    • Large lenses for completely vignetting-free exposures up to f / 3.5. Maximum sharpness over the entire image field
    • Phantom Coating™ Group multicoated for maximum transmission and total freedom from reflections
    • Next to the photographic only version, there is also a visual version that contains all parts of the base elements as well as additional adapters for visual application:
      • 2458400A: Photographic Version with removable 2" Stoppring, usable either with T-2 (M42x0.75) or M48x0.75 connection
      • 2458403: Visual Version (V-1 Set) contains all parts of the photographic Version MPCC Mark III #2458400A as well as 1¼" to T-2 focusing eyepiece clamp (#2458125) and adjustable VariLock T-2 extension tube 20 – 29 mm (#2956929)

    Please note: This set replaces the former set #2458402 for visual and photographic application of the MPCC Mark III. The old set consisted of a multitude of rings – but was not adjustable in optical length such as this V-1 set.

    The idea for this new and much more versatile set was born after we received this detailed question regarding eyepiece adaptation on MPCC, where we recommended our VariLock and focusing eyepiece clamp as best accessories.
