No weather-seals -Focus ring rotates during autofocusĬanon’s own-brand EF-S 18-200mm superzoom lens is pretty ancient and lacking in telephoto reach. Although f/2.8 isn't a super fast aperture, image quality is excellent and it's a charming little prime lens for travelling light. Teeny tiny and extremely lightweight, this 'pancake' lens is less than an inch in length and only weighs 125g. Great-value option: Canon EF-S 24mm f/2.8 STM
Further good news is that the front element neither extends nor rotates during focusing. Meanwhile, autofocusing is fast due to the rear-focusing mechanism that drives the smaller, rear elements of the lens via a ring-type ultrasonic system. Sharpness is impressively good, even at the widest available aperture.
