Gebrauchtes Sigma AF 10-20mm F4-5.6 EX DC HSM Objektiv - Canon Anschluss

The autofocus on this used Sigma is surprisingly quick, and the 10-20mm range gives me exactly the sweeping landscapes I wanted. One tiny scratch on the barrel doesn't affect image quality at all.

Honestly, I was nervous buying a used lens, but this one is optically spotless and the autofocus locks on faster than my kit lens ever did. The 10-20mm range makes my interior shots feel cavernous, and the sharpness wide open is genuinely impressive.

Shot my first real estate job with this 10-20mm and the wide angle is just insane for interiors, every room looks twice as big. For a used lens the glass is still crisp at the edges, and the autofocus locked on without hunting even in that dim hallway.
