I have quite a trouble adjusting with this lens. I just got it today. Please share your experience with me, so I can determine whether the problem is me or the lens.
I have only test it few hours, and it's already nite in here. I use available room light and the viewfinder looks dark, the result pics also until I bump to ISO 800 on my K100D. I got many foggy/blurry/white images at F4, yet the glass seems to be free from haze/fog, even dust or fungus. I tried it's max magnification (1:2?) and then move a bit back, 20-30 cm from the subject, looks the same. When I'm at F8 however it looks sharper, must be because of the fog is no more. The reviews said that this lens is, well, is always sharp at any aperture.
All with 0.10 sec. - ISO 800
F4
F8

So, what Am I missing here? Is this lens is more a 'under the sun' lens? Is it the character of this lens, or just another bad copy that I have to return?
ADDED:
- Shots are taken handheld.
- I use a combination of Fluorescent and bulb lamp in my room.
