Four-Thirds sensor types for next camera
In reply to ctlow, Jan 22, 2013

Hi Charles,

Apparently the E-620, E-30 and E-5 all have the same 12.3 MP Live MOS sensor. When Olympus created the E-5 they upgraded the E-3 to put the better sensor that was already in the E-30 and E-620 and to reduce the AA filter. I think it's a fine sensor. Everyone seems to rave about the Sony 16 MB sensor Oly put in the OM-D EM-5 for it's higher ISO performance and better resolution. Some people like the 16.1 MP Panasonic sensor in the Panasonic m4/3 GH-2 and GH-3. We all expect the next DSLR camera, later in 2013, to have the Sony sensor or the next better one that may be available for development now.

The 36x24 mm sensors in Canon and Nikon "full frame" DSLRs have an adavantage of low signal to noise ratio or High ISO performance, resolution and DR compared to the 4/3 size sensor in Olympus. There's not much difference in size between 4/3 and APS sensors. For the FF sensors there is a considerable cost for the same weatherproof, rugged, mag alloy body. Also compare the lenses required for the two systems. Compare equivalent focal length lenses at the same f-stops. For FF you need all the best f/2.8 lenses to get the high IQ that it offers. When you get to any telephoto lenses Olympus has a big cost and size advantage. When Olympus builds a new DSLR with the best 4/3 sensor available today then the differences in high ISO performance, resolution and DR will be a lot less.
