1 The Sony a7III can Zoom with a Prime LensThe Sony a7III has a crop mode which ensures that APS-C lenses can be used. This means that if you are trading up from the a6500 or a6300 then the lenses you use on those cameras will work using the crop mode on the A7III. The crop mode just uses the centre of the sensor, in effect turning the full frame sensor on the A7III into an APS-C sensor. This makes this camera so versatile. However, because there is a 1.5 crop factor between full frame and APS-C it means that if for example an 85mm prime lens is used. The crop factor can be turned on and it will convert the lens to 128mm. How do we know this? Well, check this video out 2.38 minutes in.
