Average Reviews:
(More customer reviews)I got this in the hopes of replacing both a Pentax 50-200 and a Sigma 70-300. Luckily, the image quality seems to be an improvement over both, though they were acceptable on their own. This lens is just a bit smaller than the Sigma, though not close to the small size of the 50-200.
The Pentax 55-300 does not have a quasi "macro" mode as do some other xx-300's including the Sigma, and the closest focusing distance is 4.67ft (1.4m) which is not particularly close, either.
As seems standard with Pentax, the lens hood has a hatch to allow turning a polarizer filter, and the "Quick Focus" ring allows manual focus to fine-tune the auto-focus when the shutter is still half-pressed.
Not particularly a fast focuser, it can hunt in low-contrast situations and when going from very close to very far, or occasionally lock up. The variable f4-5.8 speed is not great for low light but is is OK in most daylight circumstances and helps to keep the cost and size down.
Comes with front and rear caps, a black nylon pouch with no strap or loop, and a manual.
