Shooting: Images shot at close distance have a wider angle of view. Is this a malfunction? When I use a macro lens (60mm, 90mm, 180mm etc.), the maximum aperture value displayed on the camera is smaller than designated on the lens. Is this abnormal? When I point an all-in-one zoom lens (18-270mm, 28-300mm etc.) downwards, the lens barrel extends. What should I do? Flaws (dusts or blemishes or shadows) are appearing on my photos. Are they caused by the lens?
VC: Is it possible to use the Vibration Compensation (VC) mechanism when the camera is fixed on a tripod? The display in the viewfinder shakes when I start or end the Vibration Compensation (VC) mechanism. Is this abnormal? Can the Vibration Compensation (VC) mechanism be used for panning?

FAQs (Frequently Asked Questions)

Is there a difference between the "Macro" written on macro lenses (60mm, 90mm, 180mm etc.) and the "Macro" written on zoom lenses?: Tamron applied "Macro" to all lenses released up until 2009 that had close-up capabilities of a maximum magnification ratio of 1:4 (x0.25). However, there is definitely a difference in the design concepts of macro and zoom lenses with regard to close-up shooting. The design of macro lenses is ultimately geared towards the image quality and bokeh quality of close-up shooting, while still delivering adequate performance in general shooting (portraits, landscapes etc.). However, zoom lenses with macro capability are geared towards the image quality of general shooting, while still enabling easy close-up shooting with their macro capability.
For lenses released from 2010 onwards (Models A005 and B008), "Macro" will only be applied to lenses with a maximum magnification ratio of 1:1 (x1).
