Lenses for Micro Four Thirds compared.

43rumors reader Dave sent me a huge file (download the PDF here) whcih collects all the MTF charts from MFT lenses (Some of the MTF charts are from DxO and ePhotozine). Dave writes:

The object of the exercise is to present the bulk of the Olympus, Panasonic and third party lenses for the Micro Four Thirds (mFT/m43) compact system camera mount in one place, grouping lenses that might be the subject of some comparison prior to purchasing. (You can cut and paste rows if  necessary.) Only lenses native to the m43 system and the prior Four Thirds (FT) mount – which can be used with an official system adapter – are shown. Bear in mind that FT lenses from third parties are usually re-purposed full frame and APS-C sized lenses and as such are often significantly larger and heavier than even their native Four Thirds counterparts, let alone their m43 descendants. The point of considering older FT and compatible lenses really comes down to two features: the fact that some older lenses can be had quite cheap and that lenses designed for a larger format utilise just part of the image circle. This second aspect means that those lenses that typically score poorly when paired with a larger sensor can actually be quite good on the smaller FT sensor *, as the corners and edges are cropped away.
Equally, some of the more modern native mount lenses with large, fast apertures (for example the Voigtlander Hyperprimes) are big and heavy by m43 standards. Other specialist lenses, such as those for cine and special effects are not shown, as I think people wanting those will not really want or need to compare them with standard lenses, nor may sharpness be the starting point for a comparison.

* Note that the FT and mFT sensors are exactly the same size – it is just the flange distance that differs. You can use an older four thirds lens on the newer micro four thirds bodies with an adapter, but not the other way around. However, focussing performance is generally significantly poorer for the older lenses.

Panasonic Lumix TZ100 review by CameraLabs


The new Panasonic TZ100 is not a MFT camera but one of the best fixed lens compacts on marked. CameraLabs posted their TZ100 review and writes

There are 1in class cameras with pocket bodies and brighter lenses, but their zoom range is much shorter, typically 4x or less – for example the Canon G7X, Canon G9X and Sony RX100 IV. There are 1in class cameras with longer zooms, but their bodies are much larger too – for example the Canon G3X or Sony RX10 II. But right now there’s nothing out there which couples a 1in sensor with a 10x zoom in a pocketable body, and impressively also gives you a built-in viewfinder and 4k video.
As of early 2016, there’s nothing to match it if you desire the quality of a 1in sensor with a longish zoom that will fit in your pocket.

Panasonic GX8 review at Dpreview:


Dpreview posted the full Panasonic GX8 review and writes:

The Panasonic Lumix DMC-GX8 is a impressive mirrorless camera that ticks most of the boxes that many enthusiasts are seeking. Its new 20MP sensor is impressive, Depth from Defocus AF system top-notch, and Dual IS system innovative. The camera’s touchscreen and Wi-Fi features are both well-implemented, and its weather-sealed body is solid.
Still shooters will need to decide whether having to use the electronic shutter to avoid blur is worth its potential trade-offs, while videographers who want to hook up an external mic or HDMI cable may not enjoy losing the flexibility of the camera’s rotating rear screen. It’s for these reasons – especially shutter shock – that we are unable to give the GX8 our highest award.

The new Panasonic Leica 100-400mm lens will finally start to ship next week on March 15 according to BHphoto.

Daniel Cox just returned from Japan where he met with the Panasonic Lumix team and spent ten days photographing Japan’s Winter Wildlife. Most of the work was with the Lumix GX8 and the new Leica 100-400mm zoom. You can see the image gallery here http://archive.naturalexposures.com/proofing/C00003nDou.nKOU0/G0000gFSGHEV7FMk
He also produced a short video on shooting the GX8 in some very wintery conditions:
