For years on a large gap existed in sensor size between digital compact cameras /
megazoom on one side and DSLRs/MILCs on the other. The former were all equipped with sensors smaller than 1/1.6" (48.5 mm
2), whereas 4/3" (225 mm
2) was the smallest sensor to be found on DSLRs/MILCs.
The above mentioned gap was at last bridged by camera models announced on Sep. 2011.
On the "compact" side of the previous chasm, a very large (for a compact) 2/3" (58.1 mm
2) sensor will equip the high-end compact announced by Fuji on Sep. 1st 2011 (Fuji X10). At the same time, on the other (DSLR/MILC) side of the collapsing chasm, Nikon announced (on Sep. 21st, 2011) the
Nikon 1 system, built around a new sensor format they named 'CX' (13.2mm x 8.8mm, that is roughly 1" in the
inch system).wikipedia.com
