M4/3 System

Panasonic GX8: 20Mp
at High ISO Example...
Amazed at Feather Detail on a 20Mp
M4/3 camera at ISO3200.
Trying to photograph a small bird
recently in very poor light recently, I had to push my GX8 to ISO3200
and was truly amazed at the result ...
Of late my interest has leant towards
photographing nature and it appears that nothing shows up lack of detail
more than photographing birds. Loss of resolution due to any of the
following; a soft lens, slight miss-focus, smearing due to high ISO
noise reduction, poor stabilisation, or simply not enough pixels to
resolve the fine soft feather detail, can all leave an otherwise
excellent image containing feathers looking like a cheap water colour
painting.

The early evening light was appalling, being both dark and
overcast. This shot was taken
handheld at ISO3200 using the Panasonic 100-400 lens set at
350mm.

The image is dull, but the detail and lack of noise from the
GX8's 20Mp sensor, prompted
further thoughts as to might be obtained with a little
processing from RAW.

RAW Power...
I was so surprised by the lack of noise
and impressed by the feather detail from the above out of camera jpg,
and from an image shot in such appalling light that a Nikon user beside
me said let's call it a day, I thought I would have a play and see what
sort of result could be extracted from the RAW file and whether I could
in fact better the in camera jpg engine. Frankly I was amazed at the
benefit a few minutes with Lightroom could bring. Below is the result

Frankly I was stunned at how well this 20Mp micro Panasonic 4/3
sensor produced
this much fine feather detail, in such poor light, and at such high ISO.

Progress or Not...
Camera forums frequently abound with
derogatory statements about how poor M4/3 cameras are at high ISO
because of sensor noise. Some so called M4/3 fans moan there has been
little progress of late and frequently say the increase from 16Mp to
20Mp was a waste of time and produces more noise with no other
improvement. However have I got news for you... that has not been my
experience when photographing indoor action sport such as roller-derby
or when photographing birds.
I have now been an M4/3 user for around 8
years and although I initially used the original 12Mp Panasonic G1
alongside my 24Mp Sony DSLR, however since Panasonic introduced the 16Mp
GX7 with all its wonderful features, the DSLR has quietly sat in its
case. I was fully aware that I had to be more careful when composing as
the loss of pixels and thus resolution was certainly noticeable, but for
the commercial work I have been doing 16Mp was far more than adequate.
However when it comes to my hobby I am
ultra critical and the Panasonic 20Mp sensor as implemented in the GX8
has proved to be a marvel of modern engineering.
