A few additional observations . . .
Eye Relief
The nominal ER of the 7x42 is 14 mm, which seems accurate. It’s more than adequate for those who don’t wear spectacles but may be a deal breaker for those who do
So as usual, if you do wear glasses: if at all possible try before you buy *
Eyecups & Handling
With the eyecups, the combination of the small diameter and short extended length, means that they often ‘float’ in front of the eyes, making positioning difficult
This is a problem for most with the smaller leatherette ones (33 mm diameter), and for some with the larger RA ones (39 mm)
However, while the RA eyecups are similar in diameter to those on many x42 roof prism models, they lack the broad rounded edges typical on roof prism eyecups
Regardless of the model, my personal preference with all the Habichts is to use the hold I’ve previously described in detail in posts #6 and 7

It’s:
- more comfortable, as there is increased contact between the eyecups/ fingers and the face
- more consistent in positioning, as it provides 3 point contact (both index fingers and the rear thumb)
- more stable, as it provides a more secure ‘weld’ of the binocular to the face, and
- compatible with my preferred focusing technique described in the posts
* Second-hand Choices
Habichts are not routinely stocked by Swarovski dealers, so it may not be possible to try before buying
However, there are also second-hand options as I’ve outlined previously in posts #1 and 2 at:

And due to Swarovski’s numbering practices you can accurately date a model and it’s features
Enhanced Stereo Effect
An unmentioned general advantage of Porros prism binoculars over roof prism ones, is the enhanced 3D image at close to medium distance - out to at least 50 m -
due to the significantly greater spacing of the objectives
In this regard, the view through my 7x42 Habicht is more pleasing than that of either my Leica Ultravid HD or my Zeiss Victory FL
