Sony FE 1.4X Teleconverter

Useful with a number of my lenses. Works well with minimal image degradation. Best teleconverter I have ever owned.

I bought this to give the 70-200 F4 OSSII more reach in sunny conditions. I read some reviews about image quality dropping, but i could not see any on the A7Riii. Definity a great purchase and together a great upgrade from the first 70-200 F4

Great image quality! The Autofocus speed on the lens is not affected by adding this TC.

Had my first outing with this today. Used it on my 200-600 for bird photography. Got some good images. Bit of a learning curve with the narrow field of view and focus can be tricky.
