Chapter 1 - Know your K-7
Page 46
Dust and Humidity Resistance
We can say farewell to the camera
enemies; dust and humidity. First and
most importantly, the Pentax K-7 is
built around a solid stainless steel
chassis, surrounded by a lightweight
magnesium-steel alloy body. The
DSLR camera feels very professional
and very solid. The addition of non-
slip material at all strategic locations,
makes holding the camera comfort-
able and safe. The camera has 77
seals protecting the internals from
dust, humidity, rain and snow. This
feature alone is not available any-
where on cameras in the K-7’s price
range. This feature is usually found on professional cameras costing up to five times
more. It makes me wonder what exactly defines a “Pro” camera! Is it a camera that
costs thousands? Is it a camera that allows one to make money? In the glory days of
film based cameras, professional cameras were the big and complicated cameras that
required extensive training to operate. Today, digital technology has certainly re-
duced the gap between consumers and professional photographers. The K-7 is defi-
nitely not your father’s camera.
File Formats
Most DSLR now have the capability of saving the digital photos data in JPEG files,
RAW files and RAW + JPEG. Saving in JPEG is quick and the final photo is gener-
ally of excellent quality. Many photographers, including myself, prefer shooting in
RAW mode and adjust the photo’s white balance, color, saturation, hue, sharpness,
and contrast. Superior results can be achieved that way, but it is time consuming.
Why not save in RAW and JPEG and decide later which photo you want to manipu-
late further? It is difficult to modify JPEG files extensively, especially in the shadow
areas. RAW files give a much broader range of manipulation.
