Sony E-mount SEL20TC (2X Teleconverter) Rental in Japan

Product Summary:

The Sony SEL20TC 2X Teleconverter is a high-magnification accessory for full-frame photographers in Japan seeking maximum reach with their compatible E-mount telephoto lenses. This teleconverter doubles the focal length of the attached lens by a factor of 2.0x, effectively turning a 70-200mm lens into a 140-400mm lens, or a 400mm lens into an 800mm lens.

It is designed to be dust and moisture-resistant for robust outdoor use. The teleconverter operates with a corresponding light intensity reduction of two F-stops.

Quick Highlights:

• Extends the focal length of compatible lenses by 2.0x (doubles the reach).
• Ideal for extreme magnification for distant wildlife and sports.
• Light loss of two F-stops (e.g., F2.8 becomes F5.6).
• Designed to be dust and moisture-resistant.
• Maintains high image quality and full autofocus/auto exposure functionality with compatible lenses.

Product Details / Description:

For serious birding, distant nature photography, or capturing action from the sidelines during your visit to Japan, the Sony SEL20TC 2X Teleconverter delivers extreme telephoto capabilities while minimizing the weight and size of your overall kit compared to carrying an enormous native super-telephoto lens.

About the Product

The SEL20TC features an optical construction of 8 elements in 5 groups, specifically designed to mitigate the increased aberrations that come with high magnification and to preserve the high resolution and contrast of the primary lens.

Important Compatibility Note: Similar to the 1.4X teleconverter, the SEL20TC has a deeply protruding front element, making it physically incompatible with many lenses. Incompatible lenses, such as the SEL70200G (FE 70-200mm F4 G OSS) and the LA-EA4 mount adapter, cannot be used as the rear element of the teleconverter would make contact and cause damage. Always verify compatibility on the official Sony compatibility list before use.

Key Features

• Full Automation: Maintains communication for AF, AE (Auto Exposure), and OSS (Optical SteadyShot) with compatible lenses.
• Professional Use: Excellent accessory for extending the reach of high-end G Master (GM) lenses.

Faqs:

What is the trade-off when using the 2X Teleconverter?

The main trade-off is the two F-stop reduction in light intensity. For example, a fast F2.8 lens becomes F5.6, and an F4 lens becomes F8. This requires either slower shutter speeds or higher ISO settings, which can affect image quality in low light.

Why is the SEL70200G (FE 70-200mm F4 G OSS) incompatible with the SEL20TC?

The incompatibility is due to the physical design; the teleconverter’s front element protrudes significantly and will physically collide with the rear element of the SEL70200G or the LA-EA4 mount adapter, causing damage.

Does the 2X Teleconverter still allow autofocus (AF) to function?

Yes, with compatible lenses, the full AF function is maintained. However, because the lens’s maximum aperture is reduced by two stops (e.g., F8 max aperture), AF performance may be degraded or slower in very low light compared to using the lens alone.

How does the lens construction (8 elements in 5 groups) maintain image quality?

To double the focal length, the teleconverter needs to be a complex optical system to correct for aberrations introduced by the extra magnification. The use of 8 elements ensures that key image qualities like sharpness, contrast, and color fidelity are preserved at a high level.

What happens if I attach an incompatible lens or accessory?

If you attach an incompatible lens or accessory, the camera body will not recognize the lens and the aperture display will show “–“, indicating that AF (Autofocus) and AE (Auto Exposure) will not function.
