Hello
Sinar P or P2. P for Perfect (wel... but almost)....
There is a Sinar probe to meter light in the image plane (with Gossen or Minolta meters).
...
They are heavy. Yes.
Focal probe is very good system (like TTL system in SLR), I use Broncolor one with happiness...
I haven't been convince by minolta way to show measurement, same for Gossen (or SINARSIX).
Broncolor tells you to open or close your exposure by of a number of "stop", much more easy to use, in some condition, it takes real shutter speed for measurement...
(you fire with the probe, real aperture, real speed, real flash, real light and it tell you i.e. to open 2 5/10 stops you can apply to speed or aperture....)

Hello
my point of view about SINAR vs rest of world...
SINAR is the best due to modular system (as TOYO, ARCA or Linhof) and to copal-sinar shutter (as no-one else) ...
This copal-sinar shutter is a very good accessory that allows use of plenty lenses without shutter! a must have!
I have 4~5 SINAR (F-4x5, Norma-4x5, P-4x5, P-8x10, S2-8x10) and 4 copal-sinar shutter.
(But for usual lenses, prefer shuttered one as possible and use copal-sinar shutter only for exotic lenses like apo-ronar, petzval lenses, repro lenses, enlarger lenses...)
The P (or P2) is very heavy and rigid camera that done for still life photo. Really easy to use.
The F (or F1 or F2) is lightweight but more "springy", very good for field photo and extension use with P/P2
The NORMA is rigid as P/P2 but less versatile for still life photo than P/P2 due to tilt/shift disposition...
For still life photo, I like to use a standard bellows + a wide angle bellows near spring-back to be sure not have vignetting with huge tilts...
In still life photo you will be quickly in proxy photo mode (G=1/2 to G=1/1) and for perspective problems, long focal lenses are bester.
With 240~360mm focal lens, bellow for G=1/2 is respectively 360mm and 540mm, more than standard bellow occur (400mm without tilt)...
6x12 back.
I have two: SINAR ZOOM-2 that allows 4.5x6 to 6x12 format and Da-Yi.
The SINAR is a good choice as it is insertable back but I prefer the Da-Yi because I opened it to 56x118mm (instead 56x112mm of SINAR and Da-Yi right from box).
In studio, for still life, Da-Yi (even not opened) is enough but removing spring-back become quickly boring...
On Youtube, I done some video on SINAR but in French (name start with "T011a SINAR" to "T011f SINAR")

Hello

I don't understand why my last pictures uploaded didn't appear? is it a problem of size/weight? (33 Mo instead of 6 Mo for BW)
thanks

Hello
Rollei film, like RPS-25 or Retro 400S have very clear base.
I never try to inverse them
