 A possible start consists in the determination of the ranges, i.e. high/low along the diagonals. This should be possible by careful examination and yields at least a few digits. The rest is a matter of perservarance and will probably take some time. Good luck!

@Cosmanita: A2=1 (mandatory single) which solves range for / diagonal (e.g. upper part of / diagonal has to be 4-7 and lower part of / 1-5) which solves D23 and E123 and leaves only 2 options for F6
easy to spot (although it took me some time) that B8 cannot be 7 which leads to a naked quintuple in row B etc etc. all can be solved with logic (although I confess that I had to use a few short chains/headchains, happy to share more but wanted to follow good sense not to share full solutions or give candidates
