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 ...

So my iPhone 6 camera lens is as wide as my full frame 35mm DSLR lens?

You're right that the angle of view of the iPhone camera is a little bit wider than a 35mm lens on a full-frame film camera. Up until this point, you're not really confused. But the part after that, ...

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 ...

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 ...

How can a super tiny iPhone 6 Plus lens produce significant DOF?

Many older or cheaper phone cameras use a "fixed focus" lens. ie it is always set to focus a specific distance away from the camera. This is usually set to the "hyperfocal distance", ie everything ...

Is there a "special look" to images from large sensors that can't be replicated with a smaller one?

Many of the frequently touted reasons for larger sensors producing better images, more subject isolation, lower noise, better dynamic range, all assume you keep the f-stop constant, i.e. you use f/2.8 ...

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: ...

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 ...
