Trubute to VEB Pentacon & Praktica 德國M42相機老祖宗.プラクチカ カメラ wmv
Praktica (プラクチカ-)is a brand of camera manufactured by Pentacon in Dresden in eastern Germany, formerly within the GDR prior to reunification. Pentacon is the modern-day successor to Dresden camera firms such as Zeiss Ikon, and for many years Dresden was the world's largest producer of cameras. Currently Praktica is the only brand sold by the company; previous ones included Zeiss Ikon, Contax (now owned by the Carl Zeiss company), Exakta, Pentacon and many more.
The firm collapsed after German reunification but was resurrected in partnership with Schneider, and produces many products under various brands such as car industry products, 3D LCD screens, and still cameras and lenses under their own Praktica brand and also for more known international brands.
One of the first inventions of the firm, which is still known today, was the roll film SLR camera in 1936. In the east block countries the firm's products are more known than in the western world. They produce both budget lenses (mostly small, not very durable and having slow autofocus but good in optical quality) and higher priced products. They also produce optical equipment for the space programs of the US, Western Europe and the Russian Federation
1887 Richard Hüttig founded the first camera manufacturing company in Dresden.
1896 Zeus-mirror reflex camera with plate magazine as first single-lens reflex camera from Dresden by the company Richard Hüttig & Sohnhe
1933 EXAKTA 4 x 6,5, a small roll-film single-lens reflex camera using 127 film, was introduced by Ihagee Kamerawerk Steenbergen & Co.
1935 Contaflex: first 35mm twin-lens reflex camera with interchangeable lens and the first camera with built-in exposure meter was introduced by Zeiss-Ikon AG.
1936 Kine-Exakta: first 35mm single-lens reflex camera introduced by Ihagee Kamerawerk Steenbergen & Co.
1945 Heavy destruction of the 'Dresdner Kamerabetriebe' (Camera Manufacturing of Dresden) through aerial bombing on February, 13th/14th 1945
1949 Contax S: first 35mm single-lens reflex camera with built-in pentaprism viewfinder (world novelty), offering unreversed viewfinder image, introduced by MECHANIK Zeiss Ikon VEB, at that time a 'state-owned' company. It also introduced the M42X1mm screw lens mount for interchangeable lenses
The first M42 mount Praktica was built in 1949 by the Company Mechanik Kamera Werkstätten VEB Niedersedlitz which was founded as Kamera-Werkstätten Guthe & Thorsch GmbH 1919 by Benno Thorsch and Paul Guthe in Dresden.
In 1989 the Berlin wall was down; the GDR was no more; and a great name was soon fade into history. The famous Pentacon factory in Dresden was shortly closed and with it, unless something unexpected happens, the end of the Praktica SLR.プラクチカ- カメラ
The last Praktica film camera built by the VEB Pentacon was in 1990 Aug, it was the BX20S

REVIEW: Panasonic Lumix GF1
Want to buy one?
[Affiliate]
This is my review video of the Panasonic LUMIX GF1, easily the most unique camera I've ever had the opportunity to look at. It's similar to a DSLR in that you can change lenses, but the micro four-thirds system doesn't use a pentaprism or mirror, so it's not a DSLR. Panasonic calls it a DILC: Digital Interchangeable Lens Camera. I don't see DILC taking off as a term, but this camera is hot stuff...it's been selling out everywhere, and Panasonic is struggling to keep up with demand. It uses SD cards and supports SDHC.
The GF1 has a 12.1 megapixel Live MOS sensor (17.3 x 13.0mm in size), capturing JPEG or raw images at a maximum resolution of 4000 x 3000 pixels. It's also capable of 720p video capture (1280 x 720) in either AVCHD Lite or MJPEG formats. It can shoot in burst mode, up to three frames per second.

Titans of 6x7: Mamiya RZ67, Pentax 6x7 MLU, Bronica GS-1 compared
Hello, all!
The audio came out low for some reason, so crank the speakers.
In this video I compare the Mamiya RZ67, Pentax 6x7 MLU and Bronica GS-1. I try to illustrate size comparisons/differences to one another and their size relative to me. This isn’t meant to be a user tutorial on each system, though I do discuss each camera’s major components and mention some of the pros and cons to each system both from a technical and subjective perspective.
When I was looking to shoot larger negatives I began doing some research and these three stood out as the titans of the 6x7 format. However, I couldn’t find any images comparing all of them side by side nor could I find any videos that compared them. So, I decided to assemble some basic systems with each and work with them for a few months to see what I liked and didn’t like about each system as well as what stood out to me as benefits, shortcomings and tradeoffs. I finally had some time this week to put together this video with various camera angles to try and help share some of those findings with you.
Sorry, it’s long, but I hope you find this helpful.
NOTE: I'd been doing some research on the 645n prior to this filming as a smaller hand-held option potentially in the future and I had its 1/60th sync speed on my mind apparently. I've added annotations where I thought I remember discussing it in the video, but it's actually only 1/30th on the 6x7. My apologies.
As always, below is a “chapter” breakdown for the video. This is helpful if you are searching for something specific, but very useful should you wish to review it again in the future.

No espírito das ideias que merecem ser espalhadas, o TEDx é um programa de eventos locais auto-organizados que reúnem pessoas para partilhar uma experiência ao estilo TED. Em um evento TEDx, TEDTalks em vídeo e palestrantes se combinam para provocar discussões profundas e conexões em um pequeno grupo. Esses eventos locais, auto-organizados são chamados TEDx, onde x = evento TED independentemente organizado. A Conferência TED fornece orientações gerais para o programa TEDx, mas eventos TEDx individuais são auto-organizados.* (*Sujeito a certas regras e regulamentos).

Contax
Contax was a camera brand, started in 1932, noted for its technical innovation and wide range of Zeiss lenses, known for their high optical quality. The final products under the Contax name were a line of 35 mm, medium format, and digital cameras engineered and manufactured by Kyocera, and featuring modern Zeiss optics. In 2005, Kyocera announced that it would no longer produce Contax cameras.

135 film
135 is photographic film in a film format used for still photography. It is a cartridge film with a film gauge of 35 mm, typically used for hand-held photography in 35 mm film cameras.
The term 135 (ISO 1007) was introduced by Kodak in 1934 as a designation for the cassette for 35 mm film, specifically for still photography. It quickly grew in popularity, surpassing 120 film by the late 1960s to become the most popular photographic film size. Despite competition from formats such as 828, 126, 110, and APS, it remains so today.
