Schneider filter IIIb for SS 100XL

[Fermat]

Hi everyone,
The Schneider IIIb filter is also recommended for the Super Symmar 110XL.
I had always intended it to be useful for pushed wide angles (58XL etc.).

I was wondering if it actually made a difference on the SS110XL or if you can do without it.

Ciao

What format film are you using? I never found a need for a center filter with 4x5 film, but when I used the 100 SSXL on 4x10 it was very necessary.

There are several discussions on the forum about Schneider's Super-Symmar XL lenses and light falloff. There's a view that there is a design tradeoff with these lenses that makes a centre filter particularly advisable, including when used with negative film. Worth reading.

I just purchased a copy of the XL 150mm and decided to get the centre filter. On 8x10, the 150 is around 21mm to 24mm in full frame 35mm terms. Focused on infinity at f/22, it has an angle of view of 105°.

That said, forum member Mat Marrash uses the XL 150mm without a centre filter with his 8x10 camera and black and white negative film. He uses the lens in a number of his YouTube videos and the videos show the resulting photographs. Might be worth watching the videos, and/or looking at the photographs on his website, and asking him what he's doing in processing, if anything, to address falloff.

Here are three of Marrash's videos where the XL 150 was used:

I use the ssxl 110mm with 4x5 and I don’t feel the need of the center filter unless you use extreme rise/fall/shift.
