Our friends at sonyalpharumors posted a rumor heard from a trusted source saying that Sony will challenge Canon (and Nikon) on the full-frame front thru the pricing of their upcoming NEX full-frame cameras. It appears that Sony will soon announce two mirrorless full-frame sensor cameras, one of them (the cheaper one) is set to compete with Canon’s EOS 6D price tag. That’s to say that the full-frame Sony NEX will have a price tag very similar to the EOS 6D (on sale for $1499.99 on eBay) and the Nikon D600. I think these are good news: more competition will possibly lower the price of the 6D even more. The full-frame NEX that’s going to challenge Canon and Nikon could have a design similar to the Sony RX1 (see pic above).
