Cream of the crop: Sigma 50-100mm F1.8 real-world samples

10 Mar

The Sigma 50-100mm F1.8 is a bit of a rarity. It’s a fast telezoom designed specifically for Canon, Nikon and Sigma APS-C bodies, providing 75-150mm equivalent range (80-160mm on Canon bodies). Canon and Sigma mount versions should also work on Sony E-mount cameras with Sigma’s new MC-11 adapter. With Sigma’s ‘Art’ designation, it’s built to the company’s highest standards and includes a redesigned Hyper Sonic Motor and nine rounded aperture blades. We were lucky enough to get our hands on a pre-production model while we were in Japan for CP+ 2016, and didn’t waste any time putting it to work.

Due to our limited time with the lens, samples aren’t as varied as we’d have liked, but we’ll be adding more to this gallery once we get one back in. For now, enjoy a number of aperture progressions at various focal lengths to get an idea of edge-to-edge sharpness, chromatic aberration, and vignetting performance. Our preliminary thoughts are that sharpness and contrast are impressive for a F1.8 zoom, with center sharpness nearing its peak by F2.8, and extreme edge sharpness maximal by F5.6.

Sigma 30mm F1.4 DC DN Contemporary real-world sample gallery

09 Mar

Among all its releases at CP+ 2016, Sigma’s 30mm F1.4 DC DN Contemporary lens is the smallest in size, but its wide aperture should help it pack an image quality punch. Designed for Micro Four Thirds cameras and Sony E-Mount, the Sigma 30mm F1.4 uses a stepping motor for quiet autofocus, weighs in at a feathery 265g (9.3oz), and will retail for $ 339 when it’s released later this month.

During a visit to the Sigma factory in Aizu, Japan, we had a chance to test it out in a snowy winter wonderland. The lens is a pre-production sample, and the images were shot on a Sony a7R II in crop mode. We’ve included JPEGs processed from Raw using Adobe Camera Raw (some with and without manual distortion correction), and original Raw files as well, for your viewing pleasure. Check them out and see how the lens stacks up.

Panasonic Lumix DMC-ZS60 / TZ80 real-world samples and studio comparison

04 Mar

Panasonic’s ZS60 puts a lot of enticing features in a very small package. It’s an iteration on a tried-and-true travel zoom formula that combines a 24-720mm equivalent zoom, 18MP sensor, 3″ touchscreen and a built-in electronic viewfinder. The ZS60 also offers 4K/UHD video at 30p as well as Wi-Fi. We spent some time outside with the ZS60, even managing to catch a few breaks in the late winter clouds, and have a real-world sample gallery to show for it. Take a look at how it fares out and about and in the studio.

Sand and sun: Sony a6300 real-world samples

02 Mar

The Sony a6300 has some sizable shoes to step into. With a 24MP CMOS APS-C sensor, 8 fps continuous shooting with live view, 425-point on-sensor phase detect AF system and 4K video capture it looks like a solid update to the a6000, at least on paper. Eager to get our hands on a fully functional model, we joined Sony in Miami for some shooting opportunities. From bright white beaches to the intense action of a parkour gym (that’s a real thing), we’ve just started putting the a6300 to the test. Check out some preliminary samples.

Panasonic Lumix DMC-ZS100 / TZ100 real-world sample gallery

01 Mar

The Panasonic Lumix ZS100 made its debut in early January, offering a sizable 25-250mm equivalent zoom range to complement its 1″-type sensor. With a built-in viewfinder it certainly looks to be travel-ready, so we’ve taken it across land and sea to gather some initial sample images. While Adobe Camera Raw support isn’t available yet, we’ve made a few in-camera Raw conversions and will update this gallery when support arrives.

Pocketable APS-C: Fujifilm X70 real-world samples

09 Feb

Fujifilm’s new X70 compact camera puts the 16MP APS-C sensor from the X100T into a much smaller body, omitting an EVF but adding a 28mm equiv. F2.8 lens and articulating touch-sensitive screen. The X70 is certainly one of the nicest compact cameras to look at, and its specifications are pretty impressive, but what kind of images can it produce? We spent the weekend shooting with a production-quality camera.

Sigma 20mm F1.4 ‘Art’ lens real-world sample gallery

29 Jan

The Sigma 20mm F1.4 DG HSM | A is the newest member of Sigma’s family of ‘Art’ lenses. It’s also the widest member of the Art lens family, and with a maximum aperture of F1.4 Sigma claims that it’s the fastest 20mm lens in the world. We shot this lens on both 5DS R and 7D Mark II bodies, and since we had an EOS mount smart adaptor we even tried it on the Sony A7R II as well.

From what we’ve seen so far, this lens carries on the Art lineup’s tradition of stunning performance for the price, although this lens does have some characteristics that might not be ideal for all. For instance, it shows quite a bit of field curvature towards the brighter apertures when focused at nearer distances, and our rooftop shots show this particular copy performs better on the left side than the right side. As soon as an F-mount version of the Sigma is available, we plan on doing a shootout between this and the Nikon 20mm F1.8. In the meantime, enjoy a collection of images from the world’s widest F1.4 lens.

Still GReat: Ricoh GR II studio scene and real-world samples

22 Jan
The Ricoh GR II and a predecessor from the days of film – the Ricoh GR1

The Ricoh GR II is a modest update to the well-regarded Ricoh GR, as well an evolution of a beloved film camera, the Ricoh GR1. In this version, the high-quality formula remains: an 18.3mm (28mm equiv.) F2.8 lens in a compact body with a 16MP CMOS APS-C sensor inside. While the update doesn’t bring any image quality changes, it does offer a chance to run the new camera through our studio test scene, as it will be an obvious competitor to the Fujifilm X70 when it arrives. Take a look at how it holds up against other 16MP compacts, and see how the street-friendly camera performs out-and-about.

Nikon 24-70mm F2.8 ED VR real-world sample gallery

14 Jan

Winter can be a stark wonderland in the Pacific Northwest, especially east of the Cascade mountain range. Editor Barney Britton spent some time with the new Nikon 24-70 F2.8 ED VR lens amongst the snow-covered rolling hills, waterfalls, forests, and even sunny beaches our beautiful state provides. VR brings a level of hand hold-ability to a popular range of focal lengths that should make it easier to make sharp images with the 36MP Nikon D810.

Before you follow the link below to see how the lens performed in the set of real-world samples we provide here, it’s worth keeping some things in mind. A high-resolution camera demands critical focus: even the slightest misfocus will be easily visible, and small focus errors aren’t uncommon when using DSLRs in the field. Furthermore, on full-frame, even an aperture of F8 has limited depth-of-field, so infinity-focused shots may show a slight decrease in sharpness for objects closer in the foreground. With these caveats in mind, we still found the sharpness of the lens to be somewhat lacking relative to our high hopes.

We’ve only tested one copy of this lens, and it’s always hard to determine if the sample we received is truly a representative sample. We’ll be requesting a second copy to verify that our sample isn’t an outlier, but based upon findings from both DxOMark and Roger Cicala over at LensRentals, the less-than-stellar sharpness results aren’t too surprising. 

While sharpness is generally good, particularly across the field, absolute sharpness in the center doesn’t appear to be better, or even as good as, the original non-VR 24-70mm F2.8 Nikkor. Roger’s results, as well as DxO’s findings, confirm somewhat decreased central sharpness but increased consistency across the frame. Roger suggests this may in part be due to a prioritization of minimal field curvature and astigmatism with absolute sharpness perhaps being the cost. Our samples do appear to confirm a relatively flat field of focus – which will be useful for many applications. Close-up sharpness sometimes suffers, as does sharpness at the long end, while chromatic aberration continues to be an issue much like the original.

That said, overall build appears to be – at least subjectively – improved, and Nikon’s Vibration Reduction (VR) promises to be a boon for photojournalists. Paired with the D810, our experience and preliminary testing indicates VR to be incredibly effective, and we expect it’ll prove indispensable at times, while overall raising the convenience factor of the body and lens combo. For some, this may even make up for the less-than-ideal sharpness which, by the way, we only call out because of the high bar set by recent primes and venerable zooms like the Canon 24-70 F2.8 II (which lacks VR, mind you). In isolation, this new lens is plenty sharp. 

But without further ado, have a look at the sample gallery yourself, and let us know what you think in the comments!

246 Shades of Grey: Leica M Monochrom Typ 246 real-world and studio samples

11 Jan

The sensor in the Leica M Monochrom (Typ 246) is an interesting one. Without a color filter array, the 24MP CMOS sensor doesn’t lose sharpness through interpolation, much like a first-generation Foveon sensor or Pentax’s pixel shift mode found in the K-3 II. The catch is, of course, no color. However, it also means the sensor is more… well… sensitive at base ISO, making this ones’ base ISO 320 instead of 200 like its Bayer counterparts.

There is another issue, however. Even without a mirror flipping out of the way in this rangefinder, the shutter causes blur at speeds near 1/125sec when using the 90mm F2 Summicron. To see the true sharpness of the camera at base ISO, we recommend switching over to low-light mode where the shutter’s effect isn’t present.

You’ll notice that the M Monochrom is marked as non-standard. Keeping true to its rangefinder roots, it can only change shutter speed in half-stop increments, whereas our standardized Raw exposures are based off of third-stop increments. However, the M does do exposure compensation in third-stops, even though it will only report half-stops. Therefore we shot the M in aperture priority and bracketed +-1 stop EV. We then, since it didn’t report accurate shutter speeds in its metadata, chose the Raw exposure that was closest to Lab 50 without adjustments. JPEG images still follow our normal procedure.
