Roger has just added 2 new reviews, which will be of interest to many:
A) The now classic Leica 7x42 Ultravid HD Plus at: http://www.scopeviews.co.uk/Leica7x42HD.htm *
In terms of the optical construction, see the attached diagram that clearly shows the eyepiece has 4 lenses in a 1, 2, 1, configuration
B) Zeiss SF 8x42 at: http://www.scopeviews.co.uk/ZeissVictory8x42SF.htm
Usefully at the end of the review, Roger includes direct comparison with the Swarovski NL 8x42
And just one clarification, the image labelled ’Complex SF eyepiece design’ shows the newer x32 version, which has an eyepiece of 6 groups
- verses the 4 groups of the x42 version, shown previously in the review

* As Andreas correctly points out below, the test is actually of the HD, not the HD Plus
The primary difference is that the Plus has Schott HT glass prisms, see a screen grab from a 2015 catalogue when it was introduced
