Thus far TTArtisan largely launched quick but compact M-mount lenses, probably the most well-known most likely being their 50mm 0.95. These lenses typically emphasised pace and measurement over sharpness, however now we’re getting one thing completely different: the TTArtisan 35mm 2.0 Apo-Aspherical. Going by the specs it is a direct competitor to the Voigtländer VM 35mm 2.0 Apo-Lanthar, however does it additionally play in the identical league? Let’s discover out.
This lens might be reviewed on the 42mp Sony A7rII and the 24mp Leica M10.
Many of the pattern photographs on this evaluation could be present in full decision right here.
Up to now TTArtisan typically added completely different mount choices to their lenses later, however up to now this lens solely is available in M-mount and has the next specs:
- Diameter: 55 mm
- Subject of view: 63.6° (diagonally)
- Size: 82 mm
- Weight: 510g (with hood)
- Filter Diameter: 52 mm
- Variety of Aperture Blades: 10 (inwardly curved)
- Parts/Teams: 12/9
- Shut Focusing Distance: 0.7 m
- Most Magnification: 1:16.8 (measured)
- Mount: Leica-M
The TTArtisan 35mm 2.0 AA was kindly offered freed from cost by TTArtisan for reviewing goal for a length of 4 weeks.
Dealing with / Construct High quality
The TTArtisan M-mount lenses produced by DJ-Optical didn’t disappoint on this class up to now (apart from the 28mm 5.6).
From the outer apperance this 35mm lens seems very very similar to a Leica M lens together with the well-known pink dot. Markings are yellow/white (engraved and crammed with paint), the main target ring has good resistance and turns about 120° from the minimal focus distance of 0.7 m to infinity. The main target ring can be outfitted with a spotlight tab.
The aperture ring has equidistant and really distinct half-stop click on stops, feels very tightly assembled and is a pleasure to make use of.
The lens got here with a correctly calibrated onerous infinity cease and likewise at nearer distances it was effectively calibrated. Not like most of the different TTArtisan lenses it seems like this one can’t be simply adjusted your self although.
The TTArtisan 35mm 2.0 AA brings up the right 35mm framelines, however the viewfinder blockage is important. It’s not an inside focus design, so the blockage will get worse as you focus nearer.
There’s a rectangular hood with gap for the rangefinder included within the package deal this time and it’s connected in the identical method as a few of Leica’s lens hoods (e.g. these of the 35mm 1.4 FLE or the 16-18-21mm 4.0) that means there’s a small rubber ring to place it underneath stress so it stays in place when totally screwed in.
With out the hood connected it additionally seems like there’s clearly one thing lacking, so this is likely one of the lenses the place I might at all times be utilizing the hood.
What can be notable is the dimensions of this lens. At 510g it’s the heaviest and from the outer dimensions additionally the largest 35mm M-mount lens I do know of, even trumping the Zeiss ZM 35mm 1.4. This coupled with the minimal focus distance of 0.7 m is a transparent drawback in comparison with the Voigtländer VM 35mm 2.0 Apo-Lanthar (304g, 0.5 m MFD) and the unobtainable Leica 35mm 2.0 Apo-Summicron (320g, 0.3 m MFD).
This 35mm 2.0 is roughly the identical measurement because the Leica 90mm 2.0.
On the Leica M10 I additionally had points with unmounting the lens when it wasn’t set to infinity.
Now that is attention-grabbing. Vast open I measure nearly 2 EV nook shading which is about 1 EV higher than the Voigtländer VM 35mm 2.0 Apo-Lanthar. What can be attention-grabbing: stopping all the way down to f/2.8 improves this to round 1.6 EV however stopping down additional doesn’t change this worth in any respect.
It is strongly recommended to take a look at this text first to get an thought how this brightness graph works.
A 35mm lens with a most aperture of f//2.0 isn’t a lens the place I might anticipate a big quantity of optical vignetting.
However we can have a more in-depth look, 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.
We will be taught 3 issues from this:
- Optical vignetting is low
- The straight aperture blades result in decagons already at f/2.8
- The sharpening of the aspherical ingredient is basically tough, as we see extreme onion ring constructions
infinity (42mp Sony A7rII)
Lenses this advanced and excessive resolving are finest used on the digital camera sensor they’re designed for, so we must always anticipate some decreased nook decision when utilizing this lens on the thick Sony filter stack if it has been designed for the thinner Leica filter stack..
Nonetheless, on a Sony digital camera we see superb heart and midframe decision from f/2.0 and whereas the corners by no means attain that degree, they nonetheless look good from f/4.0. So apparently this TTArtisan 35mm 2.0 M-mount lens performs higher on E-mount cameras than the Voigtländer VM 35mm 2.0 Apo-Lanthar (however in fact worse than the E-mount verison of the Voigtländer).
However let’s take a look how the lens performs on the Leica M10 within the subsequent part.
infinity (24mp Leica M10)
Contemplating the advanced design of this lens I anticipated efficiency rivaling the Voigtländer VM 35mm 2.0 Apo-Lanthar when used on the Leica M10. Whereas that is actually true for heart and midframe, the corners of the TTArtisan lens do profit from stopping down a bit.
Perhaps their lens designer went for an “common” filter stack thickness throughout the design which might clarify why it performs higher on the Sony A7rII however worse on the Leica M10 (in comparison with the Voigtländer VM 35mm 2.0 Apo-Lanthar) so that they don’t must design separate lenses for various digital camera programs like Cosina did for his or her Apo-Lanther lenses.
portrait distance 1.0 m distance (24mp Sony A7III vs 24mp Leica M10)
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 subject curvature out of the equation.
We might be 100% crops from the 24mp Sony A7III and the Leica M10. Each cameras do not need an anti aliasing filter in entrance of the sensor.
Sony A7III <—> Leica M10
At a spotlight distance of 1.0 m the lens performs actually nice by way of sharpness and there are solely minor variations in efficiency between the cameras seen.
shut (0.70 m, 1:16.8, 42mp A7rII)
100% crops from heart, A7rII, due to focus shift (see corresponding part) I refocused for each shot.
A minimal focus distance of 0.7 m is a bit lengthy for a 35mm lens however nonetheless typical within the M-mount world. Nonetheless, many of the Voigtländer 35mm lenses focus all the way down to 0.5 m and the newest Leica 35mm 2.0 even focuses as shut as 0.3 m.
Coming again to the TTArtisan 35mm 2.0 there’s hardly any softness on the most aperture seen, so I wouldn’t hesitate to make use of f/2.0 at shut distances in any respect.
Evaluating flare is a posh matter since you may get any lens to look dangerous if you happen to push it onerous sufficient and a slight change of state of affairs can have an effect on outcomes so much.
Only recently I reviewed the TTArtisan 50mm 2.0 which carried out very dangerous on this class. So let’s hope this 35mm lens is doing a greater job.
Solar outdoors body
A powerful level gentle supply outdoors the body can result in a little bit of veiling flare (lack of distinction) in addition to just a few smaller ghosts.
With most lenses there’s a very particular place near the nook of the body that can result in an enormous flare and the TTArtisan 35mm 2.0 AA isn’t any exception, however that is one thing simply prevented by a slight reframing and never one thing you’ll encounter typically within the subject.
Solar inside body

With the solar contained in the body a hoop flare can seem at wider apertures that goes away on stopping down.
Sony A7III | TTArtisan 35mm 2.0 AA
I took many photos with a robust gentle supply within the body with none points (see the pattern photographs), however now and again you’ll catch some artefacts.
Usually the Coma correction is nice, however there’s one other problem that’s seen right here: radial streaks round level gentle sources that don’t go away on stopping the lens down.
My first guess was that it’s tangential Astigmatism, however I’ve by no means seen this aberration to such a excessive diploma in any lens I’ve reviewed earlier than and the decision stopped down typically is basically good – if it was Astigmatism this shouldn’t be the case.
100% crops from excessive nook, targeted on heart, Leica M10
My present guess is that that is because of the very tough sharpening of the aspherical ingredient. The deep radial cuts might result in this impact and this could positively be a difficulty for blue hour taking pictures.
Distortion is hardly seen, however there’s a slight waviness near the borders. However, even for structure photos I by no means felt the necessity to right it.
In terms of 35mm lenses a most aperture of f/2.0 isn’t that thrilling anymore, as as of late now we have a very excessive resolving f/1.2 lens with autofocus, a compact M-mount 35mm f/1.2 lens and even an f/0.95 guide focus lens.
However on the subject of bokeh there’s not solely amount, there’s additionally high quality and the low optical vignetting offers me a little bit of hope right here.
A minimal focus distance of 70 cm isn’t that nice for a 35mm lens. What I like right here is the very even bokeh although, which seems very pure to me due to the absence of strange shapes within the corners. In comparison with the Voigtländer VM 35mm 2.0 Apo-Lanthar the bokeh can be much less busy/contrasty.
With defocused level gentle sources within the body onion ring constructions because of the tough sharpening of the aspherical ingredient can grow to be seen although. Additionally, you will be capable to spot this when taking a look at among the forest photos in greater decision.

The pattern continues at medium distances. I really don’t keep in mind the final time I’ve used a lens that offers this even bokeh from heart to corners at its most aperture.
Longer focus distances are the place issues get attention-grabbing. When utilizing compact lenses with excessive vignetting and unfavourable subject curvature it typically occurs that the corners are noticeably much less out of focus than the central a part of the body.
This isn’t the case right here. Additionally at longer distances the bokeh seems very pure and undistracting to me. In case you are a type of not after bragging rights of getting the quickest aperture written on the lens, however after an excellent and pure look this lens is likely to be for you.
The TTArtisan 35mm 2.0 AA makes use of 10 straight aperture blades, which could be excellent news for sunstars, however as we all know not solely form and quantity but in addition the standard of alignment of the aperture blades is detrimental. At wider apertures we see somewhat fuzzy sunstars, it really takes stopping all the way down to f/16 to see distinct ones.
If you wish to know extra about sunstar rendering of various lenses take a look at this text.
I checked the amout of lateral CA and they’re so near zero I’ve nothing to indicate you right here.
An Apo tag is well printed on a lens or its field, however solely only a few lenses really provide a totally apochromatic correction. I used to be particularly upset by the 2 Voigtländer 35mm 2.0 Apo-Lanthar samples I reviewed, as their correction was not so good as I might anticipate to award an Apo designation.
The story could be very completely different right here, the TTArtisan 35mm 2.0 is completely corrected. There isn’t any bokeh fringing seen in any respect.
Sony A7III | TTArtisan 35mm 2.0 AA | f/2.0
Some lenses fare effectively on the subject of traditional loCA however fail on the subject of purple fringing, but in addition right here the correction is totally flawless. We’re coping with a real Apo design.
Sony A7III | LM-EA9 | TTArtisan 35mm 2.0 AA | f/2.0
50% crops, A7rII
With some lenses when stopping down the airplane of optimum focus shifts to the again or the entrance. Sadly the TTArtisan 35mm 2.0 is considered one of these lenses.
The soar between f/2.0 and f/2.8 is a big one. Utilizing the lens at shut distances this could grow to be a difficulty when counting on the rangefinder to focus.
At longer distances or so long as you cease down first and focus afterwards with the assistance of liveview this won’t be a difficulty.
I reviewed loads of 35mm M-mount lenses. The obvious competitor is the Voigtländer 35mm 2.0 Apo-Lanthar which is available in each, M-mount and E-mount variations. They’re noticeably smaller and lighter but in addition dearer. The TTArtisan lens may also be the higher selection if you’re utilizing M and E-mount cameras concurrently, or if you’re on the lookout for a 35mm lens for use with a Techart AF adapter.
Different notable 35mm M-mount lenses are the Voigtlander VM 35mm 1.7 (if you’re on the lookout for a smaller/lighter possibility with good bokeh however barely worse picture high quality), Voigtlander VM 35mm 1.2 III (if you’re trying extra for pace than sharpness) or Zeiss ZM 35mm 1.4 (superb sharpness in an f/1.4 lens). What I didn’t evaluation is one other the direct competitor, the Leica 35mm 2.0 Apo Summicron-M, primarily as a result of it’s roughly $8000.
For those who ended up right here by chance and also you wish to have a basic overview over the 35mm E-mount lenses take a look at our somewhat complete information on 35mm lenses for Sony FE cameras.
When it come to the optics it is a high quality lens certainly: excessive distinction and backbone mixed with pure and undistracting bokeh (additionally as a consequence of comparably low optical vignetting) is at all times one thing I discover very likable. And it is a true Apo design, so there is no such thing as a colourful outlining to be discovered wherever. Add to that the very good construct high quality – the TTArtisan M-mount lenses are amongst my favorites – and we must always have an actual winner, proper?
The Leica customers are often measurement and weight aware folks although and I’m not certain a lot of them like the thought of a 35mm f/2.0 lens as large and heavy as this one. In spite of everything, the Zeiss ZM 35mm 1.4 is usually being scolded for being too large and heavy, but it’s noticeably smaller and lighter than this TTArtisan 35mm 2.0 right here – regardless of being a full cease sooner. So in that regard the TTArtisan 35mm 2.0 may really be a greater match to different fullframe mirrorless cameras.
My pattern additionally had a really roughly polished aspherical ingredient. I’m not certain if this was an outlier or if they’re all like that, however as proven within the Coma part it seemingly results in some surprising points. I hope to see some extra stories on this lens to see if this one’s aspherical ingredient was an outlier or somewhat what’s to be anticipated.
Now on the finish of the day this TTArtisan 35mm 2.0 Apo-Aspherical prices 40% of its direct competitor, the Voigtländer VM 35mm 2.0 Apo-Lanthar, and it its parade self-discipline – apochromatic correction – even beats it. I additionally worth the pure bokeh rendering greater than the higher nook sharpness at wider apertures. However within the M-mount 35mm world it is a brick of a lens.
Many of the pattern photographs on this evaluation could be present in full decision right here.
My title is Bastian and I’m your skilled right here on the subject of extremely huge angle lenses, tremendous quick portrait lenses (starting from a 50mm f/0.95 to a 200mm f/1.8) and I even have reviewed method too many 35mm lenses.
Do not ask me something about macro or wildlife taking pictures although.
