Featured Monday, 24 June 2013 22:51

Yourf2.8 lens does not deliver 100% of the light to your sensor... that is where the T Stop comes in.

    Very interesting stufff - but I like to know more about the consequences of light loss when you use different UV-filters. And also more on UV-filters and quality of the image......

    I'm using canon 70D, do i need to multiply the F/1.8 apenture by 1.6 crop factor? to get the exact apenture? because focal length is multiply by crop factor of APS-C camera.
