Is there a difference between taking a far shot on a 50mm lens and a close shot on a 35mm lens?

If you shoot from the same position with both lenses, then taking the 35mm lens and cropping it to the same angle of view of the 50mm lens will give you pretty much the same picture, other than the ...

Would it be possible to make a 36×36 mm "full frame" sensor?

That's not correct. Look at this picture: The green rectangle is a 36x24 sensor. The green circle, which has a diameter of 43.3mm, is the minimal light spot needed for that size. The blue square is ...

How is picture format related to sensor format resolution?

1/1.57″ is not a height/width ratio, but the diagonal of the sensor measured in inch. For some reason, camera manufacturers tend to define the sensor size as a fraction instead of simply writing 0.64″....

Is there a noticeable difference in image quality between Micro Four Thirds and APS-C entry-level DSLR cameras?

A great deal here depends on when you (generally) take pictures. In particular, with bright light, a smaller sensor makes little or no difference in quality. As the light level drops, however, a ...

Is there a noticeable difference in image quality between Micro Four Thirds and APS-C entry-level DSLR cameras?

In practice this is not a concern unless you have very demanding needs. Now I would preface this by saying that my view of "image quality" is that many people, particularly beginners, tend to make ...

I am getting a complete vignetting on my new canon 6D but only with the 18-270mm lens

From the "Recommended For" tab of the Tamron web page for that lens: Tamron Di-II lenses are engineered expressly for digital SLR cameras with image sensors commonly referred to as APS-C, measuring ...

focal length and sensor width of a phone

The Redmi 6A uses the Sony Exmor IMX486 sensor, which is a 1/2.9" format sensor. Note that "1/2.9 inch" is merely a name, not its diagonal dimension (see: Why is a 1" sensor ...

Would APS-C be better for shooting wildlife?

Crop sensors are indeed used for wildlife to get more reach without sacrificing megapixels. And, you can get closer images without spending as much money. Sure, you could crop, but then your printing ...

Do full frame sensors have a higher exposure?

The full frame sensor will not be brighter under the same exposure conditions (Same light in scene, same focal length and f-number, same exposure time, etc.). It will collect more light, but it will ...

Why do lenses for larger sensors tend to have shallower angles?

This is simply where the market is converging to at the moment. The typical kit lens is still 18-55mm on an APS-C sensor but most people find wider angle more useful, so some manufacturers made a few ...

Would it be possible to make a 36×36 mm "full frame" sensor?

Is it possible and why it has not been done yet ? Not necessarily. A 24x36mm sensor will easily fit in an image circle that's too small for a 36x36mm sensor. Specifically, a 24x36mm sensor requires a ...

Would APS-C be better for shooting wildlife?

Not necessarily. The APS-C sensor merely crops the image that would have been captured on a full frame sensor, so you end up with what you'd get if you used a full frame and cropped in post (see: ...

Is there a noticeable difference in image quality between Micro Four Thirds and APS-C entry-level DSLR cameras?

There is without a doubt a noticeable difference. The smaller sensor size, as you mentioned, gives a Micro Four-Thirds camera a disadvantage when it comes to low-light performance. The real question ...

Why did they ever make smaller than full-frame sensors?

Big sensors cost more than small sensors for more-or-less the same reason that big TVs cost more than small TVs. Compare a 30-inch TV and a 60-inch TV (about 75cm and 150cm, if you prefer). ...

No, f/stop does not vary with sensor size. Nor does focal length vary with sensor size. The lens remains totally unaffected by the sensor. HOWEVER, the field of view that the cropped sensor can ...

Is crop or full frame sensor best for macro work

For a given number of pixels, a crop sensor will indeed have a larger pixel density, thus a potentially larger resolution. But as the pixels are smaller, you'll have a bit more noise. The real ...
