Question 1

Is the Tamron 18-400mm discontinued?

Accepted Answer

Yes, the Tamron 18-400mm f/3.5-6.3 Di II VC HLD has been officially discontinued by Tamron. That makes the used market the main place to find one. Stock on the second-hand market turns over regularly, so it's worth setting up a search alert if you don't see your preferred condition grade available right now.

Question 2

Does the Tamron 18-400mm work on a full-frame Canon body?

Accepted Answer

The Tamron 18-400mm uses a Canon EF-S mount, which is designed for APS-C sensors. You can physically attach it to a full-frame Canon EF body, but you'll get heavy vignetting at wider focal lengths — Canon's own EF-S lenses behave the same way. For full-frame Canon DSLRs, this lens is not recommended. It's built for APS-C bodies like the Canon EOS 90D, Rebel series, and similar crop-sensor cameras.

Question 3

How does the Tamron 18-400mm compare to a Sigma superzoom?

Accepted Answer

The main practical advantage of the Tamron 18-400mm over competing Sigma superzooms is its broader focal range. The extra telephoto reach beyond 300mm gives you more optical compression and a bit more background separation at the long end — useful for wildlife or sports subjects at distance. Sigma superzooms in the same category typically stop at 300mm, so if maximum reach in a single lens is your priority, the Tamron has a clear edge.

Question 4

What Canon cameras is this lens compatible with?

Accepted Answer

The Tamron 18-400mm f/3.5-6.3 Di II VC HLD fits any Canon DSLR with an EF-S mount — that's any APS-C Canon EOS body. Common compatible cameras include the Canon EOS 90D, EOS 800D, EOS 850D, and the Rebel / Kiss series. It does not natively fit Canon EF-only full-frame bodies or Canon RF-mount mirrorless cameras without an adapter, and using it on full-frame bodies causes vignetting as noted above.

Question 5

Is the autofocus on the Tamron 18-400mm fast enough for sports and wildlife?

Accepted Answer

The autofocus is driven by a stepping motor — Tamron markets this under their HLD (High/Low torque-modulated Drive) branding. In practice it delivers reasonably quick and quiet focusing, which is fine for slower-moving wildlife, birds perched or in slow flight, and casual sports. For fast action like birds in rapid flight or motorsport, the AF won't keep up with dedicated telephoto primes or faster zoom options. Think of it as a capable everyday AF system — great for travel and casual wildlife, a compromise at the extreme end of action photography.

Question 6

What is the image stabilisation like on this lens?

Accepted Answer

Tamron's VC (Vibration Compensation) system is built into the lens itself, so it works regardless of which compatible Canon body you mount it on — useful on older bodies that lack in-body stabilisation. At 400mm on an APS-C sensor (giving roughly 640mm equivalent field of view), any stabilisation is welcome for handheld shooting. VC noticeably reduces camera shake in good light, though at 400mm you'll still want a reasonably fast shutter speed for sharp results on moving subjects.

Question 7

Is buying a used Tamron 18-400mm worth it?

Accepted Answer

For travel and all-round shooting on a Canon APS-C DSLR, a second-hand Tamron 18-400mm represents solid value. The lens was built for rugged use on the road, so used copies tend to hold up well mechanically. Since it has been discontinued, the used market is the only realistic way to get one. Every used copy sold through Camera-tweedehands.nl is professionally inspected, individually photographed, and covered by a minimum 12 months warranty — so the risk of buying second-hand here is low.

Question 8

How heavy is the Tamron 18-400mm 3.5 6.3, and is it practical for travel?

Accepted Answer

The Tamron 18-400mm weighs 710g, which is substantial but not extreme given the focal range it covers. To put it in context, carrying this single lens replaces a wide zoom plus a telephoto zoom, which together would likely weigh more and definitely take up more bag space. For one-lens travel where flexibility matters more than minimum weight, 710g is a reasonable trade-off. A peak-action wildlife shooter might find it heavy for extended handheld use at 400mm — a monopod helps significantly in those scenarios.
