It's a good lens considering the price , great reach but because of the fact that it's a 400mm and f/5.6 , you need to shoot in good sunny weather conditions to be safe in regards to speed and aperture without having to go too high in ISO.
Here you will find some pictures i just made in bad weather conditions , i often pushed the ISO to 3200 to get at least 1/200s at 400mm , i have a Pentax k-x therefore the results are very good , i would say that this lens would be perfect combined with the new K-5 which seems to have excellent high ISO performance.
At the same time you can compare the difference in reach 120mm-250mm-300mm and 400mm

I don't agree , it's ok at f/5.6 but i think most people like I will use this lens around f/8.
Musn't forget it's very low price

I like these. Sometimes you don't want a razor sharp lens. I get so mad when sharpness is all a lens is judged on. These are very good hand held photos. I hope you have a lifetime of enjoyment with it.

Bokeh? I tend to want razor sharp lenses because of the subjects i shoot but a good bokeh and or contrast can be just as or more important for other subjects.

sometimes with modern dslr high megapixel counts combined with a razor sharp lens when used for portraits it can be unflattering - every wrinkle and crease every dimple and capillary and you end up having to blur things abit in photoshop to make the subject look like they do to the human eye
