Going beyond this snapshot of effect features and characteristics, what are the differences between the Panasonic Lumix DMC-GM1 and the Panasonic Lumix DMC-GX850 ? Which one should you buy ? Read on to find out how these two cameras compare with deference to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by adept reviewers .

Body comparison

The side-by-side display below illustrates the physical size and system of weights of the Panasonic GM1 and the Panasonic GX850. The two cameras are presented according to their relative size. Three straight views from the front, the lead, and the back side are shown. All width, acme and depth measures are rounded to the nearest millimeter.

Both cameras are available in three different colors ( black, flatware, bolshevik ). Size Panasonic GM1 vs Panasonic GX850
Compare GM1 versus GX850 top
Comparison GM1 or GX850 rear
If the front watch area ( width x altitude ) of the television camera is taken as an aggregate measure of their size, the Panasonic GX850 is notably larger (28 percent) than the Panasonic GM1. furthermore, the GX850 is markedly heavier (32 percent) than the GM1. In this context, it is worth noting that neither the GM1 nor the GX850 are weather-sealed. The above size and slant comparisons are to some extent incomplete since they do not consider the interchangeable lenses
that both of these cameras require
. In this finical case, both cameras feature the lapp lens backing, so that they can use the same lenses. You can compare the optics available in the Micro Four Thirds Lens Catalog. Mirrorless cameras, such as the two under consideration, have the extra advantage of having a short flange to focal plane distance, which makes it potential to mount many lenses from early systems onto the camera via adapters .

The adjacent table lists the principal physical characteristics of the two cameras alongside a wide set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your choice from a broad list of cameras there .
Any camera decision will naturally be influenced heavily by the price. The manufacturer ’ mho suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The GX850 was launched at a markedly lower price ( by 27 percentage ) than the GM1, which puts it into a different market segment. normally, retail prices stay at beginning close to the plunge price, but after respective months, discounts become available. Later in the merchandise cycle and, in particular, when the substitution model is about to appear, farther dismiss and stock headroom sales frequently push the television camera monetary value well gloomy .

Sensor comparison

The size of the imaging detector is a all-important determinant of image quality. A large detector will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a detector of the same technical generation. Further, a large detector television camera will give the photographer extra creative options when using shallow depth-of-field to isolate a subject from its backdrop. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses .
Both cameras under consideration feature a Four Thirds sensor and have a format gene ( sometimes besides referred to as “ crop gene ” ) of 2.0. Within the spectrum of television camera sensors, this places the review camera among the medium-sized detector cameras that aim to strike a balance between persona quality and portability. Both television camera have a native aspect proportion ( detector width to sensor height ) of 4:3. Panasonic GM1 and Panasonic GX850 sensor measures
The two cameras under review do not alone share the like detector size, but besides offer an identical resolution of 15.8 megapixels. This similarity in detector spectacles implies that both the GM1 and the GX850 have the same pixel concentration, american samoa well as the same pixel size. It should, however, be noted that the GX850 is much more holocene ( by 3 years and 2 months ) than the GM1, and its detector will have benefitted from technical advances during this time. Coming back to sensor resolution, it should be mentioned that the GX850 has no anti-alias filter installed, so that it can capture all the contingent its detector resolves. The Panasonic Lumix DMC-GM1 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 125-25600. The equate ISO settings for the Panasonic Lumix DMC-GX850 are ISO 200 to ISO 25600, with the possibility to increase the ISO stove to 100-25600. Technology-wise, both cameras are equipped with CMOS ( Complementary Metal–Oxide–Semiconductor ) sensors. Both cameras use a Bayer filter for capturing RGB colors on a squarely grid of photosensors. This placement is found in most digital cameras. GM1 versus GX850 MP
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This avail is based on lab examination and assigns an overall score to each camera detector, ampere well as ratings for moral force range ( “ DXO Landscape ” ), color depth ( “ DXO Portrait ” ), and low-light sensitivity ( “ DXO Sports ” ). Of the two cameras under consideration, the GX850 has a markedly higher DXO score than the GM1 ( overall grade 7 points higher ), which will translate into better image choice. The advantage is based on 0.9 bits higher discolor depth, 1.6 EV in extra dynamic range, and 0.2 stops of boil down low abstemious sensitivity. The stick to table provides an overview of the physical detector characteristics, angstrom well as the detector quality measurements for a excerpt of comparators .

many modern cameras are not merely able of taking distillery images, but besides of capturing video footage. Both cameras under retainer are equipped with sensors that have a sufficiently high readout amphetamine for moving images, but the GX850 provides a better television resolving power than the GM1. It can shoot movie footage at 4K/30p, while the GM1 is limited to 1080/60i .

Feature comparison

apart from body and detector, cameras can and do differ across a stove of features. The GM1 and the GX850 are alike in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD.

articulated screen that can be turned to be front-facing. This characteristic will be appreciated by
vloggers and photographers who are interested in taking selfies. In contrast, the GM1 does not have a selfie-screen. The reported shutter travel rapidly information refers to the habit of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, both cameras under consideration feature an electronic shutter, which makes completely silent shooting possible. however, this mode is less desirable for photographing moving objects ( risk of rolling shutter ) or shooting under artificial light up sources ( risk of flickering ). The Panasonic GM1 and the Panasonic GX850 both have an intervalometer built-in. This enables the photographer to capture time relapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera gun trigger and relate software. Concerning the repositing of imaging data, both the GM1 and the GX850 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s .

Connectivity comparison

For some imagination applications, the extent to which a television camera can communicate with its environment can be an important aspect in the camera decision summons.

The GX850 is a recent model that features in the current merchandise line-up of Panasonic. In contrast, the GM1 has been discontinued ( but can be found pre-owned on ebay ). As a replacement in the same trace of cameras, the GM1 was succeeded by the Panasonic GM5. Further information on the two cameras ( e.g. exploiter guides, manuals ), deoxyadenosine monophosphate well as associate accessories, can be found on the official Panasonic web site .

Review summary

so what conclusions can be drawn ? Is the Panasonic GM1 better than the Panasonic GX850 or frailty versa ? Below is a compendious of the relative strengths of each of the two contestants .

Arguments in favor of the Panasonic Lumix DMC-GM1:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More compact: Is smaller (99x55mm vs 107x65mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 65g or 24 percent) and hence easier to carry around.
  • More heavily discounted: Has been available for much longer (launched in October 2013).

Advantages of the Panasonic Lumix DMC-GX850:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor’s full resolution potential.
  • Better image quality: Scores markedly higher (7 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (1.6 EV of extra DR).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60i).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (10 vs 5 flaps/sec) to capture the decisive moment.
  • More affordable: Was introduced into a lower priced category (27 percent cheaper at launch).
  • More modern: Reflects 3 years and 2 months of technical progress since the GM1 launch.

If the count of individual advantages ( bullet train points above ) is taken as a guidebook, the GX850 is the clear winner of the contest ( 9 : 4 points ). however, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decisiveness on a new camera. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person matter to in family portraits has discrete needs from a landscape shooter. Hence, the decision which television camera is best and worth buy is often a very personal one .

How about early alternatives ? Do the specifications of the Panasonic GM1 and the Panasonic GX850 seat the camera among the top in their class ? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the craw. In any lawsuit, while the comparison of technical specifications can provide a utilitarian overview of the capabilities of different cameras, it says little about, for example, the shooting know and imaging performance of the GM1 and the GX850 in practical situations. User reviews that are available, for example, at amazon can sometimes shed unaccented on these issues, but such feedback is all besides often partial, inconsistent, and inaccurate .

Expert reviews

This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites ( amateurphotographer [ AP ], cameralabs [ CL ], digitalcameraworld [ DCW ], dpreview [ DPR ], ephotozine [ EPZ ], photographyblog [ PB ] ). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier luff that a television camera decisiveness is often a very personal choice .
The review scores listed above should be treated with care, though. The assessments were made in relation to alike cameras of the lapp technical generation. frankincense, a sexual conquest needs to be put into the context of the launch date and the launch price of the television camera, and rating-comparisons among cameras that span long meter periods or concern very differently equipped models make small sense. It should besides be noted that some of the follow-up sites have over clock altered the way they render their verdicts .
