Does this make sense?
Yes, it makes sense. Things to add would be that this is a comparison of the field of view and the specific crop factor that is being applied.
Muy bueno Sparky! I really hope this helps clear up all the confusion that the forums have been seeing as of late
Similar photos/diagrams have been available on the net for years...and yet the confusion remains. I do hope it helps...but someone people just seem to want to be confused.
Nice, clear diagram, but the captions are a little confusing. What you are showing as the 'field of view' should be the 'image circle' shouldn't it? The field of view is defined by a combination of the format and the lens, it is not defined solely by the lens (ie the fields of view are the rectangles - they would only be the circles if the lens' image circle was smaller than the format, which is not the case here). The image circle is a property of the lens and only the lens.
(Keith - KmH - has a diagram that uses the correct terminology)
So change FOV to something like "Scene projected by __ lens"?
I think it's precisely the case here..... using a crop lens on a full sensor will not fill it, thereby affecting the FOV
Which I think the diagram shows... regardless of which sensor is used, the image circle remains the same.
Maybe I should have been clearer:
The circles in your diagram (marked as 'fields of view') are not 'fields of view', they are 'image circles'.
The rectangles in your diagram are 'fields of view'.
Now, Now, I thought I had it at last but there you go again confusing me :lmao:
It's easy! The circles are the image that the lens refracts(right word here?), the squares are what each sized sensor actually captures.
lol, I understand, it was a joke with all that chat with Helen,, Thank You much
I fixed it for you.
