Pay attention to the details of buying used old lenses

As we all know, the camera was just the threshold into taking photos, and the lens was the bottomless pit we encountered after entering the door. Although modern fully automatic lenses are good, but also know that the functions they can provide are not necessarily what we need every time, but their price is out of reach. Then the manual lens in the past has naturally become one of our choices. If we are lucky, we can find a very good old lens.

And a good looking lens can last for many, many years.

So, what problems should we pay attention to when we go to the photographic equipment city to select old lenses?

First of all, the general eye view product phase, do not believe the seller to describe the so-called xx into a new, if this description can be believed, the camera can grow wings flutter flutter takeoff heaven. I’m not a beauty addict, I’m more interested in testing, so I don’t care if the lens has some test marks or some paint peeling on the outside, as long as the lens is fine, and the appearance of the battle will probably be cheaper.

But must see the lens, manual lens have aperture ring, when we looked at the aperture on the ring, and then focuses on the light, check if there is any dust or mouldy inside, little dust fair to accept, and for many old lens cannot avoid, but if you see hyphae will pay attention to, mould is contagious, If we don’t take care of it soon, this lens is going to die.

The coating on the surface of the lens is very important, it will directly affect the play of the lens, we should pay attention to whether the coating on the surface of the front and rear lens is worn when checking the lens, if the whole is complete, the coating is integrated, then the maintenance of the lens is good. Even a slight scratch doesn’t look too big for imaging, but it can be uncomfortable for a perfectionist.

After checking the lens, it is time to check the mechanical properties of the lens. Generally speaking, there are two rings on the old lens, the aperture ring and the focus ring. If it is a zoom lens, there will be a zoom ring. For the focus ring and the zoom ring, we’re going to rotate them to see if the damping is good, if there’s any difficulty in turning them, because manual focus can be a problem if the focus ring is dry or too smooth.
