<p>is this my lens but with a screw mount adapter added to make it Rollei SL 66 compatible?<br>

<p>Can anyone find a lens board with a 51mm thread? i'm struggling. As someone eluded to earlier, maybe the extra screw in mount that came with this lens was purely used to trap the lens to the lens board?<br>

Also, do you think with the right adapters and extension tubes i could use it as a fixed focus lens for my canon 5d MII? Do M51 adapters even exist? </p>

 

<p>Cheers Raymond, so i could shoot 5 x 4 on it then. That's decent. Where did you find that info?</p>

<p>oh, by the way, Dan, i've only just seen your post about what N51 means. Thanks, for that! So it's an m51 threaded large format lens eh?</p>

<p>The knurled ring is for the aperture. No distance scale either. It's certainly for large format, i just presume there is a part missing that means i can attach it to a lens board..? Globicas appear to be very rare so i doubt i can ever use this lens as you believe it might be intended Raymond. </p>

<p>My lens seems very similar to this... M53 mount?....<br>

<p>Hmmm, very interesting! So we know that it was made in 1970-1975, but surely it has to be for large format as there is no focusing on the lens barrel? The bayonet part was threaded on and i have removed it! The lens is therefore threaded, but what cameras take such a thread size? It's certainly not m42!</p><div></div>

<p>Hi there,<br /> Recently acquired a Zeiss Tessar 4.5/180. I can't work out what camera's it can be used with? Can anyone identify the lens mount? Is it modified? I thought it was a large format lens but it seems the bayonet style mount isn't likely to be mounted on a lens board... so I'm at a loss!<br />Can anyone shed some light? Take a look at the pictures. (i might also add that the lens is marked'N51'...anyone know what this means?)<br>

Thanks.<br>

<br /> A couple snaps of the lens...<br /> http://s1297.beta.photobucket.com/user/imageurltim/library/<br /> <br />This is the lens we are dealing with...</p>

<p>Thank you, okay I'll try posting there too.</p>

<p>Hello.<br>

Recently acquired this lens and i can't work out what cameras/ lens-boards it is compatible with? Has it been modified? The aperture ring is marked 'N51' what might this mean? Have a look at the pics and see what you can tell me... Thanks.<br>

<p>I have a Mamiya c33 tlr and the viewing lens is bloomed, and i would like to remove it? Is this possible? cheers.</p>

<p>Cheers Dave! I'm already starting to get to grips with the camera now (although i havent tested a film) - but it seems to me the shutter speeds have improved a little bit as i keep winding and shooting...<br>

I knew it was built well but this camera is a true beast - it weighs so much! I cleaned the housing of the camera and it has come up very nicely! The viewing lens is bloomed and i would like to remove this... is that possible and if so, how? And is it hard to remove and clean the viewfinder / how?</p>

<p> </p>

<p>ALSO... should the exposure counter wind when there is no film loaded?? cheers guys!</p>

<p>Thanks Bill and Dave. Very useful advice. It seems you have to wind until the winder locks and then wind backwards slightly to set the shutter speed. Shutter seems to be sticking at speeds of 1/4 and less. Damn. It's a nice lens though, the 80mm from the black series. Any tips on sorting out the shutter speeds or will have to be proffesionally done?...</p>

<p>Hi,<br>

Just bought the C33 but it seems the shutter isn't working? Also, do i need another back for single exposure photography?... I just want to take a set of 6x6 photographs on 120 film....</p>

<p>please help me! Any info would be much appreciated.</p>
