Enlarger Lens with Illuminated Aperture for Camera Scanning

[punkzter]

I'm putting together a negative scanning setup and have found a nice 80mm Rodenstock Rodagon f/4.0 enlarger lens that I'm thinking about purchasing.

I'm using a light pad to illuminate the negative. I have a Simmons Omega enlarger with the copy stand attachment. I have a Sony A5000 attached to it.

My overly paranoid question is, should I be looking for an enlarger lens that doesn't have an illuminated aperture? If I'm not working in a perfectly dark environment, can light leak through the aperture ring and up through the red dot to the camera sensor? Does that make sense?

I know that I can just tape or paint the dot, but I guess I'd rather just get what works.

Illuminated aperture lenses are usually the most up to date optical formulae - a piece of tape over the top of the light pipe will do the job just fine.

Okay. Yeah, so just get over my distaste for taping things and do it

Thanks!
