On September 7, 2024, at the annual photo fair of Saint-Bonnet-de-Mure, France, I found this Meyer-Optik Görlitz lens Oreston 1:1.8 f=50mm in M42 mount that I wanted to associate to my Praktica IV SLR camera body.
The lens was in acceptable condition for 20€ in the range range of price of my Praktica IV. Both were manufactured in Dresden, Germany in the year 1960’s. Oreston lens was marketed starting from 1965 in order to equip, in particular, the Praktica Nova that was anticipated to be produced massively by Pentacon for exportation (zeissikonveb.de/start/objektive/normalobjektive/oreston.html).
Oreston was a modern normal lens 6-lens double Gauss type, capable to compete with other foreign productions of that time, with a large aperture, automatic diaphragm mechanism, and optical performances that could not rival to Zeiss Jena productions (as the Flexon and Pancolar) but still very near at medium apertures.
For testing the lens, I loaded a 36-exposure black-and-white Fomapan 100.In the Praktica IV equipped with the Oreston lens. The lens was equipped a generic Yellow 49mm screw-on filter and a cylindrical modern shade hood for the views taken. The expositions were determined for 64 ISO instead of the nominal 100 ISO to compensate the filter light absorption, using an Autometer III Minolta light meter fitted with a 10° finder for selective measurements privileging the shadow areas or with the integrative dome for measurement of the incident light.

After complete exposure, the film was revealed using Adox Adonal (Agfa Rodinal) developper at dilution 1+50 at 20°C for 9 min. The film was then digitized using a Sony A7 body fitted to a Minolta Slide Duplicator installed on a Minolta Auto Bellows III with a lens Minolta Bellow Macro Rokkor 50mm f/3.5. The RAW files obtained were processed without intermediate files in LR and edited to the final jpeg pictures.
All views of the film are presented in the dedicated album either in the printed framed versions and unframed full-size jpeg plus some documentary smartphone color pictures.
About the Praktica IV camera :
I got the camera body Praktica IV and a set of related KDH Leipzig accessories from an eBay seller near Paris, France.. The whole arrived to me on January, 31, 2024, in Lyon, France.
The Praktica IV was designed by the prestigious KW (Kamera Werk Niedersedlitz) German company in Dresden on the basis of their previous Praktica FX SLR camera's. The camera was produced first under the KW name starting from June 1959 then within the Kombinat VEB Pentacon after the merge of the company in 1960.
166.800 Praktica IV and V (6 models) were produced until January 1966. Praktica IV essentially incorporates a condenser focusing screen plus a pentaprism. Due to the Praktica FX architecture the Pentaprism looks protruding from the camera body with an unusual style. It fits lenses with M42x1 mount and the mirror has no automatic return. The shutter is made of two horizontal curtains of rubberized fabric giving 1/500s to 1/2s plus B in two registers of slow speeds (1/2s to 1/10s) and high speeds (1/25s to 1/500s). The film is advanced coupled to the shutter cocking using either the right upper button or the rapid lever underneath the body.
The Praktica IV handles the "Auto" M42 lenses with the lever for automatic iris closing upon the release. Sequentially, when pressing the shutter release button, the diaphragm closes to the indicated value, the mirror is lift-off and finally the shutter is erased at the given value. If a non-auto (manual closing) M42 is used the pushing lever could be cancelled (declutched) moving a small red button to the right in the mirror chamber.
The camera camera came without lens but with a body cap and the original ever-ready leather bag with et "Ernermann tower" Pentacon logo. This model is likely the second Praktica IV essentially the same as the initial KW one with a different front plate. The camera was likely art of a collection and is completely preserved without use marks.
The KDH Leipzig (Kurt-Dieter Huffziger Foto- und Kinozubehör) accessories set included:
-A panoramic tripod head
-A set of three extension tubes M42x1)
- A big aluminum shade hood (screw-on 49mm) for wide-angle lens.
- A M42x1 metal body cap in its original box.
- An accessory shoe fitting the the Praktica IV eye piece.

As I was having a whole 'lotta' fun sewing the other day I somehow found myself sorting through my buttons. Now you should understand that button sorting is a favourite pastime of mine and I need no excuses. It gives me immense pleasure to sort them into their individual jewel like colours, their various shapes, sizes, whether they have two holes or four....... Maybe it's because I'm a control freak or possibly that sometimes I'm a Teaching Assistant- buttons are an excellent educational tool as well you know!

These pictures are from an old German magazines I found in a storage at work.
This is me stepping well out of my comfort-zone. I normally avoid button down shirts like the plague. As a large busted lady they are always a mine-field.
You either gape over the chest, or its huge and you swim in it, never flattering.
This one fits me nicely and doesn't gape as the fabric has a slight stretch. Also its slightly see-through so you can see my shape through it. Plus the little tie feature distracts in case any gape-age may occur.
(this picture does make it look like it gapes over my belly but its just my hands on my waist... honest... *shifty eyes*)

The is the first button quail. I'm unsure whether it's male or female- most of the time the males have that white patch on the throat but in some mutations females do as well. If you've noticed the bare back, according to the breeders they pluck feathers from each other to add to the nest. They will grow back!
This one is a bit braver than the other one, as it didn't try to run.

I think I have seen all 5 in the conservatory now. Each one is completely different looking from the other 4. The name finally came to me - Button Quail. Actually it turns out they're not really quail at all. Just about every website deals exclusively with their behavior in captivity. They are bred, bought and sold and kept as pets and in aviaries. The 5 in the conservatory are become much tamer than they used to be. This is the best link I could find.....
