|Notes: The model 315 is basically a model 210 with a new number. No new features were added, but the number curiously did not correspond to its prior model. It could be that Polaroid wanted to give the user the illusion that they were getting something better than the base model, which should have been called the 310. They may also have intended it to be in their line of cameras, but for it not to sell well. To be realistic, the imagesizer viewfinder was not very usable and probably caused many blurry photos. The next series of cameras would do away with this type of viewfinder.
