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 ...

Confused about T-stop number. Does it account for crop factor?

Crop factor has nothing to do with T-stop. T-stop is strictly about light transmission which affects exposure. If a lens could be 100% transmissive the T-stop and f-number of the lens would be the ...

Why automatic mode is worse than manual?

It's not so much that manual is better, but that manual is more controlled. Shooting all the time on full manual will teach you what to do & what not to do. It will take longer & you will ...

Are micro four thirds lenses fully interchangeable between brands?

You can mix & match lenses from different manufacturers, with just a few caveats. Autofocus will work for all MFT lenses on all MFT bodies (that I am aware of). Image stabilization: Olympus does ...

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 ...

Backyard wildlife zoom question factoring distance

Given the ratio of the Canon APS-C crop factor (1.6) to the MFT (2.0) sensors, the equivalent of a 300mm on your camera is 300*1.6/2=240mm so a bit longer than your intended lens (200mm). The zoom ...

Backyard wildlife zoom question factoring distance

Assuming all other things are equal: Your Canon 80D has a crop factor of 1.6. This means that your 300mm lens has an effective focal length of 300mm × 1.6 = 480mm. A micro-4/3s camera has a crop ...

No. Micro Four Thirds is not an open standard. The specification is available to member companies, which are listed here. It's not a tiny list, but it's not large, either. Your best bet is found on ...

Confused about T-stop number. Does it account for crop factor?

The f-stop is a simple ratio. It is the focal length divided by the working diameter. We use this value to compare the image brightness of one lens vs. another. The f-stop is often in error because it ...

Can I adapt an E-mount rectilinear lens on a micro four thirds body?

I would suggest looking into a shift or tilt-shift adapter, to mount say a wide-angle Canon EF or Nikon AF-S lens. This way, you have a much wider selection of regular lenses to choose from than just ...

Can I use a 35mm film lenses on Micro 4/3 at the same focal length?

The focal length stays at 50mm, but the field of view will be that which you would get from a 100mm lens on 35mm film. Depth of field characteristics at a given aperture will be that of a 50mm lens. ...

Does a Ring-Ultrasonic EF-S lens require power to manually focus? (using with adapter)

You can manually focus most, but not all, Canon USM lenses without any power supplied from the camera. In fact, you can manually focus them when they're not even attached to a camera. The EF-S 17-...

Ultrawide Micro Four Thirds lens: is it better to use a wide full frame lens with a Speed Booster or a native lens?

It's better to get the native lens. Because you will never find a low-cost 15-30mm equivalent rectilinear lens for MFT in full-frame glass. You do get, that even with a speedbooster at x0.71, that ...

You speak of two different factors. The 2x crop factor equivalence of 4/3 sensors is based on the sensor size. The 4/3 camera sensor has a crop factor of 2, meaning it has a diagonal 1/2 the ...
