Hello, this is Dr. Ho, Film Camera.
Since it was usually used by newspaper reporters, the recently used F4s are in poor condition.
Even if it looks fine, it can be a body that has been through all prenatal prenatal treatment.
F4 was called the second identity of newspaper reporters. It is said that the reason why newspaper reporters were able to survive from the police club in the early 90's at the scene of a tear-pumping demonstration was because they also recognized the F4. Newspaper reporters used it a lot, so F4s that run around in secondhand should be questioned about their longevity. Although the F4s of these newspaper reporters were used to the extreme of durability, they were so sturdy that they did not suffer from such breakdowns, but the peeling off due to the feeling of use deteriorated its value, so there were many cases where only the outside was recolored and sold.
F4 is recolored by the method of plating.
Plating (meki) and painting (foil) are quite different.
In summary, plating is the coloration of metal materials, and painting is the coloration of plastic materials.
In order to prevent corrosion, plating is done by immersing the original metal material in an acidic chemical, removing all impurities to smooth the surface, applying color, and performing heat treatment.
It is not a single operation, but it is repeated several times to make it resistant to scratches. However, over the years, it reacts with the air surface, causing bubbles to form (found a lot in the Black Rollei series), and when scratched due to carelessness in use, it tends to become unsightly.
At this time, they are all decomposed again, soaked in chemicals, peeled off and painted again, and this is called plating (meki). (It is also a nogada term)
Painting is what gives the plastic a color. Also, since it is heat-treated in a special paint, it naturally melts into the plastic to give it a color. Unlike plating, painting is more difficult to recolor than plating because it penetrates.
Cameras made of brass before the 90's, and today's mid- and high-end aircraft (they use a lot of magnesium recently because they are light and strong) use plating, and popular devices such as Canon's 500D use plastic bodies and paint methods. .

The F4 was my first Nikon AF SLR. There are variations of F4S and F4E, but it's still heavy, but the battery grip seems to do something too cruel to my wrist. I got it with F4
