@CameraQuest and other knowledgeable folk: is the optical formula of the conical version of the Heliar 50mm f3.5 Vintage Line the same as the older limited edition collapsible nickel lens of the same name? I used to have the collapsible version, a beautiful lens, but I didn't use it much because it was f3.5, and the collapsible design and infinity lock bugged me a bit. But the Vintage Line version solves the design factors, and I did enjoy its very rounded, organic rendering.
