    Default E5 dynamic range

    Looking at DP Review's review of the E5, Olympus E-5 In-depth Review: Digital Photography Review, am I right in assuming that the dynamic range of the E5 is 3.5 stops above mid grey and 5 stops below mid grey?
    So if I meter for the brightest part of the scene and open up by 3.5 stops the highlights should not be blown?
    Or am I completely out to lunch here?

    Your probably going to be close. I used a three stop ND grad on sunrise shots. That and a little help in Lightroom. The dynamic range isn't a Olympus strong point.

    No, I think it means that you meter the lightest and darkest point in the scene and expose for the mid point and hope it isn't more than 7-8 stops...or give up on the shadows.

    Yes, that is a more accurate statement.

    the dark side is limited to the amount of acceptable (to DPR) noise
    and the bright side to the point where highlights break

    on fix for this limitation was to stretch the tone curve by using ISO bracket
    this gives you 3 identical frames, each separated by a stop in e/v due to manipulating the jpeg gain
    merging these together is a straightforward process that gives more tonal depth

    one nice thing, E5 doesnt have very fragile highlights, its quite robust
    but M1 exceeds its DR by 2 stops, but is I think a little more fragile

    But isn't there more details in the EM-5 shadows?

    Im speaking purely jpeg, but yes of course
    but interestingly only goes that 51/2 stops into the shadow side same as E5

    flip Auto Grad to Auto and M1 shows itself to have a massive 7 stops on the shadow side
    but loses a 1/3 stop to M5 on the highlight side

    both these new Sony sensors can take a lot more noise than the previous Pannys
    eventually very dark areas seem to turn to black where noise is a lot less offensive and I guess harder to measure

    having better noise control in the first place menas the new cameras can do things which would be horrific on a Panasonic sensor
    but at its best in low noise conditions E5 still have very good resolution

    That is more a JPEG limitation than a camera limition, I would think.

    To be honest, I don't care about JPEG DR, as the RAW file has a much greater leeway, and I use that. The latest Panasonic sensors (GH3, GX7 and GM1) seem to hold its own compared to Olympus/Sony. At least that is my experience.

    I dont agree, not with Olympus
    RAW has a lot of worthwhile attributes in overall flexibility
    a well chosen setup in jpeg gets awfully close to RAW output
    its more about jpeg limitations than some mystic sauce in RAW

    It's OK to disagree

    But I have never been able to set up a camera's JPEG output to be so good that I don't need to touch it afterwards. So for me, shooting in RAW and processing them in LightRoom is both quicker and gets better results. Then again, I am only photographing for a hobby and also enjoy tinkering with my photos.
