Thanks Jsherman, it means a lot

I forgot to mention that was taken with the M 85mm wideopen also.

The M and K are different optical formulas, so the fact that you didn't care for the K doesn't concern me. And frankly, I wouldn't need the 120 to be better than the 135 - just a little shorter and a little faster, as advertised. As I've mentioned before, I rarely really get the maximum sharpness out of my lenses anyhow shooting in low light. Between the loss of resolution from high ISO noise and the slight motion blur I'll virtually always be seeing in my concert photography, it almost doesn't matter how sharp the lens is or isn't (to a point, of course).
I didn't know that you're going to use the 120mm exclusively for concert photography. Sure, at ISO 1600 the sharpness will be limited anyway but I intend to keep my lenses for many years and exchange camera bodies at 3-5 year intervals. It's just a matter of time before we're able to use ISO 1600/3200 without sacrificing significant sharpness.

If I buy a K 120mm or M 120mm I expect it to perform just as good or better than the 100mm F2.8 and 135mm F3.5, especially considering that the 120mm usually costs more. My copy didn't impress, so I sold it. It could very well be that the M 120 is better than the K 120, but that would surprise me as the k-lenses are known to have a slight edge in sharpness.

Kind regards

Yep, that is possible.

I did have my share of consistent bad copies, but those are SDM zoom lenses. :ugh:

Exclusively, no, but it would be my main reason for owning it. It would be shot wide in low light - and even if high ISO performance improves in the future, musicians won't start moving less, so I'm still likely to be sharpness-challenged. In other than low light, I'd mostly be shooting stopped down. You're right than M lenses are rarly considered improvements over K. So I'm curious - did you test at variety of different apertures?

Yes I did. The 135mm was noticeably sharper at F3.5 and F5.6. They equaled out at F8.

However, close to minimum focus distance (less than 2 meters) the K 120 was sharper.

After getting rid of the 120mm I got the K 135mm F2.5. This lens is very very sharp. It's sharper at F2.5 than the M 135 at F3.5.
But, it's much bigger (but still not too big). I have also tested the A* 135mm F1.8 which I found uncomfortably heavy.

Kind regards

lars,
that's a very nice lens. too bad it's not an AF. the only reason that prevented me from getting one. although it's resolution is really great.

calling all you color callibrated screen users!

The images I posted on the last of the last page..... do they look practically sepia to you? I made them warmer than normal B&W's though not straight up yellow....but according to a friend on his callibrated moniter they are borderline sepia.

thoughts?

Looks pretty close to sepia for me, and as far as I know my monitor is calibrated very accurately in color and gamma.

Although I must say it is a tad bit on the yellow side, its not too saturated, but it gets slightly into green in some areas, when I slide the hue -4 in photoshop it fixes it though.

The last dog shot you posted is one of the best I have seen! Now that it is mentioned, it does look a bit on the sephia side to me, but my monitor is not calibrated either.

I have made a few attempts at monitor calibration, but remain very unhappy with the crude tools to achieve it. There must be a way to calibrate a monitor without feeling like a judge for platform diving!!!

Well, they're sephia to me, but a bit on the brown-yellow side. I guess you wanted a more coffee-bean brown ?

Kind regards
