Carl Zeiss Distagon 25/2,8 Rollei QBM mount

I got this lens in original state. as we know, focusing infinity of Rollei lenses mount has problem with adapter available for DSLR. so at the moment I cannot shot infinity at wideopen to f8. I can achieve infinity at f11.



wide open at close distance performance is amazing. the color and contrast too. see sample below
There's no words that show coating (eg. HFT or T*) in this lens. as for as I know, HFT mark was request from Rollei for their camera. T* is original Zeiss coating.
Then why there's no such mark on this lens? just my opinion, this lens is in Rollei mount, so no T*. I think Zeiss made this lens as sample for Rollei, or in other word they made not by request.
We can see the lens is coated. and its performance show it.
I cannot see CA with this lens. yet. cool!




Using Lens turbo with this lens





good lens to shot product like this. available light, no flash or additional light.

Tair 11A 135/2,8 & CZ Sonnar 135/2,8 T* AEJ

I have the Zeiss for long enough, and I always satisfied with it. Now I have Tair 11A, which is said to be one of best 135mm lens ever made.
Phisically, Tair is heavier and little bit longer. all metal stuff, while Sonnar has rubber grib for focusing ring.
All have internal hood, but Tair is shorter, not long enough.
Blades? Tair has 20  blades, sonnar has 8.
Closest distance, Tair 1,2m Zeiss 1,6m
Both has CA and sharp start at wideopen.
This is not scientific test, just few minutes comparison in my backyard.
Camera Sony NEX5, white balance sunny, landscape mode.
There were other images, but speed was various so the tone cannot represent the real comparison. this happened because light was changed often.
No edit except resize & auto sharpen (in irfanview)
In the first comparison we can see Tair has more green color. while Zeiss has more pastel color

Fresh B/W from Sony NEX5 at 1,2m (closest distance of Zeiss)

This one was at F 5,6

My conclusion?
I like 'em both.

It has CA at wideopen like other fast lenses, but sharp enough (sharper than my Hexanon 85/1,8 at wideopen). You have to be careful to obtain right focus, thin dof :)

Konica Hexanon 28/3,5 AE & Schneider Kreuznach Curtagon 28/4

First of all, Curtagon was my favourite  amongst 28mm lenses. I just curious of the hexanon which said to be good one. Just got my Hexanon few days ago. Find other post of both lens in here( Hexanon)  and Curtagon, here.




  • Based on This Schneider site My Curtagon was made in 1967 while Hexanon AR (which has Focusing ring with checkered rubber inlay, Smallest aperture 16, 7 elements in 7 groups, Green AE mark and Round AE lock button) according to This Konica site was made around 1975.
  • Dimension: Curtagon is  smaller but it's little heavier
  • Closest focus: Curtagon has 0,25m mark, but it can be turn closer. while Hexanon has 0,3m.
  • Sharpness in wide open; I can say curtagon is little bit better, maybe half stop slower make different. Hexanon is sharp too, even at infinity.
  • CA control ; Hexanon has lots of CA, worst in wideopen, reduced little stopped down. Curtagon has little in wideopen
  • Contrast: Hexanon has better result, later production bring newer coating I guess.
  • I wrote before that "I haven't make comparison for infinity distance yet, but I think both has almost similar result". Then I realized something different. It's about edges sharpness. Curtagon win in this case. Hexanon soft at edges. (at least I tried at f8)

Here we go the short comparison I took this morning
