    Here are two photos I took today. I mounted the E-M1 on a sturdy tripod and shot both lenses at 20mm, f14, 30 seconds. With a 9 stop ND filter. Which is which?

    Nice images, but under those settings, I am not sure I would expect to see as much lens "character" as I would from the sensor and/or your post processing.

    I processed both in Darktable with the same settings.

    f/14 is past the point of diffraction for both lenses, at f/14 the vignetting is gone on both, there is motion blur in the clouds and water and the shadows and darks are mostly clipped near to black, so there is no detail to look at, and there is no need to consider bokeh with DOF at those settings. What's the point? The 15mm lens cap lens might have done the same.

    by the way -- nice images.

    Diffraction limits resolution. It doesn't defeat it. In most cases the kit lens out resolves the P20 from f10 to f22, and is so similar at f5.6 to f10 that it's impossible to tell them apart. When I shoot long exposures, I use the kit lens.

    As already said you have diffraction. In 30 seconds, with wind, maybe also micro camera blur. Then the light hitting the rocks changes from the first to the second one, and that alone could make all the difference. Add scaling down, jpeg compression...

    You don't need to use expensive zoom lenses to get great photos.

    I suspect that everybody's answer to that question will depend on the subject being photographed, and the conditions under which the photograph was taken. But you have provided some nice images that show a kit lens can hold its own in many a situation.

    Lovely pictures Datagov,
    F14? :smile: Can you repeat it using the bottom of a coke bottle? : I'm sure I'd be able to tell which is which.

    Great picture!

    Nothing more to be said on the lens bit.
