Que penser des longues-vues Kowa avec un objectif de 88 mm ?

The new Kowa Prominar 88mm Spotting Scopes (881, 883 and 884) are certainly among the best spotting scopes on the market, due notably to their large 88mm Pure Fluorite objective lens, which ensures maximum light gathering, clear visual range, sharp and contrasting images with a very low chromatic aberration.
The qualities of these new scopes are numerous : lenses made of environment friendly Eco-glass, use of magnesium which increases durability while reducing weight, an inner focus system which decreases image movement when focusing, the bility to focus from 5 m to in two revolutions of the quick focus knob, an eyepiece locking mechanism which prevents the eyepiece from falling out or being lost, …
And the digiscoping resultats are very good, even if few birders have already published photographs on the Web. But all these outstanding features have a price, and the 88 mm Kowa scopes are very expensive. Do they really worth it ?
