In my quest of searching ultimate 100mm short tele (see here) I decided to gave a chance to my Pentacon 2.8/100mm electric which already laid three months on shelf.



For one month it stayed in my bag and I tried to use it as much as possible and here are some (better) results.
After the month I've get very comfortable with this lens and it's focal length.

First some quick observations:
+ BOKEH, it's really a cream machine.
+ very sharp already from f2.8.
+ tactile sharp at f4 and onwards.
+ good contrast.
+ natural colors (I still like Leica more for portraits, but very good).
+ control - I do like the stop down button much more than A/M switch. It's much faster to operate.
+ price - I've got my copy for 20€ with stuck aperture. Otherwise ~ 50-70€.
+ in good light conditions it shows some of the "3D" power of much pricey lenses.
+ low CAs. Only wide open in realy high contrast scenes.
+ small and discrete (only slightly longer, than Meyer or CZJ 50mm lenses).
+ did I mentioned the BOKEH?!

- micro-contrast is not on pair with my best lenses (Leica, CZJ).
- 6 blades aperture - it sometimes degrades the bokeh.
- bokeh CAs. But on pair with other non-APO and much pricey lenses in this focal length (Zeiss Makro-Planar 2/100 anyone?).

To sum it all, it's best Meyer (Pentacon) lens I have and I won't be probably far from truth when I say it's one of the best Meyer lenses ever produced.

First portraits (it's last Meyer portrait glass!):

Great shots, love the poppies! There's not many examples from this lens on the site, so a great contribution Smile

Nice work. Mine just wouldn't focus properly so I cannibalised the mount for use in my Primotar 135. It's good to see that they are capable of nice results.

I completely cleaned and relubed my lens. Now it's much nicer to use (unfortunately still not on pair with West Germany lenses).
Most Meyer lenses have very special green and blue tones rendering. And my Samsung likes them Cool

Nice series. I especially like the first poppy image.

You appear to have focused slightly in front of the eyes in the seventh photo... Wink

Best wishes, Kris.
