On my Olympus OM10 35mm SLR camera there are less manual options. Whereas on my DSLR I have the freedom to set my own ISO, aperture, shutter speed, white balance and the option of manual focus, my 35mm only allows me to set the aperture and the ISO, and even the ISO can only be one particular setting based on the film I load. The lens however can only be manually focused as there is no AF function. The shutter speed on this particular camera cannot be manually set, the camera chooses it automatically based on my ISO and aperture.
