Hi Walker, I'm looking forward to those lens comparison pics. Should be interesting.

Hi Walker,
Thanks for the info on the Meyer oreston lenses.By a strange coincidence the second lens I bought for my S1a was a Pentacon 2.8/135. IT certainly is a fine optic and holds it's own with more modern and more expensive lens.Look forward to your comparison pics.

Hi,

Pentacon lenses are really interesting.

I have been told, but have not been able to verify, that though the majority of Pentacon lenses were made by Meyer, some Pentacon 135mm M42 lenses came from Carl Zeiss in Jena. These were Sonnars, and I have an f/3.5 135mm Sonnar which seems to be identical in every respect to a friend's f/3.5 135mm Pentacon, including the built-in telescopic lens hood.

I also have another lens which is also identical but this is just labelled Carl Zeiss Jena DDR, and is marked MC, for multi-coating, in red. No mention of the word Sonnar.

The earliest 135mm Sonnar was an f/4 in the 1930s with Contax bayonet fitting. The earliest were uncoated, but those made after about 1936 were single coated. The f/3.5 135mm came later in M42 mount and is quite easy to find. The f/2.8 135mm Sonnar was still later and both this and the f/3.5 carried on as 'Carl Zeiss Jena DDR' lenses without the name Sonnar. Very similar looking Pentacon f/2.8 lenses, but not quite identical, were made by Meyer and were believed to be all Orestors. Most Prakticar lenses were also Mayer Orestors though some may have been Orestons and the long focus 200mm upwards) may have been Orestogons. There was a whole family of Orestxxxx Meyer lenses, all of very similar design with nothing to choose in performance.

Sonnars were also a family of lenses originating for the Contax I in 1932. Most were six-glass designs but there was a later modification to a five-glass design. Some of these were made when single coating came in, but most the five glass versions were after multicoating was introduced. I believe there were also some four-glass Sonnars made for movie cameras.

How many Sonnars were labelled Pentacon, if indeed any were, I have no idea. I was told by someone in Dresden that if the MC for multi coating on a Pentacon is in red it is a Carl Zeiss Jena lens. If it is in white it is a Meyer lens, but again I haven't got any other authority for saying this.

Pentacon?

Buy one and try one - you won't be disappointed.

Hi,I am a newbie and even though this thread is old I hope it is active. As an avid collector of Pentax stuff and lifelong photographer I have just obtained what is probably my best buy yet from a Goodwill store.Pentax H1a mounted on dual release pistol grip,to Novoflex bellows c/w 105/3.5 Novaflexar lens. this combo is in mint condition and has obviously hardly been used and stored carefully. The price for this gem? $60.00.I shoot mainly macro and this will allow me to shoot hand held instead of the hassle of a tripod.

I have great respect for you all that work on your cameras. I took apart my SRT-101 at ~ age 14 and Humpty couldn't it back together again. I also took apart my Vivitar flash -- with built in NiCads -- and shocked be-jeezus out of myself. That's where my restoration career ended.

When I have something that I am not able to get working, I set it aside for a while (sometimes months), and come back to it. Sometimes just having a fresh perspective is all it takes to have a successful outcome. Sometimes I have to repeat this procedure a few times.

There was nothing wrong with my units when I took them apart, I was just curious.

If it ain't broke, don't take it apart!

Johnny - that's a classic story! You, without a doubt, must have shorted a capacitor that resulted in your shock. You probably heard the tell-tale 'snap' too.

That's like the time I decided to convert my 1975 Ford pickup from full-time four-wheel drive to driver controlled. I bought a kit from some guy in Georgia. Got under the truck, unbolted the rear of the transmission housing and pulled it off while lying on my back. When I did, about 10,000 tiny needle bearings came showering down on me. I said--well I won't repeat what I said. There was no way I could every find all those bearings--or put them back in the proper place. I called the guy that sold me the kit (he worked out his home). I explained what had happened. He said, "Don't worry, you don't need those bearings anymore." He must of been right because when I sold the truck 10 years later it still was running fine.
