Re: Is a Macro Lens Useless If You Can Crop With an A7R3 or A7R4?

One thing you are forgetting is perspective.

A lot of people say 24mm is bad for portraits because it's distort faces. 85mm is better. That is true but the focal length of your lens doesn't actually distort anything or change the perspective. The change in perspective happens when you step forward or back to frame your subject. So unless you can shoot as close to the subject, you won't get that sweet sweet macro look.

Also DOF does depend on the focal length of the lens. So even if you took cropped an image with a 24mm lens. It won't have the same shallow DOF as an 85mm. If you stepped back with a 135mm 1.8 and cropped for a macro shot. It won't have anywhere near the DOF of a 100mm f2.8 right up to the subject
