Another 50 mm.

[LCT]

I would like to assist my Leica 50 Summilux II another 50 mm which is more compact and also has a different yield from the Lux [...]

As you have a fast lens already i would choose a latest Elmar 50/2.8 if you like the Tessar look or a Summarit 50/2.5 which ia almost perfect but has less character than the former. Both are contrasty with little flare and a smooth bokeh. I have a CV 50/2.5 aso but it is softer. Another idea would be a Summicron 50/2 v4 which is very small but it is outperformed by the Summarit. Same for the Summicron 40/2.

Thank you for your thoughts and suggestions. I will try to prove some lenses to decide. I will be happy if someone still wants to add his opinion.
