Once a photographer or cameraman comprehends lens adapters and lens mount adapters in general, it’s vital to know why they are required. Here are a few reasons photographers and camera operators use lens and mount adapters.
Upgrading a Camera
When upgrading to a fresher or more innovative camera within the same brand, you should be aware that camera makers do occasionally change the mounting systems they use for their lenses, so using older lenses with the fresh camera may necessitate the use of an adapter.
Swapping to a Camera from a Different company
If a photographer has been shooting with a Canon for years and then switches to a Nikon, the lenses that were bought for the original camera will not be compatible with the next. This is because every camera brand has slightly changed specs, and obviously, firms make lenses that fit their own gear. Not only may the mounting arrangements be dissimilar, but the actual lens sizes will probably differ as well.
Using Cheaper Lenses
A photographer who is trying to be economical may want to capitalise on a top of the range camera but may not then have the extra cash to buy a group of new lenses from the same firm. Such a person might then be drawn in purchasing new or used lenses from other lens producers, which will probably not be compatible with the camera. A lens plus an adapter may, in many cases, cost less than acquiring the matching brand of lens.
Trying out Macro Photography
Macro photography is the art of taking extreme close-ups pictures of very small things so that the photo images are many times larger than real size. Instances of subjects are things like insects, plants, and anything else nature has to offer. Distinct macro lenses are fashioned for this purpose, and an adapter may be required if the lens, as mentioned, is made by a different company than the camera itself. However, a cheap trick is to invert the prime lens on the camera by mounting it back to front, which will let you to try some macro photography without having to splash out on an additional lens that may not get a lot of use anyway. While the reverse mounting method will not give the same results as a specialized macro lens, it is suitable for experimentation at least. To do a reverse mount, an adapter will be needed of course.
Another valuable adapter for reverse-mount macro photography is a one that allows a filter to be screwed onto the inside of the lens (which is now actually the outside instead). This is occasionally called a bayonet-to-standard thread adapter. Since exposing the inside of the lens will make it susceptible to getting dirty, which can really impact the quality the images you create, it’s a good idea to attach a cheaper protective filter, such as a UV one, for the sole reason of protection.
