I will read was is enscribed along the rim of the lens. Bausch & Lomb Opt. Co Rochester, NY USA then has a yellow dot and a purple dot Tessar IC 190mm E.F f/4.5 LF3508 I can see one problem with the lens. It has a rainbow like pattern on the rear element. It was mentioned that the glue was coming loose on the glass... Will this affect photo quality on B&W? (I don't do color) Can I also use this as an enlarging lens? or will the above problem affect photos? thanks I can send pics if I know where to send them too... ________ justin bieber fan |

If the the separation is a few millimeters from the edge, then stopping the lens down will eliminate the problem. |

If the the separation is a few millimeters from the edge, then stopping the lens down will eliminate the problem. At this point test the lens at 4.5 5.6 8 11 & 16 and look at the negs with a loupe. The proof is in the pudding |

But I also don't see the pics of the Tessar lensr. The last series of photos I get to load are the travel pics, the last being of the boats, but nothing more, and with a 56k modem running 48K it took several minutes to get that far |

I will put them on a different page.. the lens was in the middle before the "travel" pics. it shows the bottom view so it is hard to see if it is a lens. ________ Ford Orion history |
| Henry Joined: 09 May 2001 Posts: 1662 | Posted: Tue May 15, 2001 4:09 pm The "big deal" is that with image number 2 the caption reads "All leather is intact, no rips or tears. Tripod mount threads are good!!" Image no. 4 reads "SRT 101 with Mirror Lock-up and DOF preview. EX++". Image no. 5 reads "152mm, 135mm, 127mm in lensboard All are ******* 135 mm comes with camera." If this isn't a blatant sales pitch, there was no Chicago Fire. As I said before, peddle your wares on eBay, NOT on the Helpboard! |

Too bad the filter doesn't work on attachments. _________________ <font size=-1>[ This Message was edited by: Henry on 2001-05-15 09:13 ]</font> |

| Fishhead Joined: 10 May 2001 Posts: 42 | Posted: Tue May 15, 2001 5:06 pm I have the URL for the lens. I am also going to add (maybe tonight) another lens I have questions on. http://gregarpp.iwarp.com/photo2.html these should load faster!! thanks ________ Toyota TF107 history |

It may also be the begining of separartion. I had a 162 Optar that had concentric dark rings in the rear element and a bit of difraction like yours. I never shot it so I can't say what the effect was. I still say you'll get much more accurate information by testing the lens. It may be that it will effect color more than B&W. It may also turn out to be a very good portrait lens. |
| Fishhead Joined: 10 May 2001 Posts: 42 | Posted: Tue May 15, 2001 6:11 pm Is this lens worth the money to buy a new rear element? Is it worthwhile to use it as an enlarging lens for 4X5? I plan on shooting it soon... ________ Edsel |
