Clip filter for Canon EOS full-frame cameras 5D MKII, 5D MKIII and 6D
The clip filter can be mounted without tools: as the name suggests, it simply clicks into place on the camera body. It can also be removed without tools. No modification to the body is required to use the clip filters.
Please note that the XL Clip Filters do not work with the Canon 5DS, 5DSR, 5D Mk IV and 6D MKII! The 5D MkI only works without LiveView.
The ProPlanet IR 807 is intended as a supplement to the ProPlanet IR 742, for very poor seeing conditions and telescopes with sufficient light gathering power.
Mode of operation: The ProPlanet IR 807 filter cuts off the visible part of the spectrum and only opens at a wavelength of 807 nm. This blocks the areas of light that are particularly sensitive to seeing and allows the areas of longer wavelength light that are significantly less sensitive to seeing to pass through. This approach visibly reduces seeing problems in planetary and lunar photography without significantly reducing the sensitivity of the imaging sensor.
The loss of sensitivity in most cameras with the IR 807 compared to the IR 742 is about one f-stop, corresponding to 50%, or, conversely, a doubling of the exposure time. The one-millimetre-thick filter is homofocal with all other Astronomik filters.
The filter is not sensitive to moisture, does not age and is scratch-resistant. It comes in durable packaging.
Please note: In principle, all camera lenses can be used with the Clip-Filter - i.e. Canon EF lenses or camera lenses from other third party manufacturers such as Sigma, Tamron, Tokina, Walimex etc. However, the use of clip-filters with Canon EF-S lenses is NOT possible!
Our expert comment:
The filters fit Canon full-frame cameras. Operation is only possible with the mirrors fully raised. 5D MK II, 5D MKIII and 6D can be focused easily using Live View. The 5D MKI only works without Live View. The 6D MkII, 5DS, 5DSR and 5D Mk IV models do not work.
The mounted XL clip filter fixes the swing mirror in the upper position. The optical finder cannot be used while an XL clip filter is mounted. Focusing, searching for and centring objects can only be done via the Live View monitor on the back of the body or via the camera's remote control using a USB cable. All functions such as autofocus and image stabilisation remain available.
