28/2.8 and vigneting with filter and hood

Mike,

I have had the same problem with my D28/2.8

Aria has 95% viewfinder so you cannot see vignetting. Moreover viewfinder has its own vignetting.

So, you should make some photos of white paper, for ex&le. Try it with different apertures, especially wide open. Then inspect film with loupe.

Regards,
Yuri
 
Mike,

Do I understand you vignette with the recommended hoods? According to Contax, these are the 55mm G-12 (rubber) and the No.1 (metal).

As Yuri says, the Aria has less than full-frame coverage in the VF: you need the RTS III for 100%. The direct-view method is further h&ered by the D28/2.8 wide open, when light fall-off reaches 80%.
 
Yuri,
Thanks. You are obviously correct. I had neglected to consider the limitations of the viewfinder. I will make some trial exposures.

Rico,
Unfortunately I do not have the recommended hoods. Thus my experiments with other available equipment. By the way, where did you obtain the information that light fall-off reaches 80% with the D28/2.8 wide open?

Thanks for your imput.

Mike.
