Scitex S-3 scanner lens set:
Scitex S-2 scanner lens set:
I have two complete sets of Scitex S-3 scanner lenses extracted a few months ago from two high-end Scitex 342L scanners. These scanners apparently used to cost $55,000 each when new. I want to sell one of the two sets. I also want to sell a complete set of Scitex S-2 scanner lenses which the original owner of the 342L scanners included as spare parts.
All these lenses come in sets of three, each optimized to copy a different film format onto an approx 35mm sensor. In each set there is a 110mm F/5.0 lens designed to copy 35mm film (m= 0.7/1.4), an 89mm f/5.0 (m=0.38/2.6) lens designed to copy medium-format film, and a 67mm f/4.9 (m=0.21/4.6) lens optimized to copy large-format film. FOV on sensor side is about 35mm for all these in the scanner orientation. Presumably (though not necessarily) each is optimized to fill the sensor with the short side of the film dimensions, and scan by moving in the direction of the longer dimension of the film. The magnifications I just gave assume this.
The apertures of all these lenses are f/4.9-f/5.0, which is a bit slow for good results on MFT format. They work very well at their designed magnifications on FF cameras. My favorite is the 110mm lens, which gives very nice results between at least 0.7x and 1.4x (contrary to the others, this needs to be used with its 39mm threads facing the sensor when m>1).
These are nearly apochromatic at their designed magnifications, but the 67mm in particular (and to a lesser degree the 89mm) shows a faint reddish halo around very bright white highlights on dark backgrounds. This can be minimized or eliminated by using DMap instead of PMax in Zerene. See my tests of my set of the S-3 lenses here:

The lenses have a 39mm thread at one end; there are no threads on the other end. A readily available 39-42mm adapter can be used to mount these on a 42mm or 52mm system. They are also easy to mount in reverse by constructing a "cocoon" of step-up and step-down rings around them (a 52-49mm step-down ring fights snugly around the lens).

Here is a compendium of other web pages I have been able to find about these lenses:

The opinions about these lenses range from excellent to not exceptional. I think it is important to use these lenses at their particular designed magnifications and orientations, and their quality suffers away from that. These are not symmetric lenses and their orientation matters very much.
This set is a nice way to cover a range of difficult magnifications on FF sensors. I would be cautious using them on smaller sensors because of their f/5.0 apertures.
The S-2 lenses look physically almost identical to the S-3 sets but the coatings are visibly different. I have not tested the for-sale S-3 and S-2 lenses because they are not in Ecuador with me. I could only test the set of S-3 lenses that I brought back to Ecuador where my test equipment is. In some internet tests an S-2 lens did better than an S-3 lens, but it is hard to know how different these really are from the S-3 lenses.
I'll sell the S-3 set for $700. I will sell the S-2 set for $650. Shipping charges are extra. [Edit: Items are in the US (my brother Larry who lives in the US will ship them to you).] I'll offer them here first, but if they don't sell, I will put them on eBay. I'm happy to accept returns from forum members, but will not allow that once they are on eBay.
