Sum-up
The Sony FE 100-400mm f4.5-5.6 G Master is a telephotograph zoom for its e-climb up mirrorless cameras, and chastised for use on full-frame bodies. Announced alongside the professional Alpha A9 body, information technology delivers the longest reach of Sony's pure e-mount lenses to date. Information technology's besides the fourth lens to link up the high-terminate G Original series and like the others aims to deliver both high resolution across the whole zoom, focusing and aperture ranges, as well as attractive bokeh.

The Sony FE 100-400mm f4.5-5.6 G Master is a telephoto zoom for its e-climb down mirrorless cameras, and corrected for use on full-frame bodies. Announced alongside the professional Alpha A9 body in Apr 2017, it delivers the longest reach of Sony's native e-mount lenses to date; it's also the fourth lens to join the high-end G Master series.
Like the other G Overlord lenses, the FE 100-400mm f4.5-5.6 GM aims for both adenoidal resolving power across the stallion zoom, focusing and aperture ranges, as substantially equally attractive out-of-focus rendering, or bokeh. It measures 94x205mm, weighs 1395g, has a 77mm filter thread and a 98cm closest focusing distance. The 22 factor / 16 group optical design includes one Super ED and two Erectile dysfunction glass elements to derogate chromatic aberration whole maximizing resolution. Meanwhile, Nano Arkansas coating minimizes flare out and ghosting.
The FE 100-400mm f4.5-5.6 GM features optical image stabilisation, a stiffness adjustment for the zoom ring, a dust and spatter-proof barrel, a removable tripod foot, customizable focus-hold buttons, and is matched with the SEL14TC and SEL20TC tele-converters. Interim the nearest focus distance of 0.98m allows you to attain a maximum overstatement of 0.12 to 0.35x, while the dual focusing groups see to it asperity is maintained at close rove. I've used the FE 100-400mm f4.5-5.6 at a variety of events connected both the Important A9 and A7r Mark II bodies and can share my experiences and a large selection of sample distribution images below.
Sony FE 100-400mm f4.5-5.6 G design
Measuring 94mm in diameter, 205mm in length and weighing 1395g (with tripod invertebrate foot removed), the FE 100-400mm is unsurprisingly one of the largest lenses in Sony's mirrorless catalog. IT's not unwieldy, only does feel best-balanced on larger bodies, in peculiar the Alpha A9 which was launched aboard IT. This is not a lens you'd want to use for long on the smaller bodies, so much as the new Mark I A7 operating theater A6000 series.
The physical body prize, like all G Master lenses, feels massive and confident in your hands with the zoom and manual focusing rings turning smoothly. A thin twistable ring allows you to correct the stiffness of the zoom ring, and while it doesn't go A far as to offer a complete lock, I constitute it did foreclose creep at any focal length when the lens was six-pointed straight prepared or weak. Federal Reserve note the samples I tested were new though, so these could loosen over time. In price of creep, the point of maximum 'slippage' is around 200mm, but with the genus Lens zoomed to 400mm, the cask seemed happy to stay in position still when the stiffness was at its loosest setting. As you zoom the lens to longer focal lengths, the barrel extends quite significantly atomic number 3 illustrated in the images below.
A removable tripod foot is supplied with the lens, along with a moldable bayonet strong-arme with a lockup button and small sliding window that allows you to adjust polarizing filters. Speaking of filters, the lens takes 77mm diameter accessories.
The barrel also features three focus-hold buttons which can be customized from the body to deliver a different function if preferred; line they all share the same function though. You can also pose the lens to focus with its full range or between 3m and eternity.
Sony FE 100-400mm f4.5-5.6 GM optical construction
The Sony Fe 100-400mm f4.5-5.6 employs 22 elements in 16 groups and includes one A-one ED and ii Male erecticle dysfunction lenses. The nine-blade iris system offers maximum and minimum apertures of f4.5 and f22 at 100mm or f5.6 and f40 at 400mm. I'll corroborate at which focal lengths the aperture reduces soon. The lens also features optic stabilization which operates in two axes; mountain it on a body with collective-in stabilisation and it'll work in conjunction with IT to deliver five-axis of rotation compensation.
The 4x physics range takes you from short to long-wooled telephotograph coverage and delivers the longest reach of whatsoever Of import mirrorless lens to date. If you'd like even tighter coverage, the lens is well-matched with the SEL14TC and SEL20TC tele-converters.
Mounted along an APS-C body like the A6500, the field-of-view is reduced to 150-600mm, which could be extended further to 1200mm equivalent with the optional 2x converter.
While organized for shot distant subjects, the FE 100-400mm f4.5-5.6 performs double-duty American Samoa a fairly presentable conclude-upward lens system. The minimum focusing outstrip of 0.98m may not sound particularly close-set, but with the lense zoomed to 400mm, you can achieve magnifications up to 0.35x. Major still, the couple focusing groups allow the lens to deliver equally crisp results at its closest focusing distance; here are whatever examples.
You can also course economic consumption it for portraits, although at longer focal lengths the subject will understandably be quite a distant and detached. That said, if you can co-ordinate them successfully, you can use the long focal length to effectively wipe out backgrounds even at f5.6. Here's some examples.
The two-dimensional-perspective at farsighted focal lengths butt as wel bring on well with landscapes, especially with series of rolling hills, surgery for merely picking-unfashionable distant detail. Like all long-dated lenses though, the greater the focal distance, the more in all probability you'll notice the soft effects of atmospheric disturbances. If the heat's rising, you'll inevitably suffer from belittled resolution.
Sony FE 100-400mm f4.5-5.6 GM focusing
The Sony Fe 100-400mm f4.5-5.6 Gram becomes the first Alpha mirrorless lens to offer dual focusing groups which work at the same time. This combination of a threefold linear centrifugal and Direct Ram SSM allow the lens to focus very swiftly, while also maintaining sharpness throughout the focal range and at all focusing distances.
I ill-used the electron lens on some the A7r Sucker II and A9 bodies to shoot a variety of action and came book binding very impressed. In particular when mounted on the A9 with its new AF scheme, there seemed little the combination struggled with. I shot track and field, cyclists, and horse-jumping, and returned with a very screaky polish off rate, even when shooting at the maximum frame rate of 20fps. While sports, fulfill and wildlife shooters will aspire to the compounding of this lens on the A9 body, I also enjoyed exploitation IT on the A7r Mark II; Here's a sequence I took with the lens on that consistency at its maximum frame rate of 5fps.
Whatever I guesswork, the lens snapped into focus quickly and without fuss. Whether shooting sports or wildlife, portraits with face and eye detection, or close-ups, the Atomic number 26 100-400mm felt very confident.
I'll conclude this review soon erstwhile I've completed some additional tests with the lens, only thus far I'm very affected. It feels very comfortable shooting a wide variety of subjects and so far has performed alright crossways the focal range and the least bit apertures and focusing distances. I look brash to spending more time with it. In the meantime, I hope you delight the following selection of try images!
