When it comes to choosing a Sony TV, there are typically two main options that consumers face – the Sony 400 and the Sony 600. Both models offer great features and benefits, but which one is right for you? In this blog post, we’ll take a closer look at the key differences between the Sony 400 and 600 models to help you make a more informed decision.

Above: …while taking a closer look at the subject shows the lens is capable of capturing very crisp details. These are all mostly static subjects though, so let’s see how well the lens auto-focuses. The diameter of the Bokeh balls in the center is determined by the entrance pupil of the lens which is 71mm at 400mm focal length – the same as for the Nikon Z 70-200mm VR S at 200mm. Compression of the circle towards the corners is relatively strong wide open. The circle of confusion in the center stays round even down to f11. The inside of the Bokeh balls is only lightly textured but there is some outlining – albeit without coloration from loCA. This reads in steps of 5mm from 100~200mm, steps of 10mm from 200~360mm and steps of 20mm from 360~400mm.

Canon RF 100-400mm F5.6-8 IS USM Build and Handling

Fastest in their class. Referring to Sony’s 35mm full-frame E-mount cameras, a9 at 20fps, a7R III at 42.4MP at 10fps. According to Sony tests. The lens has a rounded nine-bladed aperture that produces circular bokeh at the center of the frame. Moving outwards towards the edges, the bokeh balls turn more into slanted cat-eye shapes. There’s a slight rim to the bokeh balls but overall it looks excellent. Out-of-focus areas are able to cleanly melt away and do not contain busy harsh edges. Above: Zooming-into the middle of the image once again shows very fine details with no evidence of any undesirable artefacts and again no benefit to closing the aperture any further.

The Sony FE 100-400mm f/4.5-5.6 GM OSS has similar size, tripod collar, macro ratio, weight and price, and is also Made in Japan. For less money, the the B+W multicoated 010 MRC is an excellent filter, as is the 77mm Nikon Clear (NC - UV) and the basic multicoated Hoya filters, but the Hoya HD3 is the toughest and the best. All-in-all the new Nikon Z 100-400mm f4.5-5.6 VR S zoom lens is sharper than it’s predecessor and also the better alternative to using the Z 70-200mm f2.8 VR S with TC-2.0x. Evidence to its superior performance are the results on a TC-1.4x which are only a tad softer although the teleconverter magnifies any fault of the lens attached to it by 1.4x.

If this 1,200×900 pixel crop is about 3" (7.5cm) wide on your screen, the complete image would print at a large 14×21″ (35×55 cm) at this same high magnification. The Z 100-400mm VR S is the first super-telephoto lens in Nikon’s Z-mount line-up. Naturally, if you shoot with a DSLR or have an FTZ/FTZ II mount adapter for your Z-series camera, you’re spoilt for choice when it comes to super-tele prime and zoom lenses. The Sigma 150-600mm f/5-6.3 DG OS HSM | C is a high performance telephoto zoom lens for Canon EF mount cameras, engineered for full frame image sensors. It has a contemporary design and advanced optical construction including three FLD glass elements and four SLD glass elements to minimize chromatic aberration and produce sharp images throughout the zoom range. There are a few key things to consider when deciding whether a 400mm or 600mm lens is right for you. The first is the size of your sensor – if you have a full frame camera, then the 600mm lens will give you a much wider field of view than the 400mm lens. If you have a cropped sensor camera, then the 400mm lens will give you a similar field of view to the 600mm lens on a full frame camera. About the same size and weight as Nikon’s fully pro-grade Z 70-200mm f/2.8 VR S‘trinity’ zoom, the 100-400mm naturally delivers twice the maximum focal length, but with a narrowing of aperture rating, which varies from f/4.5 to f/5.6 as you extend through the zoom range.

People worry waaaaay too much about lens sharpness. It's not 1968 anymore when lenses often weren't that sharp and there could be significant differences among them; ever since about 2010 all new lenses are all pretty much equally fantastic. This lens also features an integrated tripod collar, water and oil repellant coating on the front element, and a durable magnesium alloy casing. Sony 400Mm F2 8 Wildlife Built to do full justice to Sony’s prestigious Alpha A7 and A9 series full-frame mirrorless cameras, this lens also works a treat with APS-C format E-mount bodies, where it gives an effective zoom range of 150-600mm. Build quality is fabulous, with a really solid yet refined feel to the construction and a more comprehensive set of weather-seals than is fitted to Sony’s 70-100mm G-line lens for it’s A-mount cameras.Just grab the electronic focus ring at any time for instant manual-focus override anytime the camera is awake. There’s also no focus limiter, which could be useful if you’re trying to stop the lens going through its entire range of focus distances in, say, low light or when you’re shooting through a busy foreground. As it is, the RF 100-400 will focus from infinity down to as close as 88cm / 2.89 feet. How close it can focus actually breathes a bit as the lens zooms in and out – at 100mm it focuses as close as 120cm / 3.94 feet; at 400mm it focuses as close as 105cm / 3.44 feet.

Above: Next here’s the view at 200mm, where the maximum aperture has dimmed by two thirds of a stop to f7.1. We’re used to seeing robust kit from Pentax with impressive build quality, and this lens is no exception. It feels particularly solid and has a durable, weather-sealed construction. The flipside is that it’s physically larger and noticeably heavier than competing lenses, weighing in at 2kg. That’s nearly twice the weight of the Sigma and Tamron 100-400mm lenses, although they’re only available in Canon and Nikon mount options. Nikon’s original AF 80-400mm was the company’s first lens to feature VR (Vibration Reduction). That’s been updated in the new AF-S version, but it’s still only worth about 3-stops and is less effective than in the cheaper Tamron 100-400mm. It does have a switchable dual-mode autofocus system, enabling you to give priority to autofocus or manual override. This itself isn't a problem; what matters is that outside air is constantly pumped past your sensor, along with whatever dirt comes with it. lenses are ideal for capturing images with incredible detail and clarity. They’re often used by bird photographers, as they allow you to fill the frame with your subject.Weighing in at 1,435g (with tripod collar attached), the Z 100-400mm VR S certainly feels a purposeful lens, although it’s a little lighter than its 80-400mm F-mount counterpart. It’s only marginally bigger and heavier than the Z 70-200mm, but feels undeniably big and chunky on a Z 6 or Z 7 type body. Build quality is excellent, with comprehensive weather-seals and a fluorine coating on the front element, befitting a lens that is often favored for all-weather action, sports and wildlife photography.
