Lens Overview — Opteka 650-1300mm

The Opteka 650-1300mm f/8 Super Telephoto Zoom Lens is a manual focus lens covering an expansive focal length range from 650mm to 1300mm, designed for full-frame cameras and mounted via the universal T-Mount system. With a T-Mount interface, this lens can be adapted to a wide variety of camera systems using readily available T-mount adapters, making it a flexible option for photographers who shoot across different platforms. The lens covers the full-frame format, so no crop factor concerns arise when used on a full-frame body.

At a maximum aperture of f/8 across its range, light transmission is modest, which is typical for lenses operating at these extreme focal lengths. The lens is entirely manual focus, meaning autofocus is not supported — a consideration worth weighing depending on your shooting style and subject matter. Image stabilization is not present, so a sturdy tripod or support system is strongly recommended given the focal length range.

Weighing 2000g, the lens has a substantial physical presence. The 95mm filter thread accommodates large-diameter filters. This is a zoom lens spanning the super telephoto category, suited to wildlife, astronomy, and distant subject photography where extreme reach is the primary requirement.

Description — Opteka 650-1300mm

The Opteka 650-1300mm Super Telephoto Zoom Lens brings extreme reach to photographers working with full-frame cameras via a universal T-Mount interface. Spanning a focal length range of 650mm to 1300mm, this zoom lens sits firmly in the super telephoto category and is built for subjects at significant distances. The lens operates at a maximum aperture of f/8 and is a manual focus design with no autofocus capability, requiring the photographer to focus by hand. Image stabilization is not included, making a tripod or equivalent support critical for sharp results at these focal lengths.

The 95mm filter thread at the front of the lens accommodates large-format filters. At 2000g, this is a substantial piece of glass that demands a capable support system. Because it uses the T-Mount system, it can be adapted to a variety of camera platforms using the appropriate mount-specific adapter, giving it broad compatibility across interchangeable lens camera systems.

Frequently Asked Questions — Opteka 650-1300mm

What cameras is this lens compatible with?+
This lens uses a T-Mount interface and is compatible with various camera systems via T-mount adapters, as noted in the specifications. You will need to purchase the appropriate T-mount adapter for your specific camera brand separately. The lens itself does not lock into any proprietary mount without an adapter.
Does this lens cover full-frame sensors?+
Yes, the lens format is specified as Full Frame, meaning it is designed to cover full-frame camera sensors without vignetting. It can also be used on crop-sensor cameras with the appropriate T-mount adapter.
Does this lens have autofocus or image stabilization?+
No. The specifications confirm that autofocus is not available — focus is entirely manual. Image stabilization is also listed as None, so a stable tripod or support system is strongly recommended when shooting at these focal lengths.
What is the maximum aperture of this lens?+
The maximum aperture is f/8 across the zoom range. This is a relatively narrow maximum aperture, so adequate lighting or higher ISO settings on your camera body will be important for achieving proper exposure.
What filter size does this lens accept?+
The lens has a 95mm filter thread, which is a large diameter. Filters of this size can be more expensive and less commonly available than smaller sizes, so factor that into your accessory planning.
How heavy is this lens?+
The lens weighs 2000g according to the specifications. Given this weight combined with the extreme focal length range, a robust tripod head rated for this load is highly advisable for comfortable and stable shooting.
