Features of super telephoto lens

The higher the performance, the heavier the body and the higher the price of the super-telephoto lens. Since there is a peculiar habit in use, the key to selecting a product is to first find a model with the minimum necessary functions by comparing the performance and features you need. From here, let’s take a closer look at the features of such a super-telephoto lens.

Can shoot far away

The telephoto lens of the “large ternary lens” manufactured by the lens manufacturer with all its might has a focal length of about 200 mm. It is a standard distance for a telephoto lens because it allows you to take pictures of subjects that you cannot approach (close to), such as taking pictures of children participating in athletic meet or school festival, or aiming at animals in a zoo. On the other hand, the super-telephoto lens can shoot subjects farther than the telephoto lens of the large ternary lens, such as wild birds in the distance, trains running in the mountains, and aircraft in the sky. You can even take pictures of birds tens of meters away and aircraft a few kilometers away.

Zoom function

Many super-telephoto lenses have a zoom function. For example, Sony’s FE 200-600mm F5.6-6.3 G OSS SEL200600G covers a focal length of 200mm to 600mm with a single lens. You can freely change the distance to the subject with a single lens operation, such as 200 mm to 300 mm if you want to shoot a child running in the playground from the audience seat of the athletic meet, or 600 mm if you want to shoot a small wild bird that stays on a branch several meters away.

Single focus lenses that do not have a zoom function generally have advantages over zoom lenses, such as image quality, brightness, and lightness. However, the focal length is fixed. The distance to the subject must be adjusted by the cameraman himself.

Unique expressiveness

The angle of view of a photo taken with a super-telephoto lens is narrow. Naturally, the subject is boldly cut out and projected in a large size, creating the power unique to super-telephoto. Also, because the depth of field is shallow, the bokeh is dramatic. From this point as well, the presence of the subject becomes stronger.

Compression effect

Another feature of super-telephoto lenses is that you can capture a subject that is actually far away, such as an aircraft that is maintained far away from the airport or a train that runs on the mountain surface , as if you were close to it. Also, when the foot race of the athletic meet is taken from the goal position, the distance between the leading runner and the children running behind is much closer than the actual distance in the image. A “compression effect” that increases the power of composition and scenery is created, which helps to create images.

Correlation of size, weight and price

In general, the longer the focal length of a lens, the larger and heavier the product. This is because the number of blades, the number of parts, and the amount of material that make up the lens increase, and the amount of lens extension (extension during zooming) during focusing becomes longer. When it comes to 600mm super-telephoto lenses, it is not uncommon for models to weigh more than 3kg.

Furthermore, if you choose a lens with a small F-number (high performance) that determines brightness and bokeh, the price will rise further. For example, Canon’s EF 600mm F4L IS II USM costs more than 1.37 million yen, which increases the financial burden.

Strengths that differ depending on the manufacturer

Each manufacturer has its own strengths, as each lens has different characteristics. For example, Canon has autofocus speed and quietness. The highest quality L lenses are just professional lenses. Since Nikon has not changed the lens mount (the joint between the body and the lens) for a long time, there are many lenses that can be used in active use, from old types to the latest models, and the accuracy of focus and the robustness of the product are also strong points. SONY is good at capturing moving subjects perfectly, and has a reputation for its stylish design. In addition, SIGMA and TAMRON, which had been bundled with third parties until a long time ago, have improved the quality of their products, and now they have the same performance as genuine lenses and at a reasonable price. We are also active in developing models that cover niche focal lengths and performance / functions, and support photographers who are particular about shooting situations.
