Distortion is clearly being helped along by the camera body, something that results in amazingly low figures. There is -0.03% barrel distortion at 70mm and -0.01% at 105mm. At 135mm, this lens achieves the remarkable result of 0.00% distortion and this means literally none, not even to as many decimal points as we could wish. The lens at this point is perfectly rectilinear. At 180mm, a tiny bit of pincushion distortion can be measured at +0.02%.

Give it a try now with a similar division by 2. What is the Quotient and Remainder of 180 Divided by 2? Here we provide you with the result of the division with remainder, also known as Euclidean division, including the terms in a nutshell:You can adapt to an oven if it averages just a handful of degrees away from the correct temperature, by turning it up or down a little. But if it's a larger gap – or the temperature fluctuates a lot during cooking – you could be in for some disappointing results. How oven temperature affects cooking and baking The greatest magnification may well be at the widest setting, but the price we pay is a huge amount of field curvature, so if the centre is sharp the edges might not be and if the edges are sharp the centre may be out of focus. Stopping down helps, and to be fair, the effect can be used in a creative way. The amount by which the least accurate ovens we've tested exceed the set temperature Oven thermometers Provincial Key Laboratory of Preventive Medicine, School of Public Health, Nanchang University, Nanchang, China The trinity of lenses is now complete – the Nikkor Z 17-28mm, 28-75mm and now 70-180mm – all with an f/2.8 maximum aperture and matching 67mm filter threads. We have already seen this of course, as the Tamron set of the same specification lenses has been around for a while. However, the design and fine tuning of the Nikkor Z versions may be similar but not necessarily identical. The differences may well be interesting, but the main focus here is that we have a new, interesting choice within the repertoire of Nikkor Z full frame optics. Why 70-180mm, and why not 70-200mm? That is just one of the questions to seek an answer to as we delve deep and see how the new lens performs in the studio and on location, using the 45.7MP Nikon Z9 full frame camera body.
System connection G1½ male (boiler), G1 female (heating circuit). Suitable for pumps DN 25 with G1½ x 180 mm. More importantly, the subinhibitory concentration of SYG-180-2-2 (4 μg/ml) is not only non-toxic to human cells but can also inhibit the formation of biofilm. We concluded that SYG-180-2-2 had the potential to become a new type of antimicrobial drug used in clinical practice. Data Availability Statement If we want the f/2.8 aperture and can happily sacrifice 20mm at the telephoto end of the lens, the new lens looks to be an extremely sound VFM choice. Flare control is extremely impressive and it is difficult to induce any sign of artefacts. In the most challenging situations there may be some minor signs of flare, but nothing unduly significant. The lens is very easy to get along with and the loss of 20mm focal length at the longest end is not really felt. What is felt is the reduction of weight and bulk whilst at the same time enjoying the fast, bright f/2.8 aperture. In terms of handling, a lovely lens indeed, so now let's see if the performance matches the high standard that the Nikon Z9 camera will demand.Apochromatic lenses have special lens elements (aspheric, extra-low dispersion etc) to minimize the problem, hence they usually cost more. Ovens often have all sorts of hi-tech features including steam cooking and self-cleaning, and some can even be controlled remotely by an app on your phone. But, unfortunately, this doesn't mean they get the basics right. We sometimes come across ovens that soar to 220°C when set at 180°C. The thin focusing ring has just enough resistance to avoid accidental operation, but perhaps slightly more would be advantageous. It is however a minor point. Focusing is an area where clearly the lens has been redesigned for the Nikkor Z system, as the closest focus is the same in both AF and MF. The closest focus point varies with focal length and the maximum magnification of 0.48x is at the 70mm setting. This is almost half life size. Greater magnifications can be obtained by using the Nikkor Z teleconverters, the 2x converter resulting in an almost life size magnification of 0.96x. Both Z TCs are compatible, with Z TC-1.4x giving a focal length range of 98-252mm and the Z TC-2.0x giving 140-360mm.
