I am 3 days into my ownership of the Meyer Görlitz Orestor. Already now is it clear to me that this is perhaps the most intriguing lens I ever owned. Continue reading Das Objektiv, Meyer-Optik Görlitz Orestor 2.8 135mm (3)
If you followed my last blog posts on using inexpensive lenses like the Carl Zeiss Jena 35 on my A99V you might have been wondering on how to make it fit. The way you pull this off is with a M42 to A-mount adapter. The adapters is fairly inexpensive, ranging from a flat piece of thin piece of metal with a Sony/Minolta A-mount bayonet fitting and a threaded opening for a M42 lens to .. yes the same with confirmation chip glued to them.
The benefit of using the slightly more expensive chipped versions is that the confirmation chip communicates with the camera, telling it that there is a real Sony lens attached. The camera then reads the information from the chip, and applies this knowledge when it determine how to react. The direct effect is that camera will let you use Aperture Priority automatic exposure, so you can select the aperture and the camera will select an appropriate shutter speed. The draw back is that you cannot just use any chipped adapter with any particular lens. The chips information on focal length has to correspond with the lens focal length and f/stop. That’s why I usually end up using a cheap non-chipped adapter, where I can use any M42 lens.
I got 5 different adapters, and each just slightly different in thickness. The cheaper versions has no chip but to be honest it is not the chipped I prefer. You might also be able to see that one of my adapters was a few thousands of an inch to thick. Causing the lens to move too far away from the focal plane, with the loss of infinity focus as an result. The problem got solved by sanding the adapter until it brought the lens close enough to the sensor to focus at infinity. My Chipped Lenses tells the camera that a 50mm f/1.7 lens is attached to it, only problem that its rarely the case.
The adapter attaches neatly to the camera, and is almost invisible once the lens is attached.
Your are about to step into a world of inexpensive, high quality M42 optics. Lenses for this mount has been produced for more than 70 years. There is communities on Facebook that offers clean and restoration of lenses if needed. All it takes is that you are willing to forget modern convenience, become a better photographer by mastering your camera in total manual mode and forcing yourself to think carefully about each frame.
Word of warning
Be very careful when selecting a lens, even though T mount lenses also is 42mm, is not the same, forcing it can result in damage to either the lens or the adapter.
Some lenses has a aperture pin which comes dangerously close to the mirror or connector pins in the A-Mount. On any account this pen has to be pushed down since the aperture control won’t work unless the aperture pin is pressed. For me the solution has to super glue this pin.
‘back to the future … Part 1
Tthe Carl Zeiss Jena Flektogon (CZJ) is an old lady, produced between 1955 and 1961. It has 6 elements which is placed in 5 groups.
its imperfections gives a wonderful potential. I am of cause talking about how it is prone to flair, how depth of field lens effects the light and gives crazy Smooth Bubbles. The lens is produced in different versions, this one has 9 aperture blades, but there is rare versions with 12 blades as well. Great center sharpness and it’s really sharp all over from f/5.6 and above.
I like the fact that this lens is prone to lens flare, for some it might be seen as an undesirable effect on the image. I see it differently, for me it is often the element that brings emotion to my picture. It could be an effect of romance, life, depth. My advice is to seek to use them deliberately, rather than being annoyed by these what technically just is diffraction artifacts. It is true lens flare can show itself in more than one way, as long as it only manifests itself as visible artifacts in the shape of the lens iris then I do not mind. It can also appear as a haze across the image and in such situations am I the first to head down in my camera bag to retrieve a lens hood to avoid that washed out look with reduced contrast and color saturation. Diffraction artifact becomes especially interesting in digital cameras, When the sun is shining on an unprotected lens, a group of small rainbows appears. This artifact is formed by internal diffraction on the image sensor, which acts like a diffraction grating.
Using the CZJ 35mm f/2.8 with a extension tube
Extension tubes is perhaps one use-scenario which I had overlooked the most, and which I am totally nuts about. All the qualities of the lens comes to life combined with a really close macro experience. Do notice how the understated colors is still in play, and the sharpness right on the money, not looking overly sharpened yet very well defined. This shoot of the flower is straight out of the camera, shoot handheld and with no postproduction with no Photoshop magic or cropping
I’ve had more people suggesting me to look into M42 bellows rather than using extension tubes, they usually sell for similar prices and give both greater flexibility and a wider range of magnification. I got my extension tube practically for free, but should I purchase one for the full price, my choice had possibly tipped the other way, while the bellows is both easier and more flexible to use. Finally, and not to be considered lightly, bellows are WAY cooler looking than tubes! Impress both friends and strangers!
the math is simple:
- magnification_change= extension_change/focal_length short lens = big magnification.
- working_distance_change = focal_length(1/new_magnification-1/old_magnification) long lens = big working distance.
Working with russian vintage lenses, broke me in on using vintage lenses on my Sony Alpha A99V camera. To my surprise was the quality of these old wonders amazing both in terms of sharpness and the way they treats light. Colors, Bokeh wow. Having seen the good light I wanted more, and I swapped myself to a Pentacon 135mm f/2.8. This lens is easy adaptable to the A-Mount while it has a M42 Mount.
When heading out on the vintage road, then the Pentacon 135mm 2.8 seems to be a good option. Let me start out with a word of warning, there is two editions of the lens, one cheap with 6 aperture blades and the original with 15 aperture blades, the last one is widely more popular among hipsters 🙂 , and therefore much more expensive than the newer edition. The more expensive 15 aperture blade is also known as the “bokeh monster”. It is softer wide open than the cheaper 6 blade version. Both of them offers a really nice bokeh. Both editions is manufactured in East Germany and are copies of a Carl Zeiss Jena. Optically they are identical, the lens i got is the cheaper version and it’s a very nice lens. It is reasonably sharp at f/2.8 but quickly getting sharper when stopped down.
The sharpness of the lens is undeniable, and comes over really clear. I usually use my Araucaria Araucana tree which stands proud in my garden. Light falls nicely in its sharp leafs. The colors stand very vibrant and well defined and look at separation qualities, this is what thrills me. The photo here is taken at a very overcast day, and the traditional bokeh bobbles isnt there.
Another flower I like to photo is a Peony which blossoms in my garden. Besides having very organic and interesting forms, then it has a deep red color. Usually with Minolta lenses the colors comes over too pinkish, but with this lens we are closer to the true color of the flower.
The bokeh of this lens is simply lovely, so round, simple and smooth. It makes bobbles almost without any effort from my side. To take this photo I placed a festoon hanging on my television (which also causes the strange double effect) the television and festoon is some 3 meters behind my subjects (the candles) and it bubbles so nicely, with a round and smooth bokeh. With intent is the bokeh not very busy, this gives the opportunity to enjoy how the forms is distributed over the image.
Moving the festoon in closer to my subject reveals why the 15 aperture blade edition is more sought after than the 6 blades. The form of the bokeh becomes a pentagon, and looses its smooth round form.
Here is another picture showing the difference in distortion over the photo.
And another one showing how sharp and well defined the lens can be. Look how well 3 dimensional the result becomes. Its simply outstanding.
Here is a shoot from Rebild bakker, Denmark. taken late in the day, handheld at f/2.8, I adore the bokeh of this glass, it has a very smooth expression. Its ability to separate the background from the motive is perhaps what I love the most of this piece. It is almost like fern is photo shopped onto the background.
From Thorup, near Fjerritslev, North Jutland in Denmark. An historical trade village on the northern coast. Today its fishing which is carrying the activity on these shoorts, and to this day fishing boats is still being hauled directly up on the beach. Thorup Strand is one of Europe’s largest coastal landing places, with up to 20 fishing boats.
Not far from Thorup is cliffs of Bulbjerg. Facing Skagerrak this limestone cliff the breeding place of the black-legged kittiwake. It is a wonderful place to bring your camera. This photo is a construct of 3 pictures, as i was shooting 135mm. Usually a more wide lens is recommended, or a really long to enjoy the bird, but as it turned out was the 135mm a really good match of the day.
