In the current digital imaging markets any significant improvement in sensor or display technologies (many of which are expected in near future) will almost immediately make the earlier models obsolete. Compared to "traditional" high-end optics, the potential profits should be made during very short product life-cycles, which IMO does not suit very well to a company like Zeiss.But as I have said earlier, a zooming objective is an interesting innovation, which - when well implemented - could bring some true advantages over traditional spotting scope design.Best regards,Ilkka</blockquote>
