We present the main results of our recent analyses of exclusive production of vector charmonia (J/ψ and ψ') in k_t-factorization approach and for γγ production of charged dilepton pairs in exclusive and semiinclusive processes in a new approach, similar in spirit to k_t-factorization. The results for charmonia are compared with recent results of the LHCb collaboration. We include some helicity flip contributions and quantify the effect of absorption correction. The effect of c c̅ wave function

... s illustrated. We present uncertainties related to F_2 structure function which are the main ingredient of the approach. Our results are compared with recent CMS data for dilepton production with lepton isolation cuts imposed.
