Came across a link for this on my Facebook feed this morning, and the timing couldn’t be better! I’ve had an old Bausch and Lomb projector lens sitting in my studio for about a year, waiting for me to think of a way to put it on my monorail camera and get a working shutter. But early this week, an old friend contacted me about his dad selling his old camera gear, and I managed to score several great cameras pretty inexpensively, including a speed graphic in good condition for only $50! Now that I have a focal plane shutter to work with, I just have to get this thing mounted so I can start using it for portraits! This video was extremely helpful, thank you so much!

The old Packard pneumatic shutter you described is a great very inexpensive shutter for someone who wants to experiment with barrel lenses!

I have one of those red Buhl projector lenses I use for wet plate. I ended up using pipe clamps on either side of the board to mount it (with rubber bands under the clamps). Since there’s no aperture I found a way to fit a variable ND to it to control the light coming in for lenscap shutter work.

Thanks for the tip Nick! Playing around with Ed's barrel lenses make me want to explore a bit more into projector and aerial lenses.

I think that big Liesegang one is made for a device called episcope which is a type of projector used to project non transparent documents like pictures, pages of books etc. They worked by illuminating the document from above with an incandescent bulb and projecting the reflected image on a screen so obviously a fast lens was needed to get a reasonably bright image even in a dark room. I saw one in use when I was in the elementary school back in the 70:s, a big box with a huge lens like that one. It had platform in the bottom on which the teacher placed the book and used a lever to raise the platform against a glass in the bottom of the projector. Even with that big lens and lights off in the classroom the projected image was quite dim. I even think it might have been made by Liesegang, at least some of the slide projectors they used were.

good and informative video. one correction though: not all brass/petzval lenses are pictorial lenses. pictorial lenses were desgined to offer a pictorial/soft look. there were quite a few lenses in that category (Pinkham&Smith lenses, Eidoscope by Hermagis, Objectif d’Artiste by Puyo & Pulligny, Wollensak Verito and some more..). the portrait petzval on the other hand was designed for exact the oposite, it offered a very sharp center at a quite open aperture (somewhere around F3 - F4 usually). leaving the sharp center, the sharpness decreased quite quickly towards the edges for the image circle though (that was the price for its speed). thats why you might think they are not as overall sharp as more modern lenses. as you can see there are brass lenses that might be pictorial, and some that might be petzval lenses. for more info and a dedicated webshop for antique large format lenses you might visit: www.wetplatedreams.com

in 1979 I bought a used 8x10 camera with a former aerial cameras lens, the 305mm Aero-Ektar. It was soooo sharp but the shutter it was in only went to 1/50th sec so it got traded in.

@@MatMarrash If memory serves it had a Wollensak shutter, big black thing. I believe that it originally was on a K-24 aerial camera. It had Lithium glass and was radio active. When I went to the USAF Photo school at Lowry AFB in 1964 we had to start with a Deardorf 8x10 camera with a Wollensak triple convertible lens. To get wide angle or telephoto you removed the front or read element. Very sharp lens indeed.

But, no hat? I stop the lens down, fix a large square ND8 filter in front with its filter holder and rubber bands, and hey presto! I have shutter times of multiple seconds which extend even further because of reciprocity. By that time, I start and stop the exposure with my hat. I shot a 32 second exposure of a forest bench with myself in it as a see-through ghost, timed it with the smartphone stopwatch. Great fun!

Heidosmat 150mm 2.8 is good and covers 4x5. Also those Liesegang lenses are pretty good. I have 330mm f3.3, wich can used in 8x10.

Not every old barrel lens is soft focus, the centre of a nice Petzval is very sharp indeed. The Packard shutter can be snapped faster, it's how you press that bulb, there's a pin on the shutter which you can pull out to switch mode.

I have 1 lens in barrel, Kodak Commercial Ektar 10" 6.3 on my 5x7 Kodak 33a and for a shutter it's the old lens cap method. :)

Hi Matt interesting show as always.. One comment I would like to make concerning Sinar DB mount lenses. Not all will fit into a normal shutter. I came across a few mainly ‘0’ size eg 150-90mm which had adaptors fitted to the elements so they would only fit the DB mount. These could be nearly impossible to remove so anyone looking to transfer a DB element set please ensure they fit into a shutter before buying. Are you going to make some more outside videos?

Hi Mat! How do you identify the threads of a flange or threads on a brass lens. If you have a screw pitch gauge would that work? And how are the designated? Thanks! Thinking about getting a 14" petzval for my 8x10 D2, but need to know more about flanges.

Hey Dorothy! Before breaking out the measurement tools I always try to find data sheets or old marketing materials if possible. Check to see if Antiquecameras has the data you're looking for: www.antiquecameras.net/petzvallens.html Other than that, I'll use a set of calipers to measure the thread pitch as well and diameter of the threads. If you need a custom flange that doubles as a lensboard (for big lenses) check out Luland on eBay: www.ebay.com/itm/Luland-professional-custom-large-format-camera-lens-board-and-accessories/182867265920?hash=item2a93bd0980:g:SygAAOSw1-hfAwWn

Hey John thanks for the question. It's definitely possible to mount barrel lenses on digital cameras. Mirrorless cameras have made it so much easier to adapt, really the only hard part is finding one that doesn't have a very long focal length and the materials to mount the lens. I know several photographers that have done this with medium format film and mirrorless cameras. Many of which are using Novoflex and Fotodiox adapters for their camera systems.
