens, when focus is pulled, the glass moves thru the housing.
You can see this reflected in the distortion and the vignette of a wide lens as it’s pulled:

Longer lenses also show this, though more the effect is more subtle.

This helps give the lenses a sense of “life” that mimics its real world counterpart.
Some lenses only require a handful of maps, while many others can require over 40+.

Z3155 Macro SET of 2x lenses :
(Names greeked to balance copyright concerns with need to reference specific physical data.)
- 050mm Z3155_CP2_Macro (sensor: 36.7mm x 25.54mm) focus ring diam.: 134mm
- 100mm ARR1Z3155_M4st3r_Macro (sensor: 23.7mm x 17.82mm) focus ring diam.: 114mm
Created from VFX production grid shots, solved in 3DE converted to raw distortion values.
Raw values should give much better performance than STmaps.
Also saves over 5GB worth of 32-bit EXRs for this set.
