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 ...

Why are large zoom ratio constant apertures lenses not generally available?

The main reason we don't have "super zooms" with a large constant aperture is size/weight/costs. Roger at LensRentals recently blogged about this in the post: About That 25-300mm f/2.8 You Wanted ...

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 ...

Will switching from Canon to Nikon as a way to improve image quality make my stock images saleable?

Samyang 14mm or Rokinon 8mm fisheye? Which is better for landscapes?

Canon EF-S 10-18 or Tokina 11-16/2.8. :D Sorry. Neither one of these is ideal on a crop body as a landscape lens. The fisheye has too much distortion and would require defishing if you ever wanted a ...

Is there any point in ultra-high ISO for DSLR [not film]?

For some sort of photography high ISO is very important. At some point the picture quality does not matter as much as having at least taken a photo, even if it is very noisy. News journalists or ...

Why does Sony say that a 35mm lens is "35mm equivalent when used with an APS-C camera?"

The confusion here comes in entirely because "35mm" is the common name for the 135 film format, also known as "full frame" — and it happens to be the focal length of the lens you are looking at. The ...

Where does the price premium of full-frame come from?

The cost of manufacturing the larger chips is not simply the difference in the surface area of the two sensor sizes. This is the case due to the rejection rates of each for the same number of defects ...

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

I'm sure you've heard the old saying, "The best camera is the one you have with you." Some of my favorite photos are shots I've taken with my three-year-old Samsung Galaxy Note 4, a phone with a ...

Why are large zoom ratio constant apertures lenses not generally available?

It is more about ratios than addition/subtraction. 70-200mm is less than 3x from the shortest to longest focal length. That makes it possible to place all of the moving elements that enable the lens ...

Will switching from Canon to Nikon as a way to improve image quality make my stock images saleable?

I doubt the sensor is holding you back (for the record, I shoot Nikon). Much more goes into good IQ than just the sensor: lenses, lighting, and technique are all huge factors in the equation, this is ...

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 ...

APS-C lenses on full frame Mirrorless bodies

Since the adapter moves the lenses further from the sensor, I’d imagine that the coverage of the lens would be larger, and that the adapter or body alters focus to compensate. Is this thinking correct?...

Using FF lens on APS-C changes lens aperture value?

Neither the focal length of the lens nor the aperture of the lens change if we change the size of the sensor. What does change is the angle of view and the depth of field, but not the exposure. (We ...

Buying a Nikon DSLR Camera body only, is a 35mm and 55-200mm lens enough for most cases?

35mm is not wide enough for many types of general photography. With any group shots, (especially indoors) or any large outdor landscape scenes, you will need something like 16mm to 18mm to get ...

Does say a 35mm on an APS-C camera have the same facial/other deformations as a 35mm?

Short answer no - it will be approximately equivalent to the 50mm lens on a full frame camera. What you are referring to are issues of perspective. The perspective is not a property of the lens but ...

How does the smaller mirror in APS-C cameras offer these advantages?

Just about any wide angle (WA) or ultra wide angle (UWA) lens used with an interchangeable lens camera will use a retrofocus design. That does mean larger, heavier, and more complex than a non-...

How is focal length facial distortion different on an APS-C sensor compared to a full frame?

The facial deformations you are worried about are due to perspective distortion. Perspective is determined by one thing and one thing only: subject distance. Here's an example of focal length ...

Why don't my calculations based on a crop factor of 1.5 work for the Nikon P1000?

It is simply that the P1000 does not offer an APS-C sensor - as its manual and marketing site state it has a 1/2.3" sensor, which offers a crop factor of ~5.5.

Why don't my calculations based on a crop factor of 1.5 work for the Nikon P1000?

The P1000 unfortunately isn't an APS-C, it's far smaller at 1/2.3-inch, which gives it a crop factor of 5.6. Compared to a 35mm sensor it is tiny. From ApoTelyt.com - Nikon P1000 Comparison Review ...

There are many f2.8 zooms for FF. Why are there so few f2/f1.8 zooms for APS-C?
