SMC Pentax-F 300mm f/4.5 ED K 接環鏡頭 - 二手

I was nervous buying a used lens, but the autofocus snaps into focus faster than my newer kit lens. The image quality is stunningly sharp even wide open, and that 90-day warranty gave me peace of mind. Just wish the rubber issue was mentioned upfront, but for the price it's a steal.

The rubber peeling near the nameplate is a bit of an eyesore, but the glass is flawless and the autofocus is snappy even in low light. That 300mm reach with the ED element gives me tack-sharp wildlife shots every time, and the 90-day warranty made the used purchase a no-brainer.

I’ve been shooting with this lens for a few days, and the ED glass makes a noticeable difference in color and contrast—even at f/4.5 it’s sharp. The rubber on the nameplate is lifting a bit, but the glass is spotless and the 90-day warranty gives me peace of mind.
