The distance from the center of the lens to the image focal point (=image sensor surface) is known as the focal length. It is expressed in millimeter (mm) units. A lens with a short focal length is a wide-angle lens and one with a long focal length is a telephoto lens.

Even if the focal lengths of the lenses of two digital cameras are the same, the angle of view can vary depending on the size of the image sensor used in each. To make it easier to understand angle of view, focal length is often expressed as "__ mm equivalent," which means it has been converted to the 35 mm film camera format that has been historically the most common. Here on this site also, we state focal lengths that are converted into 35 mm film camera format.

With a zoom lens, when you turn on macro mode and move as close as possible while still keeping the subject in focus, the minimum distance to the subject and the size of the subject in the frame will differ depending on whether the lens is at a wide-angle or telephoto zoom position. With a wide-angle setting you may be too close and with a telephoto setting you may be too far away so adjust the focal length to find the one that makes it easiest to take the shots you want.

The angle indicating the width of the field included in the photo is called the "angle of view." A wide-angle lens has a wide angle of view and a telephoto lens has a narrow angle of view.

Stress can induce modifications in the central nervous(CNS), autonomic nervous and neuroendocrine system. Thus, the stress response has long been measured in laboratory experiments by biochemical changes in the hormone systems that are referred to as the sympathetic nervous system(SNS) and pituitary-adrenocortical axes(HPA). These axes react to acute stress or chronic stress. The activation of these two particular pathways result in elevated serum levels of catecholamines, cortisol, ACTH, dopamine, and others hormones. But there is considerable debate about the relevance of traditional laboratory stress findings to real-life situation. The neurobiology of stress is a key step to the understanding of stress-induced changes of immune functions. The immune system operates in communication with brain and endocrine system. Because of this extensive communication, the immune system can influence how we feel and behave. The stress are associated with endocrine and autonomic changes that can inhibit immune system function. The concept of neurocardiology renders plausible the various theoretical constructs of stress as they relate to circulatory vascular disease. Detailed reviews of the anatomic connections between the brain and the heart and of experimental and clinical data on the role of the CNS in cardiac dysfunction can be found elsewhere. In this study, we reviewed that stress was associated with cardiovascular disease mortality through the known cardiovascular risk factors(hypertension, heart rate variability, homocycteine, and clotting system).
