Pentacon is a very good lens , sharpness is not everything. Pentacon is sharp enough for most purposes if not easy to make it sharp in RAW. Bokeh, smooth rendering is first class in my opinion. _________________ -------------------------------

With Pentacon you focused on front leg thus body of tripod seems unsharp wide open.
Pentacon is super sharp wide-open if you have clean and well adjusted sample. It might sound as bragging but i have collection of 20 pieces. Only 5 of them were obtained in cool state from Ebay. Others didn't perform optimally and various elements had to be cleaned from mostly haze (condensation residue). Even when initial state is resurrected and everything seems OK, 30% of Pentacons do not reach top sharpness due to different causes. _________________ ---------------------------------

Spiro know something that for sure, thanks for him this lenses slowly reach their position what they deserved. I don't think so a few EUR is right price for them like MC going mostly. _________________ -------------------------------

I don't know if it's a characteristic of the lens or if some of the elements have adhesive around the edge that has yellowed with age? _________________ - Dave

I saw only with yellow edge if I remember as well, not so common lens I saw only 2-3 copies not more under 4 years locally. _________________ -------------------------------

Best is to use a lightmeter, make the pictures in manual mode with all the setting identical. This way you can rule out any exposure errors. _________________ Asahi Pentax: 35/3.5-50/1.4-55/1.8-135/3.5-200/4

I agree. Camera bodies meter differently on different alt lenses. If your exposures end up different, then at least equalize them in a RAW program. I think those crops of the overexposes 'flares' (they are not flare, just highlights) are quite useless now because the exposures are so different.
I am surprised by the big differences in apparent DoF, by the way.
Anyway, thanks for the interesting test.
My rating from best to worst:
Bokeh smoothness: Pentacon, Sonnar, Komine (some bright ring)
CA-correction: Sonnar, Komine, Pentacon
Contrast is difficult to judge because the exposures are different.
I also agree the Pentacon was front-focused (on the tripod foot). |

Exposure is the same for all three lenses, starting from the first measurement I closed a diaphragm and down one point the shutter speed. But the lenses work differently in different areas. The Komine has a tendency to blow up the highlight, and the difference of the coating, is very important.
Is precisely for that, to correct the extreme.

I agree that cameras, measured differently with different lenses.
But here there was only one measurement, and was with the Sonnar at f3.5. Everything else was correction of scale.
But I think I made a mistake, the WB was automatic.
Still, I'm sure you appreciate the strengths and weaknesses of the lens.

I have to disagree on that. Ok, the camera measured different with different lenses. But then again you would need to correct it.
If you correct it in a raw developer, you can have blown out highlights that you can not recover anymore.
To be completely correct, you need to use identical setting for every part of the test including development,….
Framing, lightning,.. they can all have an influence on the measurement.
The best is to use the same lightning, exposure, wb. Then test 3 lenses at the same aperture and repeat for the next set.(with different exposure offcourse)
I also have lenses that I know screw with the cameras lightmeter (my Jupiter 11a is the worst). _________________ Asahi Pentax: 35/3.5-50/1.4-55/1.8-135/3.5-200/4

Use the same exposure value in the three lenses. ISO 100, f4 at 3600 - the same value for all three. Without any correction.

In my opinion the Komine is close to the Sonnar. If I think there is much difference of coating. That is very important. I have seen many lenses Komine, have this feature. Overexpose highlights.
Tomorrow I upload a photo of the lens, before returning.
