I'm not sure if you are asking about the micro four thirds standard or the 4:3 aspect ratio, so I'll answer both: Why do mirrorless cameras use micro four thirds? They don't, only Panasonic and Olympus build micro four thirds cameras, there are a lot of other companies making mirrorless cameras (for example: Sony, Fujifilm, Samsung, etc.) that have other ...

No.* The micro four thirds to four thirds adaptor is basically a tube which mounts the four thirds lens further from the sensor. In order to do the reverse you would have to mount the micro four thirds lens closer to the sensor, which is not possible as there is stuff in the way! *at least whilst preserving the ability to focus at moderate distances.

Can't say I've been doing what I would call serious landscape shooting with it, but I did take it as a second body while on a landscape trip. I was using it mostly while walking because I didn't want to take the DSLR out of the bag until I had reached my destination. So, I was using it handheld and without any filter. That said, the results were pretty good. ...

Your fears are completely unfounded. Landscape photography is one of the least demanding types of photography. Specifically: You can go as wide on full-frame as almost any format. Either get the Panasonic 7-14mm F/4 or the Olympus 7-14mm F/4 with the 4/3 to m4/3 adapter (this one lens is super-sharp). Most landscape shots are done with small apertures to ...

The Four Thirds standard for digital SLRs was designed by Olympus and Kodak to be the first system specifically made for digital, with high standards for telecentric lenses and other design choices for a modern era, rather than adapting a film lens mount. At the time, full-frame sensors were really out of reach in terms of cost, and the smaller sensor ...

Rather than calculating the crop factor from the diagonal regardless of format, this chart is based on the largest-possible cropped print from the respective sensor. For example, for 3:2 aspect ratio (as in 4×6 prints), the Four Thirds image is cropped along the long edges, while for 4:3 aspect ratio, Four Thirds is uncropped but APS-C or "full-frame" 35mm ...

You can use a Micro Four-Thirds lens on a Micro Four-Thirds camera and they are compatible between manufacturers, so Zuiko, Olympus, Panasonic, Leica, Sigma and Samyang lens are all compatible with cameras from Olympus and Panasonic as long as the mounts are Micro Four-Thirds. You can use a Four-Thirds lens on a Micro Four-Thirds camera with an adapter ...

This is my go-to resource http://www.four-thirds.org/en/microft/. At this site, you can find up-to-date news about the Micro Four Thirds industry (new cameras, technology breakthroughs, etc). They also lists the different cameras available in the Four Thirds and Micro Four Thirds formats. They appear to be sponsored by Olympus, but give seemingly unbiased ...

Don't forget about the range of lenses available to you. This site will show you all the brands involved with mFT. Also, just a side note about fitting FT lenses onto mFT bodies, the auto-focus isn't as efficient (as FT on FT). This is because FT uses Phase Detection while mFT uses Contrast Detection. There appears to be news floating around that Olympus ...

The image quality of a 4/3 and Micro Four-Thirds camera is exactly the same since the sensors are the same size. Therefore you can expect better image quality from newer 3/4 or Micro 4/3 cameras due to technological improvements. It is normal that there will be differences when changing models and even though what you are getting will be some kind of ...

4/3 rumors (http://www.43rumors.com/), while mainly about rumors for new products, also has a good bit of discussion about available lenses and ways to use these cameras.

It appears that the C mount had a flange focal distance of a little over 17mm, while the 4/3s system is a little over 38mm (this is due to the mirror). It's not actually possible without changing the lens or body construction and can't be done with a simple adapter. However, m4/3 is a little over 19mm. You may get a black border (due the the circle ...

The reason is historical. Before Micro Four-Thirds, there was Four-Thirds which defined a 4:3 aspect-ratio sensor. The reason is simply that Olympus research concluded that 4:3 aspect-ratio was most pleasing. They even had 4:3 half-frame (2X crop) film cameras. When Olympus and Panasonic decided to go mirrrorless, it was advantageous to bootstrap the system ...

As I understand you have a lens with manual diaphragm ring. Your camera will be able to adjust it only if you close it to maximum. In other words, if you want your camera to be able to change aperture, you need to fully close the aperture manually.

If my underwater macros with the PEN2 are anything to go by, I would think that the PEN3 is as good or better for macro - with the kit lens. The picture I linked is of a 1cm large pygmy sea horse, and it is cropped. The resolution is amazing and I am sure you can easily fit two of them into the picture with a 3D lens without loosing sharpness or too much ...

Thom Hogan of http://www.bythom.com fame is also writing at http://www.sansmirror.com/. I find that he has some good reviews and some good insight as to what 4/3rds is currently good at and where it needs to improve.

I think it is similar as with electronic extension tubes for example. Why such simple thing made from anodized aluminum tube is relatively cheap and almost the same tube with a few electronic is more then 5 times more expensive? For example, some time ago I was looking for Canon Eos (do not have any Canon camera now) extension tubes, there were some for ...
