is olex still doing plmount conversions?
Hi. I do not make PL conversion of old LOMO prime lenses with OST-18 lens mount version of lens housing, because, the similar optical block can have OST-19 , Konvas-2M version of lens housing.
OST-19, Konvas-2M version of lens housing better for PL upgrade.
From other side, old, LOMO wide angle optical blocks have short back focal distance and can give a dimension limitation.
My last PL upgrade 28 mm LOMO OKS-4-28-1
