You're right carnagex. I'm using totally manual lenses....my answer to Kristian was not On Topic. Sorry.

This seller on ebay has good feedback, and sells tubes

I ordered a set and have not received them yet, so can't vouch for quality of build.

 

best,

Sorry Jay, the comment about the ektamatic SC is confusing. That's the paper neg material....and has nothing to do with enlarging, other than it is single weight. DUH!

Jay.....I had always heard you needed to contact print paper negs, but not knowing any better I put them in my 4x5 enlarger, and they enlarged fine. I wanted the paper texture too. I've enlarged my 4x5 paper negs to 16x20's with no problem. At f16 on the enlarger lense, it's looking like many of the images were printed at 4.5minutes exposure (onto forte variable contrast warm tone paper).Depends on the filtering of course and the neg's contrast. Again, that's with single weight paper (Ektamatic SC), that has built in developer.

 

thank you for your comments about my work.

I've used single weight, variable contrast paper in 4x5 (Linhof), and 4x5 pinhole cameras. If you use a #1, or so, contrast reducing filter in front of the lens it will help with contrast control. Also, it is very interesting to scan the paper neg using a scanner such as some of the epsons, using the transparency adapter, instead of as a flatbed scan. Then you get the nice innate texture of the paper also, besides the image you've made. You can also use charcoal pencils to draw on the paper side to create better highlights in the positive where needed. Course you need to use a paper that has no company logo on the back.

Thanks Dan for sharing your wisdom on this lens. I think I'll pass on trying this lense on my 5x7.

Hello,

Does anyone know if this lense will cover 5x7?

 

thank you,

Ken

Hello. I have an Epson 4870, and have been scanning Polaroid 55 negs as follows: I place a wide plastic ruler along the side of the flatbed glass, wide enough that it will get into the 6x9" transparency window. I place the neg base side down against the glass (I've had no problems with newton rings so far). Make sure the neg is down from the top of the flatbed glass to allow for the sensing window, like in the epson neg carriers. Close the lid and scan. The ruler causes the neg to be parallel in the scan, so there is little rotation correction needed. I have no problems with sharpness.<div></div>
