Eumig Mark 610D Vs the Lux version?

[Stuart Budd]

Afternoon, still working on the Mark S 710D but do have a question regarding the differences between the 610D and the Lux version. Is it just the lens?

[Stuart Budd]

From the manual:

The MARK 610D LUX is designed for those who require the
utmost optical performance and light output in a movie projector.
The high class exceptionally fast f/1.2 "Supmgon" zoom lens
with its 12.5- 25 mm focal length range plus the ideal design of the lighting
system yields about 35% more light flux on a 44% larger screen area than
models with the standard 15 - 30 mm f/1.3 lens at the same projection
distance.

Forum member Erik Snel made that interesting video about the 610 D : A tribute to the Eumig Mark 610D Dual gauge 8mm projector - YouTube

It's an interesting well made video on the 610.

Yes, just a faster lens is all there is to a Eumig machine with "lux" in the listing. Any Eumig machine can become a "lux" machine by simply changing out the slower lens for a faster one. There is nothing different or special in the optical path on any of the Eumig machines marked as "lux". The only difference was a faster lens and a higher price tag.

But at the same time, a faster lens is not always the best option, especially today with most film being more than 40+ years old. Any slight warpage of the film will become more and more apparent when the speed of the lens is increased, which means you start to notice severe edge focusing problems, which tend to hide using normal slower lenses. The faster the lens, the more critical focusing becomes. Or at least that has been my experience.

Good observation there with the focus and other film related issues. My 710D has a 1.3/15-30. I could compare with thr 610 Lux lens, Eumig Suprogon Zoom Multicoated 1.2/12.5-25. This lens is twice the price of the 1.3. There's no aperture contol on these lenses so your, as you say, stuck with the full opening.
I doubt there'll be much if any difference but we'll see.

Focusing issues aside,the Suprogon is a much nicer lens than the f1.3, and well worth the extra cost.
