Review: Lumix GM1
I loved the GX7 released by Lumix last year, and recently I got a closer look at the teeny little brother GM1. It's so small it's crazy, but in a good way.

The Photography Blog

The smallest of the Micro Four Thirds (MFT) systems so far, the GM1 is smaller than many compact cameras yet still retains the ability to swap lenses across the entire range from Lumix and Olympus. In order to keep the form factor smaller than a regular MFT they even developed a new 12-32mm lens that fits snug with the GM1.

The new lens is almost inseparable once matched to the GM1, because when you put a regular MFT lens onto the body it looks rather silly. We tested the GM1 with a prime 25mm f/1.4 and found it performed every bit as good as the bigger GX7. The autofocus operation was characteristically impressive of the Micro Four Thirds line, with the advantage of a rear touch screen to employ the "tap and shoot" mode if the shutter button seems too old fashioned for you.

To make the GM1 as tiny as possible some of the more common place features for a mirrorless camera are absent. Gone is an articulated rear screen, the electronic viewfinder and even a flash sync. The battery is scaled down to a 680mAh version as part of the space saving process. Panasonic have retained a very basic flash unit latched down with a minuscule release switch, which cranes itself into position and looks as delicate as a butterfly.

You wont need a flash very often though, with the same excellent ISO performance inside the GM1 that we saw in the GX7 released in 2013. In dull lighting the camera produces good images that hit above it's size.

Because the GM1 uses contrast-detect the entire sensor is effectively your autofocus grid. Face recognition and subject tracking modes work well, or you can set a specific point on the screen and adjust the size of that point. Anything goes and pretty much everything works.

Unlike some of the other Lumix models this one skips on the NFC, so connecting to your smartphone is not quite as smooth as other models from Lumix. Once you're connected everything works nicely, and the standard Lumix Link app does a good job of driving the camera. There are better smartphone-to-camera apps on the market to be sure, but the Lumix version is not the worst either.

Connectivity is a major selling point for the GM1, because it's small enough to have with you all the time and convenient enough to want to upload the pics to social media.

A key ingredient to making the GM1 useful at this size is an effective user interface, and the GM1 takes full advantage of the touch screen to make adjusting shoot settings simple and fast. You don't have to be an expert to drive it, there are sufficient on screen prompts to get most jobs done. Additionally you can customise a wide range of the buttons according to what tasks you tend to employ the most.

Sending images to your phone over Wi-Fi Direct, for example, can be accessed quickly while reviewing, with the ability to select a bunch of images and upload scaled down versions to your phone. The Lumix Link app must be running before you begin the process, but after that it's painless and quick.

Making the Micro Four Thirds this small did require some re-eingeering of the shutter, and the new design is lighter and more compact than anything else wearing the Lumix label. Extending the performance is an electronic shutter which allows the GM1 to shoot faster speeds and more rapid continuous frames under specific circumstances.

Maxed out at 1/16,000th of a second and grabbing 10 frames per second the JPG files are limited only by the speed of your SD card. We put an Extreme Pro Sandisk 90mb/s card in the GM1 and held down the trigger until the card was full. There is also an option to shoot reduced resolution JPGs and grab 40fps. At the other end of the speed spectrum the GM1 has in-built support for time lapse shooting, making this a very compact and discrete platform for time lapse work.

Size does matter and it's possible the GM1 is just too small for many photographers. Put side by side with the GM1 the already modestly sized Lumix GX7 looks like a monster. The GM1 is so small that clipping on a regular Micro Four Thirds lens looks out of scale, and indeed defeats the purpose of such a compact design.

If you do intend to invest in good quality lenses then the bigger models such as a Lumix GX7 really does make more sense. Better battery life, the flexible rear display and a more tactile feel in the hand are just some of the rewards when buying bigger.

As a stepping stone to more advanced photography there is considerable appeal in the GM1 however. You can cut your teeth on manual modes, learn to appreciate the effects of aperture and ISO, and keep the door open to experimenting with how a different choice of lens will change your photography. Eventually you're likely to outgrow the GM1, but in the meantime you'll have something the size of a compact that shoots like an entry level DSLR.

Good things do come in small packages, so how small is right for you?

Kit Lens
Lumix 12-32mm ASPH f/3.5-5.6
Stepping motor technology has enabled a much smaller lens design compared to other Lumix lenses. Unique to the 12-32mm is a manual locking function that packs away the lens and minimises the extension. A lens cap is still manually clipped on the front. It means you have three steps to complete before taking a shot: power up the camera, extend the lens and remove the cap.

Fine Prime
Leica DG Summilux 25mm f/1.4 ASPH
If you like a fast prime lens then the 25mm f/1.4 will provide excellent results on any of the Micro Four Thirds camera bodies, including the GM1. Equivalent to a 50mm on a full frame DSLR, the prime is built for quality and matches the excellent autofocus abilities of the MFT systems. It's fast in low light, offers shallow depth of field and is great for both portraits or still life. Everybody needs a standard prime lens in their kit, and for owners of the Lumix G series or Olympus OMD range this one is hard to beat.

LUMIX S9 Review

Welcome to the LUMIX S9, the new full-frame mirrorless made by stuffing the inner workings of an S5II into a tiny little camera body. Panasonic didn’t skimp on features, and even added a few new ones. Let’s take a quick look at why the new LUMIX S9 is such a great addition to the L-mount collection, and why I think it’s a tonne of fun.

Sigma 14mm F1.4 Field Review

This is my new favourite lens for the Arctic. It’s not just for stars, and not just auroras. It’s also a creative lens choice when you want to do something a little bit different with landscape photography.

S-E100 F2.8 Macro for L-Mount

The S-E100 F2.8 Macro lens for L-Mount has just been released by LUMIX, and it’s very different to anything I’ve used on a mirrorless system before. It’s a super compact lens for super small subjects, but delivers super-sized performance and in particular the Autofocus is on a whole other level.

Micro Four Thirds meets Bokeh

What is the secret to getting maximum bokeh out of the Micro Four Thirds format? or any other MFT camera? Lets step deep into the beauty of bokeh and look at just how much of a full-frame look you can squeeze out of smaller sensors.

Leica Summicron-SL 50mm f/2 ASPH

Another great fast 50mm prime for the L-mount, this time with a seriously impressive build quality that we have come to expect from Leica.

Custom Settings for the LUMIX G9II

I've prepared an outline of my custom setup for the LUMIX G9II, plus a copy of my settings ready to download to your camera and customise for your own needs. A great way to get started and try some of the various features built into this amazing little MFT body.
