I've just completed viewing projected results from my K-3 lens testing v2.0.

Here are the findings. I shot a ISO-12233 chart at 4:3 at a distance that would fit the entire chart.
I only go up to 10points in resolving power on both vertical and horizontal.

Collimated Meteor 17-69 f1.9

@ F 1.9 - 7+
@ F 2.0 - 8+
@ F 4.0 - 9
@ F 6.0 - 10 *BEST*
@ F 8.0 - 8- ( I guess it start to loose it sharpness after f 6.)


Uncollimated Meteor B 17-69 f1.9

@ F 1.9 - 8
@ F 2 - 8
@ F 4 - 8

(Lower sharpness at zoomed-out distances)


Super Takumar A 50mm 1.4 (not SMC) - Honywell Branded

@ F 1.4 - 5+
@ F2 - 6
@ F4 - 7+
@ F8 - 8+

Super Takumar B 50mm 1.4 (not SMC) - Asahi Branded

@ F 1.4 - 6+
@ F 2 - 8+
@ F 4 - 8+
@ F 8 - 9+

Zeiss Pentacon 50mm 1.8 - MC

@ F 1.8 - 7+
@ F 2 - 8+
@ F 4 - 9+
@ F 8 - 9

Ricoh Rikkenon 1.4 55mm - MC

@ 1.4 - 6+
@ 2.0 - 8
@ 4.0 - 8+
@ 8.0 - 9

Vivitar 28mm 2.5 - Non MC

@ 2.5 - 6+
@ 4.0 - 7
@ 8.0 - 8

And the Winner ......


Mamiya Manual 55mm 1.8 ver A.

@ f1.8 - 8+
@ f2.0 - 9+
@ f4.0 - 10



Apparently the GDR Pentacon and Manual Mamiya/Sekor together with the Du-All collimated Meteor Zoom seem to be very sharp. I don't have to many wide angles for M42 to try.

I have a 35mm Flektogon MC and a 50mm Pancolar MC GDR on the way to try.

Judging from that list NO wide angles would be more accurate.

Could you expand? Is there something in the numbers I'm not seeing?

Or are you commenting on the fact that I don't have another wide-angle lens to compare the 28mm vivitar to? However I rounded out what would be "pseudo 28mm" with the Meteor 1.9 as comparison.

I do have a 28mm Spiratone, but I looked through it via the ground glass and the internal reflections made my chart look like "new war of the worlds" hazy/halated look - I decided not to kill the film on what I knew was going to look very bad anyway.

Zeiss Flektogon Jena 20mm F2.8 MC is available for the M42 mount. Though commentary is that the F4/20mm Flektogon is the sharp one. I'm wondering when they'll release the 25mm 2.0 for ZS mount.

I'm still looking for the 17mm Belomo (vs. the 16mm) supposedly the bokeh on that prime is super (but it is rare).

Ah nevermind,

I've re-read it, and what you meant is I am not in possession of any wide angle lenses vs. not too many. vs. wide angle lenses would not be any more accurate than the results I have as the numbers indicate some sort of a general fault.

Thanks for these results!

I have a few of the lenses you tested and my eyeballs pretty much agree with your test.

It would be interesting to test some of the really wide lenses, my Peleng 8mm seems very un-sharp, love to see where it falls.


By the way, for anyone else needing a chart I found this... there's a link to a PDF on there.

Yes, 28mm and 35mm aren't wide angles in 16mm format.

20mm would still be a normal lens.
Some east European cameras, Kiev 16U and Czech Admira 16 use 20mm for their normal lens.
