Hallo,

ich bin stolzer Besitzer einer CLE mit dem 40er Objektiv. Jetzt habe ich Gelegenheit mir aus Japan das 28er und das 90er mitbringen zu lassen. Dort ist die Auswahl und Qualität angeblich deutlich besser als bei uns. Worauf soll man da achten, von dem 90er gibt es wohl verschiedene Versionen und bei dem 28er weiße Ablagerungen im inneren. Hat sonst noch jemand Hinweise und Tips dazu?

Dies ist zwar kein spezifisches Leica Thema, vielleicht wird mir aber doch geholfen. Wenn es gar nicht hier her passt bitte löschen.

Viele Grüße, Bernhard

There are two Rokkor's 90mm to consider, the one made in the fifties for the Minolta CL and the one made in the eighties for the Minolta CLE. Both very good lenses, the one for CL is a clone of the Leica Elmar-C 90/4 but i prefer the one for CLE that is less prone to flare (pic). The Rokkor 28/2.8 has only be made for the Minolta CLE. It is one of the most compact 28/2.8 lenses ever made and is a very good lens indeed. just beware that it may develop schneideritis i.e. white spots on the black paint used to reduce internal reflections in the lens (pic). Mine has a bit of them but they have no effect on photos.

Hi @Bernhard685

I also loved the 40:2 Rokkor that came with my CLE and so I then bought 28:2.8.  For the 28mm there is only one choice and as @lct points out, there is a common problem of the 28s developing white spots due to the glue that was used I believe.  However, copies without the white spots are out there (I bought one).   If you see a clean 28mm these days it shouldn't (I've read "won't") develop the white spots now if it hasn't already.  Lenses we see these days without the spots may have been corrected by Minolta because I think they did accept them back for repair at one stage .

For the 90:2.8, I chose the CLE version not CL / Leitz.  CLE version is identifiable by "Minolta M-Rokkor" on the rim of the glass as LCT posted above (CL versions have Made by Leitz).  Highly recommended, I far prefer it to my 90mm Leica tele-elmarit, which I will now sell .  

I think this 28 + 40 + 90 is an amazing set for M mount and total cost is cheaper than a 35mm Summicron.   Common to find completely mint copies also in Japan as you have mentioned

Hello, thanks for the helpful answers. My son is currently in Japan with his Japanese wife and will surely find a nice 28 and a 90 CLE for me. I'll report in a month.
Best Regards, Bernhard

I meant in the seventies sorry for the typo.

I might add that as long as the sun or sky is not in front, the 28 is excellent. It really has gorgeous colours and such details on my M10-R. I found out that with a red filter the effects of Schnedeiritis disappear on my Monochrom...

I used the 40mm in preference over my 35mm Summicron on the M240. Such a good match.

My copy of the M-Rokkor 28/2.8 has not the same acutance as Leica-M 28/2 or 28/2.8 asph or even CV 28/2 asph but it is quite a sharp lens otherwise and moderate schneideritis my copy suffers from has no visible influence on IQ. Lens is pronone to flare when the sun or other strong light sources stand outside of the frame (link). May produce color reflections when same sources stand inside of the frame too (link) so better use live view with this lens to manage the flare, or refrain from shooting into the light.

My M-Rokkor 28/2.8 has only very slight schneideritis, just a couple of spots which are barely visible without a lupe. The dedicated 28mm lens shade makes all the difference as far as flare is concerned but, of course, add to the size of the lens.

I like much this little hood but i always use it and it was there when i took my shots above. In my own experience it makes no significant difference but it is not alone, Leica hoods can hardly do better in such situations. Better way i've found is to make some more shade with a hand or a hat but it is hit and miss as one could expect.
