LOL! I think Vespobuteo explains this well.

I`m not really looking for a new scope purchase right now, but I`m trying to square £3.5k for a 95mm objective that shrinks to below 60mm at low power.

Its a balance of capabilities John and which may not meet your personal needs.

At 2.5mm the EP is similar in size to your pupil in normal daylight and its no coincidence that at this size the human eye is at its most effective with regard to detail. And as Vespo pointed out in normal daylight your pupils will be this size no matter what scope you are using. If you need a scope for late evening this may not be the scope for you.

That`s very true but how many of us use this proposal to choose a binocular with a 2.5mm exit pupil for our Birding needs ?, 8x20 sf anyone ?

Also true but binos don't offer the zoom of a scope and the full 95mm is available from 40x mag upwards. Meanwhile at lower magnifications there is a super-wide field of view.

And scope users are used to small exit pupils of 1.5mm or less at high magnifications. Its a balance of capabilities and clearly this balance doesn't appeal to you. I hope to borrow a test unit from Zeiss soon so I will be able to find out if it appeals to me or not.

Lee,

I would`nt say the balance of capabilities doesn`t appeal to me, its clearly an interesting design, and I only have a first impression to go on, Ohweh has just posted a comparative review and clearly enjoyed the Zeiss more with greater familiarity.

I myself am used to a very small ep on my ats65 at 60x, but I use my scope far more at 20-30x and however good the Zeiss is at high power, not getting the full benefit of that huge objective at 23x would definitely annoy me.

John.

I can certainly understand that especially if you bird a lot in the evenings.

I’ve drawn a line chart depicting the relation of mag. and aperture.

Hopefully "range" will come along to answer, but I notice that his chart appears to track the points from this post by Kimmo Absetz.

Thanks Henry!

One remark: full 95mm are not really possible. The screw-in size for lens hood/filter is 95mm, so the effective diameter of the front lens must be minimal smaller.

For me, this is an advantage, see my review.
