Rip,

 

Yes, I see those appear on ebay regularly and get tempted. But I then come to may senses and think "how am I going to focus". I guess they are good for infinity shots and very far objects. But must be difficult to use for general use. Anyone have experience with these? Or, is the main attraction a display shelf?

Rip,

I use these tubes on my 3 SLR (R8,R4S et SL) and it works well :)

It is less bulky than Viso and bellows and can take in the countryside in a backpack and on his bike, very convenient .....

 

Question off topic of this thread:

Are there any extensions tube like this one but in bayonet that will fit on the M9 or M8 ?

Thanks

Henry

This tube will fit any M mount camera, of course including the M9. It is meant to be used instead of the Visoflex I and the OUBIO adapter, with the 200mm Telyt, 280mm Telyt (versions I and II) and the 400mm Telyt (version I and II only).

 

The only way to use this combination on a Leica SLR is via a 22228 adapter or its Chinese or Japanese equivalent.

 

Best,

I put a Camera Quest 39mm to M bayonet adapter on it…. I use the Camera Quest

adapters because they are always accurate unlike many of the cheaper eBay offers.

I attached the 200mm Telyt to the other side.

I focused the lens to infinity and used the rangefinder focus spot to center the lens on

a mountain quite far away.

This is what I got. Picture 2 is a real tight crop.

I guess the flash mount is used for a 200mm external rangefinder for focusing the lens.

Yes, easy to use at infinity.

 

I don't think we are all talking about the same thing here. What Rip has posted is an adapter that was intended to replace the Viso I system where the user guesses the focus. Works great at infinity. The adapter should be 62.5mm thick. There is also a version with an M mount at the camera end (then 63.5mm thick). Please check the Wiki on this site for pics, names and more info. They are listed there.

 

Henry is probably talking about other, similar spacer rings with LTM at both ends. I've seen these in 7.5mm, 15mm, 30mm, 45mm, 60mm lengths and I have no doubt there are others. Oh yes, I've also seen 21.5mm thick LTM spacers which would be the replacement of a OUBIO if a LTM-M adapter is added.

 

Again, I ask: How functional is it if you are doing something more complicated than focus at infinity?

I did not get a finder with it and I have no desire to have one…. but the tube and lens I

now see do work ok on the M-9 body ….. it may just allow my 200mm to work on this

goofy little Ricoh GXR when the Leica lens module is available….. next month I’m told.

The GXR takes nice pictures and I have been having fun with it. It seems to do very well

at high ISO…. interesting gizmo.

I picked up a TZFOO with a SFTOO that has an accessory shoe (non-Leitz) mounted on its top. Obviously intended for the accessory rangefinder. Problem mostly solved, the rangefinder goes out to 300 feet, while the 20cm Telyt has markings out to 1000 feet!

Henry,

 

After having read your PM I realized that I was spreading missinformation and I apologize....:o

 

The TZFOO cannot be used on a Leica SLR - no adapter will help. Infinity focus would simply be not possible. If you already have the lenses mentioned in my post, you will need OUBIO and 14127 (or 14167) adapters to mount them on an R or Leicaflex body. Both appear on fleaBay quite often.

 

Ashes falling from my head.....

The non-standard accessory shoe is intended for a viewfinder; I'm pretty sure that Leitz never marketed a rangefinder to use with long lenses.

 

For focusing, you could use a long tape measure (I'm serious: for some applications, e.g. many athletic events, you can measure the various distances in advance and set them on the focusing scale as required) or rely on estimation and DOF.

 

(The very long base of the Contax rangefinder allowed Zeiss to sell coupled lenses up to 180mm, though I'm not sure how practical this was with the 180/2.8.)
