This lens is designed for digital cameras  with APS-C sensors.

So, the image circle is not enough for 35mm full  frame.

I  confirmed its image circle by a film camera Z-50P.

A  focal  length  of  more  than  around  24mm  is  useful  for  35mm  full  frame  cameras.

 

Z-50P is a film camera debuted in 1993.   DAL18-55mm was debuted in 21th century for digital cameras and it has no aperture ring.
Can
Z-50P control  DAL18-55mm ?

 


Z-50P shows shutter and aperture.

 

The aperture changes according to Z-50P.

 

I think this combination offers proper exposures.

 

How about SFXn ?    SFXn is a film camera debuted in 1988.


Neither manual nor aperture-priority is displayed.
Program and shutter-priority are displayed.  But it does not look like that the aperture of DAL18-55mm changes correctly.
