Recently bought Gaoersi 4x5 camera with 4 adapters ( for 58mm, 65mm, 90mm and 150mm lens). Pictures are in attachments below.
Trying to choose proper lens I have found few problems:
1) As you can see on the pictures 90mm adapter has larger hole then the others (Copal 1 size , I think). Is there any possibility to use Copal 0 lens on them? As I know there is only one 90mm lens on the market with Copal1 size ( Grandagon 90mm/4.5) , very heavy and very expensive. Is it any remedy for this? Can I exchange front element (with hole) from another adapter?
2) On Gaoersi website (http://www.gaoersi-camera.com/htm.php?nowmenuid=4126) "Lenses Can Use" there is no lens 65mm ?! Is it true? I have 65mm adapter produced by Gaoersi company...and I belive they made it for some lens, question is which one?
No answer from Gaoersi Company on my e-mail with these questions.
This Forum is my last hope...
I'm looking for somebody who can help me...
Sorry for my poor english
