Rm3d factum

[Alkibiades]

It’s a conceptual thing, but It’s about what’s in between me and the subject.
Thanks for testing.
On a Lecia M lens it takes a second. But maybe I can get a Factum for 700€ which is a good price.

This would be indeed very very good price! for that price I would buy it immediately
as a back up to my Rm3.

@Alkibiades:
In you thread (https://www.getdpi.com/forum/index....ron-s-35-mm-apo-sironar-hr.69396/#post-827866) you moved the 33x44 sensor to 15mm on the HR 35mm - right? I’ asking because there is only 11mm on the official lists.

Second question: The focus ring of the Arca-Swiss seems like a left over from the time bevore live view. Or would you still prefer this solution over the classic focus ring?

I read you are selling a lot of stuff. If you are selling a HR 35mm please pm me.
Where are you based?

Thanks.

Yes a very good price, but the money is in the lenses and the back.

Most all of us in tech cameras have wide levels of experience, and I’ll guess most started with one tech camera and then moved to another. They are very hard to assess remotely, have to see them and try in person.

I know about the 15mm vs the 30mm and vs the 20mm of the Cambo WTC.
But I checked files made with the Schneider 35mm XL with 15mm shift and it wasn’t really good in my eyes.
Then I saw the 15mm shifted files from the Rodenstock 35mm HR - very good!

The 40mm Rodenstock needs around 20mm shift to get a 28mm full frame view.
So The Cambo would be needed, 20mm shift and cheap but with expensive lenses. And I think the 35mm with less shift is better than the 40mm with more shift.

I never used technical cameras. I have a Leica M with a 28mm PC lens which allows me 10mm shift.

What I don’t know is the workflow of focusing. Arca has a focus ring or the lens has one?
With the Hasselblad CFVii50c I don’t need the cobal0 version - right?
The Factum has now geared shift - how does this work?
How does the tilt work?

A lot of questions...
Thanks

I suppose Factum shift is not geared. Sharing the same front with RM3Di, focusing and tilt, but separate "fac unit" back side, and the shift does not look like geared.

I don't have one of these but when you posted your question I did a little digging because I'm curious! On a Luminous Landscape review I read that it's 1,800 degrees of rotation (which amounts to 5 turns).

I understand why this would be a concern. Sometimes I'm shooting at infinity, and some times I'm shooting at minimum focus distance for my setup. If you're switching between these distances frequently, it becomes tiresome (but perhaps worth it relative to the other benefits?)

the full 5 turns is not for wider lenses; they reach their specified minimum focus distance within 1-2 turns. You can of course continue to focus it closer if you wish, just like a view camera, but it will be outside of the lens’s optimized range.

I think €700 would be a great but possibly unrealistic price to find one, especially with the “TUM” module (the removable board with the focusing helicoid and lens mount).
I have both RM3Di and Factum and they are both great cameras, but I am considering selling my Factum.
I purchased the Factum to have a small, compact alternative to the RM3Di and perhaps even use it handheld like an Alpa TC or Phase XT, but in practice it is equally useable handheld as the RM3Di is, and I find myself missing having both shift and rise at the same time more often than not.
If I get time this week I should be able to shoot a quick video of focusing my Rodenstock 32 from infinity to close focus to give you an idea.

You are correct; the Factum is not geared, which is actually quite fast if you are stitching.

Would be great!
Please pm me if you decide to sell. Thanks

I shot some videos of going from infinity to close focus (2 feet) and back to infinity on my 32 HR, 43 XL, and 60 XL. Each rotation that my hands do is ~180 degrees (less in the 32 due to its size stopping me from the same range of motion). Reaching close focus distance is approximately 320 degrees for the 32, 560 degrees for the 43, and a laborious 1150 degrees for the 60.

I imagine the 35 would be just a bit more rotation Than the 32 but I’m not sure.
Please PM me if you would like a link to the video. (usm I will send you a link).

Although going from infinity to close focus requires more turns than other systems I have never found this to be a bother... I usually will be within the same range for a shoot and almost never shoot at minimum focus distance. Usually hyperfocal or medium range, which does not require much turning. I do love the precision that the focus system affords.

 

[usm]

Thanks you med! Looks ok for me to turn it...

 

[Vilpo]

Gotta thank the lord the shift was not geared. Sorry I just could not help myself.

Hi!
Here I have some images of the Factum I got a offer. Looks ok for me but maybe some one who knows the camera can look at them. It is a used one, what can be wrong with it?

On some images of other Factum cameras there is connection port on the front of the camera. Just on the opposite of the Arca Logo.
On this Factum this port is missing. Also there is a black textile on the inside where the lens will be attached. Is there Adapter for Digiback attached on this camera?

Another question is: For Portrait I have to use l-bracket- right? Or can I rotate the Back Adapter?

It is difficult to communicate with the seller.

Thanks for helping.

 

[usm]

also the l-bracket are different (black or silver) from time to time?!

 

[Paul2660]

You can easily rotate the back adapter. The feature that the Arca cameras all have is one single release. so you can use one hand to finger the release and hold the back with the other hand. Takes 1/2. Sec to do it. Faster then using the L bracket.

It looks legit, the communication port for e-modules is visible and appears to be one of the 2 existing versons.
There’s no db plate on these pictures, you’ll have to get one. The only extra accessory is the compendium holder.
The l-plate was either silver or black, I think it changed to black quite recently.

 

[Vilpo]

For the easiest switching between landscape and portrait, you can always get a Rotamount

 

[Paul2660]

Rotamount adds a ring to account for its depth. Unless you use it all the time I would just use the simple method of releasing the back and rotating it with your free hand.

[Vilpo]

I supposed it is designed to be used all the time. Preventing you dropping the back, and also reducing a bit of dust exposure when switching between portrait and landscape.

 

[Paul2660]

It’s one way for sure. I just prefer the use of the back release and a quick switch of orientation. I like the Arca back mount design from the start compared to Cambo which has 2 release points

I also had the issue of the focus ring backwards. My mistake. You remove a ring if you want to use the rotomount.

I've had the RM3di and Factum for many years. Having both offer the most fleibility. My go to hiking/packing will always be the Factum. I use mine with an Arca rotating back, and skip the twin L bracket which I find is marginal with a heavy lens like the Rode32 Hr.

If you have an Rm3di, all you need is the Factum frame and you can switch the front and back. Its super rare when I might need to stitch both vertically and horizontally in the same capture so the limitations of the Factum are not really a problem for my style. I've also mostly gone away from stiching and moved to a Arca Nodal set up which I personally find far more effective and versatile....then you have unlimited wide capture and PS does a fabulous job of joining everything.
