Review on Canon EF 40mm f/2.8 STM Lens - Fixed Black (6310B002) for US Cameras by Ryan Limkk ᠌

Completely disappointed because I took it for the video. But still I’ll leave it for shooting with a stub, because it’s light. Perhaps the motor will be almost inaudible with a directional micro, this is hypothetical, I have not tried it yet. Pros: Compactness, lightness. Not a bad picture for a budget employee. Not bad as a photo lens. Got cons: Absolutely not suitable for shooting video if you use focus. Engine noise (STM) is very strong. Attention! The motor works even with manual focus!
