hi alex

RR lenses ... they are versatile and convertible
i am not familiar with the one that you now own,
but i have 3 or 4 other ones and really like how they render an image ...
you might front focus ( focus in front of your subject )
to see what your DOF is like, and how your out of focus areas look.
you might also consider removing one of the elements, you will probably loose 1.5 fstops
but it will be worth it ...

have fun !
