Last week I bought an EOS 6 and made some pictures
1. Western sky (moderately light polluted), single frame Samyang 14mm f/2.8 squeezed to f/4, 15 sec 6400 ASA.
2. Orion with EF 50mm f/2.5 compact macro squeezed to f/3.5, 4 seconds, 30 frames (+5 flats) at 6400 ASA.
The real test will be next month when I go to real dark skies in South Africa.
Full-spectrum modifying it is too many risks for me as I lose all the WB settings and get stuck to custom WB, AF, etc.
Clip-in filters for Fullframe are now offered by
Astronomik where the CLS costs $159, but these filters force the mirror always popped up as long the filter is built in. This might damage the mirror popup mechanism as I guess.
So the only alternative I want to buy a 2" (48mm filter thread)
Astronomik CLS filter (also $159) to be used in front of 50mm f/2.5 or 85mm f/1,8 (squeezed to f/3.5) lenses or in the 2" barrel on which the 6d is mounted to the Genesis.
The idea is setting the white balance to a custom value based on a white surface photographed with the CLS filter.
Does somebody have experience with such filters or experience with a modded 6d ?
