Semflex Oto 3.5 Type 31
Posted: Tue Apr 21, 2020 1:22 pm
Hi all,
A long ongoing project finished... a French TLR medium format, Semflex Oto 3.5 (Type 31).
It has a Berthiot Flor 75mm f/3.5 as taking lens, Tessar type and coated, this exemplar has multiple cleaning marks on the front, still I think it does right.
OREC shutter up to 1/400, high speed are halved after CLA, from 1/100 to 1sec are fine.
The camera has the double exposure prevention, crank winds and cocks the shutter. Loading is done positioning the first frame and after that it's done by winding.
Mirror and ground glass were fine and you can find this guides for helping your composition.
The only problem I couldn’t find a mechanic problem is the overlapping of few frames, my bet is winding strokes were too fast, anyway checking later with a technical roll I decided to make a fatter spool and avoid any kind of overlapping again.
The camera came with a ready case in good shape.
What I like the most (besides the photos taken with it) is that the crank strokes can be done with the thumb (one time and another until it locks) and of course that elegant grey leatherette (rubber in fact), the design is still very attractive the camera looks great
I took few photos with the camera.
Bended tree.
Sprouts and a tree.
A kids game.
Path of light.
I like them very much, closest aperture was f/8 the first photo, others at f/5.6 or f/4.
The camera is very well made, it's not a Rolleiflex in the guts but I haven't seen broken or bended parts, as per lens, it handles very well au par Tessar and Xenar ones, I have one photo with backlight and I can barely see any flare.
Another camera from this manufacturer I like is Semflex Studio, a telephoto TLR camera with a 150mm f/5.6.
Let's see how it goes
Thank you for looking,
Alex
