Got the same song/dance from Zeiss at the tail-end of conquest's production. They told me they "couldn't" install a #4 in a 4x32 or 2-8x32 because "weren't ever made with them."
"If that's the case, why am I holding in my hand print-outs from your website and vendors selling exactly that?"
"Well, um, we don't have the parts anymore because production is stopping."
This was 2010 or -11 IIRC. So it is, Zeiss must have their business reasons, but from a consumer standpoint we lost a terrific product that now also has no service? Zeiss should know this: when these scopes die, have zero interest in the Terra or HD5 offerings on their merits, let alone the C.S. experience. Doesn't make one giddy to shell out money on another diavari, either. Zeiss really crapped their own bed with this one.
