Question 1

Is the Sigma 500mm f/4.5 EX APO DG HSM sharp at f/4.5?

Accepted Answer

Yes — image quality wide open at f/4.5 is very good, with strong colour and contrast. It's considered sharp by super-telephoto standards even before stopping down. The practical catch is that at 500mm and f/4.5, depth of field is razor thin, so precise focus is critical — a slight miss shows immediately in your shots.

Question 2

How does the Sigma 500mm f4.5 compare to the Canon 500mm f4?

Accepted Answer

The Canon EF 500mm f/4L IS USM has a half-stop advantage in aperture and includes image stabilisation, which matters a lot for handheld shooting. The Sigma 500mm f/4.5 lacks built-in stabilisation but historically sold for significantly less, making it a practical alternative for photographers who prioritise reach on a budget or who shoot from a stable platform like a hide or monopod.

Question 3

Can the Sigma 500mm f/4.5 EX APO DG be used with a teleconverter?

Accepted Answer

Yes, Sigma's own teleconverters are the safest pairing. A 1.4x converter brings you to roughly 700mm at f/6.3, which remains usable in good light. A 2x converter pushes you to 1000mm but at f/9, which will limit autofocus on many Canon bodies — check your camera body's AF sensitivity spec before relying on it.

Question 4

What Canon DSLR bodies is this lens compatible with?

Accepted Answer

The Canon EF mount means it works on every Canon EF-mount DSLR body — from entry-level Rebels through to the Canon EOS 7D Mark II and the Canon EOS 5D series. It does not natively fit Canon RF-mount mirrorless bodies without an EF-to-RF adapter.

Question 5

Is buying a used Sigma 500mm f/4.5 worth it?

Accepted Answer

For super-telephoto glass, the used market is one of the smartest ways to buy. These lenses are built to professional standards, so a well-kept second-hand copy performs identically to new. All used lenses on Camera-tweedehands.nl are professionally inspected and come with a minimum 12 months warranty, so you're not taking a blind risk.

Question 6

Is the Sigma 500mm f/4.5 EX APO DG HSM available in Nikon fit?

Accepted Answer

The Sigma 500mm f/4.5 EX APO DG HSM was produced in multiple mounts including Nikon F. If you're after the Nikon-fit version, search specifically for the Nikon-mount variant — the Canon EF listing won't autofocus on a Nikon body.
