The Sony AR74 and the Sony 200-600 f5.6-6.3 lens, a non-functional combination for birds in flight?
At Gigrin Farm, every one of approximately 1,000 shots with the Sony A7R4 and 200-600mm was out of focus — 100% failure rate — and a replacement lens made no material difference: 5% critically sharp out of 315 shots at Andover where the focus point was on the bird. Even when the AF points and the final focus point were both directly on the bird, only 6% of those shots were critically sharp, confirming a system-level flaw that Sony has never formally acknowledged.
