Je n'ai pas essayé les Vortex. Par contre, si tu parcoures les sites américains sur internet, ces télescopes semblent avoir une bonne réputation.
Vortex devrait bientôt commercialiser de nouveaux modèles Tactical dans la série Razor. Entre autres, le 5-20x50mm FFP, illuminé et fabriqué au Japon semble prometteur.
Voiçi un évaluation préliminaire effectuée par Ilya Hoshkin sur le site SWFA:
Update on upcoming Vortex tactical scopes: Vortex guys asked me to stop by again a couple of days into the show to talk about their upcoming line tactical scopes. It turned out that they planned to do more than just talk: they had two nearly-fully-done prototypes of the new Razor line of scopes to show me. The scopes I saw were: 5-20x50 with a 35mm tube and 1-4x24 with 30mm tube. Both scopes have FFP illuminated reticles and exposed knobs and are made in Japan. It certainly looked like a lot of thought went into their design, since I had comparatively little to pick on (and I assure you I can usually find something to pick on). The knobs had very nice feel to them. The glass looked good to the extent that I could tell. The reticles had interesting designs, that I think are very functional. In terms of user friendliness, every scope is an exercise in compromises: on one hand you want a streamlined appearance so that the various protrusions do not catch on stuff. On the other hand, you need those protrusions to be able to make adjustments easily and without looking if need be. I think these new Vortex scopes strike the right balance. Beyond that, there is really not much I can say about performance until I get to put them onto rifles and torture them a little. When these are ready for production I should be able to get my hands on them. The prices still need to be set, but it seems like they will undercut their competition by a non-trivial amount. Performance wise, I think these will go after IOR and Nightforce above all else, and I would not be surprised if they take some sales from the really expensive scopes like Zeiss/Hensoldt, Premier and S&B. The first version of the 5-20x50 will have MOA reticle and MOA knobs. Mil/mil version will follow. Further out, there will be other models in the Razor line to fill other niches.
