Hello everyone,

Do you have any info on the Panavision Primo Classic "soft effect" mode?

I know it is an optical, variable diffusion effect, but I have yet to see the effect on an image. Any links or screenshots?

This function is only available on the 24, 30, 65, 85 and 125mm, and I wonder if it cuts well with the other Primo lenses without the effect.

Best,

Hello Guillaume,

I would guess that the soft effect is a spherical aberration control. It would allow you to dial in the amount by which you can make the lens "less perfect." See the following:

Thanks Daniel,

Any pictures of the effect itself ? Can't find any on the internet.

Examples of the Tamron lens are a little easier to find. Here are a few links with samples:

The user Abbazz posted images on pages 1 and 3 of this thread: http://forum.mflense...ert-t40873.html among other lens examples (not all of which achieve softness by the same means). The same user posted additional examples here: http://www.pentaxfor...y-useful-3.html
