Introduction

A few 12 months after the discharge of the Zeiss Otus 28mm 1.4 Distagon – to the shock of many – Zeiss launched this Zeiss Milvus 25mm 1.4 Distagon. Virtually as advanced optical design, virtually as large, virtually as heavy, however “solely” half the worth – making it the most costly lens of the Milvus lineup. What are you giving up when it comes to efficiency in comparison with the 28mm Otus? Let’s attempt to discover out on this overview.

Dealing with/Construct high quality

The Milvus lenses characteristic the identical casing design as the upper finish Otus lenses (and in addition the Batis and Touit lenses), however not everybody was pleased with the design decisions made by Zeiss right here, let me let you know why.

The lens includes a large rubberized focus ring. It rotates 172° from infinity to the minimal focus distance of 0.25 m. For me the resistance of the main focus ring is also a bit larger, however that could be a matter of private style to some extent.

I’m not an enormous fan of the rubber used for the main focus ring (and aperture ring of the ZF.2 model). It already doesn’t scent notably good and I’ve extreme doubts about its longevity. It additionally attracts all form of particles.

The casing appears to be fabricated from some form of steel and is a bit shiny and slippery. All of the markings are engraved and full of paint.

The lens ships with a bayonet sort lens hood however I purchased a used one which got here with out it. The lens definitely appears to be like nicer with the hood hooked up, but it surely makes the entire package deal even bulkier and more durable to hold round.

The lens additionally doesn’t characteristic a tripod foot, contemplating its weight I might have preferred one although.

The 82mm filter thread is unquestionably extra manageable than the Zeiss Otus 28mm 1.4‘s 95mm one, however it’s nonetheless greater than that of another 24mm 1.4 lens (Nikon AF-S 24mm 1.4G and Canon EF 24mm 1.4L II USM: 77mm, Sony FE 24mm 1.4 GM: 67mm).

This can be a overview of the EF model which might simply be tailored to E-mount and Z-mount cameras.

Vignetting

mild falloff

That is one other a type of instances, that clearly exhibits: an enormous lens doesn’t equal low vignetting figures. In actual fact these are the very best vignetting figures I’ve seen from a ~24mm 1.4 lens but. The Nikon AF-S 24mm 1.4G and the Sony FE 24mm 1.4 GM present about 2/3 of a cease much less vignetting on the most aperture as does the Zeiss 28mm 1.4 Otus. The Canon EF 24mm 1.4L USM II exhibits related however nonetheless barely decrease vignetting figures. 

It is strongly recommended to take a look at this text first to get an concept how this brightness graph works.

optical vignetting

Quick lenses normally present a noticeable quantity of optical vignetting. With out going an excessive amount of into technical particulars optical vignetting results in the truncation of sunshine circles in the direction of the borders of the body.
Within the heart of the body virtually each lens will render an ideal circle, however solely lenses with very low optical vignetting will maintain this form within the corners.
So within the following comparability we transfer from the middle (left) to the acute nook (proper) and see how the form of the sunshine circle modifications.

0.5 m focus distance

The quick 24mm 1.4 lenses I reviewed didn’t encounter extreme points on this class and that’s once more the case right here – all of them carry out related right here.

Nevertheless, one factor that caught me abruptly are the pronounced onion ring constructions. The Nikon AF-S 24mm 1.4G and the Canon EF 24mm 1.4L USM II are hardly higher, however the Zeiss 28mm 1.4 Otus featured aspherical components with method smoother surfaces and I might have anticipated the identical right here. Not the case.

Sharpness

MTF-Graphs

The MTF graphs promise a formidable efficiency at f/1.4 within the heart of the body and the internal midframe, within the outer midframe and the corners we do see a notable quantity of astigmatism although. Stopped all the way down to f/4.0 the astigmatism is considerably lowered.

It’s attention-grabbing to check these graphs to these for the Zeiss 28mm 1.4 Otus. Within the heart of the body this 25mm Milvus really exhibits a better efficiency at f/1.4, the Otus has a extra even and subsequently larger efficiency farther away from the middle although. Stopped all the way down to f/4.0 they appear related with the Otus exhibiting a bit larger decision within the outer midframe and the corners.

Sadly Zeiss doesn’t publish graphs exhibiting the efficiency at 20 occasions the focal size for the Milvus lenses, they solely do for the Oti.

Most MTF-Graphs present calculated values that don’t bear in mind manufacturing tolerances and pattern variation, so the precise efficiency within the area might range.

Focus Shift

33% crops, A7rII

I don’t see any focus shift right here and we are able to additionally see that this lens is healthier corrected for nearer distances than the Nikon AF-S 24mm 1.4G and the Canon EF 24mm 1.4L USM II.  

infinity (42mp Sony A7rII)

Typically the performs I see right here within the area matches what I see within the MTF graphs: the middle appears to be like good from f/1.4, however midframe and corners are a bit comfortable and it takes stopping all the way down to f/5.6 for optimum throughout body efficiency.

The Nikon AF-S 24mm 1.4G appears to be like a bit worse within the corners at wider apertures, however by f/5.6 appears to be like just about the identical. The Canon EF 24mm 1.4L USM II I attempted by no means regarded nice within the corners. The Sony FE 24mm 1.4 GM appears to be like fairly nice already from f/1.4 although.

As that is lens includes a floating components design the proper flange focal distance is essential for optimum efficiency. I examined this lens with a metabones in addition to a Sigma MC-11 on the Sony A7rII and each gave the identical outcomes. The Sigma MC-11 is usually nearer to the proper size than the metabones.

portrait distance 0.9 m (42mp Sony A7rII)

For portraiture it isn’t so essential how flat the sphere is, it’s extra attention-grabbing to see what the sharpness is like when targeted at completely different components of the body to take area curvature out of the equation.

That is what I did right here, I refocused for each shot and aperture to get the absolute best end result at completely different areas within the body (heart, internal midframe and outer midframe).
Focus distance was roughly 0.9 m and the circle of the greenback invoice is kind of the dimensions of a human eye.

f/1.4 <————> f/2.0

Sony A7rII | Zeiss 25mm 1.4 Milvus | 100% crops

On this class I might have hoped for an enchancment over the Nikon AF-S 24mm 1.4G and the Canon EF 24mm 1.4L USM II, however this isn’t actually the case.

This Zeiss 25mm 1.4 exhibits very excessive distinction and backbone within the heart of the body, however already the internal midframe space and particularly the outer midframe space is noticeably softer. Additionally stopping all the way down to f/2.0 doesn’t actually remedy this.

Each, the Nikon AF-S 24mm 1.4G and the Canon EF 24mm 1.4L USM II, have barely decrease efficiency within the heart of the body, however look higher within the midframe space which is one thing I would favor for my form of capturing. 

shut 0.25 m, 1:4.6 (42mp Sony A7rII)

100% crops from heart, A7rII

As I already prediced within the Focus Shift part this Zeiss lens does carry out very effectively at nearer distances. Right here the Nikon AF-S 24mm 1.4G is fairly comfortable and must be stopped all the way down to f/2.8 to match the Zeiss’ efficiency and in addition the Canon EF 24mm 1.4L USM II is softer at its most aperture.  

Flare resistance

As all the time evaluating flare is a posh matter since you may get any lens to look dangerous should you push it laborious sufficient and a slight change of situation can have an effect on outcomes loads. The late Zeiss lenses I attempted have usually been fairly good performers right here although – particularly the Zeiss 28mm 1.4 Otus.

Sony A7rII | Zeiss 25mm 1.4 Milvus | f/1.4

At f/1.4 we are able to solely see some minor artefacts and capturing instantly into the solar additionally the distinction stays on a excessive stage.

Sony A7rII | Zeiss 25mm 1.4 Milvus | f/11

Stopped down some points come up, as we might encounter moderately large artefacts and in addition veiling flare with a robust level mild supply near the nook of the body might be a problem.

From a contemporary excessive efficiency Zeiss lens I anticipated a bit higher on this class, it’s nonetheless higher than what I’ve seen from the  Nikon AF-S 24mm 1.4G or the Canon EF 24mm 1.4L USM II, but additionally clearly worse in comparison with the Sony FE 24mm 1.4 GM and the Zeiss 28mm 1.4 Otus.

Coma

100% crops from excessive nook, targeted on heart, A7rII

Correcting Coma in a quick extensive angle lens like it is a actually tough process. As this Zeiss 25mm 1.4 Milvus includes a extra advanced design than both the Nikon AF-S 24mm 1.4G or the Canon EF 24mm 1.4L USM II, I hoped it might carry out noticeably higher on this class. It does in reality carry out a bit higher, however then not likely sufficient to jot down dwelling about – particularly considering this Zeiss lens exhibits the very best vignetting figures.
In case you are in search of a quick ~24mm lens with good Coma correction finest take a look on the Sony FE 24mm 1.4 GM, which performs method higher than all of those DSLR designs.

Distortion

Sony A7III | Zeiss Milvus 25mm 1.4 | f/4.0

The Zeiss 25mm 1.4 Milvus solely a low to medium quantity of barrel distortion. A correction profile in Lightroom is on the market, however in lots of instances I discovered its correction too robust, setting it to 70% labored higher for me.

Bokeh

These quick extensive angle lenses are a bit difficult to make use of for shallow depth of area images, as you might want to be near your topic for that and you then typically must work round their perspective distortion.

Shut Distance

In shut focus situations the bokeh is usually good, much like the Nikon AF-S 24mm 1.4G. All lenses on this class additionally focus equally shut.

Mid Distance

Mid distances are what I like to make use of lenses like this for probably the most, as a result of you’ll be able to present your topic (e.g. an individual) but additionally its barely out of focus environment (see: : Create Environmental Portraits). The bokeh appears to be like once more much like the Nikon AF-S 24mm 1.4G and in addition the Sony FE 24mm 1.4 GM. The Canon EF 24mm 1.4L USM II regarded a bit busier in my testing.

Lengthy Distance

At longer focus distances a large angle lens will merely not yield as a lot bokeh as an extended lens with the identical most aperture, that means it will likely be tough to create a shallow depth of area. Right here with advanced backgrounds the bokeh additionally doesn’t look that good anymore.

If you wish to use this lens at wider apertures e.g. for capturing interiors with out a tripod you additionally should be cautious ensuring that each one the belongings you wish to be in focus really are.

Sunstars

Sony A7rII | Zeiss 25mm 1.4 Milvus | 50% crops

Identical to the Zeiss 28mm 1.4 Otus additionally this Zeiss 25mm 1.4 Milvus options an aperture diaphragm fabricated from 9 rounded aperture blades. The alignment of the blades is fairly good, so we see respectable 18-pointed sunstars with rays of even size from f/8.0 to f/16.

Chromatic aberration

lateral

Sony A7rII | Zeiss 25mm 1.4 Otus | f/11 | 100% crops

Just like the Zeiss 28mm 1.4 Otus additionally right here we see a medium quantity of lateral CA right here. That is nonetheless simply corrected in put up by only one click on, so nothing to fret about. 

As soon as once more we now have to speak about expectation managment right here.

Going by its optical diagram, dimension, value and launch date, I hoped this Zeiss 25mm 1.4 Milvus could be shut in efficiency to the Zeiss 28mm 1.4 Otus. Having used each lenses beneath the identical situations in the identical situations, I’ve to say that’s not solely the case.

Regardless of solely that includes yet another lens ingredient, the Otus corrects Coma higher, has decrease vignetting figures, higher flare resistance, higher sharpness and in addition creates a nicer bokeh with larger high quality aspherical components. The Otus being even greater and heavier and – to not point out double the worth –  which may not be that a lot of a shock although, so how does it examine to the now less expensive DSLR alternate options from Nikon and Canon?

Typically, this Zeiss 25mm 1.4 Milvus performs a bit higher in a few of the classes, however sufficient to warrant double the burden and value whereas not that includes auto focus? I’ve my doubts about that.

This Zeiss lens additionally solely considerably is sensible should you want a lens with EF or F-mount. There’s a big benefit to designing lenses like this for mirrorless cameras and this turns into very apparent when trying on the Sony FE 24mm 1.4 GM, which exhibits a greater efficiency in just about each class whereas being cheaper and fewer than half the burden and dimension.

If you happen to additionally take into account a 28mm lens as an alternate options, the Sigma 28mm 1.4 Artwork, the Nikon AF-S 28mm 1.4E, the Nikon AF-D 28mm 1.4 and the Laowa 28mm 1.2 Argus are all a part of my Quick 28mm Comparability, so finest take a look there first. I additionally reviewed the Zeiss Otus 28mm 1.4 Apo Distagon.
