Zeiss Batis 40mm f/2 CF Review - Performance

Zeiss Batis 40mm f/2 CF Performance

As surmised by the generous diameter of the image field, centre and edge performance is very close indeed. In both cases, sharpness is excellent from f/2 right through to f/11 and very good from f/16 to f/22. We have a lens here where even the f/22 setting is totally viable and available for extended depth of field, without compromising quality.

How to read our MTF charts

The blue column represents readings from the centre of the picture frame at the various apertures and the green is from the edges.

The scale on the left side is an indication of actual image resolution as LW/PH and is described in detail above. The taller the column, the better the lens performance.

For this review, the lens was tested on a Sony Alpha A7 III using Imatest.


CA (Chromatic Aberration) is approaching zero at both centre and edge, a remarkable performance. This means no visible colour fringing, even in the most demanding circumstances, such as branches against bright sky.

How to read our CA charts

Chromatic aberration (CA) is the lens' inability to focus on the sensor or film all colours of visible light at the same point. Severe chromatic aberration gives a noticeable fringing or a halo effect around sharp edges within the picture. It can be cured in software.

Apochromatic lenses have special lens elements (aspheric, extra-low dispersion etc) to minimize the problem, hence they usually cost more.

For this review, the lens was tested on a Sony Alpha A7 III using Imatest.

 

We can measure -0.13% barrel distortion, but that is insignificant and the lens is effectively perfectly rectilinear. Architectural subjects will be rendered with complete accuracy.

The rounded diaphragm and lens design have also resulted in very pleasant smooth bokeh, the gradation of the out of focus areas in an image. This is something that equates with the feel and character of a lens. It is part of the indefinable qualities that make a good lens a great lens.

Flare was simply absent. The coating is clearly highly efficient and flare could not be induced.

Some vignetting is present, starting off at around -1.5 stops of corner darkening at f/2. This reduces to -1.3 stops by f/2.8 and thereafter is -1 stop throughout the range of apertures. This is well within expected parameters for a modern lens design and indeed a tinge of corner darkening can often help an image. It will be difficult to spot this degree of vignetting, though, in normal circumstances.

Overall, this is a very strong performance and a very fine lens.

What's remarkable is the new Tamron 17-35 Di OSD tested a few weeks ago has actually bettered the Zeiss performance in the F4, 5.6, f8, and f11 areas, also better chromatic aberration control!!

There are certainly some great lenses out there for us to choose from!

No really, the Tamron was tested on a Nikon D810 (36mp) versus the Zeiss on a Sony A7 III (24mp). Put the Zeiss on a Sony A7R III would give us a better indication and I'm willing to bet, a better performance than Tamron.

Exactly, the Tamron has already been tested on a high res 36 mp camera, so more exacting than the A7III, I am not disputing the Zeiss will be a lovely well-built lens, but the Tamron is a bit of a bargain. I have sold my Nikon 16-35 VR f4 because the Tamron blew it away in the corners at all apertures and matched and in some cases bettered my Irix 15mm 2.4 which in many tests has held its own against similar Zeiss lenses.

What a pitty that horrible bokeh at f2.0. Except that it's magnificent!

Sad that this beautiful has has to carry all that crap dust and fluff around on it's zoom ring. What genius chose that material.

Quote:Zeiss own web site states quite clearly this lens, like most Zeiss lenses is made from metal, NOT polycarbonate. Don't cheapen there products with misinformation, thank you.


We don't say that it's polycarbonate? So not sure why you think we do?

Testing such a high quality lens on the 24mp sensor is pretty much useless... Why don't you always use the sensor with the highest resolution? This would show that some lenses are great at 42mp and others are clearly designed for the 24mp cameras.
