I got these figures from dpreview. They haven't reviewed the E510 so I showed the E410. My understanding from what I have been told/researched is that they are almost the same except for lack of IS in the E410 (E410 is lighter, too and offers an underwater case - not important to me

) -
please correct me if I'm wrong on that!
What I am confused about is sensor size as it correlates with image quality. Nikon sensor area: ~370, Olympus sensor area: 243, yet per this review they tie in image quality. Am I misinterpreting this, or are you guys mostly talking about LOW LIGHT IMAGE QUALITY (which I am so concerned with

), where this review is looking at it OVERALL?
Is this worth putting any stock in? Found it on a dpreview forum:

I was just commenting on this on another thread, but I do not put too much weight on the DPReview opinions anymore. He is just too inconsistent. I don't know if it some sort of brand loyalty, he is in over his head, or just in a bad mood on some reviews, but it just does not make sense sometimes. Plus, he is part of
Amazon now, so I am a little concerned about his intentions.
As for low light, you are going to need a fast prime. That is pretty much accepted by everyone. With Oly, you are going to have to spend $400 and you will have to deal with the effective focal length of 100mm instead of the effective ~75mm on a C,N,P, or S. I personally think 75mm is a bit restrictive and plan to buy a prime a little wider when I can afford it. Only you can decide if this is a problem for your style. Then the other brands are less than half the cost for a 50mm.
As for the ISO, it is still a DSLR, so it will blow away a p&s, but it just will not get as good as the other brands with larger sensors. It is a matter of physics. It seems that Oly is addressing this by increasing the NR to make it appear less noisy, but you loose detail doing that. Look at the samples and see if it is good enough for you.
There are also a couple more unique things with the 4/3 system that I see as an annoyance, but you might actually see as a benefit. The DOF is always going to be larger on this system because of the smaller sensor. If you like isolating your subjects, this could be a problem. If not, it could be a benefit because it gives a little more room for error if you miss the subject on the focus lock. I cannot stand that it is in a 4x3 aspect ratio. I know that you said that cropping is not a big deal, but you are going to have to think that way when taking the shots or you will end up missing shots that you think were good because the crop ruins it.
I do not think any of us are saying that OLY is a bad brand. We are just saying that it has certain unique features due to the design and some do not like it because of that. Others like it because of those things, so you have to decide what is important to you.
