Lens Question: Telyt-R 560 f:6.8

One of mine friends had the opportunity to buy the Telyt-R 560 f:6.8. He should use it on an Olympus body, using a Leica R to 4/3 adapter.

 

The problem is that the focusing system seems quite hard to push forward and backward. In your experiece, which type of maintenance should he perform on the sliding mechanism? Is there any type of oil that can be used to lubrificate the mechanism?

 

Thanks in advance for your answers.

Best regards.

Ciao Paolo, e benvenuto nel forum !!!

 

I suppose your friend DOES know that to move the "trombone-like" focusing tube you have to PUSH the rubber button on it... without pushing it's indeed a bit hard.... ;).

If even with correctly pushing the button it doesn't move smooth... I think is better not to try to lubricate it in do-it-yourself way... the issue could be not only in lubricant, but in some other kind of mechanical interference... better to have the lens revised by a competent lab... in Italy there are some very good and trustable.

 

BTW... 560mm on a 4/3 !!! Funny supertele combo !!! And getting the best part of Telyt's area of coverage (long telyts are not so good at borders - widely cropped away with 4/3 sensor...)

The edge problems are just Curved Field Aberration, invisible when the lens is used for three-dimensional objects. Actually the clarity of these lenses is amazing and the resolution in the centre quite high.

Yes, my friend knows the use of that rubber button :o. I tried by myself to use that "trombone-like" glass on my walkaround camera (Olympus E410) and the focusing mechanism is somewaht hard to move. I mean, you can move it obvoiusly but by the way it's not smooth at all. From the serial number it should be built around first '80s, and it seems to be almost never used. The aperture ring is ok, very precise, the only problem is the hardening of the focus action.

Can you suggest me some laboratories for the maintenance?

 

In any case, put on a tripod and with the E-410 behind it, it's able to deliver very impressive images (with an equivalent focal length of 1120 mm). Maybe the photo seen at 100% are not so defined as those from my APO Telyt-R 280 f:2.8 (the older version, E5.5 series), but colours and contrast seems outstanding to me. And the extra reach is very useful.

Best regards.

In Milano, Benatti or R&C (known as "Rentsch"), and of course in Genova the well known SAMCA... none of them is cheap, but the long Telyts are so excellent lenses (personally, I prefer the 560 in the f 5,6 version, and the 400 in the f6,8 version... matter of taste... :)) that are fully worth a well done job.

...that's the one I have - Telyt-R 560/5.6 - and I'm trying to exchange mount to Nikon mount...I'm posting about it on a separate thread...!

used on a DX size dslr one gets "effectively" a 840mm lens...

This lens has the rods that are used as sliders between the two aluminum lens tubes. They are availible in three diameters, to make the fit and sliding action perfect. You would have to disassemble the tube and mic the diameter of the rods, and see if smaller diameter one are still availible from leica.

Even when properly lubricated this lens is front-heavy and can be difficult to focus smoothly if not balanced correctly. I use the index finger of my left hand to support the forward part of the lens, and the last two fingers of this hand to pull down on the rear of the lens head (on the grip provided for this purpose on the right side of the lens head). It takes some practice but the results are worth it.

Doug,

thanks for your indication.

As soon as I can get my hands on my friend's "gun" I'll try it.

Both me and my friend will never make a photo like yours in all our life, but for sure we will try...;)

By the way, it's a long time that we have "bookmarked" your website. It's wonderful.

My best regards.
