I'm just falling in love w/ Pentacon lens, especially their M42 version which can be used on digital SLR (w/ adapter). Its quality for sharpness & colour rendition really easy to say stunning.

I'm not familiar w this kind of lenses which are now easier to get via e-seller over the internet seller.

1. Pentacon auto 50 f1.8 vs Pentacon Pancolar 50 f1.8 (Carl Zeiss Jenna)
2. Pentacon auto 29 f2.8 vs Carl Zeiss Jenna 29 f2.8

I really confused which can not identify the difference of these lenses, because look identical in term of their shape and colour of their glass coating.

Many thanks,
RTogog

General consensus is that the Pancolar is better.
I used to own both lenses and I can confirm.

Pentacon 29mm is a decent lens that becomes good (or almost) at around f/8
I never heard of a Zeiss Jena 29mm lens.

Yes, I can confirm this, the Pancolar is such a nice lens. Still my most used 50mm lens. Much better than the Pentacon 1.8/50 - in my opinion. Wink

I saw on Ebay, Item number: 350212660450.

I already have Pentacon version & itchy to get CarlZeiss Version (Jena).
It looks identical.

Both lenses are good, however there are differences:

1. Pentacon is more vatiable in quality (optical), this variability affects mainly corners (softness, CA).

2. Really good copy of Pentacon can have slightly higher resolution in cetre than Pancolar, but lower contrast and significantly softer corners. Pancolars are overall sharper and more contrasty.

3. Pentacon has slightly lower axial chromatic abberation than Pancolar.

4. Both lenses have good, but different bokeh. Pentacon is more retro. Anyway, I'd prefer Pentacon for bokeh pictures taken stopped-down. Both lenses has 6-bladed diaphragm, but in Pentacon bokeh hexagons are almost invisible:

Pancolar / Pentacon, both at f/4:


(please use this pictures only for bokeh comparision, they are not perfectly focused and overxposed)

5. Both of the lenses aren't very good in terms of mechanical quality. Both have problems with oil on diaphragm. Pancolar is also prone to stiffnes of focusing ring. Pentacons are smoother.

My personal opinion is, that Pentacon is better for portraits and stopped-down close-up shooting, while Pancolar is better for wide-opened usage and stopped-down infinity shooting, where corners really matter.

I prefer S-M-C Takumar 50/1.4 Embarassed

I can not agree NO-X any more. Addtionally, Pancolar costs about 5X to Pentacon.
I got Pentacon/Pancolar/SMC Tak. Pancolar has great color/bokeh while SMC is realy sharp and fast.

Thanks Attila - so does the 'P' on the barrel actually mean Pancolar?

if mount is M42 means Pentacon I think. In latest years they made nasty tricks they labeled everything to Carl Zeiss Jena like Sigma and other unknown lenses too.

Again, my thanks, and yes, the mount is M42.

The lens just doesn't have that CZJ 'feel' to it, and the Pentacon feels the same - not flimsy or anything, just lacking Laughing

They both came in a bunch of free lenses so I'm not too concerned about quality issues, but they've been added to the list of lenses to be tested this summer...

Many thanks for the "in schedule" review. We wait for the findings of these hidden potentials for digital era.
