Hi Mester, how can I get a specific focal length from this lens? For example, how can I get focal length=40 mm or 50 mm? please

the answer will be

focul length will be 27-88mm (35 mm equivalent). So , if I do not move the lens to enlarge the view. Is that mean the focal length will be 27 mm or not, please?

that is my enquiry

I’m sorry, I really don’t understand your question?   Are you wanting to know the full frame equivalent of your lens on crop?  If so, what lens and the bigger question is why?  There really isn’t all that much use for that information unless you are really used to 35mm values.   But in any case, take the focal length times 1.6 and you will get the ff equivalent of that same field of view
