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 Micro Four Thirds lenses so expensive compared to Canon?

The basic answer is that Canon's 50mm f/1.8 is an exception even within Canon's lineup. It's an old, simple design with nothing fancy, and made to be mass-produced cheaply. Compare the Canon 85mm f/1....

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 ...

Why are Micro Four Thirds lenses so expensive compared to Canon?

Camera and lens designs are full of compromises and certain decisions have knock on effect throughout the system. Olympus decided on a particularly thick filter stack when specifying the micro four ...

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 ...

Is it a good idea to use adapted tele lenses with a micro four thirds camera for fast moving (nature/wildlife) photos?

As someone who occasionally indulges in bird photography, shoots micro four-thirds, and has adapted manual lenses to her Canon dSLRs, I'd say don't do it. The lens will be disproportionately big and ...

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 ...

Is it true that cameras with larger sensors are more likely to mis-focus under low light?

No, larger sensor cameras are not more likely to mis-focus - if you take the Canon 1DX (with a modern lens) for example, it's a full-frame camera that's about as far away from "likely to mis-focus" as ...

Light meter calculations on micro four thirds

No. As far as exposure value goes, an f-stop is an f-stop. It's only where depth of field is concerned (and noise calculations derived from "total light captured", if you're the type who has to go ...

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 think the key thing for here is that smaller sensors inherently have more depth of field at the same aperture number and framing. That means that with a larger sensor, focus is more critical. It's ...
