I mixed with Pentacon Embarassed
But they seemed to be good lenses too?


And I want to excuse myself - I asked about a Revue lens, and I simply didn't made it in my head to get there: Revue(non). It's pretty much the same, I think - my bad Sad

Regards!

Thats good to know, thanks.

I'm struggling with the Pentacon 29 f2.8; I read about unsharp edges, and if I look here, I can see it very good... in the Gallery you linked above this is not that visible.
I read that this is a Problem with Crop-Cameras (like mine) :/

Regards

Look a Yashica 28mm f3.5 ML lens + a Contax/Yashica adapter or Olympus OM 28mm f3.5 + OLympus OM adapter both are better deal. for a good Pentacon 28mm need a bit luck.

[quote="CameraRick"]Hi there guys,

When a lense is called "electric", it means the same than "auto", right? I saw a Pancolar electric 50 f1.8 for 12€, but I don't know if I could use it.

Regards[/quote]

DOH, no.
"Electric" lenses are useable only on Praktica VLC and PLC series cameras for open-aperture metering. Frankly, if you have the option between a CZJ or Pentacon electric and non-electric lens ... if both are multicoated, go with the non-electric lens. The pins tend to foul on the actuators of some m42 cameras.

You have to use your lens as a pre-set, manual focus lens. The "electric" makes no difference.

And, I think Zeiss Jena lenses are over-rated. Honestly, the best lenses for the money are Pentax Takumar.

I've owned them all - incl. schneider, rollei etc. The only lenses I would rate as superior are Leica Summicron. The rest is all hype.

[quote="CameraRick"]Yeah, I heard that.
But why are there Pancolars 50mm f1.8 sold for 10$? Even in this forum, that makes me curious - or are they simply "cheap and good"?

Regards[/quote]

Well, you are lucky. any pancolar for $10 is a good buy.
That said, the MC versions are quite good... the earlier zebra versions are absolute dogs. At least you can still re-sell it for $11...

Hi there,

there's an auction for a Pentacon 29 f2.8 right now (poorly labeled, so not many will find it).
Can you tell me if M42 is the only mount this lens was built for? The Seller don't knows the mount.

Regards!

Hi there,

I just forgot to thank you guys - sorry for that. I'm really happy to have you helping me out Smile

It's a shame, so many lenses and so little money - I didn't bought anything (only two cheap lenses on a flea market for 20€), but I'm looking around everyday. It's hard to seperate the good from the bad, and then the pricy from those I can pay for Very Happy

I just got an offer for a CZJ Flektogon 35mm f2.8 - it looks like my 50mm Tessar, silver barrel - which I can pay for. I read about it here: - click -
Is this "foggy" vision a general problem at wide open? I just want it to use it for film, so mostly wide-open; if this isn't possible though, it's not that interesting.
One of the lenses I buyed on flea market was an Auto Revuenon 35 f2.8, it does it's job (hey, it was 10€...) but is a bit "glowing" on wide-open (very light things in a photo have a light glow of it's own color). I wanted to get rid of this lens with the Flektagon.

Regards!

The package contains a "PORST compact reflex" camera (I'm not really into analog photography), some filters (POL, Sky, Macro, some stepp/-down rings), a tele-converter (2x by Hama) and a camerabag. But, more interesting, some lenses:

MC 1,7/50mm (actually I don't know the brand, I think it's a Porst, too)
Porst Weitwinkel MC 2,8/35mm auto
Porst 2,8/135mm auto
Revuenon Weitwinkel 2,8/35mm
Beroflex Auto-Zoom 70-140 mm (don't know the f-stop)


I am actually selling one Porst compact reflex S my self (on eBay)
Very nice camera, one of the most compact M42 cameras ever made.

Anyway, for the above lenses I can help you with 3 of them.

1) Porst Weitwinkel MC 2,8/35mm auto.
That is the one I am selling with the camera.
A very nice and sharp lens. Well-built but a bit heavy. All-metal construction except the aperture ring. It gave me surprisingly good result on my digital SLR's

2) Porst 2,8/135mm auto
I used to have this lens. I sold it a few months ago.
Nice lens. A bit soft wide open (as expected), sharp f/4 and above. Also a heavy lens, metal construction. I would buy it again if I wanted a 135mm f/2.8 with very good performance/value ratio.

3) MC 1,7/50mm
If this one is a PORST too, I used to have one. The best thing about this lens is that it was very very small. Nothing special performance-wise but not bad either. Soft @ f/1.7, reasonable sharp @ f/2.8. Sharp @ f/4.
A pretty typical standard lens you can used as an experimantal portrait lens on your digital SLR.


One thing you should also consider is that PORST was a German firm that sold rebranded lenses from Japan. This means that they were many different lenses under the same specifications (for example my PORST 35mm f/2.8 may be totally different from the 35mm f/2.8 you found).

The good thing is is that PORST seemed to rebrand only good quality lenses from highly regarded Japan manufacturers (like Mamiya, Cosina etc).

I say go for it. Make your experiments and keep the camera and the good lenses for your digital SLR. The lenses you may not like you can keep sell them cheap.
