The Sony FE 90mm f2.Eight Macro G OSS was the primary macro lens for E-mount corrected for full-frame mirrorless cameras, upon which it’ll ship as much as 1:1 / 1x magnification from a distance of 28cm. It was introduced in 2015 and adopted by the Sony FE 50mm f2.Eight Macro in 2016. Macro lenses with focal size round 100mm are standard for macro pictures and general-purpose use as they provide extra working distance than shorter focal lengths. This makes it simpler to mild your topic and fewer probably for small critters to draw back. Sony added optical SteadyShot (OSS) picture stabilization to the lens, a spotlight limiter, an AF-lock button, and a twin MF mechanism: Whenever you depart the focus-ring within the entrance place the lens has the same old focus-by-wire performance with variable gearing for very exact focusing. However while you full the main focus ring again it switches to linear gearing which permits for sooner focus motion.
The Sony FE 90mm f2.Eight Macro G OSS is listed at 960 EUR / 1100 USD / 850 GBP.
Details from the catalog
Let’s evaluate the Sony FE 90mm f2.Eight Macro G OSS (“Sony” for brief) to the Sigma 105mm f2.Eight DG DN Macro Artwork (“Sigma Artwork”). As typical I’ve rated the options with a [+] (or [++]), when it’s higher than common and even state-of-the-art, a  if it’s customary or simply common, and [-] if there’s an obstacle.
Measurement (diameter x size): At 79 x 131mm (3.1 x 5.2in.) plus 51mm for the lens hood (94mm diameter) the Sony is of comparable dimension because the Sigma Artwork at 75 x 136mm + 57mm lens hood. Each are usually not small lenses. 
Weight: 602g (21 oz.) plus 43g for the lens hood. The Sigma is 708g + 47g lens hood. [+]
Optics: The Sony is a fairly advanced design with 15 components in 11 teams together with one aspherical and two particular dispersion components. That is just like the Sigma Artwork (17 components in 12 teams) ). The Sigma Artwork has fluorine-coating on the entrance factor to repel water, mud, and filth and make cleansing simpler – which the Sony appear to overlook. [+]
Closest focus distance is 0.28m (0.92ft.) with a magnification of 1:1 which is what you come to count on from a macro lens. This leads to a working distance of solely 0.13m (0.4ft.). The Sigma Artwork achieves the identical magnification at a barely bigger working distances. Each lenses don’t prolong whereas focusing and the Sony achieves a magnification of 1:10 at a distance of 1.07m (3.5ft.), the Sigma Artwork at 1.24m [+]
Use with teleconverters: No. The Sigma Artwork most likely might be used with Sony’s teleconverters (attempt before you purchase). 
Filter-thread: 62mm, identical to the Sigma Artwork. [+]
Picture stabilization: The Sony has optical stabilization not like the Sigma Artwork which depends solely on the built-in sensor-shift stabilization Sony A7 / A9 / A1 digital camera our bodies present. [+]
Auto focus: Constructed-in AF drive-by-wire. Handbook-focus override is by merely turning the devoted focus ring if the main focus ring is within the ahead place (marked “AF”). The main target ring has a variable gearing on this place which permits for very exact guide focus when turned slowly and is a boon when taking pictures macro images. Pull the main focus ring in the direction of the digital camera (marked “MF”, see above) the main focus motion switches to linear gearing (overlaying the entire focus vary in 140 levels) which makes easy focus pulling for videographers straightforward and is far sooner. On this mode the Sony exhibits focus distance plus magnification. Each the Sony and the Sigma Artwork even have an additional button on the lens which could be assigned many alternative capabilities (e.g. AF-lock) plus a spotlight limiter change providing three place as you may see beneath. [+]
Aperture: The Sony has no aperture ring not like the Sigma Artwork which has a de-clickable ring with 1/Three cease clicks. Focusing doesn’t change the aperture-value of the lens, so even at a magnification of 1:1 the lens nonetheless exhibits f2.Eight though it clearly darkens by 2 EV. That signifies that the efficient aperture of the lens is f2.8-f22 at infinity and f5.6-f44 at minimal object distance. The Sigma Artwork is identical on this respect. 
Lens profile: The lens comes with a lens profile for vignette-, CA- and distortion-compensation which could be managed from the digital camera. That’s the identical as with the Sigma Artwork. [+]
Covers full body/FX or smaller. Similar with the Sigma. [+]
Value: 960 EUR (incl. 19% VAT)/ 1100 USD / 850 GBP. The Sigma Artwork prices 749 EUR / 799 USD / 699 GBP. 
The lens comes with a tender pouch. The plastic lens hood is included and is reversible for transport. [+]
Sealing: sure, a rubber grommet on the lens-mount plus additional particular weather-sealing all through the development, identical to the Sigma Artwork. [+]
The rating within the “features-department” is 0[-]/4/10[+]. The Sony FE 90mm f2.Eight Macro G OSS presents a pleasant characteristic set. Noteworthy are the optical picture stabilization and the twin focus motion.
There are lot of macro lenses for Sony cameras. However if you need autofocus and a light-weight telephoto attain there are actually solely three native mirrorless designs for E-mount:
- Sigma has the 105mm f2.Eight DG DN Macro Artwork from 2020. The lens is equally sized however about 100g heavier than the Sony. And at 749 EUR / 799 USD / 699 GBP about 20-25% cheaper. The lens has a de-clickable aperture ring however no optical picture stabilization.
- Sigma additionally has the 70mm f2.Eight DG Macro Artwork from 2018. The lens has a slimmer construct and is a bit lighter than the Sony and at 500 EUR / 570 USD / 450 GBP additionally less expensive. Nevertheless it extends when focusing shut and has a 22% shorter attain which most likely additionally interprets in shorter working distances at comparable magnifications. And it doesn’t supply optical picture stabilization or an AF-lock button.
- From Tokina there’s the FiRIN 100mm 2.Eight FE Macro, an unique mirrorless design from 2019. It prices 540 EUR / 600 USD / 580 GBP. It’s a bit lighter and shorter than the Sony however extends when focusing. And it doesn’t supply optical picture stabilization or an AF-lock button.
Right here is the angle of view that the Sony FE 90mm f2.Eight Macro G OSS produces in comparison with the Sigma 105mm f2.Eight DG DN Macro Artwork:
Focus accuracy and repeatability is essential to constantly produce sharp pictures. Repeatability (the accuracy of concentrate on the identical topic after repeated focus-acquisition) of the Sony FE 90mm f2.Eight Macro G OSS is fairly good (measured 98.7% in Reikan FoCal) with no outliers over a sequence of 40 pictures. There’s nearly no focus variation whether or not the lens focuses from a better distance or from infinity and I detected little or no looking. The lens focuses in round 0.6 sec from infinity to 1.07m (1:10 magnification), which is just a bit sooner than the Sigma 105mm f2.Eight DG DN Macro Artwork at 0.7 sec.
The main target ring is 30mm broad. Its steel floor is structured for higher grip and could be operated with one finger. Whenever you change the focus-ring from AF to MF focus distance is straight away set to the final place in MF. That is perhaps disturbing at occasions. However I feel for macro work you’d use the MF place to shortly get the lens to focus after which change to the AF place to manually fine-tune focus in your topic. AF-operation of the lens in photo-mode can’t be heard from the skin and if you happen to file video with the built-in microphone AF can also be silent.
As you pull focus, you’ll discover fairly some focus respiratory: the picture turned 9% much less magnified after I adjusted focus from infinity to 1.07m. That is seen and might be distracting when taking pictures movies.
To check the effectiveness of the picture stabilization with the Sony FE 90mm f2.Eight Macro G OSS on a Sony A7R II digital camera physique, I did a sequence of 120 test-shots hand-held with shutter speeds from 1/100 of a second all the way down to 1/6 sec at 4.5m distance. I used the pictures at 1/100 sec with SteadyShot=off as reference of how good my hand-holding was on the time of the check and Reikan FoCal did the chore of evaluating the sharpness of all pictures.
Right here’s the outcomes: With SteadyShot switched on the combo produced outcomes all the way down to 1/25 sec (2 stops) with a clearly larger fee of sharp pictures than at 1/100 sec with SteadyShot=off. At 1/12 sec (Three stops) common high quality turned comparable. However at 1/6 sec (Four stops) outcomes turned very erratic with solely a 3rd of the pictures usable. This is a bonus from the picture stabilization of three stops.
I can not decide how efficient Sony’s OSS is at nearer distances nevertheless it is perhaps higher than picture stabilization based mostly purely on sensor shift. As you get nearer to your topic the impact of shake is multiplied by the magnification and it is best to adapt shutter pace accordingly even with OSS – or use a tripod.
Subsequent take a look at my high quality outcomes!
