I photographed exactly the same scene,a yacht marina,on 35mm Rollei Pan 25 that I previously photographed on the former Maco UP 25,which has been said to be te same as Efke 25.I exposed at EI 12 and developed both in Neofin Blue 7-8m 68F.
On 11x enlargements I could not see any difference beween them.Very fine grain, finer than T-max 100,and with both I needed a loupe to read the boat names on the prints.
I have had the occasional frame of 35mm Efke 25 with a defect but have not used enough of the Rollei Pan 25 to say if it is any better in this respect.
Hard to choose between the two.
