Cheapest RF lens?Talk about RF50mm F1.8 STM

RF50mm F1.8 STM with 50mm focal length, just from the name, this is a standard lens.The maximum aperture of F1.8 is not large in prime focus.The STM stepper motor doesn’t seem to take photos as fast as the USM.Without the macro features of the RF35 and RF85, it’s a mediocre camera lens. 

But it’s small and it is a standard camera lens, it’s F1.8 maximum aperture is big enough. The STM motor is smooth and not that slow. The point is, it’s cheap! So let’s talk about this camera lens. The size of the F1.8 Legion in Canon’s RF lens is well controlled.They are all relatively small and light.Among them, RF50mm F1.8STM, no matter what you shoot, you can take it with you at any time, occupying no space or weight.At the same time the standard lens can be said to be very useful, portrait and human street photography is the most commonly used.Encounter the right scenery, is also very good.So you can keep it with you, and it’s really an attribute that a lot of people value. 

The RF50mm F1.8 STM contains an aspheric lens.This is different from EF 50mm f/ 1.8STM.The addition of aspheric lens can better suppress the difference and improve imaging at large apertures.

As you can see from the screenshots, the focal plane is rich in detail, the texture is clear, and the full aperture sharpness is very good.

At the same time, although it is not as good as the RF50mm F1.2L USM, we can see the RF50mm F1.8STM’s out of focus blur is very strong and looks good.There is no obvious linearity.  When we look at STM, we always wonder if the focus is slow.If you have to compare it to the expensive RF50mm F1.2L USM, it definitely is.You have to trust the Canon full frame micro – stand – alone drive itself.Full-pixel dual-core focus is not for nothing.You don’t have to worry about focusing. 

One feature worth mentioning about the RF50mm F1.8 STM is anti-shake.Yes, the lens itself is not shakproofed.But with EOS R5 and EOS R6, you can get level 7 stabilization.It is to give full play to the body of the anti-shake performance.
