Viltrox vs Sony 2x Teleconverter (E-Mount) — Sharpness Chart + AF Test

Can a budget third-party 2x teleconverter replace Sony’s original 2x TC on E-mount? In this video I compare the Viltrox 2x teleconverter vs the Sony 2x teleconverter, focusing on real use cases, sharpness (test chart + crops), and autofocus performance (tracking + rack focus). What we cover: When a teleconverter makes sense (and when it doesn’t) Sharpness + CA comparisons on a high-res test chart (center vs corners, multiple apertures) AF tracking consistency (cars) + rack focus behavior Who should buy the Viltrox vs who should stick with Sony Gear used in this video: Camera: Sony A1 Lenses: Sony 70-200 GM II, Sony 200-600 Teleconverters: Viltrox 2x TC, Sony 2x TC Tripod + printed high-resolution test chart Key takeaways from my testing: Image quality: Sony is generally cleaner/more consistent wide open and at the longest focal lengths; Viltrox can look very close when stopped down, but may show more CA depending on the setup. Autofocus: Sony is still the more predictable/reliable option, but the Viltrox gets surprisingly close in most situations. Value: If you’re just getting into teleconverters and want to try the “super-tele” experience on a budget, the Viltrox is compelling. If you prioritize long-term support, sealing confidence, and maximum consistency, Sony is the safer bet. 👇 What setup are YOU using a teleconverter with (70-200, 200-600, primes)?
