The Sony 70-200mm f/4 G II Macro and 70-200mm f/2.8 GM OSS are each workhorse telephoto lenses, and deciding between them usually comes right down to sharpness, pace, and suppleness in real-world use.

This issues in the event you depend on fast-moving topics or push your lenses past their native focal vary. The testing reveals delicate however clear variations as soon as teleconverters are within the combine.

Beneath shut inspection, textual content and positive particulars in clothes and helmets seem crisper via the GM, particularly with the 1.4x and 2x teleconverters.

The takeaway isn’t that the f/4 underperforms, however somewhat that the GM provides you slightly extra readability when the small print matter most.
One other level to note is how every lens behaves below totally different lighting. In good gentle, autofocus efficiency is nearly equivalent, however when situations get darker, the f/2.8 aperture reveals its benefit.

When you’re usually working in dimmer conditions, that benefit might weigh closely in your choice. Take a look at the video above for the complete rundown.
