The mere existence of the Reporter was Leitz's admission that a Leica takes rather a long time to reload. In those days 250 shots without stopping was no doubt ground-breaking. Now we have digital cameras with big SD cards that can go for weeks or months without downloading files.
There is, however, normally an inverse relationship between the number of shots you have available and the quality of the pictures. 5" x 4" photogs rarely waste a shot. I can take 300 pictures with a digital camera and nearly all of them will be instantly forgettable. With film I reckon on a hit rate (i.e. this could go in the album or on a wall) of 33%.
