Lens recommendations for EOS M50 and maybe a quick lesson about lenses

[Code-E]

Hi there,

 

So I have a Canon EOS M50 and the Canon EF 50mm F/1.8 STM lens, I'm really new to cameras that need lenses so I have no idea why this lens is SO zoomed in, at least compared to the kit lens that came with the M50. I'd like the blurred background that comes with the 50mm lens but a bit less zoomed in. I'm using the camera for video btw, the 50mm lens makes it so I can't use it in the recording space I have. It also seems to make the mic on the camera less effective because of the distance.

I've done some googling and can't figure out which of the aspects of the lenses, that I don't fully understand, is causing this zoom.

 

Thanks for any recommendations and any lessons.

you should do research about focal length, crop factor and how they affect field of view

a issue with switching to shorter or longer focal length on a lens (wider or narrower angle of view) affects also distortion and perspective of how you see something through the lens

The EOS M50 seems to use (at least from what I managed to find) an APS-C sensor, which has got a 1.6x crop factor.

Therefore, a 50mm lens on your M50 will act like an 80mm (50 x 1.6) would on a full frame camera.

50mm will be zoomed in compared to the 15-45mm kit.

Why people use it? for making portrait photos, to use it you stand as close as possible to the object to create a blurred background with the lens wide open at 1.8.

Oh so the sensor in the camera affects the zoom of the lens? I didn't realize that at all, tho I don't have a frame of reference for the difference of 80mm vs 50mm.

Is the F/1.8 tied to the 50mm(focal length?)

Because doesn't the F stop cause the blur behind the subject?

I guess I'm mostly wondering what lenses would keep the blur but be more usable in my space.

I found on B&H a lens that is 35mm and f/1.8 but says it's used for macro, so I'm not sure if it would work well for my use?

Well in your case, since you're using a prime lens, you don't have to worry about the lens having to stop down on its own. This is generally the case on cheaper (though it's not exclusive to cheap ones) zoom lenses.

For instance, take Canon's EF-S 55-250mm f/4-5.6 IS STM. At 55mm, wide open it'll shoot at f/4. Zoom it in to 250mm however, and it'll stop itself down to f/5.6.

The faster a lens (lower f-number), the shallower the depth of field.

Depends on what your use is. Macro lenses don't necessarily have to be used just for macro shooting - they tend to make solid portrait lenses too, for example.

sensor does not affect zoom of the lens it affects angle of view and depth of field

aperture size with related to focal length and focusing distance affects blur behind subjket

no idea what your space is

what's the lens on b and h?

 

take a course on basics of photography, you look like you need it

This is an approximation of the "zooming in" that you'll see using an APSC camera over a "full frame" camera with a full-frame lens (what is outside the black circle is outside of the field of view of the lens):

 

 

The black circle is the image circle projected by the lens into the camera body (what is outside of the circle is outside of the field of view of the lens). The sensor only gets the middle of the image circle projected onto it. The blue rectangle is about what a full-frame sensor would show as the image, the red rectangle is the equivalent of a cropped (or "APSC") sensor like in the M50. To get the same image on the red sensor as with the blue one, you would need to either use a wider-angle lens or walk backwards to get the same framing.

 

This also affects the depth of the focal plane (how much of the image is in focus). To get the same depth of focus on an APSC body you either need to use a wider aperture lens or change the distance between the camera and the object (the closer you get the thinner the focal plane gets).

I definitely need a photography/videography class of some kind lol this is more complicated than I originally thought

 

This is the lens I was talking about. I just looked for the first lens that was lower in focal length but also had F/1.8

I'm definitely understanding that what I was calling zoom seems to be the lenses field of view, which is affected by the crop of the sensor compared to a larger sensor.

So 50mm is fairly narrow field of view and a 20mm would be quite a bit wider?

 

The space I have is about 12 feet (like 3.5 meters), it's just my room. When I use the 50mm lens I have to have it on the opposite wall and it's really just my head and some of my shoulders

 

Edit: I'm also understanding that because of my particular sensor I have to add on the crop to know what a lens would be for me. 

Thanks for all the answers btw, I definitely would have taken a while to get that particular thing

actually its not complicated at lot of it is common sense and a basic understanding of physics

i learned photography in grade school and taught myself most of it

A human's natural field of view is approximately the same as the FoV from a 50mm lens on a full-frame camera (or a ~35mm lens on an APSC sensor).

[GDRRiley]

I'd grab the canon 22mm F2 lens its going to be a lot wider. (35mm FF)
