Hexanon 50 vs Zeiss Planar vs Summicron

Trius, apologies for the delay in my reply - long day 🙄

Alkis: How can one judge black levels from a shot made on negative stock that is then processed through scanning, PS or equivalent and prepared for the web? The only real comparative test, it seems to me, would be to shoot transparencies that are matched for high values and see evaluate where the low values fall, both by viewing and by densitometry.

Strictly speaking you can't judge. In a sense, you have to take my word for it (if you are so inclined). I have seen prints from the Planar and I have scanned quite a few negatives and I thought that there was an emerging pattern in what I saw. Photos were offered here for illustrative purposes - as evidence, not proof.
 
There are hardly any modern 50mm lenses out there that can be viewed as bad lenses optically. Most modern 50mm lenses are sharp and contrasty. So what is left then? Pick a 50mm lens and go out taking photos with it. The rest is pretty much an exercise of words that don't mean much.

You know, I never liked the 50mm focal length either, until I got a ZI. Then I started shooting with it about 70% of the time. Even when I had my M3 I didn't appreciate the 50. That being said, I have a hard time keeping a large variety of the same lens. Yesterday I had four, but today I'm down to two.
I think that is due to frame line of 50mm, most people (like me) enjoy shooting 50mm on rangefinder because of frame lines been small enough to see whats happening around while composing but big enough to see and focus properly! but final picture is different story 🙂
 
hexanon is inferior to the two others mentioned IMO. The build is great but the contrast doesn't stand up to the zeiss or the cron. The zeiss build is weak, not much better than the VC>

The best in the 50mm range is the Leica cron. Small and yet affordable. This isn't the lens to compromise on.

So you've owned and used extensively a 50/2 ZM Planar? Did it fall apart on you? What sort of use did you put it through? What sort of problems did you have with your copy after extensive use?

I did not find the build quality lacking in my copy...

Of course, the lens you have at-hand at the crucial moment is the "best" lens.

I don't remember the exact aperture, Ted, but I believe magus is on the mark - f/2 or f/2.8. That was with the Rigid. The current formula summicron would have rendered more contrast, but for b/w I prefer the older version.

When you say the Hexanon "contrast doesn't stand up to the zeiss or the cron", what exactly are you saying? These samples only? Capability of the Hexanon? Contrast too high? Too low? Microcontrast? What do you think of these shots? A very different look from what are posted in this thread.

Alkis: Thanks for the reply and I do take your word for it! 😀 I never thought you were offering any shots as "proof". FWIW, any difference that may show up under precisely controlled conditions would probably be a result of glass and coating differences, primarily coatings I would guess. Then again, I'm not an optical engineer, just like you.

Because I had the devil in me today I looked up standard lenses on www.photodo.com in MTF terms the summicron is second only to the Planar 45/2 the zm 50/2 is not tested. But I noticed that the canon fd 50/1.8got a very good score (4.4). You could buy that lens and a decent body to go with it for less than £100! The pentax smc 50/1.4 f got 4.6 -the same as the summicron and is 1 stop wider -does anyone know how much this costs?
 
Toby:

I am currently using SMC lenses after not getting close to them for many years. In fact, I have the 50/1.4 SMC mounted on the Pentax ME Super, while I have the 50mm/4 macro SMC on the Spotmatic F and the 28mm/3.5 SMC on a Spotmatic. Each lens is tack sharp and a pleasure to use.

I am not surprised that the 50/1.4 SMC has such a high score.

I know this was directed to Trius, Earl, but I see those shots as having that Hex "look." I see it very distinctly in the blacks and the tones just above black and up to middle grey. What we call it, I don't know. I don't find it offensive at all. I like it and IMO it is not an indication of a poor quality lens. Those shots look great (good job, Gene). Look at the bokeh in those shots. It's gorgeous! I'm not selling my Hex lenses anytime soon.

Thanks Ray

Thanks Ray

It's a good photo, and that lens is still very sharp wide open. The subjective bokeh may be a little harsh, but I can't tell without side by side shots from other lenses. It may just be fine, and an interesting OOF pattern back there.
