If you are a small mammal and/ or bird photographer... you know. Still tack sharp and despite losing a stop of light, photographs came out lovely and compensating for the light loss is generally not an issue.

I am using it with the Sony 70-200 f/4 OSS II and it works perfectly extending the zoom to 280mm at f/5.6. I have not had any issue with the speed of focusing or anything else for that matter. Photos look fantastic. It is very easy to install or remove and comes with a well designed carrying case. No complaints, does as I need, and it will get plenty of use.

The adapter is compatible with Sony e-mount bodies but only certain e-mount lenses (e.g., Sony EF GM 100-400, Sony EF GM 70-200 f2.8). Check the Sony website to confirm the extender is compatible with your e-mount lens.
