Chamonix 4x10 & 450mm lens?

[rich caramadre]

I was looking at the specs on the Chamonix 4x10 and it has 420mm max extension. Has anyone successfully used a 450 lens on one? I see they have extra extensions available but are there enough bellows?

You can contact Hugo Zhang who is the US rep for Chamonix cameras either here on the forum or at hugoz_2000 AT yahoo DOT com. I'm sure he can answer any questions you might have.

Chamonix does offer an extension board for your 4x10 for $180.00, which I'm sure Hugo will advise.

On a similar note I have a Chamonix whole plate camera with its maximum bellows extension listed as being 600mm. Wanted to use my 600mm f/11.5 S KangRinpoche lens (in a Copal #3) on the camera. It is mounted normally on a Sinar lensboard. By the specs would seem that focusing on anything closer than infinity was not possible. In practice the lens was able to focus 30-40 feet away. For me, I have a "top hat" Sinar lensboard which I need to modify to be able to mount the Copal #3 into. With this combo I should be able to focus 16-20 feet away which I will easily be able to live with.

I have a Chamonix 4x10 and use a top hat lensboard with my 450. Check Ebay for other sellers of top hats.

Keith, How deep is your top hat? I thought of that but was worried about possible vignetting.

I have a tophat Board that allows me to use a 30" Artar on my V8 from infinity up to about 25' The V8 has right at 30" of bellows. I can also use it on the 11x14 which has 42" bellows with a flat board..

With an extension board, our 45N3 has a max bellows draw of 560mm.

Hugo, OP here. I was interested in the 4x10 camera. Not a 4x5. Honesty I'm surprised it only goes to 420mm. I find a 450 lens very useful for 4x10.

[Hugo Zhang]

Sorry I meant to write 410N3.

Im pretty sure the effective lens length limit of the 410N3 deals with the desire to have a compact form when the camera is folded up for storage and the limitations to length are a result of the shorter 4 inch height of the format. I have one and use a 450mm lens, but do use the extension that Chamonix sells/advises. I would rather deal with the extension piece than a top hat, but that is my personal preference. The extension is lightweight and packs easily and the bellows have plenty of capability for that length lens.
