    I do not see anyone simply testing the a7R against a7S IN NORMAL DAY OR FLASH LIGHT.
    EVERYONE RUNS to the latest selling point, but I just want a simple comparison for image detail, contrast range SINCE we have such DIFFERING type sensors.
    So, compare, pacifically , the new large pixel vs. the older technology of 36 megapixels.
    I have reputable reviewers say the a7S is like a medium format camera….well help us see the difference.
    I may want a more detailed camera image…but maybe they are equivalent for a landscape where I can afford to use f16 and 3/4 sec. HELP!
