Chamonix Extension Rack

[Richard K.]

Does anyone have a photo of this accessory or can point to a URL of one? Thanks! :)

I don't have a digital camera, so could only describe it. It is the piece of carbon fiber that attaches to the end of extension bed, and front standard attaches to it. Total belllows extension with the rack is around 500mm, which is close to the maximum for standard bellows. Extension rack is very compact and light. Camera is still pretty rigid with the rack, at least with my lenses. Adding/removing the rack takes 2-3 minutes.

The picture does exist on this forum, if you want to search... I remember commenting it's illogical construction - if you want to search in my posts...

You're right, those pics are blind now...

Thanks Will et al!:)

PS. It works great and I actually thing it is a simple easy to use design. I use it all the time!

Richard, mine was for 045 (small version), I believe that Will's is for 810 (and maybe larger), so you might just take look at his photo, but if you need to see mine, I can post it up.

Will, thanks for posting the photo. Can you tell me the length and width of the extension?
I guess you find it stable and rigid enough? I've seen such extensions that overlay the bed of the camera and are attached by 2 screws to the bed, leaving the one socket for attaching the front standard. Overlap length is variable by choosing which 2 holes on the base to attach to. VERY stable. If I find a photo, I'll post it.

Thanks Songyun. It is the larger one I'll need...

I have the 45n-1 version. The photo is from a for sale post for a Chamonix 8x10. I don't see why the 8x10 version would perform differently than the 4x5 version.

Here is the link to the for sale post: http://www.largeformatphotography.info/forum/showthread.php?t=54962

I would just ask Darryl, the seller, what he thinks.

My 4x5 version is very sturdy and usable at full extension.

I second that; my 4x5 extension rack works great with Fujinon-C 450mm f/12.5 lens.

and a third... works well and is simple.

My gawd that extension is HUGE!
There is no good reason for the plate to be that large/wide.
Length is the necessity.
There are other post concerning this DIY item of interest.

Anybody using this 4x5 camera with extension and a Nikkor 600T? I think the bellows is a bit shorter than for the 450C, but the weight is much higher.

Thanks.

Yike, I would not recommend it used with 600T, that is heavy... heaviest among all nikon T lens.

none of the pictures are accessible (at least for me).

Can someone post a picture again?

Thanks
