Sony 1.4x Teleconverter (2016) User Reviews

Announced Feb 3, 2016 •
Teleconverter | Sony E

All shot, handheld from around 20' to 25' away, with the FE 600mm f/4 GM OSS mounted on an a1 and heavily cropped. AF acquisition and tracking is very slightly slower than the bare lens. Bird-eye AF seems the same as with bare lens. I cloned out a thistle above the head in the blue grosbeak shot. Processed in DxO PhotoLab, with DeepPRIME NR applied.

With the 1,4TC the lens becomes 280mmf8  to 420mmf8 to 840mmf9. IQ is good with little sharpness and contrast degradation,AF is slower .With a 24MP senzor the IQ is better than cropping.

This unit stays on my 100-400. I really can't notice any degradation of IQ with it on the lens. I'm using it on an a6500
