New Zenith lenses

zenith lenses coming
On the picture is a very old Zenith camera

Which Zenith lenses are coming ?

Seems Zenit comes back with three lenses, the Zenith 85mm f/1.2 the Zenith 50mm f/1.2 and the Zenith 50mm f/0.95 lenses. Zenith had some very popular lenses like the Jupiter 135mm f/2.8 is still used in Hungary by some or the Zenitar 16mm fisheye lens which was available in the US as well, and had a good reputation.

New Zenitar 50/0.95

This lens is designed for Sony FE mount cameras. Has many aperture blades, 14 if I remember well, in two different depths. The lens has a 72mm filter thread, the lens construction is 9 elements in 8 groups.

New Zenitar 50/1.2

This lens is designed for Full frame cameras. It will be available for both Canon EF and Nikon F mounts. Perhaps this will be the first lens released sometime this year. Currently it is a massive 1200g lens, Zenith is working on to make it smaller.

New Zenitar 85/1.2

It is also designed for Full frame cameras, with a design of 9 elements in 7 groups, has a 82mm filter thread, and metal mount. It will be available for both Canon EF and Nikon F mounts.

Price and release date is not yet known of these lenses (some projected for 2017), but according to some information the lenses will not be more expensive than 600 USD.

Zeiss Batis 18mm f2.8 for FF Sony E mount

Zeiss Batis 18mm 2.8
Seems Zeiss actively take part of the Sony E mount lens construction. The widest lens is coming in the form of the Zeiss Batis 18mm f/2.8 lens. The wide 18mm focal length is very popular among landscape photographers.

The other lenses in this family is the Zeiss Batis 25mm f/2 and the Zeiss Batis 85mm f/1.8 lenses. The other two lenses look very interesting as well. The 85mm is for portraits, the 25mm is also for landscapes and general photography.

All three lenses has wide apertures which makes them more useful in low light or night photography.

These are all autofocusing lenses on the Sony E mount Full frame cameras (most Zeiss lenses are manual on other mounts, like Canon and Nikon).

Sony 70 300mm G OSS

(1450 EUR, Sony FE mount)
Sony 70 300 G OSS
A new telephoto lens from Sony is on its way. This is a tipical, very useful reach in photography, especially for portraits or distant landscapes. Most manufacturers uses these types of lenses as a step up (better than the cheapest, but not really satisfy an advanced amateur), but there are more serious versions as well. The problem with these lenses is the soft 300mm setting. Otherwise who would buy super expensive 300mm primes ? I found the 70 300mm focal length is quite useful, but yet to see a sharp 70-300mm at 300mm. The sharp aperture is another story. I would be interested in an ideal word how these lenses would look like.

I do not say that this Sony is like this. The steep price tag (1450 USD) suggests it is designed to be better. Perhaps it is sharp all the way, wide open. On product images the lens looks really reassuring not like the above mentioned plastic wonders. The lens has an Optical Steady shot stabilizer and sealed against dust and moisture. The lens has a focus hold button can be used to stop the autofocus system when it is required.

irix 15mm f2.4
This is the lightweight firefly version of the Irix lens

A new Swiss Korean optics is on the Horizont. The company name is TH Swiss, which seems manufacturing the manual focusing, full frame lens in Korea. That seems quite unusual. According to the specification it can be a very interesting lens. The filter size is 95mm, the lens has 15 elements in 11 groups, the minimum focus distance is 0.28mm (1′). “The photographers dream lens is built by engineers and perfected by designers”

There are to versions: a Firefly and the Blackstone. One of them is built like the Tank the other is the “Lightest in category”. The lens is optimized for 50+ megapixel sensors according to the manufacturer, has neutrínó coating, and clicks at infinity focus. The lens has a focus lock, which allows to fix the focus ring at any point, and the lens has sealing against dust and moisture.

The Firefly version of the lens has a broader focusing ring.

The manufacturer offers several own ND filters as well as a separate accessorie to the lens for extra money.

Video about the Irix 15mm f2.4 Blackstone and Firefly lens

No price information yet, my guess it won’t be cheap. The blackstone version will be more expensive because of the alu construction. According to some sources the price will be 475 EUR for Firefly and 695 EUR for the Blackstone version.
