The wide angle lens that I got for 8x10 prints is a Spiratone, 35mm, f/3.5
This explains a lot

I'm trying to think of a modern equivalent of Spiratone - how about Walmart house brand, but sold only through mail order?

Ha ha.
Thing is, I looked up Spiratone before I bought it. I knew it was a "generic" brand and I read that it'd sometimes be sold under various names like Durst and it might come in by default in a budget enlarger. I reasoned "Ok, so it's a budget lens, but if gets rebranded then it can't be *bad*. It's like buying Walmart brand products."
What can I say? I bought it 3 weeks ago. I was young and naive back then.
I don't feel too bad over the $30 lost. I was reluctant to invest into an expensive lens not knowing if it would actually enlarge half-frame to 8x10.
At this point I can confirm that the projected image appears to fill an 8x10 but I have not yet made any actual prints. I have 8x10 paper but I haven't used it yet. If I was looking to upgrade my 35 mm lens, would you think that this Schneider 35mm f/4 Componon for $125 USD on eBay would be a good purchase? Or should I wait until I'm ready to spend more on something else?
Make yourself a test negative, as follows. Take a piece of black, developed film, such as a film leader. Lightly scratch a grid of fine lines on the emulsion side, using a very sharp point, such as the tip of a knife. It doesn’t have to be neat. Put this in your enlarger (emulsion down, of course), open the aperture fully, and study the projected pattern (with all the other lights off). The back of a scrap print makes a better focusing surface than the shiny enlarger easel. You’ll be able to see clearly where any unsharpness lies. You don’t need an expensive grain focusser for this.
Remember to stop down the enlarger lens from wide open when you're done composing and focusing and are ready to start making test strips and print. With the Rodenstock, the sharpest setting would probably be around f/4 to f/5.6 (assuming you don't need depth of field to compensate for other issues).
If you do go down the path of checking the alignment of your enlarger, The Naked Photographer has a pretty good series on en larger alignment. But he doesn't have your spesific enlarger, unfortunately.
You will then be looking at the back of the film. The emulsion side is generally dull in appearance.I'm going to ask a really dumb question: Which side is the emulsion side? Like... if I am holding the film and I can read the text "Kentmere 100" correctly, am I staring at the emulsion or the back?
Because you should be placing your negatives in the enlarger emulsion side down. Otherwise you would be projecting your image through the back of the film, which will degrade its sharpness, besides which the image will be flipped L-R.Next dumb question: Why does it matter if I place the film emulsion side down?
If you're going to continue using a 1/2 frame camera, I'd spring for the Componon. They are very good lenses.
As long as you stay with the Spiratone....check out the article in the link i added:
"Corner Sharpness vs. Aperture:
The corner performance of this lens is only so-so at the sharpest aperture of f/4. At higher magnification, f/4 improves enough to not be a problem. If you want improved corner sharpness, f/5.6 is a good compromise."
I have enlarging lenses from 50mm to 210..... all with pristine glass.It's always so difficult to know what I'm buying when I buy used. The description of the lens I linked to says
"There is internal dust, haze, and fungus in the glass. This item has been well loved, having the look only a photographer could admire. The glass will have imperfections which will negatively impact image quality."
But for all I know, all the other 35 mm lenses at this price point could be just as bad or worse and the sellers are less forthcoming about defects, or don't even know to look for them. There are two 35mm f/4 Rodenstocks with no information and not a single image that allows you to actually see the lens, nor claims about the lens condition.
Some sellers clearly have no idea what they're selling. I'm looking at a post that says it's a "35 mm lens, Nikon mount, unknown brand", so of course it is an f = 50 mm El Nikkor. The seller thought that a 35 mm lens is one intended for enlarging 35 mm film.
I don't want to buy a bad 35 mm lens. For that, I can keep using the one I have to learn the ropes. But if the $125 USD Componon is a good improvement over what I have and the seller is just being cautious with their description of haze + fungus, then $125 is a price I am willing to pay to get reasonably sharp corners at 8x10.
Thanks for the link! Ok. Now I know to use it at f/5.6
From the link: "Street Price: About $5 in good used condition."Ok. I wasted $25.

I would not buy an enlarging lens with fungus....especially not for that price.
Igors has a clean El Nikkor 40mm for $95......

Hmm... I can't find it on their eBay store (which appears to be their online online store).
I found this El Nikkor 40mm for $90 with shipping from a different seller. The description says it "saw little use". There's another one here for $106 with shipping that also claims to be well cared-for. I think the second lens looks a bit cleaner, but it's hard to tell.
Quick question: My impression is that the El-Nikkor and Rodenstock are similar quality and my best strategy is to use the 50 mm Rodenstock for 5x7 prints and the new 40 mm for 8x10 so as to keep the enlarger head higher up. Would that be accurate?
With that size of negative, you may want to use the 40mm lens mostly, but save the 50mm lens for even smaller than 5x7 prints.
Leaving the 40 mm lens on all the time is convenient. Can you explain to me why that's a better strategy for my small size negative?
I am looking for information online about which brand is better, and I'm not seeing a lot of definitive answers, which suggests that they are at lest comparable.
Maybe. There are a number of different kinds of Rodenstock lens. In general, you always want a 6 element lens over a 3 or 4 element, it will have better corrections and give a higher quality image.
As far as I know, the recent Nikkors are all 6 element.

I found a PDF of a Nikon EL Nikkor brochure. The 40mm f4 is for 5X-30X where the 50mm 2.8 is for 2X-20X from a standard 24x36mm 35mm negative. Apparently it's for big prints with a standard enlarger column without having to project on a wall etc.
I always imagined that the 40mm was for half frame, I learned something.
30X would be approximately 28x42 inches. You'd need Technical Pan film and some NASA soup for that![]()
It really depends on your light source. My 50mm is 2.8, my 80mm f4, and my 105, 150 Rodagons and 210 Componon are 5.6. The lens i choose depends on the film format and i never have difficulty focusing despite the differing maximum apertures.Most likely it will lead to the enlarger head being at a convenient working height, but not right at the top of the column, where any instability in the enlarger is most likely to reveal itself.
And based on the data quoted above by @mschchem, a 5x7 enlargement is ~ 7X, so within the range it was designed for.
Soon enough you will get a feel for where it is most convenient to have the enlarger head, and if you have a choice between quality alternatives, you can let convenience inform your choice.
An f/2.8 lens does have one advantage over an f/4 lens: at maximum opening, the image is brighter and easy to use for composing and focusing. That isn't as much an issue for B&W as it is colour.
Can I get a copy of that PDF?![]()
