However, buying the lens course not exactly cheap, especially for you who have a budget mediocre. An alternative you can do is buy used photographic equipment, because used lenses certainly have a lower price than new lenses. However, when deciding to buy a used lens, you are required to be more careful so as not to buy the wrong one. Below are some tips for you who want to buy a used lens.
1. Do you want to buy online ? When buying online, make sure that the online store has a good track record. Likewise, when you buy lenses in a shop not online, you also have to recheck how the quality and reputation of the shop and shop owner – where you can find out in advance about the price of their products and services.
2. Open the lens aperture at the largest opening in each lens. Each camera brand is different, you name it Nikon, which you can do by sliding the aperture lever on the back of the lens. However, for Canon it will automatically open when it is not mounted on the camera. When the aperture is open, aim the lens in front of a lamp or bright place if you want to see no / no dirt or mildew.
3. Point the lens towards the lamp or use a small flashlight to see if there is scratch on the lens. You can move it in front of the back so that you will see the shadow of the lens elements inside.
4. If there are lights, gently rotate the lens and look inside the lens. Check for loose parts or loose lens components. To check that there is an unusual noise, then put the lens in the ear.
5. Check the lens mounting mechanics. Make sure that none of the back of the lens is cracked, broken or missing.
6. Then check the thread ( thread ) for the filter in the lens. Make sure the thread is still perfect because if there is a dent ( dent ), most likely you will not be able to use filters. Try installing a filter in that section. There are used lenses that are sold in a filter attached state and usually the filter is rather difficult to open. If you find a case like that, don’t force open the filter because it will damage the lens. All you can do is make sure the thread in the filter is installed in a good condition so that you can install a new filter later.
7. Make sure the hood is in good condition and can be installed perfectly.
8. Intend to buy a zoom lens ? Be sure to check all focal lengths from small to large and vice versa. Make sure there are no strange sounds and zooming can be done smoothly, not faltered, or not too weak.
9. Check the focus ring by turning it and pay attention as well as when you check the zoom in point 8.
10. Mount the lens when you have checked the points above. Make sure that the process runs perfectly and safely, even if you try to unmount the lens.
11. Take photos using the largest and smallest aperture at all focal lengths , whether auto focus works well or not.
12. Use the newspaper then test the photo several times to make sure the lens does not misfocus and know the sharpness of the lens. Also keep in mind that each lens has a different sharpness, so don’t match all lenses that have the same sharpness.
13. If the lens has a VR ( Vibration Reduction ) or IS ( Image Stabilization ) feature or other similar feature, make sure the feature still works well. Set a camera with a low shutter speed then test photos with these features active and inactive. See if there is a difference.
14. When viewing a lens ad that you will buy, there are usually other equipment. Don’t forget to note what completeness is provided, for example boxes, boxes, manuals, pouches , front & back covers , hoods , or tripod collars .
15. Finally, when buying photography equipment, it is also important to make sure whether there is a guarantee or not. Before you make a transaction, make sure whether or not there is a warranty provided in the purchase of the lens. If so, how long and for what conditions. Then if possible, ask for a receipt as proof of transaction, to make it easier for you to know the record history of each lens you have.
Used or new, whose name is photographic equipment is still not cheap. Therefore, it is very important to take care of him. Especially if you buy it from your own savings, of course it will feel more valuable. Good care will make you more efficient, because the usefulness of your photographic equipment will be more durable and long lasting.
