Sony officially announced what had been floating around the rumor mills the past weeks: two full-frame 35mm mirror less cameras, the Alpha 7 and 7R, which Sony claims are the world's smallest and lightest in their category.
The two new cameras join the A99 DSLR and RX1/RX1 Cyber-shot models in Sony's full-frame lineup, borrowing design cues more from its compact RX1 and NEX cameras than the larger Alpha DSLRs. Designed as a small and lighter full-frame alternative for both pro photographers and advanced amateurs, these solidly constructed magnesium alloy bodies are weather-sealed for dust and moisture resistance. The A7R uses a 36.4-megapixel Exmor CMOS sensor that Sony says is the highest resolution sensor it has ever made for the Alpha lineup, and, following a recent industry trend, eliminates the anti-aliasing filter for sharper details.
The A7 has a 24.3-megapixel sensor, but uses a hybrid autofocusing system. Both cameras feature the newBionz X image processor, which Sony says is responsible for handling much of the heavy lifting like fast autofocusing, Full HD video, and low noise – allowing for a compact camera to utilize a large sensor while delivering DSLR-like performance.The cameras will go on sale in December. The A7R will be priced at $2,300 (body only), while the A7 will be listed at $1,700 (body only) or $2,000 with a 28-70mm f/3.5-5.6 full-frame lens.
