Q: 7. When used with an APS-C camera (e.g., a6300 or a6000), this lens becomes a 75mm focal length equivalent. Is there any change to the macro properties if the lens is used with an APS-C sensor? Does it still provide 1:1 macro? (Thank-you)

A: The lens' minimum focus distance and the reproduction ratio does not change when using the Sony FE 50mm f/2.8 Macro Lens on a Sony E-mount mirrorless digital camera which uses the APS-C sensor. The lens would continue to have its 1:1 magnification ratio and would have a minimum focus distance of 6.30 (16 cm). The lens' actual focal distance also remains the same, as the focal length of the lens is a physical measurement from the center nodal point of the lens to the sensor.The only difference is the lens' EQUIVALENT focal length. As you are using a smaller sensor, the sensor sees a smaller section of the lens' imaging circle; as such, you are seeing a cropped view. The size difference in the sensors requires a 1.5x multiplication to find the lens' equivalent focal length when compared to the same lens on a full-frame camera. As 50mm x 1.5 = 75mm, the angle of view of the lens would be similar to that of a 75mm lens used on a full frame camera. But you still retain the 1:1 magnification ratio and minimum focusing distance.

Q: 8. Do these have TTL?

Q: 9. Will this lens have audible focusing motors like the new cheaper 50mm f1.8 that came out this year? Or silent like the 55mm f1.8?

A: The lens is not out yet so there are no real world reviews and we have not seen one.Chances are the motor will make some noise. For it being as loud as the new 50mm we could not say. But most likely it will be a more quiet than that.

Q: 10. Does this moonlight come with a reflector? If so, which one?
