Diagonally it s 35 degrees.
35mm full frame lens on crop sensor.
Crop sensors are smaller than full frame sensors.
A 28mm lens on a camera with a crop factor of 1 3x has a 35mm equivalent of 36mm.
When you mount a full frame lens on a camera with an aps c sensor you will get what is called a crop factor.
30mm x 1 6 48mm.
Does image size change using a full frame lens on an aps c body.
So on full frame sensors 50mm and 35mm lenses perform exactly as you d expect as 50mm and 35mm lenses.
In fact full frame refers to the frame size of 35mm film.
Which means that on a crop sensor camera the lens focal length is effectively magnified.
But on crop sensor cameras the effective focal length of these lenses is increased.
If you mount the same lens to a camera with a full frame sensor vs one with a super 35 sensor the super 35 camera will give you an image that is 1 5x optically zoomed in.
30mm conditionally turns into 45mm or 48mm on canon 30mm x 1 5 45mm.
A 35mm lens on a camera with a crop factor of 1 3x has a 35mm equivalent of 46mm.
It is with these on crop sensors we get a field of view similar to the 50mm.
Take a look at a 70mm lens.
A 24mm focal length lens will have the equivalency of 36mm.
If you want a good wide angle lens for a crop sensor check out the tokina f 2 8 11 16 mm.
It takes the 35mm full frame sensor as a standard and the viewing angles various lenses produce on it.
There are great lenses on the market that offer this focal length for aps c sensor cameras the 30 35mm prime.
The respective image size is always tied to the sensor.
On a full frame sensor its viewing angle is 29 degrees horizontally and 19 5 degrees vertically.
So the two phrases can be considered the same.
Those beloved nifty fifty 50mm lenses are now 75mm lenses and so on.
A 35mm focal point on a full frame sensor will appear 1 5x larger than a 35mm focal point on an aps c sensor this is the crop factor.
