(Sony Alpha 7 II) photomicrography

A7R II

Many fanatsize that high megapixel sensors are wasted on optical microscopes,
presumably supposing perfect optics with ideal MTF.
Meanwhile, in the real world, deconvolution (or unsharp mask) is wanted to compensate less than ideal optics.
Bayer color filter matrix means that claimed 32mp cameras resolve only 8mp for red or blue colors.
Good unsharp masking wants 5x5 pixel arrays to convolve with 2 pixel stride,
thus a good 8 megapixel image should start with at least 128 claimed megapixel capture.

Having owned Canon DSLRs and lenses since 20D,
R5 or R6 would be an obvious 35mm sensor mirrorless body choice,
but Sony's A7II at less than a third the cost suffices.

why A7 II

  • enough pixels
  • USB power, tether
  • live view and electronic first curtain shutter to minimize photomicrograph motion blur.
  • available thin M42 adapter for parfocal microscope attachment
  • Some EF to E-Mount adapters control Canon EF lens aperture, image stabilization and autofocus.
why not
  • lacks focus bracketing, silent shutter
  • lacks Bluetooth
  • lacks full articulating screen   (unavailable until A7RIV)
  • A7R II is significantly better (but more costly)

    Sony FE 28-60mm F4-5.6 Zoom Lens - E-Mount

    item:      204844435127
    Condition:  Used

    Selling a Sony 28-60mm f4-5.6. Its a perfect size for either A6XXX or A7C bodies,
    otherwise I know a lot of people that put these lenses on their A7R's
    for travel as they perform phenomenally for a kit lens.

    It's missing a small pastic appearance ring on the front that covers some screws.
    It fell of moments after I started using it, I contacted Sony about this months ago,
    they offered to fix i and never got around to doing it.
    They assured me that it wouldn't affect operation and wouldn't let any dust inside,
    as all the glass is within a separate casing.

    Comes with front and rear caps.

    I will ship quickly and in a well packed box.
