عدسة Sigma 18-50mm f/2.8 DC DN Contemporary - متوافقة مع Canon RF مستعملة

I was blown away by how sharp this lens is at 18mm—it’s almost like a prime. The zoom ring feels smooth, and the f/2.8 aperture handled a dimly lit cafe without breaking a sweat.

I've been using this lens for event photography and the f/2.8 aperture really shines in low light, capturing sharp details even at wider angles. The zoom range is perfect for moving from group shots to portraits without swapping lenses constantly.

The f/2.8 aperture really pulls its weight in dim indoor shots, though the zoom ring feels a bit stiff right out of the box. It's clearly a used copy, but the optics are spotless and autofocus locks fast on my Canon RF body.
