The TLR goes one step further, by using second viewing lens but it is the Single Lens Reflex SLR that solves the problem fully. When the photograph is ready to be taken the mirror is retracted allowing the light to pass through the lens and able to accurately determine precisely both the focus and depth of field. With the shutter positioned just ahead of the film within the cameras body it is possible to change lenses without exposing the film making the design very flexible.

Another common feature of SLRs neccesitated by their construction was the need for the light to pass directly to the film, when the shutter is opened.

the photographer is truly viewing through the lens to the reflex mirror unhindered, this lead to the shutter mechanism being placed just in front of short bellows.

This is how people perceive the SLR with the distinctive prism housing on top that first appeared on Contax camera in The principle shortcoming is that the focal plane shutter uses variable gap to vary the shutter speed and that only longish exposure time will synchronise with flash.. The rangefinder camera determines what should be in focus without actually demonstrating the degree.

The rangefinder camera determines what should be in focus without actually demonstrating the degree. As already discussed, focus is fundamental to photography, both in terms of what is and what is not in focus. The principle shortcoming is that the focal plane shutter. The prism serves to reflect and flip the mirrored image from the ground glass screen to the viewfinder, resulting in an erect and true image which is bright and often magnified by the viewfinder optics.

As already discussed, focus is fundamental to photography, both in terms of what is and what is not in focus. The rangefinder camera determines what should be in focus without actually demonstrating the degree. The use of 35mm film allows these cameras to be relatively compact which removed one of the SLRs drawbacks.
