Great bargain, and a wonderful shooter. The 28/50/135 combo is underrated. And those CPC 28's are pretty good.

Here it is - my biggest, and most primitive SLR:
Ensign Roll Film Reflex. by Berang Berang, on Flickr
Shoots 6x9 on 120. One shutter speed. Max aperture f7.7 - mirror slap that causes land slides. I'll do a full report once I get the test roll back.

Mike, my first SLR/serious camera was a Yashica TL-Super that I bought discounted as a demo model, in 1972, when I was a university student. Mine had the f1.7 Yashinon lens.

Something a bit different for a change...and please tell me if I have got anything wrong!

In the foreground is a Pentina M. This is a leaf shutter interchangeable lens SLR. In the background a Pentaflex 8 from roughly the same period. Though obviously different colours they both share the same body covering. The Pentaflex is a highly spec'd, fully featured, very heavy 8mm camera with what I am told is an Altissa mount?? (no idea how or about register).
The internet tells me that the reason for the existence of a leaf shutter SLR was to achieve higher speed flash sync for the electronic flashes that were then becoming more reasonably priced. I know not.
The Pentina is somewhat fiendish within. The shutter is just behind the lens and therefore must be open for viewing. The sequence of events when the shutter is depressed is, I think, as follows.
When looking through the viewfinder, the shutter is open, the automatic aperture is open, the mirror is down and a light baffle is in front of the film.
Press the button and...as far as I can tell...in no particular order
The shutter closes
The aperture closes
The mirror goes up
The baffle goes up
A baffle goes up inside the viewfinder (to stop any stray light)
And then the shutter fires.
Wind on and...
The baffle comes down
The mirror comes down
The viewfinder baffle goes down
The aperture opens
The shutter opens
Well, that is what I think happens. Please correct me if I am wrong.
At the moment the thing is very stiff, we shall see if I can improve it...hmm.

Having got it to work I realise I have the Pentina sequence wrong...but haven't quite worked out what is really going on yet.

The Mamiya RB SLRs have a similar sequence with a baffle and what not, but no auto-return mirror.

Man, I really like this one - maybe more than my AE-1 Program.
