  • Oly compared favourably with Canon full frame

    [ame="https://www.youtube.com/watch?v=OGn3yPl59ZM&feature=share"]Full Frame vs Micro 4:3 - Where It Matters Most - YouTube[/ame]

    Marc Newton make huge (1 metre) prints and can't see the difference.

    Obviously he's only considering resolution, not e.g. dynamic range, but still rather encouraging.

    That fits in very much with my experience, although none of the subjects were challenging from the point of lighting conditions, where dynamic range and/or ability to handle high ISO might come into consideration.

    It you were to take non-flash photos in a museum or to do a bit of street photography in Australia or New Zealand, where there is a requirement for huge dynamic range, you would probably notice a bit of a difference.

    It was pleasing to see that the 4/3 cameras are getting closer.

      Interesting video Rob. It actually looks like a good course, wonder if anyone here has any experience of it?

          Interesting that he still quoted 20 megapixels for the Oly when actually he had reduced the number of usable pixels as he was is 3x2 format which loses quite a large quanty of pixels,I would think that the effective pixel usage of the Oly is about half of the effective quantity as the full frame camera.

            I would think the 3x2 aspect ratio would affect both cameras equally.

              It appears that the current 'rush' to full-frame is driven by people who like to take their photos in the dark


              The video linked in the original post shows that more pixels are irrelevant to normal photographic needs, so I suggest a radical opportunity for Olympus to embrace the low-light fad by introducing a pixel interpolation mode in their cameras.


              I used to use a Nikon D70 camera with 6MP and this provided images of acceptable reproduction quality for agencies such as Alamy. I changed to Olympus simply to escape the size and weight of traditional systems.



              If a 24MP sensor included a 2x2 pixel integration mode, the noise would theoretically be reduced by a factor of two, moving the MFT sensor into the range demanded by the low-light aficionados, while providing image resolution equivalent to my old Nikon

                  That is very interesting. I sometimes do this manually in Photoshop, by using Gaussian blur on areas behind the subject but it doesn't give the graded effect shown in Ken's examples - see, for example, the handrail. The software does make some mistakes though: look at the post supporting the weather station, where a dark mark on the post has been interpreted as a notch. I assume that the software detects the amount of de-focus at each point and amplifies it to produce the effect.


                  Ken, typically, makes a controversial statement that "with the same lens there isn't much difference in depth-of-field with just a one-stop change in aperture. You need at least two stops to see much difference; camera companies love it when they get people to pay for f/2.8 zooms when f/4 zooms look almost the same for throwing backgrounds out-of-focus."

                    The wide aperture effect can be achieved on any twin lens iPhone by using an app called 'Focos'.

                    I have tested it on an iPhone 7+ and it successfully reproduced a wide aperture effect on a portrait shot. The basic app is free but there are in-app purchases for more sophisticated effects - I've not tried these.




                    I feel sure that Olympus could achieve something similar, through an extension of the focus stacking function, but I suspect they prefer to sell expensive f/1.2 lenses.
