Excerpt: The reviews of this lens were one of the big things that convinced me to go Pentax. The lens is plenty sharp for its price range, and light enough to shoot one handed. This is the lens I've got on my camera more than any other because its range is so versatile. Its great for walking around the park because you can get everything from distant animals to right up close insects. For example, the FA*300 cannot focus anywhere near as closely as this lens can.
Excerpt: I bought this zoom lens 3 years ago and still love it. It was in my first trip with my old K110D, and I must say I had no idea about zooms. I was looking for a 300mm as my goal was to use it in race tracks, and outdoors to take pictures of race cars. Once in NYC we've found that shop and well, I ended up buying it.
Excerpt: You really can't beat the value for what this zoom can do. I normally have a strange prejudice against zooms, but have no issues using this is my only long lens when I go out on hikes. Others have said that the IQ and sharpness suffer when shooting wider than f/8... I'll let the images speak for themselves. Besides that, the manual focus isn't the smoothest, the AF is kinda loud - esp if its hunting for an object that is hard to focus on.
Pros: Great bokeh possible, low price, great sharpness
Summary: I have the Pentax SMCP-A Zoom 80-200mm f/4.7-5.6 Lens but was considering buying this lens to get more zoom for wildlife photography. Luckily I tried it at a camera store and compared this lens to my existing lens. This lens (Pentax - SMC-P DA -L 55-300/4-5.8 ED Telephoto Zoom Lens For Digital SLRs) had significant image quality, contrast and color accuracy issues and I would not recommend it.
Excerpt: This is a pretty good lens, It can actually produce some pleasing bokeh if you know where to find it. I bought it so I could have the complete range from 18mm all the way to 300mm just in case I needed it. It's cheap and sort of feels cheap but the glass is very good for the price, it has great color and contrast. I highly recommend this lens if you are on a budget.
Pros: Great color/contrast, fairly sharp, good range
Excerpt: My quick take. The lens is light, small with great range. It is very well made with two exceptions; the cheap thin hood and the loose focus ring. Some purple fringing and aberrations, but not a big deal. Focus can be fast, but sometimes it can go through the whole range causing you to miss moving objects like birds ( oh if only it had a shorter focus throw and a DC motor!). Manual focus is fine despite the loose ring. Manual override after focus lock is a great feature.
