Sony is rumored to be announcing two new camera bodies in May. The Sony NEX-F3 is said to be replacing the now discontinued C3, which has been the most affordable NEX camera to date. The F3 will feature a large 180-degree flip-out LCD, much like the one found on the Samsung MV800. This is going to appeal to those who take self-portraits. It is a feature that not all will appreciate, but there is definitely a market for it.
Is also rumored that Sony will be announcing the Alpha A37 DSLR camera, which will presumably be the new entry-level model in the Alpha lineup. Nothing else has been said regarding its specifications and features, but Sony has always equipped its entry-level DSLRs with high end features.
In addition to the two camera bodies, Sony is said to be announcing two new lenses. One of the lenses will be an E-mount lens for NEX cameras, and the other will be an A-mount lens for the Alpha DSLR cameras. There have been images floating around of a new 18-135mm A-mount lens, so that would be my guess for one of the new lenses.
