A nice new lens from Schneider. for those qho can't decide between a 35 and a 47mm?

Oh, and if i get this right, The "centerfilter" is a software plugin

Well it would have been nice to see some more infos. For example MTF and distortion. Oh a price would have been nice as well.

So how does this work, doesn't it mean you would have to take note of any movements made for each shot? Without know which part of the image circle was captured, how could you correct it.
BTW here's an English translation http://www.pressebox.com/pressemeldungen/j...xid-311499.html (http://www.pressebox.com/pressemeldungen/jos-schneider-optische-werke-gmbh/boxid-311499.html)

yes, either note it or shoot a white plate after each shot/series with the same settings. The Plugin is actually a bit useless as you can correct color cast and light falloff based on a white plate shot on layers in Photoshop quite easy. If you use a raw software that provides these correction tools (actually all MF softwares do) you don't need a plugin like that at all.
I wonder if the 43XL will replace the 47XL?
-
Sounds like a really great lens and can not wait to see images shot with it, likewise with the new 28 as well. Now they just need to upgrade their 35 mm.
If anyone has any images taken with this, would really appreciate seeing them.
-

The Schneider Apo-Digitar 35XL is one hell of a great lens, very high resolution, allmost no distortion, good image circle @ 90mm, so please elaborate what needs to be upgrated.

Huh, I tested that Schneider 35 and only found it to be marginally better than the Rodie Apo-S Digi. Both showing softness at about 8mm of shift on a P45+.
Have you gotten better out of yours?

I did not mean it like that, yes it is a damn good lens from what I have seen. It is just that they are rethinking their 28 mm and 43 mm in response to Rodenstock's HR series. I would expect that they are looking at their 35 mm as well just to keep innovation going and continuing to progress, what we would expect any good company to do.
I was just thinking out loud about how they could make better an already good lens and did not do a good job communicating that.
-
Also, every company, no matter what kind of business, always needs to keep innovation moving forward no matter how much better of a product they think they have or they are doomed to fall. Happens a lot and being that I prefer symmetrical focus lenses over retrofocal lenses, I would not want to see that happen to Schneider.

Yes, much better, but then I'm using a plate camera and not a rail camera.

I understand performing this correction in Capture One, for example, but you seem to imply that with a 'white plate' correction file and Photoshop
layers one could bypass the raw converter.
How would one do this? I ask because I've just picked up a Leica M8 and am suffering with a combination of magenta/green variance across the frame with
wide lenses and no combination of Leica coding/correction solves the problem.
If there was a process,outside of the raw converter, where I could take a white plate exposure and apply it to the M8 file then I would
be grateful.
Thx,

Shoot a white plexi plate (see: "lens cast calibration") with the same aperture and focussing as the actual image.
- Process capture as a TIF
- Process LCC shot with the same settings (white balance, icc profile) as a TIF.
To correct color shift:
- Open the capture in Photoshop
- Add a second layer, mode overlay, select "fill with 50% grey", set layer back to mode "normal"
- Add the LCC shot on a third layer, set layer to mode "color"
- Merge 2nd and 3rd layer on a fourth layer, invert, set to overlay
- Delete (or turn off) layer 2+3
-
Much appreciated tho_mas.
Will give that a try tomorrow to see if it sorts out some color cast on the M8

I received this from Schneider without any note about nondisclosure.
So I think it's okay to make it available here:
[attachment=18780:TD_AP_56...450_1CID.PDF]
[attachment=18781:TD_AP_56...450_2CID.PDF]
Price: €2178,-

Thanks for the PDF !
any news about the 28 ?
-
Is the new 43mm retro focus?
-

not that I know of. It's actually a revision of or an addition to the 47XL to improve corner sharpness and light falloff (still in 110mm image circle!).... at least that's what I was told.

Thanks very much for sharing this. Studying the data sheets, it seems that the new 43mm/5.6 is simply a scaled version of the 35mm/5.6. Angular field of view, relative illumination and design type are virtually identical. MTF is slightly worse for the 43mm, perhaps simply because the geometrical aberrations are scaled up slightly. I'm thinking the new 28mm from Schneider might be a departure from their long line of Super Angulon type designs.
-
It's hard to compare the Schneider and Rodenstock specifications and I'm probably making some mistake but if I convert Schneider's illumination fall-off into stops i.e. 50% is one stop, 25% two stops, 12.5% three stops then there doesn't seem to be a great deal of difference in fall-off between the Schneider 43mm and the Rodenstock 40mm. This seems rather surprising.
Having used the Rodenstock a bit it is phenomenally sharp even at F5.6 but on paper it has a lot more distortion. I wonder if the greater coverage the Schneider offers is borne out in practice.

Regarding illumination falloff, I think you are correct. Comparing MTF at f/5.6, the Rodenstock 40/4 looks better at 40lp/mm than the Schneider 43/5.6 does at 30lp/mm

Yes I think it will be very interesting how both lenses compare. The Schneider certainly has the bigger advantage on paper, but we also know that Rodenstock is quite conservative with their specs.
