Linhof backs to Sinar?

[Vaidotas]

I have Linhof 4x5 back with 6x9 reducing back and planning to use it on Sinar F2.
DIY adapter is on my mind but maybe there is original one?
Anyone has experience merging Sinar with Linhof?

[Bernice Loui]

Sinar 4x5 has an industry standard graflok back..

Linhof made Super Rollex backs in both 4x5 graflok and priority Linhof 2x3_6x9 rotary backs which are specific to Linhof..
Solution to this is to use the 4x5 graflok version of the Linhof Super Rollex back.. done.

There is little to no rational reason to convert the Sinar back to using the Linhof special version of the Super Rollex.. and these versions are rare, difficult to obtain. Vast majority of these Linhof Super Rollex backs made and currently on the used market are for 4x5 graflok.

Linhof made adapters to use the 45 rotating backs on the Kardan cameras... you would just need to figure out how to secure it to the Sinar. I am not at all familiar with the Sinar.

Thanks, Embdude, this is exact part I’m looking for.

Bernice, I’ve must be more specific, my Linhof back is for 6.5 x 9, 2 1/4 x 3 1/4 sheet film.

Sinar lens board with proper hole will go for Linhof 6.5x9 back base for starters.

Pictures of what this idea is helps.

Generally, specific to Sinar P. P2, X the rear frame holder mount can support a wide variety of frames, from there it is much a matter of bellows that fit the rear frame to the Sinar front frame.

Looks like a Linhof 2x3_6x9 rotary back. If yes, the frame can be mounted to a standard Sinar lens board then installed on a Sinar 4x5 frame.. Some machine shop time required.

I'm guessing this is to use the Sinar with Linhof 2x3_6x9 super rollex and other Linhof accessories..
Curious idea, have the same, might give this a try at some point if there is enough motivation to experiment and tinker.

[QUOTE=Vaidotas;1671150]Outer dimension is 16x16

The square part (with the 6x6 quick release circle inside it) is attached to the 4x5 back board with 4 screws. remove them (and keep track of any shims) and screw it into a Sinar board... done!

[Vaidotas]

Already done.
The solution was so simple but overlooked.

Thanks a lot!

Sinar DB lensboard as a base, almost straight fit, I need to enlarge a bit the hole.

Looks great! just curious were there any shims?

There were very large shims under my 5x7 to 4x5 back... but I haven't had occasion to take apart the 45 to 69...

Congrats. Are you going to shoot this with 6x9cm sheet film? I can tell you that is a HOOT.

As you can see I have a nice smorgasbord of B&W 6x9 emulsions. Even ORWO NP22 I bought from a Guy in Bulgaria who had a ton of it. BTW It's Good OK film

[Vaidotas]

Embdude, what left unused - Linhof 4x5 back base plate, undocumented in photographs. Except that plate, there were no shims.

Daniel, nice set up. And Makiflex and Peco Jr are outstanding cameras. I'm keeping an eye on them.
Meanwhile the plan is to keep things as simple as I can manage with existing gear.
Sinar is less comfortable for longer hiking of course.
I cleaned the dust from that 6x9 back when realized, that times when 120 roll film was cheaper alternative to sheet film in this format is already gone.
Six Linhof 6.5x9 double sided sheet film holders and few boxes of expired film is on my disposition now, and plans to cut more film from 5" rolls. And Combiplan tank for developing.
And I'll check that Bulgarian guy, thanks for reference.
