Hi Friends,

I have designed a new monolithic 4x5 Camera like Travelwide, Willtravel....

Monolithic means its made for 130/135 mm lenses only. It has a precision focusing helicoid.

The Idea is to have a riggid 4x5 precision camera, fast setup on location, perfect parallel plane of focus.

The camera is 3d printed with quality PLA+, with 100% infill and 1cm thick cone walls, it weight around 900 Gramms.

Focusing is possible down to below 1m.

I have testet 4 classic 130/135 lens designs so far.

Tell me what you think, friends.

That looks very nice, in fact. Convenient to use, quick to set up; very smart!
Did you also 3D print the helicoid, or was that a ready-made part you could somehow obtain? If so, where did you get it from?
It took a pretty long to print, I imagine. Print quality looks impressive btw.

Thanks for your Feedback,

The Flange, Helicoid, Lensmount and Tripod Mount are ready to use parts, printing takes about 30h. The Groundglas is selfmade.

First of all, I would like to express my respect for your efforts in creating such an attractive piece of equipment through a strict process. It is true that all-in-one equipment is useful for shooting in locations where the ground is not in good condition, the wind is blowing, and jet lag makes it difficult to maintain concentration. I also walked around taking photos everywhere with a Kickstarter-made piece of equipment called "Wanderer" that was designed specifically for 90mm and 65mm lenses. (I used the SA 65mm f8 on it) Of course, I thought this was a great camera, but I realized that the only way to express it was by aperture. I felt like I wanted to swing or tilt it even a little. So I honestly felt that this would be better for special mission equipment.

A word of caution. Never take a PLA printed item out into the July sun, especially black. Lesson learned the hardest way.

As I recall when I did my Will Travel (90mm) I used 3 or 4 walls and 50% infill, which seems to be fine, but a denser construction will do no harm.

It does take some effort to work with the large format, fixed lens, and depth of field limits compared to a camera with movements, but it is more portable and spontaneous.

That's true. I have a friend who uses a variant of this equipment in the woods.

Nice job!! I have that Eurynar lens in a 9 x 12 plate camera. I'll have to try it out with film now that I have a film back (3-D printed) that takes 4 x 5 film for the camera. I've hand held my 9 x 12 Bergheil but not the one with a Eurynar.

HI Friends,

Last month i did a lot design changes to my camera now all "normal lenses" for 4x5 are compatible, full coverage from near to far from 130-150 mm, portrait orientation, fresnel screen, graflok, 6x9 mask, new gg holder......now i am finished and the camera is going on sale. Tell me what you think.

That's nice, but ... The focusing panel appears to be for 2x3 (6x9 is a poor metric approximation). One of your photos shows of the final design with what appears to be a 2x3 roll holder for a 2x3, not a 4x5, camera. If it really is a 2x3 camera, the normal focal length for the format is 100, not 150, mm. Your photos show your camera in portrait orientation. There doesn't appear to be a way, without external bracketry, to put it on a tripod in landscape orientation. It appears to be a fixed lens camera; I suppose that lens cones for different focal lengths are possible.

The original design appears to be for 4x5. Why did you abandon that?

Please tell me why I should replace my relatively inexpensive humble 2x3 Graphics, which have tripod sockets for landscape and portrait orientation and accepts focal lengths from 38 mm to 250 mm without the expense and bulk of lens cones, with a Milo Monolith.

Hi Dan,

I’m a big fan of old 9x12 cm field cameras from the turn of the century to the 1940s. I’ve owned many of them in my collection, some in almost mint condition, while others were completely ruined. These cameras and their lenses are a technical masterpiece of their time. Unfortunately, they are not very usable today due to the limited film selection, the difficulty of loading film, and the fragile holders, which are far inferior to the 4x5 Fidelity holders. However, the lenses are often of exceptional quality and have their own unique charm.

My goal was to continue using these lenses, so I bought a 4x5 Intrepid camera. On my first attempts with the camera, I realized that the setup and adjustment process was so time-consuming that I quickly lost interest. I wanted to have large negatives, the ability to shoot on glass plates, and, of course, to use the lenses I had collected over the years.

I came across the Wanderlust camera and thought it might be the perfect solution. However, it became clear to me that the Wanderlust design couldn’t be modified and adapted to my needs, and the printed helicoid wasn’t quite what I was looking for. That’s when I decided to design something of my own.

I achieved my goal with the following key features:

Portrait Orientation: Almost all 9x12 cameras from the early 1900s were used in portrait mode. Sure, you can buy an L-bracket and use the Milo Monolith in landscape mode, but personally, I shoot about 90% of my images in portrait orientation.

Robustness and Weight: The camera was intentionally designed with thick walls and a 100% filled print. I wanted it to be heavy for stability. Light 4x5 cameras with bellows are unstable when there’s a bit of wind. The Milo Monolith is heavy and offers better resistance to camera shake, reducing the risk of motion blur.

Lens Compatibility: The lenses used on 9x12 cameras typically range from 130mm to 150mm. My goal was to design a conical shape and dimension that would allow me to use as many of these lenses as possible. I succeeded in this – all the lenses in this range from my collection work perfectly, providing full coverage of the 4x5 negative from around 1 meter to infinity. The cone doesn’t change, only the helicoid does. For my Dagor 130mm, I use a 17-30 helicoid, while all other lenses work with a 25-55 helicoid.

Graflok Back: I also integrated a Graflok-style back, allowing me to use Horseman 4x5 backs for 6x9/6x7/6x6 film formats. At the same time, I created several masks to help frame the image perfectly. I enjoy using roll film because, firstly, it gives me a slightly different – and sometimes useful – focal length. A 150mm lens on roll film (6x9) behaves like a 65mm lens on full-frame. Secondly, it allows me to shoot color photographs more affordably. The longer focal length helps me achieve better subject isolation.

The back also features a Fresnel lens, which wasn’t available on cameras back in the day.

Monolithic, Bellows-Free Design: This design makes it possible to set up the camera very quickly, take the shot, and move on. When I’m on a hike with my family, I don’t have the luxury of stopping for 20 minutes to set up a shot. Often, you’re not even allowed to use a tripod, and you have to shoot handheld. With an external viewfinder, this becomes entirely possible.

As you can see, the Milo Monolith is a highly versatile camera/platform that allows you to continue using the great old lenses from traditional field cameras.

This camera will not replace your current 4x5 bellows camera, but it is an excellent complement for certain situations.

Lastly, I’ve had enough of discussions with passersby about my photography. The longer I stay in one place, the greater the chance of someone approaching and engaging in a conversation that I really don’t want to have.
