If you print large (say 11x17inches or larger)Â and the bokeh balls are more than a few mm in diameter, you might be able to see them, but being semi-random noise they aren't too distracting. Â Still, a reminder that four ASPH surfaces introduces some challenges! 1 1 Link to post Share on other sites More sharing options...

It's not quite a scandal, but certainly a surprise for a premium-priced lens. Â That said, I would rather have the very high degree of apochromaticity and acuity that this lens offers than grain-free point source bokeh balls. Â But ideally we wouldn't have any trade-offs! 1 Link to post Share on other sites More sharing options...

sebben Posted March 10, 2021 Share #26 Â Posted March 10, 2021 Totally agree. How is the focus action? Is it gritty/jumpy like the 50mm ASPH? Link to post Share on other sites More sharing options...

Is it gritty/jumpy like the 50mm ASPH? Focus action is very smooth on my copy. Â The "haptic feedback" (resistance point) when you hit 0.7 m covers a bit of rotational angle, meaning that you hit the start of the "speed bump" as you turn from infinity right at 0.7 m, but if you are turning from MFD you hit the other side of the speed bump a bit earlier (short of 0.7 m). Â I probably would have preferred a simpler feedback mechanism that just conveyed a simple, smaller feeling of falling into a tiny divot at 0.7 m but the mechanism works reasonably well.

Stuart Richardson Posted March 11, 2021 Share #29 Â Posted March 11, 2021 Just like Leica to forget to batter those lens elements before they deep fried them... Fair play to notice it and discuss it, but in all honesty, if this is the trade off required for the performance it gives, it seems like a very minor issue to me at least.

crony Posted March 11, 2021 Share #30  Posted March 11, 2021 Hi, this thread made me curious ... I only have the Voigtländer Apo-Lanthar 2/50, the poor-man's Apo-Summicron. I did a series of shots with different bokeh-conditions. I found that the Apo-Lanthar shows slightly grainy bokeh now and then on the M9. One sees this, when details of a picture are enlarged, not when normally viewing the whole picture. Of course, everybody likes a good scandal, but one should (try to) be realistic and fair. I can live with the Lanthar performance, and could live with the Apo-Summicron quite happily ... --- If it really bothered me, I could always take another one of my 5 Leica M mount 50s ... Link to post Share on other sites More sharing options...

For starters, it looks like their is a 1º angle of view difference between the two when looking at the spec sheet: Leica 62.5º , Voigt 63.5º. I will venture a guess and say the Voigtlander probably does not have any haptic feedback once focussed closer than 0.7 as on my VM Ultron 1.7. I could be wrong though... When is the availability date of the Voigt? I guess they will let the APO-summi hype die down a little bit to have a fair chance. Link to post Share on other sites More sharing options...

I would have started with mentioning the $7050 price difference, but I am sure to most people 1° viewing angle difference and no haptic feedback for leaving the rangefinder coupled range are more important 🙂 (PS: I actually sent Leica an Email that it would be nice if the lenses focused closer and had a haptic feedback when leaving the rangefinder coupled range, so I am all for that) Link to post Share on other sites More sharing options...

onasj Posted March 12, 2021 Author Share #37 Â Posted March 12, 2021 Just to properly close the loop on this thread for those missing the discussion in the other threads, several of Steven's photos in his impressions thread show the same issue, and my Leica dealer heard from Leica that this property is normal for this lens.
