I bought this lens with the hopes of using it on my speed graphic.

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...

If the rear elements are seperating, then yes that will effect the image--TO THE EXTENT THAT YOU USE THAT PART OF THE LENS.

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

It is not on the edge.. maybe it really isn't "separation"

where can I forward a pic too? I took a digital last night.

Is this lens worth messing with?? I paid $8 for it..

Dear Fishhead,
This is not a site to peddle your wares---use ebay for that. I am requesting that your previous post be stricken from the site.

While it may not have been the perfect place to load photos of the lens in question,I don't see what the big deal is either.

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

Let me work on getting a separate page for the lens.

I also have a shutter I have questions on.. 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.

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!

Looks like the censor got to "f-o-r s-a-l-e" in the sentence "All are *******." Too bad the filter doesn't work on attachments.

If you would have read the previous post before you wasted your breath once again....

I will move the lens pictures to a different page...

It looks like halations on the coating-- the same effect as a star filter to a degree.
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.

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...
