  We present the main results of our recent analyses of exclusive production of
vector charmonia ($J/\psi$ and $\psi'$) in $k_t$-factorization approach and for
$\gamma \gamma$ 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 $c \bar c$ wave function is
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.
