Walk through this. You get a cut and clean it appropriately, then cover it with triple antibiotic ointment. After a day or so, the wound and the surrounding skin get painful and red. Thinking your cut is infected you put more triple antibiotic ointment on it, which makes dermatitis worse.
The high quality, medium telephoto macro lens, has been developed for photographers who demand the highest level of optical quality. The new Hybrid IS system features up to 4-stop correction, compensating for the effects of camera shake, during normal shooting.
Pentax's classic manual lenses are very well regarded, by the way. The 50mm f/1.4 and f/1.7 are some of the best.
