ULF > Macro options?

Does anyone have any information regarding the close focus of the big apo-Tessars? 900/9 and 1200/11

I own the Apo-Tessars but sorry I do not understand your question....

How close to the lens can I place the subject and still achieve focus? Or a different question that’ll give me the answer I’m looking for, what is the maximum magnification with those lenses?

While I have your attention also do you know the image circles?

I was chastized here years ago for not using proper Macro lenses

FYI I have several now

Macro is all about magnifation of subject to larger than 1 to 1 onto the recording medium

If I want to FILL an 11X14 FILM I need a very good lens, lot's of light and fiddling

Macro is not copying a wall with tiny medium, aka film

I will post some now

I may not have made it clear in the thread, apologies.

There will be no wall copying, the stretch goal is a tintype headshot at 40 x 50”.

The time may come where I have to accept that the “right” lens doesn’t exist and improvise, but I’m not there yet. I just know I’m going to need a focal length in the vicinity of 1200mm.

It becomes very difficult and expensive real fast

Good luck

Thankyou, If it was easy and cheap everyone would be doing it.

I can’t explain my motivation, but this feels like the next step for my lifetime project which started on 35mm film 20 years ago and has progressed through 120, 4x5 & 8x10 film, 8x10 Polaroid and Digital 4x5 composite. These big shots will be challenging and expensive but also, with any luck, spectacular.

Once I know what I, doing I’ll be mounting it on a truck or trailer and travelling my country with it. It’s my moonshot.

There are some tables in this catalogue from 1890 showing the focal length, bellows draw and head sizes on the ground glass. Maybe they can give you some ideas?
