Thanks, this is quite informative, Davis! So you think the e-30 has somewhat more noise than the e-520 at iso 800 and 1600? But it doesnt show up in 8 x 10 prints? Also, people talk about banding with the e-520, but I never could see much of it at iso 800 or 1600, what about you? I would think you couldnt tell any difference in an 8 x 10 print between an e-30 and an e-520?
From the 100% crops that I've seen, the E-30 has more noise, but it isn't really a big deal from the results I've seen with the camera, which have been great. I personally was considering purchasing the E-30 until I considered some trips I was thinking of going on and a great deal on the E-3 that I just couldn't pass up.
I have printed iso 800 & 1600 shots from my e-520 and they look great. I was initially worried because I noticed the noise on my monitor, but the images came out really clean. This is before I even got my noise reduction software.
On an 8x10 print, I believe an e-520 & an e-30 shot will both look great, as long as you get the exposure right and/or fix/edit anything you think you need to once you import it into your computer (only if you think it needs to be fixed/edited. if not, great!).
