The Vixen VSD100 also is not as sharp as Tak, and shows again halation. I had the older Pentax version, and I can NOT recommend it, especially for modern CCD's. Seems fine for film, not so much digital.

Thanks Lewis. You are a font of information!
Very handy, thank you.
So the TS 107 F6.96 with the variable tube length adapters seems the way to go or stump up and wait for the CFF or go for another FSQ.
I love FSQs but want a little bit longer focal length as the 530mm native focal length is a tad short. 630mm may be more useful to me to get the look I am after in the images and a focal length I don't have covered at the moment.
