Schneider-Kreuznach APO-DIGITAR 43mm XL need for center filter?

I never used the 43xl with the 3100, but I did use the 60xl with that back frequently. I think you will want the CF, but maybe “need” is too strong of a statement. It depends on what you shoot. I also used the 35xl with that back. I would say the CF was necessary with that combination.
I think you will need it for significant movement, but shooting straight with little or no movements should be ok as long as you always combine it with an LCC.

Not necessary with achromatic, LCC is sufficient. You can also get the Rodenstock CF which gets you half way there.

Which Rodenstock centre filter may this be please, Paul?
Shifting or not? Was just out with 43, CF, and 3100. Shooting straight on, agree with the above, no CF really needed. LCC does the trick. So does CF without LCC. However, shifting (say 15mm) is another story. Normally with a CF and LCC it should work, but oddly, had a fail this past weekend. Likely user error in the LCC exposure... As Paul says, with Achromatic, you are likely OK.

Yes, it is that one. The gradation is different from the real CF filter so it is not a perfect solution. But it helps a bit with LCC. Given how easy they are to find it is a good second best solution.
By extension, the 28 XL is also amazing for that reason on an achromatic back. You just do a clean LCC exposing for a histogram which is correctly exposed and you can get perfect shots.

On the gradation - it can create a problem in very uniform skies when the gradation is not perfectly adapted to the lens; then you have a situation where the gradation overlaps in a not ideal way with the natural light fall-off and so you have a brighter area after a darker area all of a sudden. It usually is not a problem though, but clearly the real CF will have the correct gradation.
This said, it still helps with LCC and overall image quality as it still minimizes the total delta between darks and brights in the image.

The 43 XL is the closest you can get to a single-lens all-in-one architectural solution. It covers so much ground and doesn't need distortion correction which is a godsend in post if you don't own an XT.
Such a shame SK went out of business after 15 million lenses! There are maybe a few hundred in existence of these and SK produced millions and millions of lenses before that. Crazy to see all of this in this perspective.

I agree, such a shame! They made these insanely great lenses in very few numbers (43XL, 60XL and 120 Aspheric) and then shut down. I'm glad I got my 60Xl and 120 Asph. in time.

Paul, so you can get away with not using CF, just LCC?

Thank you
Got them way back in 2014.

Hey Peter,
You'll likely run into sensor tiling with the 43XL and shifts. There is a way to fix it though…

How to Fix Sensor Tiling With Photoshop
My first choice for photo editing is ACR/Photoshop. While looking for a way to apply LCC corrections without using C1/Phocus/Lightroom I ran across this article: https://pduncan.com/2015/11/20/vignetting-4/ The steps outlined in the article do a good job of fixing vignetting, but didn't really...

Yes, if you don’t do extreme shifts!

Just one thing to add to Diggles; to be fair, sensor tiling occurs only when you do extreme shifts. I would need to check when exactly it happens in terms of mm on a full-frame MFD sensor, but in practice, it is not that of an issue, at least for me. I'd say 15mm and more without issue if the sensor is in horizontal orientation, but would need to check.

How much movement qualifies as extreme?
