I know, for example, that my 85mm 1.8S is pretty sharp and has been reviewed favourably etc. and is nice and light. All that is far less important than the way it is able to let me look at images and portraits where I am getting consistently pleasing results. I have decided I like lenses which somehow manage to get out of the way and let me look at facial expressions, the smile, the eyes etc and concentrate on how the subject looks and how they respond to the results. 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. It did take me a while to realise that what I had bought was actually exactly what I had always wanted but didn’t expect to find in a studio lens. My thoughts of buying an updated 70-200 have become irrelevant. It is sharper and very impressive but I don’t actually need it. 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 lens manages to bring out the subtlest of details even in very dull ambient lighting, aided by Nikon’s in-camera Active D-Lighting.

The lens body features two lens Fn buttons, to which a wide variety of functions can be assigned. One is positioned on the top of the lens enabling smooth adjustment of settings even when shooting in vertical orientation. My biggest gripe is the length of this lens which had the benefit of being designed for a mirrorless system with a very short flange distance of only 16mm. Still it is as long as the older DSLR design (with adapter). Sony shows that you can built an optically very good 20mm f1.8 which is much more compact: Their mirrorless system with the Sony 20mm lens is 34mm shorter than the Nikon mirrorless combo. Have a look at the following comparison: The base Z-8 design incorporated three turboshaft engines for the power needed and these output 1,570 horsepower per unit, driving a six-bladed main rotor blade assembly and a five-bladed tail rotor assembly (facing portside). The fuselage is deep with the nose section covered over in framed windscreens. The radar unit protrudes forward through its blister assembly at the nose. The helicopter relies on a tricycle wheeled undercarriage that is retractable and the outboard sponsons operate as floats allowing the helicopter to land on water for water-rescues operations. The cabin includes side-by-side seating for the two pilots, room for a flight engineer, and enough space to seat passengers, support rescue equipment or patient litters. The hold can also double as a cargo area to which point the helicopter can serve in the at-sea replenishment role. Its versatility goes beyond this for the platform can also be pressed into service during humanitarian crisis' as well as in the fire-fighting role. As an aside – I personally hope that Nikon releases a line of pancake primes for the Z series, to take advantage of the lightweight cameras. For some genres of photography, f/1.8 lenses are overkill, even if they are high in quality. Why not make a very good f/2.8 or even f/4 version that weighs significantly less? Landscape and travel photographers would certainly find a lot of value in lenses like that, especially in combination with the excellent IBIS of the Z-series. NIKON Z 6 + NIKKOR Z 50mm f/1.8 S @ 50mm, ISO 100, 1/200, f/5.6 As usual I’ll have a look at the technical data of the new Nikon Z 20mm f1.8 S first. I’ve rated the features with a [+] (or [++]), when it’s better than average or even state of the art, a [0] if it’s standard or just average, and [-] if there’s a disadvantage. For this comparison I use the Nikon AF-S 20mm f1.8G (“F Nikkor” for short) and the Sigma 20mm f1.4 Art (“Sigma”). Please keep in mind that the Sigma has a 2/3 of a stop brighter focal ratio which influences size and weight of that lens.

They do all of this while keeping my feet dry and happy, and I believe the Z-8S GTX is the most-comfortable LOWA footwear I have ever worn. DisclosureVignetting can be a problem for more than just the obvious reason of darker corners. It also leads to bokeh-related issues, particularly a “cat’s eye” shape in out-of-focus corners of the image. Lens designers can minimize vignetting at wide apertures by giving the lens a larger image circle. (This often improves corner sharpness at wide apertures as well.) However, the tradeoff of a larger image circle is that the lens must be larger, and usually more expensive, than normal. And while Nikon has kept the Plena to a pretty reasonable 995 grams / 2.19 pounds, it’s still a big piece of glass.
