I apologize if this has been addressed already (I've searched here and elsewhere but had no luck). I shoot a Speed handheld in New York City, where the considrable security guard population seems to think tripods are illegal (like any good New Yorker, I don't mind a vehement argument, but I'd rather take pictures). My 135 Optar is well suited to this close environment, but recent hikes in the Grand Canyon made clear the usefulness of something in the 90mm range. My question is whether there is an auxiliary viewfinder that would approximate the view through a lens of about this length. I wouldn't want to haul a tripod around when hiking either, so ground-glass viewing is out. I understand there are finder masks to be used with longer lenses, but I suspect there's no wide-angle glass that can be similary affixed to the stock finder when shorter lenses are used--which probably wouldn't work with the parallax adjustment anyway. I can rig a wire piece to clip onto the sports finder, but I was hoping Graphlex had come up with something more elegant, since they seem to have thought of everything. Thank you in advance for any suggestions.
