LOWA Z-8S GTX C

Product Information

I like these boots, and I think they’ve become my new favorite hunting boots. They’re comfortable and protect my feet well, and stitch quality is quite good. They required no break-in, provide adequate arch support, and fit well. Teleconverters (TCs) work reasonably well simply because they are not “fast aperture” diverging lenses: they are designed to work best with lenses no faster than f/2.8. I didn’t notice any meaningful handling issues with this lens, although if you have big fingers, they might rub against the wide barrel of the lens when you grip your camera. It’s probably not a huge cause for concern. Aside from that, the lens handles just as smoothly as a typical Nikon Z lens, and it will feel very familiar if you’re used to the Z system. The Lowa Z-8S are very comfortable. The bottoms of these boots are soft and absorb a lot of impact, which is very important in a combat boot. Wearing something on your feet for up to 24 hours a day during those long military exercises or deployments, it’s a big deal when your footwear is comfortable.

Here are extreme worst-case examples had by exposing for the dark underside of a palm tree and putting the full disc of the sun in the corner. Ignore the rainbow effects around the sun at smaller apertures, these are sensor artifacts and not caused by this lens. S: Subliminally suggests sexual satisfaction. The "S" designation has no other purpose than subliminal seduction; Nikon and electronics and automobile and every kind of marketer have been using letters like "S" and "X" in model numbers since the 1940s for this same reason. Nikon called their first 1946 rangefinder lens mount the "S" mount, then went whole-hog to the "F" SLR mount in 1959, used "S" again when they updated their AI lenses to AI-"S" in 1983, created AF-"S" SWM lenses in 1998 and here it is again.In their teaser video and press release, Nikon placed a lot of emphasis on the bokeh of the 135mm f/1.8 S Plena – in a way not seen since at least the 58mm f/0.95 Noct, and perhaps since the Nikon 58mm f/1.4G. Given that, I was very interested in the sample images that accompanied the lens’s announcement. The Nikon Z 20mm f/1.8 S definitely shows quite a bit of vignetting, especially at large apertures. Take a look at the below chart: Nano Crystal Coat (N): Magic anti-reflection coating that has a variable index of refraction that's far more effective against ghosts and internal reflections than traditional multicoating. Filters last a lifetime, so you may as well get the best. The Hoya HD3 stays cleaner than the others since it repels oil and dirt. I can’t see any of the rubber sole being worn to any serious degree. They’ve been through a lot of rough terrain, hot weather, and winter climates and they still look and function great. Keep in mind, traction on ice isn’t the best.

These each have superb optics. I find the 24-70/4 zoom more useful, while this 50/1.8 is over two stops faster for use in low light. Finally you might also consider the Nikon Z 14-30mm f4.0 S as an alternative. It has the benefit of a 2.1x zoom range covering a wide range of very useful focal lengths starting at an ultra-wide 14mm offering an immersive 114 degrees viewing angle albeit at a meagre f4.0 focal ratio. It is shorter (at least in its collapsed state) and a bit lighter than the Z 20mm f1.8 S, it is so far the only 14mm full-frame lens which can use standard filters, and it offers very good optical performance which got it a Highly Recommended in my Nikon Z 14-30mm f2.8 S review. At 1150 EUR / 1300 USD it is similarly priced as the Nikon Z 20mm f1.8 S. So the choice is: flexibility in focal length or 2.3 EV more light gathering power. I know people who have gotten the GTX Z-8S, and in warmer climates they noted how they wished they went with the non-GTX ones. So be sure to know what you’ll be using them for mostly. There will always be a trade off between having a boot that can withstand deeper water and a boot that is breathable. How does this compare to the vignetting performance of the Nikon 20mm f/1.8G? The difference is actually quite drastic. The Nikon 20mm f/1.8G shows over 2 stops of vignetting at close focus, and over 3 stops when focused at infinity. So the Z-mount version is significantly better in comparison.

LOWA Z8S C Military Boots - Coyote Op

My first impressions of the Nikkor Z 50mm f/1.8 S were very good and closer examination of the images hasn’t changed my mind. It’s clear that it’s capable of capturing plenty of detail, which makes it a good match for the 45.7Mp Z7. Beyond its hunter role, the Z-8 is also outfitted for SAR duty by way of hoist-and-basket, FLIR (Forward-Looking InfraRed), and powerful searchlight in the "Z-8S" variant. This allows the helicopter to operate over-water and reclaim downed pilots or seaman as needed. Stability by way of a steady hand at the controls and an effective autopilot system aid in these types of actions. This version appeared in late-2004 and remains in active service with the PLAN. The "Z-8K" and "Z-8KA' designations represent modernized SAR forms. The "Z-8JH" is a specialized MEDEVAC variant.

This is the very worst I could get. This is the direct disc of the sun shining into the lens while exposing for the dark underside of a palm tree. You'll never see this unless you go way out of your way as I did here deliberately to do this. Focus accuracy and repeatability is critical to consistently produce sharp shots especially with large aperture lenses. Repeatability (the accuracy of focus on the same subject after repeated focus-acquisition) of this lens is very good (measured 98.2% in Reikan FoCal) with no outliers over a series of 40 shots. There is no focus variation whether the lens focuses from a closer distance or from infinity. Like I stated earlier, these boots have kept my feet dry and warm in cold / wet climates. There aren’t any drain holds on the side so water can’t get in that way. The materials are such that water literally slides down the side of the boot. They don’t absorb water easily at all. Comes with a soft pouch and the lens hood is included, reversible for transport. That’s similar to the F Nikkor but the new pouches for the Z lenses are disappointing: the material is flimsy and the pouch has no strings to pull it close. So if you put the lens in your bag it might easily slip out of its pouch and bang around unprotected. The Sigma has a nice well-padded case.[0] As we have seen so far from every Z-mount prime lens, Nikon has done an incredible job making each lens perform at the highest levels of sharpness and contrast, with very little sample variation. The Nikon Z 20mm f/1.8 S follows the same pattern, with superb overall performance. Take a look at the below Imatest MTF sharpness measurements:MELVILLE, NY (September 27, 2023) Today Nikon Inc. announced the release of the NIKKOR Z 135mm f/1.8 S Plena, an impressively unique lens for Nikon Z series mirrorless cameras. This new mid-telephoto prime lens bestows astonishingly high resolution, edge-to-edge brightness, incredible sharpness and spectacularly dramatic bokeh, all while elevating the threshold of what’s possible with optical technology.

Scrutinising images at 100% on a computer screen, reveals a slight fall in sharpness when the aperture is closed down from f/8 to f/11. There’s another very slight drop in sharpness at f/16, the smallest aperture. But it’s only really by comparison that you’ll spot this, the results are very good indeed. Chromatic Aberration, Distortion, Vignetting and Flare The good news here is that the Nikon Z 50mm f/1.8 S keeps chromatic aberration, distortion and flare under very tight control and while there is some vignetting, it’s not bad. I spent time hunting around high raw files with high contrast edges and only found the merest suggestion of chromatic aberration and nothing that would show up at normal viewing sizes. If this 1,200×900 pixel crop is about 6" (15cm) wide on your screen, the complete image would print at a huge 27½×41¼″ (70 × 105 cm) at this same high magnification. Even at the widest aperture, the Nikon Z 50mm f/1.8 S is sharp and there’s on slight fall-off towards the corners. Stopping down to f/2.0 brings out a little more detail. The optical path is based on 12 elements in 10 groups, and includes four aspherical elements and an ED (Extra-low Dispersion) element. The overall aim is to maximize sharpness and contrast while keeping distortions and chromatic aberrations to a minimum. Nano Crystal Coat is also applied to minimize ghosting and flare, and to help retain good contrast even when shooting into the light.The versatile 82mm filter attachment size enables the use of various lens filters designed to satisfy users’ creative intent. The Nikon Z 50mm f/1.8 S is bigger, heaver and more expensive than any Nikon 50mm f/1.8 lens ever, but that's because it's also the most complex and highest-performance 50mm lens ever from Nikon. The Lowa Z-8S weight just over 3 pounds for the pair. When I went from walking in my standard issue combat boot to the Lowa Z8S, it was like walking on a cloud. Now, there are definitely lighter combat boots out there, and if you’re not going to be wearing a boot through rugged conditions, then you may be okay going with a lighter boot, but for such a tough and durable boot like the Lowa Z-8S, I was surprised at how light they were. The last handling feature I’ll mention is stabilization. Even though image stabilization isn’t as useful for close-up and macro photography, I’m glad that the Z MC 105mm f/2.8 has vibration reduction built-in. At minimum, the view through the viewfinder is surprisingly nice and stable when vibration reduction is turned on. And if you have a Nikon Z camera without IBIS, it makes this lens all the more viable.
