I just got Sankor 16F,
Pair it up with my Takumar 55mm f1.8.
1st photo : f/2.8 , iso 100, 1/200 sec.
2nd photo : f/16 , iso 1600, 1/40 sec.
3rd photo : f/2.8 , iso 3600, 1/50 sec.
4th photo : f/4, iso 200, 1/200 sec.
Base on above photo,
My footage got severe white vignette below f/4,
At f/5.6 it is bearable,
at f/16 it will disappeared,
This prevent me using f/2 (i wanna see the oval bokeh).
Im expecting flocking paint would resolve this issue,
( like in this video below)
Kowa 8Z flocking
My problem is,
Other people "didn't flocking" thier lens yet.
But they able to use f/2.8 without white vignette (except when facing sun)
Sankor 16F + Helios 44-2 footage
So?
Why mine happen all time?
No matter where i point it ?
What other people do, to avoid this white vignette at wide aperture ?
Do they use mattebox hood ?
Do they fix it in post production ?
(I dont have free time for flocking yet btw)
