Nikon AF-S Teleconverter TC800-1.25E ED 1.25X

A modest reach boost for select Nikon super-telephotos

The TC800-1.25E ED is a purpose-built teleconverter engineered for select Nikon AF-S super-telephoto lenses, adding 1.25x magnification without the bulk or compromise of a general-purpose adapter. Its ED glass element is there specifically to control the chromatic aberration that longer effective focal lengths tend to introduce, keeping the optical formula of the host lens intact than fighting against it.

This is a converter built around compatibility, not generic reach. Because it's matched to specific AF-S super-telephoto optics, it slots into the existing autofocus and aperture communication of those lenses than acting as an universal add-on. For shooters already invested in Nikon's F-mount super-telephoto lineup, that means a straightforward way to stretch a given lens's field of view without swapping to a different focal length entirely.

It's a specialist's accessory: small, focused, and meant to live in the bag of someone who already owns the specific glass it's designed for. For that shooter, it's a direct, uncomplicated way to squeeze more reach out of gear they've already committed to.

Who It's For

Wildlife photographers running a compatible Nikon AF-S super-telephoto lens gain extra reach at 1.25x without changing lenses mid-shoot, useful when a subject won't close the distance. Bird photographers benefit the same way, since the ED glass element is built to manage the chromatic aberration that comes with extending focal length than degrading the image. Sports shooters working from a fixed sideline position, who need a bit more focal length without a bigger lens, get a compact way to adjust framing on the fly. Anyone already committed to Nikon's F-mount super-telephoto system will find this a targeted way to extend what that glass can already do.

FAQ

What lenses is the TC800-1.25E ED designed to work with?

It's built for select Nikon AF-S super-telephoto lenses. Because it's engineered for specific optics rather than general use, it integrates directly into the autofocus and aperture communication of compatible glass - check Nikon's compatibility list to confirm your lens works with it.

Why does this teleconverter have an ED glass element?

The ED element controls chromatic aberration that comes with longer effective focal lengths. Rather than fighting the host lens's optical formula, it keeps the original design intact while stretching the field of view.

Does the TC800-1.25E ED work with autofocus?

Yes. Because it's matched to specific AF-S super-telephoto optics, it maintains the autofocus and aperture communication of those lenses - you don't lose AF functionality the way you might with a universal converter.

How much bulk does adding this converter add to my setup?

It's small and focused. It's meant to live in your bag as a backup reach option without significantly changing your kit's footprint or weight.

What's the practical advantage of 1.25x magnification over buying a longer lens?

You stretch reach on glass you already own without committing to a different focal length or swapping lenses. It's a way to squeeze more from an existing investment.

Can I use this teleconverter on general-purpose telephoto lenses?

No. It's engineered specifically for select AF-S super-telephoto lenses, not for universal use across the Nikon F-mount lineup.
