This is a 6 element enlarger lens from Rodenstock. The non APO version. Very sharp close up as intended. But focus at long distance produce some glow at 2.8. Stopping takes care of that. Usable as a general purpose lens. An odd feature is a switch that let you almost disengage the click stops. The aperture ring can also be lifted and turned to limit the aperture like, almost like a preset lens. For the price of 20 EUR it was a good buy.
Optical construction found on this page: http://www.prograf.ru/rodenstock/enlarging_en.html
Camera: Sony a7.

Yes Klaus, quite correct; the moire is caused by the sensor. My point was that the lens is so sharp that it "permits" the moire (a less sharp lens "hides" the sensor's lack of an AA filter by not presenting it with fine enough details).
The moire is, in this case, something positive in that it demonstrates the lens sharpness. _________________ Sony A7R and wildly varying flora of lenses |

I got one of these m42-nex helicoid adapters. And a m39-m42 adapter.

I use a simple M42 to Sony E mount helicoid adapter (with a M39-M42 ring screwed on to the M39 threads of the lens). The lens seems to have a flange focal distance similar to that of normal M42 lenses, which means I reach infinity focus at the helicoid's shortest setting (or just before that, but not by much). As a sidenote; other enlarger lenses (such as the El-Nikkor 50/2.8N) have a shorter FFD and require shorter helicoids, so all 50 mm enlargers don't behave the same.
Here's a picture of my lens+adapter/helicoid:

Is it right to say that among many enlarger lenses used for outdoor shooting, Rodagons seem to skip that specific surgical "plateness" of the image? They seem to render closest to "normal" double Gauss, bokeh included, but with an added value of excellent sharpness and saturation all over the field.
Did some of you make a comparison of enlarger lenses you dispose shooting the same outdoor scene? |

I don't know what plateness is. But I have a few more enlarger lenses. Another one that is good is the EL Nikkor 50mm f/2.8 N. The only bad thing is that the aperture can't be fully opened. I want to modify one to do that but it's such a silly idea...
There is a big test on flickr. I'll see if I can find it. I'll may be able to do such a test myself. |

Biotafton,
Thank you for sharing your photos and technique. I am looking forward to trying this as well. I am especially interested in focusing to infinity on a Lumix 4/3 body.
Helicoid adapters have different ranges of extension. What is the minimum distance of extension that allows yours have to achieve focus at infinity?
Thank you, J |

It was Matt's crazy lens adventure that made the test.

I can't find the adapters now but it's either a 12-17mm or 17-31mm. Also a m42-Sony e-mount 1mm thin adapter and a m42-m39 adapter for the lens.
I don't know if there is a similar thin adapter for m4/3. |

to reach infinity Use thinnest helicoid adapter you can get. I used mine from yeenon + m38-m4/3 adapter, if it's over infinity, you can add thinest extension tube
here's the I use for elmar 50/3,5 enlarger lens, should be same with rodagon

Blotafton, thank you for the link to the flickr comparison. It gives curious results. Aside a couple of "low scale" lenses, I do not see a shoking difference.
Well, in part it's the question of the f8 aperture. Like with other lenses, enlarger ones should also tend to similar results with closed diaphragms.
That could aslo be an effect of mid-far distance that does not show so much of difference, especially in bokeh department. Even though, looking in the right low corner where some grass is taken with front bokeh more difference is seen, in termes of CA and colour saturation. Schneiders and Fujis have more punchy front bokeh. While for example the highly praised Komura gives much of CA in this wone while rendering perfectly sharp and punchy in focus.
If you have a curiosity and opportunity to test some of your lenses in a series, that will be really interesting, as you seem to have a nicely attentive eye to some especially important, IQ related details.
Jamaeolus, congratulations for such a beautiful shot. I assume the way the lens' crispness adds to its esthetic icy red knock-out. Have the same great experience in the winter coming! |

I have several APO enlarger lenses. Schneider APO Componon HM: The 40 f2.8, 45mm f4 60mm f4, and a barrel lens 90mm f4.5 and the rodenstock above. I also have EL-Nikkor which I have heard are apo corrected though I can't say for certain. I have the 63mm f4, 50mm 2.8. probably others I can't think of right now. I have a bunch of other enlarger lenses, Schneider componon, and componon S Fuji, Hoya, Freidrich, Elgeet, Minolta, Tomioka, Schacht, vivitar, beslar some other rodenstocks and a few weird ones as well. I am planning to sell a bunch of lenses to target one of the legendary prinitng nikkors. But right now I have to sell a bunch of stuff to get a new tablet. I lost my samsung 9 inch (fell off top of car I think, kinda stupid of me) that I had had for several years. I want to get the new 12.4. Even on the old tablet the ARW files looked way better than the JPG's I see on my run of the mill Dell and Acer monitors at home or work PC's. _________________ photos are moments frozen in time |
