Lens brightness and image stabilizer
The lens brightness and aperture value is f/2,8-4.
The lens is to considered fairly bright. This will make it so much easier shooting in darker environments where you do not want or can use flash lighting, for example in churches or at different sports venues.
One thing to consider is that the lens has a variable brightness, which means that depending on how much you are zooming the lens will have a different maximum aperture value. At 28 mm the lens brightness is f/2,8 and at 70 mm the brightness is f/4. Through the link below you can read more about what this could mean for you as a photographer.
The lens lacks image stabilization, which otherwise os good for avoiding the blur that can occur when using slow shutter speeds.

Filter and Lens Hood
The lens has a traditional filter thread on the front and its measuring 58 mm which also the filter you will use must have. If you use for example an UV filter can be a cheap insurance against scratches and dust.
Together with the lens there is a lens hood included but we have unfortunately no further information on model etc so feel free to contact us if you know more.
