Excerpt: And it is. Sharp, colourful, so much detail which you appreciate even more when you start to pull apart the raw and do post-processing - it really holds up. Aberrations of all sorts are excellently controlled.
Excerpt: Extremely well built, superb fit and finish. Color and contrast on the lens fit the bill for me, I haven't noticed any serious CA at all. Fit, finish and the design of the lens are superb. Weight is substantial at about 37 ounces and the lens is a tad over 7" long and with internal focus does not extend, a good thing. It is easy to handled and the balance of the lens on the K-3 is just right. I like the tripod collar configuration with the removable foot in particular.
Excerpt: Like another reviewer, I had been pretty happy with my 55-300. I purchased this lens with the 1.4 converter for birding. I don't know if I will look at my 55-300 photos the same. This lens puts my nature shots in another league.
Pros: Very sharp, well built, silent focus, reasonably compact
Excerpt: I purchased this lens brand new because I wanted the 1-yr warranty. As it turned out, I love it. The AF is very silent, I almost thought it was broken, but it is so fast and quiet. Colors are Pentax typical. Very sharp. It is only an f4, so it is not the fastest lens, so using a 1.4x TC may not be a bad thing with good light, but I normally do not use it. Wide open is sharp, so I only use it that way. In case of low light and/or with TC, the AF hunts a bit.
Pros: Silent AF, colors, sharp
Cons: AF hunts in low light or stopped down (same thing)- Tripod mount is too small.
Excerpt: I upgraded to this lens from a DA 55-300 an I will never look back to that lens again. Sometime I do have problems with the lens finding objects that are out of focus at the moment but then the quick shift helps me out. This is also the first SDM-lens I own and I love the silent mechanism!
Pros: The lens is sharp, produces a nice bokeh and has a nice quality feeling of metal to it.
Cons: The autofocus could be faster and more accurate
