Excellent question - I apologize for my comment - I presumed that the Merlin WAS a synthetic because every Steiner I have examined had a "plastic" housing - and several folks I knew that owned them were disappointed after a few years. Apparently the Merlin line is a metal alloy.Did not know that. I take it you are saying that Steiner and Zeiss Conquest have plastic housings?
Who cares if the Zeiss are plastic - they come with a lifetime transferable warranty. I would take better glass and coatings long before basing my decision on the casing material.
I have had a pair of Steiner 7x50 Commanders for about 25 years, the original milspec ones, fabulous glasses, exceptional in low light and tough as nails. Don't have any experience with the later commercial models though![]()
I have a set of 8 x 30 steiners I think. t5hey are excellent value and really tough!
