My Digitals

The Zeiss Batis

 

 

After using Zeiss Otus, it will be very hard for you to consider using other lenses even Zeiss. The best in quality you can get. However, weight sometimes can be an issues and I am glad that I have found my solutions: The light weight and autofocus Zeiss Batis series of lenses. Not being a fan of 35mm and 85m focal length, I collected the Batis 18/2.8 Distagon, 25/2 Distagon, 40/2 CF Distagon, and 135/2.8 Apo Sonnar. All of them are of very good quality, able to autofocus on Sony A7, and best they are not very heavy to carry around. Some people will complaint that the Batis are too big in size but that is not an issue for me. 40/2 is close to 35mm, but I still consider this one because it can be used as the only lens if I were to go out with just one lens (my ZM 35/2 can also do the job but it is manual focus and no EXIF data). Also the 40/2 CF has close focusing capability probably around 1:3 so a good candidate for occasional macro use.

The High Quality and Versatile Long Range Zoom

 

 

 

 

Too much has been said about this fantastic G Master zoom. This lens has very outstanding image quality and a very useful tele zoom range of 100-400mm, which I personally find more useful than 70-200 (although the G MAster 70-200 is faster a f2.8 throughout the zoom range) for most events shooting.

The 100-400 is compatible with the two teleconvertors SEL14TC (1.4x) and SEL20TC (2x). Most of the time I would prefer to use the 1.4x, and only under sitaution that I have no choice then I will consider the 2x.

The following two also shot with TC1.4, but quite desperate so used A7R2 in APS-C mode to crop further.

Enlarger Lens for Macro

I bought the Schneider Componon-S 100/5.6 enlarger lens quite a while ago sitting in the dry cabinet. After trying the SL66 120/5.6-bellow set up I find it too heavy and suddenly thought of this enlarger lens set up. The 100/5.6 can be used with the Rollei bellow very conveniently and is a very light weight macro set up for very close up photography. 

 

Of course I have my very high quality macro lenses like the 60/2.8 Makro Planar and the 100/2.8 Makro Planar. But from specification point of view the SL66 120/5.6 MTF shows better lens performance for magnification larger than 1:5. So I think it will be the same for the Componon-S. The 100/5.6 comes with a lever to open or close the aperture, and also to set the aperture either in steps adjustment or smooth adjustment. The lens comes in M39 screw mount, so to use on the Sony Alpha 7 it will need a M39-M42 adaptor and a M42-FE adaptor. In this case I am using a Rollei QBM bellow and thus a M42-QBM and QBM-FE adaptor. The bellow will allows very easy framing and focusing of the lens as the 100/5.6 does not come with a focusing helicoil.

Auto Focus Zeiss Sonnar

Finally, the first auto focus lens I buy and use in my life, and happens to be the hot from oven Zeiss Batis 135/2.8 Apo Sonnar T* for Sony FE mount. Full frame, Apo design, auto focus!

 

 

Below is a simple illustration of the evolution of Zeiss 135mm f2.8 over the years, less the very respectable Contarex 135/2.8 Sonnar.

In old days Zeiss lens designs are always very elegant, making use of very few lens elements and groups. From an engineer point of view the simplest design is the best and most elegant design. But today with very high resolution digital sensors even Zeiss will need to make their design fairly complicated to cater for much stringent performance requirement and the do-not -quite-make-sense pixel peeping on the computer screen. For telephoto the unavoidable CA and colour fringing, and for Batis design for auto focus. Thus you can see the fairly complicated Apo Sonnar design for the Batis series, and knowing Zeiss has been very stingy on labelling their lens as Apo you would thus expecting very high standard of correction for the Batis 135/2.8 Apo Sonnar, and of course with the renown T* multi-coating. Based on the lens diagram I think the Batis Apo Sonnar is no longer a conventional Sonnar design, as the design now need to cater for very high correction of images and also internal focusing for auto focus. The lens design used floating elements, but Zeiss only uses special glasses for this lens and no aspherical elements to achieve the Apo quality.

Competing head on of course is the very good ZF/ZE series 135/2 Apo Sonnar T*. The Batis is lighter, and being internal focus the length of the lens does not change over different focusing distance. Based on the MTFs both Apo Sonnar performance is very good. My only complaint on the Batis is the fine focusing. For that it could be the focus by wire manual focusing design of the Batis, or I have not get used to this method of manual focusing. Although the Batis Apo Sonnar is the heaviest 135/2.8 from Zeiss so far at 614g, when mounted on the A7R2 the package feels very comfortable and manageable, especially I have been using Otus lenses with the A7R2 hahaha!

It could sounds funny, that the very first thing I tried to do with the Batis 135/2.8 is to figure out how to best manual focus the lens  : D !! Next is of course struggling very hard for the whole day in a school event of my daughter to figure out all the auto focus settings on a Sony A7R2!

And till the night I was trying the various auto focus settings for moving subjects on stage, and finally I think I have made the auto focus mode work for me and also being quite far from the stage I happened to be able to examine the high resolution and high correction for the Batis 135/2.8.

The photo was taken with the A7R2 mounted on a tripod with the Batis Apo Sonnar. Taken at f2.8 the widest aperture and at ISO 1250. The crops of the photo demonstrate very clearly the very high quality of the Apo Sonnar and also the A7R2.

 

No regret, and I will have more fun with the Batis Apo Sonnar in the future!

ZF 25/2 Distagon T*

The All Round Wide Angle

This well designed and fast wide angle is my interim from the ZM to the Otus. The ZM 25/2.8 and ZM 28/2.8 are very good but unfortunately cannot be used on Alpha 7 for all shooting situations. The Rollei and Contax wide angles like HFT 25/2.8 Distagon, CY 28/2.8 Distagon T* and CY 28/2 Distagon T* all actually work very well on the Alpha 7 series of bodies, which shows that Zeiss makes lenses of very high quality. These old lenses can perform very well even in the digital age, only suffer slight drop in sharpness towards the edges of the photo as they are not design for digital sensors in the first place. In the good old film days, when you take group photos you only need to focus the people approximately and with aperture f5.6 or f8 you will get very sharp photos with all the faces in proper focus. However, in the digital age the sensors are so much more picky and for group photos you have to focus carefully even at aperture of f5.6 or f8. For me I will tend to focus the faces in the front row, and since the depth of field will expand to the back more than to the front, everybody will become sharp. If you focus on the back rows there are very high chances that the front row will not be sharp enough when you view the shots on computer.

The ZF 25/2 Distagon T* is very good, and very hard to fault, other than the CA in some situations where only Otus 28/2.8 Apo Distagon will managed well. But the Otus 28/2.8 is very huge, heavy and expensive. So the ZF 25/2 is a very good alternative and it is very fast at f2 also and can use for a lot of photography opportunities. I finally bought the Otus 28/1.4 and the ZF 25/2 will be for the occation where I am not able to bring the Otus due to its size and weight. But it is strange up to this point of time that there are no 25mm and 28mm in the Zeiss Loxia series and Milvus series but there is a 25/2 for the autofocus Batis series.
