155 Grandagon f6.8...

[Capocheny]

Greetings,

For a Grandagon 155 f6.8 that is presently mounted in a Sinar Auto-aperture board (in other words, it's not mounted in a shutter,) is it possible to simply unscrew the elements from the board and re-mount them into a Copal 1 shutter?

I'm almost/pretty sure that this is the case but I need confirmation on this.

Thanks in advance for your input.

Cheers

Yes it is possible and just have to get the sticker for the f stops from Copal or Rodenstock!
I have it in a compur 1 electronic shutter and it is a very sharp lens and like it very much!
It is also heavy and you can also use it as wight for body training!
Good luck with it! Armin

Hi Armin,

Thanks for the note...

I'll second Armin's recommendation. Performance is outstanding but it is a very large and heavy lens when mounted in a Copal 1. Mine weighs 3 pounds, 4 ounces. It never gets very far from the car.

Hi Armin, Dave,

Can't be much heavier than my Symmar 360 f6.8 with the gigantic 105 mm front element!

Cheers

I have a 360 5.6 Componon, with a front mounted packard, I share your pain, and it doesn't go too far from the van, nor does the C1, either.

Hi it has also 105 mm front so you can use the same Filters! ;--))))

I have a 480 5.5 Meyer Gorlitz doppel plasmat in beautiful shape that is at least twice that. I have been dying to try it, but I don't want to rip the standard off my V-8. I could take the front element off and have an 830 F-11 but I need to build an extention box for the back. What I need is like a copal No. 6.

Armin,

True... but if I had more than one lens of this size, I'd have to either hire a Sherpa or bring out the baby buggy jogging stroller!

John,

Your lens sounds like "major weight-lifting equipment!"

I recall seeing a huge, huge lens mounted on a Sinar P a few years back and this lens was so heavy that it had to have a special cradle built underneath to support the thing. THAT was an amazing sight!

IIRC, it was a 1200 mm, or something like that!

Cheers

If you think the 155 is heavy, wait till you hold a 200 f/6.8 Grandagon in your hands. It makes a Copal 3 shutter look small.
