Camera Lenses
Introduction
This Sigma 100-400mm gives an excellent compromise between finances 70-300mm lenses and whopping top notch-telephoto zooms.It’s nicely-constructed, handles properly and boasts a few useful up-marketplace capabilities.
In the long run, it’s a hard desire among this and Tamron's 100-400mm, however there’s no denying that the Sigma combines true overall performance and advanced capabilities at a bargain rate.
FOR
- Small and light for a ‘fantastic-tele’ zoom
- Excellent dealing with and overall performance
- Moderately priced
TOWARDS
- Handiest the mounting ring is weather-sealed
- Fairly slender f/5-6.3 aperture rating
- No tripod mount ring to be had
Sigma markets a hundred and fifty-600mm notable-telephoto zooms in its global imaginative and prescient line-up.
The ‘sport’ lens is going for all-out performance, even as the ‘cutting-edge’ edition aims to lessen the scale and weight, with minimum effect on image excellent.
Having said that, they’re each massive, heavy lenses that weigh in at nearly 3kg and 2kg respectively. As such, they’re heavy to carry around and experience even heavier whilst you get into prolonged periods of hand held capturing.by using stark contrast, Sigma’s more recent one hundred-400mm modern-day zoom is barely more than a kilo gram, and literally takes a load off.
Features
Capabilities 4 SLD (unique Low Dispersion) factors
Ring-type ultrasonic auto focus gadget
New-era optical stabilizer
As an immediate competitor to Tamron’s recently released one hundred-400mm lens, the Sigma is very comparable in size, weight and aperture score.
however, regardless of being simplest marginally heavier, the Sigma has a more complicated optical direction, based totally on 21 rather than 17 factors. of those, 4 are SLD (special Low Dispersion) elements, aiming to maximize contrast and sharpness at the same time as minimizing color fringing.
High-overall performance features include a ring-kind ultrasonic auto focus gadget with remodeled algorithms to growth operational pace.
Three switchable attention modes consist of manual focusing and each car-priority and manual-priority auto focus modes.within the latter, you can manually override auto focus without having to watch for it to fasten onto a topic, in addition to the use of guide override in non-stop or ‘AI Servo’ auto focus mode.
A 3-position auto focus variety limiter transfer allows you to fasten the variety either aspect of six meters.
Build nice and handling
Strong and sturdy creation
There’s no tripod mount collar available
Managing is assured with a smooth-action
Build quality feels appropriate at some point of, with a stable and robust production.
A climate-seal is suited to the mounting plate but there aren't any different climate-seals inside the lens. It’s just like the Sigma a hundred and fifty-600mm|C lens on this recognize.
There’s no tripod mount collar to be had for the lens, while Tamron sells one as an albeit luxurious elective greater.
Sigma’s stance is understandable, because the lens is marketed on its suitability for hand held taking pictures. then again, stability is bad whilst the use of a tripod or mono pod, particularly in portrait orientation capturing, so it might be great to have the selection of an non-compulsory ring.
Overall performance
Optical stabilization is really worth about four f/stops
Lens aperture is electromagnetically managed
Photograph nice is excellent at the entire
The auto focus machine is very rapid consistently accurate.
The guide-precedence override option works specifically well, as does the same M/A alternative in some Nikon lenses.
Optical stabilization is really worth about 4 f/stops in static mode and a touch less in panning mode.
Like many new Sigma and Tamron lenses, the diaphragm for controlling the lens aperture is electromagnetically controlled.
This has usually been the case for Canon EF like minded lenses, however Nikon has traditionally used a mechanical lever for altering the electromagnetic.
Conclusion
when a possible size and weight are greater crucial than outright telephoto reach, the Sigma 100-400mm offers an amazing compromise among price range 70-300mm lenses and whopping exceptional-telephoto zooms.It’s well-built, handles well and boasts some useful up-market capabilities, like twin-mode automobile-priority and manual-priority auto focus modes, along with two customization setups that are effortlessly available from a activate the lens barrel.
but, you’ll need to buy Sigma’s optional USB Dock to initially installation the ‘custom’ modes.
The Sigma is less highly-priced to shop for than the competing Tamron lens and plays each bit as properly in most respects, with a better degree of customization.
but, the Tamron steals a lead for sharpness within the valuable vicinity of the body, and has a greater complete set of climate-seals. ultimately, it’s a hard desire between the two lenses however there’s no denying that the Sigma combines desirable overall performance and advanced capabilities at a good deal fee.
