Enjoy high quality performance, low cost prints and ultimate convenience with the PIXMA G series of refillable ink tank printers. Sony have positioned the lens elements at the rear to avoid a top-heavy feel and improve balance. They have also designed it to be used for hand-held photography, with no need for a monopod. The revised 24.6MP Exmor RS CMOS sensor and Bionz XR processing engine are 8x more powerful than those in the Sony A9 II. They support real-time subject recognition for people, cats, dogs, birds, planes, cars, trains, and other objects with auto-focus/auto-exposure at 120fps, and can capture up to 192 frames in RAW (about 6GB of information) per second.

Focal ratio: All lenses in this comparison have a focal ratio which becomes smaller the further you zoom in. The Tamron 70-300 starts at f4.5 at 70mm focal length and reduces its focal ratio to f4.8 from 88mm, f5.0 from 116mm, f5.3 from 144mm, f5.6 from 175mm, f6.0 from 217mm, and f6.3 from 268mm onwards. The F-Nikkor 70-300 is a bit brighter (1/3 of a stop at the long end), same with the Z-Nikkor 100-400. [0] As a high-end L-lens, the 100-300 is of course weather-sealed to the same standard as previous Canon super-telephotos, including a rubber grommet at the mount. Note the white coating on the barrel is now more effective under hot conditions than the old 300’s coat. Consequently, in use it feels well matched even to a small body like the Sony A1 camera, as shown in the photos below, although fitting a vertical battery grip definitely helps with the overall balance.Let’s compare the new Tamron 70-300mm f4.5-6.3 Di III (“Tamron 70-300” for short) to theNikon Z 100-400mm f4.5-5.6 VR S (“Z-Nikkor 100-400”) and Nikon AF-P 70-300mm f4.5-5.6E ED VR (“F-Nikkor 70-300”) which was introduced in 2015 and still can be used via FTZ adapter on Nikon’s Z cameras. As usual 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. The lens is incredibly easy to use. Simply attach it to your camera body of choice and go have fun. As far as telephoto lenses go, it is straightforward. The Fujifilm 70-300mm lens has the added benefit of the focus limiting switch to achieve the swiftest autofocus, whether you are out in the wilderness or in the studio. I love the convenience of the aperture ring on the lens. The aperture can still be controlled on the camera body for anyone who doesn’t enjoy this feature. The zoom ring is effortless and allows for multiple perspectives to be achieved within seconds.
So here they are with their hoods attached, where you’ll see the working length has now become quite similar, indeed almost identical if you add the EF to EOS R adapter to the prime on the left to use it on a mirrorless body. An inch is the name of a unit of length in a number of different systems, including Imperial units, and United States customary units. There are 36 inches in a yard and 12 inches in a foot. The inch is usually the universal unit of measurement in the United States, and is widely used in the United Kingdom, and Canada, despite the introduction of metric to the latter two in the 1960s and 1970s, respectively. The inch is still commonly used informally, although somewhat less, in other Commonwealth nations such as Australia; an example being the long standing tradition of measuring the height of newborn children in inches rather than centimetres. The international inch is defined to be equal to 25.4 millimeters. Efficiency is also a key factor, especially when it comes to keeping a handle on heating bills, so look for energy-efficient models that save both energy and money; these are often aluminium, low-water-content radiators. Like most Tokina lenses of the era, the Tokina 300mm f/4 doesn’t handle flare particularly well. Overall contrast is reduced substantially when shooting against the sun. At times this defect can lend a dreamy quality to photographs. Chromatic AberrationWhere they are required to be cut this can be carried out using a fine tooth saw or hot wire cutter. No further storage requirements are needed as the product is unaffected by both UV light and water. Measuring 84mm in diameter and 187mm in length, the Tokina 300mm f/4 is a small lens. In comparison, the Nikon 300mm f/4D AF-S with its 90mm diameter and 222.5mm length is a lot bigger. It also weighs 300 grams more than the Tokina. The Canon EF 300mm f/4 L USM (The non-Image-Stabilized model from 1991 and the IS model from 1997) lenses from the 90’s compare favorably with the Tokina in weight, but their size is almost identical to that of the Nikon lens. The only 300mm f/4 full-frame lens that handily beats the Tokina in size is the relatively new Nikon 300mm f/4E PF ED VR lens whose usage of Phase Fresnel (PF) elements make it a tiny 147.5mm in length and just 755grams. Thanks to its small size and form factor, the Tokina balances effortlessly on even the smallest of DSLR’s which makes it a fantastic companion for long hikes. With their slender 300mm width, these radiators boast a notably narrow profile. Among them, you will find an array of options, ranging from extremely compact to impressively tall and substantial units. As a result, these versatile radiators have the capacity to effectively warm anything from small cloakrooms to much larger spaces. Sony says the lens produces bright images throughout the frame, with no darkening in the corners. It includes 2x XD linear motors for fast and precise autofocus and is balanced for comfortable handheld shooting with smooth panning. A number of controls allow for customizing its performance and a new button allows for instant APC-S cropping. The lens is compatible with Sony's 1.4x and 2.0x teleconverters, which turn it into a 420mm F4 and 600mm F6 lens, respectively.
A millimetre (American spelling: millimeter, symbol mm) is one thousandth of a metre, which is the International System of Units (SI) base unit of length. The millimetre is part of a metric system. A corresponding unit of area is the square millimetre and a corresponding unit of volume is the cubic millimetre. Build quality is excellent, something of a relief given the price-tag. The Sony FE 300mm F2.8 GM OSS has a sealed dust and moisture resistant design and a rubber ring around the lens mount, all of which makes it well-suited to life both indoors and out, although Sony do state that it it is not completely moisture and dust proof. Datasheet ǀ Declaration of Performance - DoP ǀ BBA Certificate ǀ Installation Guide ǀ Certificates ǀ Brochure ǀ SPEC Sheet The sensor contains 759 focus points that cover 96% of the sensor area. In addition to S, M, and L focus spots, Sony added XS and XL options so photographers can dial in the exact focus spot areas they prefer. The camera supports in-body, 5-axis optical image stabilization that covers 8 stops. Sony says this supports exposure values down to -5 at f/1.8.

Alongside the A9 III, Sony showed off a fresh piece of glass to its wide selection of lenses: the FE 300mm F2.8 G Master OSS prime lens. The lens joins Sony's top G Master sports and wild-life focused lenses, including the 400mm F2.8 GM OSS and the 600mm F4 GM OSS. It features a similar magnesium alloy build, is dust and moisture resistant, and includes fluorine protection on the front glass. It measures 10.4 by 4.8 inches (HW) and weighs 3.24 pounds. It's about half the weight of the larger 400mm lens. (Credit: Sony) The Sony FE 300mm F2.8 GM OSS lens has a metal lens mount. It has a drop-in filter holder at the rear which accepts 40.5mm filters. There is no front filter thread. As such, it not only becomes the mirrorless replacement for the EF 300mm f2.8L II from 2011, but also arguably an alternative to the EF 200-400mm f4, especially as the new lens will work with Canon’s existing RF teleconverters to extend its reach.Add the RF 1.4x TC and the 100-300 2.8 becomes a 140-420 f4.Add the RF 2x TC and it becomes a 200-600mm f5.6, which could be useful for more distant sports or even wildlife. Size (diameter x length): 77 x 150mm (3.0 x 5.9in.) plus 67mm for the lens hood. The F-Nikkor 70-300 is 81 x 146mm + 78mm lens hood. Add 30mm for the FTZ adapter to use it on a Nikon Z camera. The Z-Nikkor 100-400 is 98 x 222mm + 65mm lens hood. All three lenses in this comparison extend when zoomed to their longest focal length: The Tamron 70-300 extends to a maximum total length (incl. lens hood) of 277mm, the F-Nikkor 70-300 to 310mm (incl. FTZ adapter), the Z-Nikkor 100-400 to 336mm. [+]
We didn't experience very much "hunting" at all, either in good or bad light, with the lens accurately focusing virtually all of the time, and it's also a very quiet performer that makes it ideal for movie shooting. Aperture ring and other control elements: The focus ring on the Tamron 70-300 can be assigned in camera to operate the aperture, exposure compensation, or ISO sensitivity – or simply switched off. This is similar to the multi-function control ring on the Z-Nikkor 100-400 but there are no other control elements/buttons/switches. The F-Nikkor 70-300 has no aperture ring but sports two switches to control focus and VR mode. [+] Like other super-teles there’s a selection of switches, starting with Lens Function which you can use to pre-program a set distance like a goal or nesting branch.Comparing prices will also ensure companies can’t take advantage of you and give you a fair price. 4. Word of Mouth Next the RF 400 2.8 super-tele prime lens which can mount natively to the EOS R3, although I couldn’t fit the hood into the frame.
