Sony a6500 and lens crop factors

[gorillamotors]

I own a Sony a6500 APS-C camera. I know that if you put a full frame lens on it you need to multiply 1.50 crop factor. If you put on a APS-C lens on it do you still need to add the crop factor or not. ie Adding a Sony 24mm 1.8 APS-C lens. Does that make it a 24mm or a 36mm lens?

The crop factor applies to the real, physical FL 

of ALL lenses. Most lenses are marked with the 

real FL, so DO apply the factor when mentally 

figgering the field-of-view.  

    

----------------------------------------------------------  

 

The most frequent exception to marking lenses

with their actual real FL occurs with megazoom 

bridge cameras, which in its own way makes a 

lotta sense, given that the built-in lens cannot 

be interchanged Zoom rings on such cameras 

may typically be marked "24 ~ 600mm", even  

tho their real FL range is 4.5 ~ 110m .... cuz a 

user of such a camera is innerested only in 

know the field of view, not being free to choose 

other lenses for it.
