    This was put up on 43 Rumors two nights ago. I have been looking for evidence of the claimed 14 stops of DR that Olympus claimed in this interview.
    Olympus Q&A: Olympus OM-D E-M1 II Sensor Size Trip

    So far I have not seen anyone show any improvement but any time it's looked at they look at shadow recovery. This test shows a big improvement in the highlights vs the mk 1.

    It's in Korean but easy to see the pictures and what was done. It's not definitive but shows that the em1 II. Might be much better for recovering highlights.

    I don't read Korean, but I love the Google translations on the comments; "high-speed open-air love performance".

    Interesting. Part of the issue looks like metering though. The -5 EV shot is notably lighter on the E-M1 for example.

    I am sure there are people who actually care about this kind stuff with regards to their photography and good on them... but to 95% plus of photographers this should not be of concern....nice thing to have, but will not change your photography in any way perceivable to you or your audience

    just my opinion

    posted here for the sake of balance

    agreed.. I am a grump...

    but until my grump becomes a final croak I will continue to argue that minor incremental changes in sensor technology do not actually change the photographers opportunity that much. They are nice to have but not game changing

    Still looks about 1 stop better in the Mark 2 though. Interesting. And more resolution, too.

    I disagree. If you do landscapes 1 stop improvement in the highlights means a lot. If you do portraits and street maybe not as much but a significant amount of Olympus owners use them for landscapes. I got into m43 as I had a system I can backpack with. If I have time I will stop by my local camera shop to see if I can replicate this.

    You are welcome to disagree... In my opinion if traditional landscape photography is truly your calling/your driver, then m43 is not the platform for you... it cannot compete on any of the technical parameters that landscape photographers seem to hold so dear.

    I seriously doubt that a significant number of olympus users shoot landscapes that require the improvements in highlights that you...highlighted

    if it's not important to you then don't comment. For some of us this could be a huge improvement.

    Well, Kevin - I often agree with you, but not this time. I do a lot of landscapes and m43 is not a poor choice. It's light and compact, which matters a lot if you have to hike to the location, and it has a number of useful features such as LiveTime and LiveComp which better most other systems. Hi res mode has uses too. DR is the biggest technical challenge with landscapes, so extra highlight room is very welcome.

    Think I'm going to agree with both and disagree at the same time
    There have been great landscape shot with far lesser cameras than the M43 gear now available, it may not be the ultimate but I suspect in that case the user really should already have medium format digital. So I agree that m43 is eminently suitable.
    What I don't get and I'm happy to be educated is this constant drive for more and more dynamic range. To me high DR ends up looking false, lanscapes have deep shadows and bright bits and why do we need to find every tiny detail all the time. We have plenty of ability to do DR bracketing if desired and even I've done that for sunsets at times.
    So I can't agree that we really need more DR but I get that for some it is highly desirable

    Well Phil - consider this image:

    29169457724_60280e1f9b_b.jpg
    Sprague Lake by Paul Kaye, on Flickr

    The DR looks OK - right? Yes, but only because I used a long exposure and "dodged" the top of the image with a black card during exposure using LiveTime. If I'd have shot that in a single exposure I can guarantee that either the sky would have blown out or the lake would have been in so much shadow that it would have been hard to recover it later. Even an extra single stop in DR would help such a situation.

    I rest my case m'lord!

    Hi Paul
    Respectfully no I don't think it does but that is a personal view, to me the more traditional use of a graduated ND filter would have delivered a cleaner more realistic look imo. It seems the traditional methods used for film are put on the wayside due in part from the excellent DR we have available and the need to do it all in one shot.
    Anyway lets not augue semantics, I do get why some more DR is desirable but like (puts on flame suit) BIF photo's the minority of people overall that use it for that is disproportionate to the number of threads on the subject :) not saying DR has a bunch of threads nor would I say no to an extra stop.

    PS fairly certain I couldn't take that phot myself so take any implied or actual critic with the grain of salt it likely deserves :)

    I agree that trying to her more DR in software can look poor if not done right but tha doesn't mean that more camera DR is bad. If correctly processed a higher DR shot can look great. I could just exposure bracket but that is even harder to make look natural compared to one shot. the Nikon d810 has 14.5 stops and is the camera of choice for many professional landscape photographers because of the high DR. I don't see many d810 owners complaining that there is too much DR. The camera doesn't make the shot look unnatural, it's the post.

    I think I looks natural to what a human eye sees. Does it look like a sooc shot, not really but that is fine. It's all about what you want in your picture and I think that looks great.
