SL with R 180mm

Currently I see no reason to call this a temporary solution. I have the impression the single adapter does not offer more, so why buy it additionally. For lenses up to 350 mm (maybe even 500mm) I see no difference. I rather buy batteries with the money saved.

 

 

Using stacked FD-to-M and M-to-SL adapters I get shaded corners with a Canon FD 500mm L lens.  Corner shading is a known problem with Leica's 400mm and especially 560mm f/5.6 and f/6.8 lenses when the lens has an M mount, not so when these lenses are equipped with the R mount.  The M mount's small diameter is the problem.

I wonder about the stress to the mount with multiple stacked adapters. Sounds too Rube Goldberg-ian.

There would be almost no additional stress on the mount. Stacked adapters will be a touch heavier than a single adapter, but because of their close proximity to the camera that slight extra weight has very little leverage and so I doubt that the stacked adapters place any more stress on the mount than, say, the addition of a UV filter at the end of a long lens. Likely greater torque from that because of the distance from the mount.

 

A bigger concern should probably be whether the machining is sufficiently accurate to keep the optical axis perpendicular to the film plane. Based purely on my one anecdotal experience of one M-T adapter and one R -M adapter, no problems at all. It may not be elegant, but it's very practical.

Hello Doug,

 

thanks for putting it straight, but we knew already that the 400 and 560 had difficulties. But I mentioned that all my lenses are 350 or smaller (the 280 plus extenders is no problem), so I have no problem at all with the stacked adapters. And so will the majority of other users, as there are probably not many using the old 400 or 560 Telyts. The remaining question for me is the MR-Telyt-R 500 mirror lens - has anybody tried it with the stacked adapters ? And the 800mm to be very precise, but I have never met anybody who has ever seen this lens outside of a museum.

The 400 and 560 are now relatively cheap to buy, but I have no plan of doing so, because of their (sorry) inferior quality outside the central image. OK. I agree, with the suitable object (e.g. a bird in the center) this could maybe even be turned into an advantage. But I could also imagine using these Telyts in Hasselblad style, with a square format (or also 4:3 if you prefer). That would probably remove or diminish both problems (missing quality of lens near corners and too narrow diameter of the M bayonet.) At least theoretically.

 

To sum up: The Leica adapter stack works flawlessly for almost all R-lenses, apart from one or two exceptions that can also be handled.

Would you agree ?

Another point, just a tiny detail. If you are using both R- and M- lenses (and no SL lenses, which is the case for me), then you never have to remove the M-adapter from the camera. Just exchange the M-lens against the R-lens with R to M adapter. Psychologically I find this somewhat "cleaner".

Not important, but a nice detail (maybe a bit like Mr. Monk   ).

I know that Dunk (dkCambridgeshire) has the Telyt 800 mm. and a SL, so we could ask him to try the stacked adapters.

 

I have the MR-Telyt 500 mm. but no SL yet.

 

I have used the lens and adapters with the Leica T. The T is cropped, so I have no experience with the noticed problems of vignetting you get because of the M-mount diameter.

 

I don't think it is that important to have correction profiles for this lens or to use specifically the Leica T-M-R adapters. 

Because of the nature of the Mirrorlens and FL there is actually no CA and hardly any critical distortion to notice, So the need for a correction-profile is questionable, but the lens details and FL in the DNG-files would be nice.

The connection of the adapters to this lens is always basic, because there isn't an aperture-dial on the lens anyway. The Novoflex T-R adapter does work well for this lens, with the wide T-mount, as the new L-R adapter will have. The Novoflex does well on my Leica T. It only should be possible to use the profiles with it.

 

Then I have also the Minolta Rokkor 800 mm Mirror, with the original Leicaflex R-mount, as requested by Leica before the Telyt 800 mm. was produced,  It has the same quirky specifications as the MR-Telyt 500 mm. But if Leica will/ has to produce a complete list of R-lenses in the SL, they should include this profile also, if only just for me.......

I just checked the list of profiles.  The SL is ready and waiting for two distinct models of 800 mm R lenses.

Scott,

 

You mean there is a listing/profile for my Minolta Rokkor 800 mm. Mirror already? 

This would be a incredible service from Leica, to go back this far in the support of their R-lenses.

 

If so I feel obliged to buy the SL straight away!!

 

But realistically, according to Wiki,  I think there are two versions of the "normal" Telyt 800 mm lenses, the Telyt-S 800 mm./f6.3 and the most recent APO-module version Telyt-R 800 mm./f5.6.

 

So Leica still has to add a third one!!!

..or you can get a single Novoflex R-to-SL adapter:

James,

 

if I use the Novoflex and put on the R 180mm lens. How do I use the SL?

Focus is manual so I put the SL on manual focusing. How do I set the shutter speed and aperture?

Can You please advise me be cause I live in Istanbul and will buy the lens in Holland half april. 

 

Thanks, Gerjan van Asch

All adapted R lenses are used the same way, whether you use the Leica adapters or the Novoflex: 

 

- the SL is automatically in MF mode

- choose Manual or Aperture priority exposure mode, they're the only choices

- focus with the lens

- set aperture with the lens

- in M mode, choose shutter speed with the top dial (same as with any other lens)

- use the BL or toggle button to magnify for focus assistance when required (other toggle button customizations are overridden and not applicable)

 

All other controls work as always. Obviously, none of the AF or IS functions operate. 

 

With the Leica adapters, the one additional step is to set the lens code for the R lens. That nets more information for the camera to work with, the SL populates the EXIF data and generally can provide a more accurate aperture value in the EXIF. The lens codes also let the SL perform some image correction on a per-lens basis. 

[G. van Asch]

Thanks very much for this direct and clear answer! Makes it much easier for me, I'll buy the R180 and the novoflex.

I own a 180/3.4 Apr R lens, and this was one of the main reasons for buying an SL.

I was occasionally using this lens on my M240 with viewer, but didn't find it easy.

Much easier to use and focus on the SL, and the results shooting wide open can only

be described as outstanding. I doubt I will buy an SL auto-focus lens (far too bulky for me - but this

is a personal choice) - the results using my M lenses and the 180 Apo R far exceeded my

expectations.  If you own an SL, and you need a telephoto lens, this is IT.

As I am only using M and R lenses, the T to M  adaptor remains on the camera permanently,

and this combination works fine.

 

 

[G. van Asch]

I am getting the Apo 180/3.4 R are you using the lens for tele or also for closer by?

Can you send some pictures please,

Gerjan

Hi Gerjan

I use the lens for both.

The limit of 500k file size on the forum means that any file I upload won't really justify the true performance of the lens.

All I can say is " it's good"

Thanks I'buy the lens soon.

From personal experience I'm more concerned about the additional joint where fat fingers can accidentally disconnect lens from camera.

Been there done that (accidentally disconnecting camera). I had Nex6 attached to 400telyt with single adapter. Fortunately I had shoulder straps (home made) connected to lens and nothing hit the ground. Now I am always conscious of it.

[G. van Asch]

For the Apo 180/3.4-r it is possible to use a Leica extender 2X-R. I have been looking for a second hand extender. There are two types; extender 2X-R or Apo 2X-R.

There is a large price difference the Apo 600 euro against the 2X-R for about 150 euro. I have been reading on the forum about the difference. 

Is the 2X-R useable on the SL or do I have to save for the Apo 2X-R?

What image quality do you expect?

[G. van Asch]

I live in Istanbul at the Bosporus. The Apo 180 will be mainly used as telelens. The SL is full frame so it will give me enough pixels I think.

I am only using my camera's SL/M8/M6TTL for a hobby so I'm not going to make large prints.

The Leica extender 2X or the expensive Apo extender are the most for ships passing.

The image quality should be Leica like seeing them om my 27 inch Apple screen.

Tanks for your answer,

Gerjan

Hallo,

Look here: Leica L-Mount

[ramarren]

I picked up a 2x-Extender R to use with the 180/4, 180/2.8 v1, and 250/4 v1. It may not be as fine a performer as the APO model, but for my rather casual and infrequent use it does a good job for those odd moments when I need an extremely long lens. 

 

I posted this photo of a toy bear the other day ...

 

 

That was made with the Elmar-R 180mm f/4 fitted with 2x-Extender R, camera on a tripod at about 11-15' (3.5m). I thought the lens did a very reasonable job of it. Looking at the photo carefully in high magnification, I found this reflected in the bear's nose:

 

 

I think that's some pretty good resolution. Of course, it says nothing about flare or bokeh, and little about the rendering of a distant scene. But I haven't had any serious problems using it so far.
