I used to use it as an addition to the whale, now it always costs as a regular one. People write a lot about curved autofocus. Here we must remember the materiel. Put any depth of field calculator on your phone, such as DoF Calc, and you will see this. If you shoot an object from a distance of 2 meters, then the field of sharpness is only 20 cm. That is, from the point of sharpness, only 10 cm in both directions. If between the moment of focusing and the click of the shutter you (or the subject) have moved 10 cm, then that's it - the picture is already blurry. And this is not a lens jamb, but just a feature that you need to know. So, for example, it will not be possible to shoot a person on a swing with an aperture of 1.8 in the standard autofocus mode (non-tracking). To make it clear, shooting from 2 meters with cool lenses for FX is generally unrealistic. For example, at 85mm f/1.2, the depth of field from 2 meters is only 4 centimeters! That is, if you focus on the tip of the nose, then the cheeks are already smeared. And if you swung a little, then in general the whole frame is in soap. And what, is it a bad lens?
