 1:10. Settis 6&7 plus CE with both figures aroud the outline was the key.

 Like Willi (took me a bit longer); additionally a box setti, eliminating 2 from C7, helped a lot.

Took also for me a while, but step by step solvable. No long HC needed. Very nice!

 Difficult for me and also a little unsatisfactory,
as the decision in column 4 was not possible for me without a (very long) chain, but then the solver rolls through.
So AD4 must be low

 After solver stop
CE col 4 removes 4 from B4
xwing 2 cols 78 removes 45 from A789
UR AC78: C7=4
Chain for J4=4 (still unsatisfying, not a head chain) removes all 3s from col 1

 very nice - 2 options for 2 in / diagonal - one option solved with no further chains (I am sure there is also a solution without this guess, I just couldnt find it)

 Touch one, needed a long, long head chain to find hi/lo in col.7. Some shorter HC before that needed.

 Not so easy this time. One number in D8 led to a quick contradiction..

 No 8 in Row f. This means either column 1 or 7 has no 8. Testing leads to a quick contradiction. This opens up the puzzle.

Any other hints to solve this beast? Pax gave the hint that 1 is not in E8, but I still have 4 and 8 in this field. Cole gave the hint that 8 is not in Box 4. But I still can not solve this str8t.
