Hi,

I have a LF "point and shot" camera which have a limited bellows extension where I can mount up to a 120mm lense ( without extensions ).

I was interesting in buying a copal 0, 240mm lense, so in that matter I have to buy extensions tubes (another 120mm in tubes right?)

On ebay I saw some extension tubes that the guy sell them in 20mm, 30mm and 50mm sizes.

My question is, can I buy for exemple 2 x 50mm and 1 x 20mm? or perhaps 2 x 50mm and 1 x 30mm to have more margin (?) to focus on infinity?.

Do I have a limit to the lenght of the extension tubes that I can put on a camera?

Can I have problems with this 240mm copal 0 lense to focus?


Thank you in advance
All the best
