Did you copy something from this article? I only see your personal experiences here.

Sorry, I meant I copied it from my comments on a News article - didn't realize at first that I wasn't in a forum.

Anyway, thank for all of that, and to the many others with excellent observations and analysis. (Historicity Lawrence, for example.) I'm quite surprised at how busy this place is ... having visited dpreview.com for many years but "joining" just yesterday. What a lot of replies in a very short time!

I'm having difficulty finding out what kinds of sensors are in which cameras. I have found that the E-620 has a Panasonic Live MOS sensor. Is that good? What would be better? (Why?) Where would I find that? Apparently, all of the FT E-Series cameras use Panasonic sensors.

Is the small size of the Olympus E-Series sensor really not a limitation, compared with larger sensors with Nikon, Canon, etc.? Isn't there a correlation between sensor-size and low-light performance?

Compared with much larger sensors yes, but not slightly larger. People talk about APS-C as if it's a standard size but in actuality they very. Some sensors considered APS-C are closer to 4/3rds in size than other APS-C sensors. (Like Sigma APS-C). The size difference between 4/3rds and APS-C is often more in peoples heads who want to feel superior about their Rebel or what have you. But I understand this perception because Olympus bought noisy sensors from Panasonic for years. The OM-D is as good at high ISO as the best APS-C sensors, which to some is a miracle but it's more that they bought from Sony a much less noisy sensor. Of course when you start comparing to 35mm, we are talking a huge leap in area and there is a limitation (though not as much as you might think unless you really want to push RAW files in extreme situations). Basically, there is a correlation, but it's not linear. You have to increase the area very significantly to get small gains and there just isn't much in the size difference between APS-C and 4/3rds.



So, I think I'll go ahead with that Panasonic 25mm f1.4 lens if I can find one.

Thanks very much again.


P.S. Any idea how many E-Series cameras Olympus has made? It's not always even mentioned after Nikon and Canon, Pentax and several other "newer" camera-manufacturers.

What if the hokey pokey really is what it's all about?
