I saw a video on YouTube, that using this formula I could find out which lens (supposedly) will blur the background more. I know it depends on several factors. but the formula would be for example a 105mm lens ÷1.4F = 75 135mm÷1.8F= 75 If I have the subject in the same composition the blur the same?
