Contax Zeiss Distagon 21mm f2.8 Facts & Servicing (CLA)
The Carl Zeiss Distagon 21mm f2.8 C/Y mount lens, is a legendary lens, perhaps the most sought after Contax lens. With its value already very high and steadily rising, and less good copies being available, servicing these decades old lenses to survive modern use has been increasingly important.
I briefly introduce the lens and talk about some facts around this lens, its history and performance. Watch me as I take apart this beautiful lens with love and care, which has a stiff focus problem, haze under the front group, and a bent mount. I give it an overhaul, cleaning all its parts, correcting the bent mount, lubricating the focusing mechanism, cleaning the optics, and assembling the lens back while adjusting it for optimal performance. This lens also has a slight separation on one of its doublet, a common issue with the Contax 21mm f2.8 lenses, but since it doesn't affect performance in its current state, its owner followed my recommendation to not deal with it for the time being.

    So great, to see one of these stunners doing great again. I am sure, i'd get very nervous seeing it disassembled into pieces, because i can't service it on my own. I am uber careful with all of my lenses, even when using them, shooting photographs. I do think, the small blank metal edges need to be recolored black again, and this lens also deserves the original Contax lens cap.

  • @marcp.1752
    @marcp.1752 7 місяців тому

    I own the same, 35/1.4 Contax Distagon. It's pretty clear, that the "Ninja stars" bokeh of the AE version is somewhat worse than the MM (=MultiMode) version. Also the MM does have not only the green smallest aperture, but also newer T* multicoatings. My 35/1.4 seems somehow a kind of hybrid, into the AE - MM transition phase. It's AE from it's barrel, but the rear lens mount clearly shows a MM C/Y bajonet (silver, instead of the all black AE mount) I got a decent deal from a friend of mine - because the Distagon was NOS, hence mean still *is* NOS, because i left it inside the box. I hardly wanted this lens since 89...i do own it now for some months, but haven't used it. Paperbox, zeiss quality control paper certificate, original plastic foil, and the matching leather pouch besides the styropor is all original.

      another question, ive noticed that the floating group doesnt actually rotate, but just follow the movement of the barrel that is connected to the mount. if you place the lens in the camera and rotate the focus ring instead you will notice that the zeiss name wont rotate (the one that rotates is the contax 18mm f4)

    Hello, great job and very informative video. I am a huge fan of Contax Zeiss lenses and agree with everything you said. What I want is modding them into my video kit and putting the Leitax Canon mount on top of the CY mount. For this I have to remove the screws and found out that especially AEG version have very stubborn screws and are actually glued. After many readings and watching videos suggestion is applying heat on the screw, even Simmod lenses do it this way. But as you said we always need proper tools and how to use them, no one mentions what temperature should be used. I have a heat gun with a range of 100 to 500C and I do not want to damage the lens but also not to strip the screw. Do you have and advice? It would much appreciated.

Really enjoyed the personal story about the lense you shared. Supply chain and shipping problems have made this knowledge of how to repair and service what you’ve got or can find essential. Could you do a video talking about the tools you use and how to choose the right tools when working with a lense. I know nothing in this area, but really want to know now. Had no idea this was possible. Nice inclusion of a few seconds of Musky Fire!

    Love this and your other servicing video! Excited for more! I know you mentioned about showing the floating group calibration in another video, but was just wondering how you calibrate infinity without a collimator. Also, do you check to see if the focus distances line up or are the distance marks on these lenses more for reference rather than being perfectly accurate? Thanks!

    • @AreiaMedia
      @AreiaMedia 2 роки тому

      Thank you Ben. At the infinity mark the lens should be able to go just a tiny bit over infinity, not be exactly on infinity. This guarantees the infinity is at the middle of the DOF and thus the sharpest possible and allows allows for mount variance. It's how all modern lenses are calibrated too. Infinity calibration is pretty simple without any special equipment. Your already calibrated lenses are a good indication of how it should be and how the lens should behave. You can do it simply by pointing your camera and lens at a very far object, the stars being the best possible of course. You can use the camera's zoom features or take photos on a tripod, while adjusting the lens. If you do it a few times, it will be something so simple and obvious.

    18:34 what is the normal distance at minimum focus and at infinity? I got the floating element out and didn't do any markings... The usual thing would be to make a marking on the side on the floating group and the lens barrel just where the helicoid comes off, but I didn't... Thanks!

    • @AreiaMedia
      @AreiaMedia 2 роки тому

      You will have to put it at a rough position and tighten the screws on the floating element ring. Mine was 17mm when at infant as I show in the video. Then go to a chart with a camera on a tripod. First focus the lens, then unscrew the three screws slightly. Then zoom in the corners 10x and turn the floaring group till you get the sharpest image. Repeat for the other corners. You might have to refocus the lens at some point and do it all over again if your floating element was way off. When you get the best performance possible, tighten the 3 screws and you are all set. It's much better to so this on a full frame high MP camera with liveview and zoom in capabilities.

      Either the connection between the iris ring and the iris mechanism or the blades are stuck by oil? Put the ring at f16 and try to control the iris with the lever on the back of the mount to see if the iris works alright first.

      @@AreiaMedia Hi I manage to find the issue. The bronze circlip needs to remove and turn the aperture back to position to match the guiding groove. Thank you for your reply.

    Привет. Сделай пожалуйста видео по разборке 28мм 2.8. Ещё вопрос, какую белую краску используешь для цифр?

      Hi. I will make one for the 28/2.8 soon :) I'm using enamel paint for models.

    Hi, very interesting Contax Zeiss videos. I have the 28mm f/2 and it has very stiff focus. I’ve tried to have it serviced here in Iceland where I live without much success. Is there any way of contacting you directly regarding servicing my copy?

    Thanks for this very well-presented instruction video. My copy works perfectly using a helicoid adapter on my mirrorless digital camera. However, it does not focus to infinity on my Contax C/Y-mount cameras nor on my fixed adapter. Is there any simple way to make that +/- millimeter adjustment easily? I already have removed the rubber grip.

    • @AreiaMedia

      Hello Steve. Yes, you have to slightly unscrew each of the screws around the focus ring, till the focus ring becomes light and is not moving the lens helicoid with it. Do not unscrew the two screws on the top. Then you can put the lens on your camera and readjust the focus ring while aiming at infinity. Tighten a couple of screws and turn the ring. Repeat till you are satisfied, the finally tighten all the screws. Do mind, if you unscrew the screws too much the inner gold coupling ring (which you see i am adjusting using a toothpick) could get dislocated and a full dissasembly will be required to put tighten the focus ring correctly. Also, you have to take very small steps st adjusting infinity (relaxing, turning and retightening the focus ring) otherwise the helicoid could get decoupled. So proceed with a lot of caution.

      @@AreiaMedia Thank you again for the clear instructions. It was scary a couple of days, as I had a very difficult time (as you warned) getting the internal ring to sit firmly and to grab it to turn to infinity. I felt I might have totally ruined the expensive lens. Finally I gained infinity focus on my C/Y cameras and very slightly beyond on my E-mount adapters. However, now the mirrors hang up on both my Contax RTS II and Contax 139 Quartz. Strangely, the mirrors work fine on my Yashica C/Y cameras. And, my only other Zeiss lenses--Distagon 28mm/2.8 AEJ--has exactly the same problem. I probably should just be happy the Zeiss lenses work find on my E-mount adapters. 🤔Thanks again!
