Does somebody know the image circle of the Rodenstock Sironar N 5.6 120mm MC ?
Basically I`m looking for a good and small 120mm lens which allows more than 20mm rise.

175mm... barely enough to move off center.
By contrast, the Nikkor 120/8 has an IC of 312mm. It's a marvelous lens.

If you believe you can, or you believe you can't... you're right.
I agree that one obtains very commendable results from all Nikkor SW F8 lenses; however, for shooting in low light it is a real challenge to focus particularly when extreme movements are required. Consider APO-S Sironar, APO Symmar L, or Super Symmar 120 f5.6. There was a recent post here for the last of these recently. If I recall correctly, it is still for sale and reasonably priced.
There is no APO-Sironar-S in 120mm.
The APO-Symmar-L 120/5.6 only has a 189mm IC.
The Super Symmar HM 120/5.6 IC is 211mm.
That's the largest IC of the 120/5.6 lenses in my database, which is not all-inclusive.

The requirements were 1.) good, 2.) small, 3.)120mm, and 4.) more than 20mm rise. The first two requirements are not specific enough to be testable, so are subject to interpretation. The last two are not.
I didn't see "fast" on that list, except as implied by using the Sironar as an example.
I think I have to agree that an f/8 biogon derivative like the f/8 Nikkor SW (or f/8 Super Angulons, or f/8 Fujinon SWD, if they were made at this focal length, which I don't recall) will come closest to fulfilling all these requirements.
Plasmats are more compact, but at the expense of coverage. The newer versions (APO-this and Super-that) might have better coverage--I don't keep up with such unobtania--but at the expense of being compact.
I have a 121/8 Super Angulon, and it's a beast compared to a plasmat. But it provides abundant coverage. At the opposite pole, I have a 127mm f/4.5 press lens, which is a fast (for LF) tessar, and it's much more compact than any plasmat or biogon derivative, but it barely covers the corners (by undermining that "good" requirement) with no movements.
So, SW, SWD, or Super Angulon for coverage, f/8 for smallness (to the extent feasible given other requirements), and they're all good.

The 120mm Sironar-N had a very short production span. It covered 175mm at infinity at f22. It was discontinued in 1992.
I thank Leigh for the corrections.
Fuji 125mm f/5.6 if you can stand another 5mm. It's what I did and it will cover 5x7 with just a few mm to spare. And it's small.
Search the forum for it and you'll have your answer.
