What's the bug?and what happens when you shoot LCC plate and you find out that there's a bug in capture one with your particular back and LCC options... ;-(
I suggest you create a thread on the Phase One users website. You'll get a meaningful answer straight up.Probably should create new thread if you have an issue.
Doug:Sorry I missed the party but thomas has it all right.
Advantages of not using a CF:
- no loss of light
- no loss of optical quality (no additional glass)
- slightly lighter rig
Doug Peterson
The loss of quality is largely theoretical. In the real world, you will see no difference, unless you allow the two additional lens-to-air surfaces to get dirty.Doug:
Can you show the loss of quality when using a center filter? I am interested in seeing the impact.
My Alpa mount Schneider 35 XL Apo-Digitar is 52mm and takes the IIf. The Apo-Switar variant from Alpa (same optics) has the 72mm filter thread and requires a IIa filter.Not sure I've ever seen a 35mm XL A/D with a 67mm front thread - maybe an Alpa variant or similar?
To me the real issue of whether to use a CF or not is if you want to give up 2 stops or so of your sensors dynamic range.I happen to have the CF for this lens listed in the B&S at the moment -- as new for $200 shipped US. FWIW, it is the 2*G* that is correct for the 35 XL APO Digitar. As has been said, advantages are it eases the load on C1 for the LCC and most especially, eliminates the excess noise at the edges from said lifting. I have never noticed any loss of image quality from using one, though I suppose it's there in some minor form.

Actually, you will be giving up 2 stops of exposure, but increasing the dynamic range available to the LCC software as it has to do less work to correct brightness falloff. It will be primarily using up DR to adjust colour cast not density. This is why corrected files show less noise at the edges when the starting point is a file that was shot with a centre filter.To me the real issue of whether to use a CF or not is if you want to give up 2 stops or so of your sensors dynamic range.
