Noctivid overdrive past infinity? (1 Viewer)

Noctivid vs Swarovski

I have Swaro EL of 2008 vintage, wonder if I should come back to Leica.

My last Leica was a mid-90's Trinovid and I always found very impressive optically. A little less bright than current models.

Is this a question about the Noctivid's focus, or the Noctivid vs Swarovski models in general or just a statement about the vintage Swarovski EL and mid-90's Trinovids?

So here is the official response:

Question: What's the value of Noctivid's focus past infinity overdrive? Has it been changed from Trinovid/Ultravid models?

Answer:

The Noctivid has the same specification of +/- 4 diopters. That being said, I’m told by the Technical Services Manager that there is additional adjustment available on the minus side when the user sets up their diopter correction on the unit, to at least about -5. This however would have the effect of taking away the minimum and some of the close distance focusing. He also warns that users with very high diopter strength requirements usually have astigmatism as well. Not correcting for that by using prescription eyewear typically leads to considerable eye strain after long periods of use.
