....I ask you the same for a bellows for the GFX.
Just poke around by Google search options as for several medium camera format bellows - click to "images" as for output.
And you'll see by pictures which bellows do have more or less potential as a choice.

When doing this (all kinds of searching as e.g. Hasselblad - Zenza Bronica etc.)
it looks like models as for Pentax 6x7 - Mamiya 645 and Contax 645 have the better options.
"Professional" grade finishing, than found from several other medium format offerings.
But always keep in mind, that by the age of these devices, you have less insight in condition and wear.
(And check for adapting for camera and lens options).

https://www.google.com/search?q=Pentax+6x7+bellows - and click to images.

By that search - handy found resources in general - and Pentax 6x7 bellows:

I have found a second hand option in Europe (The Netherlands) as for Pentax 6x7 bellow,
but have my doubts about the condition of the bellows themselves. (Just contact).

As for bellows, also Mamiya 645 options seems to be a good option.

https://www.google.com/search?q=Mamiya+645+bellows - and click to images.

By that search - handy found resources as for Mamiya 645 bellows:

https://www.pentaconsix.com/viewcam.htm

From the same supplier in The Netherlands, but sold:
https://fotohandeldelfshaven.nl/product ... movements/

Just contact, when he get other equipment, to contact you.
The supplier is specialised in vintage gear. So always keen to look around himself for offerings (world wide ?).
And update his stock offerings as a seller.

----------

Very, very nice options as for Contax 645 bellows.
Build with all kind of "technical camera" movements. By that, more expensive.

As for adapting Fuji GFX to Contax 645 (for bellows), even with electronically adapted - working Contax autofocus lenses.
https://www.fringeradapter.com/contax-6 ... jifilm-gfx (German supplier).
https://kipon.com/product/contax645-gfx-af/

Don't know if the Japanese camera supplier is understanding English, and send to Europe to.
But his offering of a Contax bellows - by exchange Yen to Euro ---> 98000 Yen = ~€ 610,-
That Japanese offering is the best. (Even when extra tax & import duties is added).

(And check a private message I send to you).

Sorry for the technical ignorance but why is one system better than the other? Thanks.

I really appreciate your suggestions but I always have to buy within Europe otherwise customs makes me pay a horrendous amount of taxes, other various costs and they generally hold things for weeks and weeks, for no apparent reason (when they don't lose them or send them backwards due to some mistake of theirs). I've been through these sagas and I don't want any more. Thanks again.

Yes, proper organisation of custom services can be different in one or the other European country.
At least, extra VAT should be a fixed percentage that should be given as by information at webpages of the department.
Also the extra customs clearance costs, should be known in advance.

Dutch custom services seems to do well in general. In which country are you living?
(Within the Netherlands products mostly are delivered already, and paying tax etc. is send separately and to be paid afterwards).
I have over 20 years experience from buying abroad, as e.g. by USA - eBay - Japan - Ukraine.

In case of buying from AliExpress, they have already organised their service to such a high automated level.
That VAT / tax of your country already is part when buying of articles. (However always check as per reseller).
The VAT is noted already by the invoice of the product. (So you have already "proof", that you paid VAT already).
No additional fees should be paid. The only "extra" fee is e.g. for fast express delivery that can be added by your own choice.
(E.g. once I ordered a nice tripod by AliExpress, and was delivered in 6-7 days as from order date and shipped from China / Hong-Kong).
But be keen, that shipping of products can have extra delay of about 2-3 weeks, during "Chinese New Year celebration".

AliExpress is such a big organisation, that they have already big stock of products in warehouses in Europe itself,
centralised in some European countries. (E.g. in Germany). So many "general" products, even are delivered in "days".
(AliExpress general service for their customers is better organised than any Dutch company.
If you have complaints, or order is not complete, it will be resolved "in no time").

Comparable as for "Amazon" - they do have several European websites.
If I can not find a product on the "Dutch" Amazon website, by the same account I login to a "German" Amazon website.
By reseller you can always check if they send it to your own country. (Within Europe mostly no problem).

Hi Cunha,

Rack in pinion drive is only safe horizontally. Any tilt vertically and its not safe since all the weight of the system is resting on the lock brake, a small lever or knob that generates friction on the gear. Novoflex usually uses a knob to apply friction as a brake. Forget to tighten the lock and their could be a big problem if you tilt the camera up or down, the camera will move to the end of the system travel since there is nothing to hold it, the focus knob will just turn freely until the camera hits the end of the rack.

A lead screw type drive can mount in any direction, the load will not cause the camera to move on its own, not even one millimeter. Still they usually provide a lock but its usually not needed.

Also rack and pinion drives seem to need service a lot since the rack has exposed teeth, the grease gets contaminated since its exposed, and is wiped off. The lead screw is usually a fine tread and is located in the middle of the chassis away from everything so lubrication is never an issue.

Also a lead screw type drive its very easy to adjust drag or pre-load, its designed that way. You can make travel stiff or free. Rack in pinion drive relies on the same lock mechanism to provide pre-load so there is no way to dial in a certain amount, you have to adjust it every time.

Hope I didnt miss anything.

Best,

Robert

I agree with your statement, but in a Nikon Focus-Block(and lots of other microscopes) there is finally a rack and pinion drive :wink: . But the pinion is driven by a dampened planetary gear with high gear ration, so it is self locking. I also think a rack and pinion can handle much more dirt before clogging and malfunction than a threaded spindle and survive longer with lacking lubrication.

The great drawback is, that without an additional transmissin for the pinion, the travel is related to the circumference of the pinion. And even for a small 5mm pinion we get around 15mm of travel per revolution. That's too much for hand bracketing in small increments.

Hi Robert,
thank you very much for the explanation, it makes perfect sense.
Nothing like knowing about things to be able to make good choices.
:-)
Best.

By the way; returning to our friend's original subject in this post, are Cambo's solutions for the GFX of quality? They are more expensive than Novoflex and/or the old bellows, but they are modern pieces, with adapters, lenses and I assume good service.

As for Cambo solutions: E.g. Cambo Actus.
Cambo Actus do have several options, that also other vendors have within their product assortment.
So check several options and prices first.

The more short base plate, in this video example, IMO is not long enough for macro usage.
Cambo Actus B to Actus G
https://www.youtube.com/watch?v=FxiuCKx ... eIndustrie
Check also:
https://www.captureintegration.com/seei ... mbo-actus/

Looking at other pictures at Cambo, at least there is a more long base base plate.
Used in a vertical position: https://www.cambo.com/en/repro-system/actus-repro/

Check picture 1 = more short base plate Fuji GFX:
https://static.cambo.com/Images/Actus_R ... _105_w.jpg

Check picture 2 = more long base plate Canon
https://static.cambo.com/Images/Repro%2 ... Long_w.jpg

So comes with an extra part - (and to be paid extra?).

To be noted: As for vertical reproductions, Cambo offer also its own macro tubes including a Focusing Helicoid.
With the camera to be fit directly to the reproduction mount - without extra Actus parts. By the thought the less parts, the more stable.
(But.... As an extra note: The tripod mount / back plate of a Fuji GFX is sensitive for damage, as already noted within another subject).
https://www.youtube.com/watch?v=tOsfSXM ... eIndustrie

Swebo TC-1 OOBE --- (TC I guess = "technical camera":
Another alternative as for Cambo Actus with comparable options "and more" is from Swebo.
Already mentioned more early as a macro rail only. E.g. TC-1 OOBE used by Jim Kasson
https://blog.kasson.com/the-last-word/swebo-tc-1-oobe/
https://blog.kasson.com/wp-content/uplo ... .25.50.jpg

And field test experiences using the Swebo TC-1 : https://blog.kasson.com/gfx-100s/first- ... webo-tc-1/

The focusing gear ratio is substantially slower than the Actus with the regular focusing gear, and a little faster than the Actus with the fine focusing gear. The TC-1 uses the excellent Swebo knob with rapid movement assist, which works great here. There is no need for any finer gear, and you can do gross focusing moves at least as fast as with the Actus regular gear.

And check follow up experiences by the green redirection line more at the bottom of each web-page.
Extra to be noted as for the length of the base rail:
https://blog.kasson.com/the-last-word/u ... extension/

(Far) more cheap than Cambo Action, and full Technical Camera movement options.
https://www.aliexpress.us/item/3256803504515042.html

By the central spindle movements of the back standard, as already noted and comparable by the Swebo macro rail only.
It could be far more precise than the Cambo Action „base“ setup as for focusing (in meanwhile edit of above experience pages):
https://www.cambo.com/en/actus-series/a ... ew-camera/

However Cambo do offer also an extra micro focus adjustment for the Cambo Action model.
But by that becomes more pricy, as these parts has to be added (and paid) above the Action model itself.
https://www.cambo.com/en/actus-series/a ... ra/ac-380/

As from my own vision (used a Sinar P2 technical camera for years), this Swebo TC-1 could be the edge.
Hope this info give more room overthinking several options. ;-)

The Cambo cameras are great if you want to use it as a technical camera with precise movements.
For macro stuff they're "okay" but IMO unnecessarily complex, big, heavy and expensive and as Babylonia pointed out - overall don't have a very long extension.

Their repro stuff is really only for repro-not really for macro and I would agree that some of these mounting methods are a bit precarious, especially the way they expect you to mount the GFX with a long tube and the lens at the end is borderline idiotic:
Image

Yes, the camera will probably be fine, even though there have been reports of tripod mounts getting damaged that's really only due to shock/trauma and not during normal use. You can find ripped out or broken tripod mounts with just about every camera brand and format (just look for the Olympus EM-5 III for example). The GFX is admittedly not perfect but not worse than most others. The difference is that you wouldn't think about mounting a long tube/lens combo on a regular SLR camera, because it doesn't look like it can support that weight/force. But the GFX cameras look much more robust, even though they're really "just" upscaled 35mm cameras and a lot of GFX lenses are used without lens collar. But they're actually pretty light weight and with a close center of gravity.

Back to topic: If you want to take macro photos, bellows are the more logical option, either adapted 35mm or medium format.
