A new 35mm f2 Biogon or "Bokeh king"

Semilog, I own and love the 2.8 and was just curious what DN thought compared to the f/2...

and it is not almost as small as the color skopar... not even close! :)

It's about 6mm longer. The same length as the skopar with the little screw-in hood. I guess it comes down to whether you think 6 mm is a lot. There's a comparison photo of both in one of the Biogon-C threads.

Compare both lenses to either of the 35 ZF's ! ;)
 
Only thing not mentioned here about the Biogon is that for bright lights at night, it will produce a "star" pattern. I think this is a Zeiss look that shows up in other lenses in their line, related to lens coating.

leicashot - awesome images! I regularly get gas for a faster 35 than F2, and really don't need to see images like those!

Sunstars result from diffraction off of the aperture blade edges, and can occur with any lens that's partially closed down. Odd numbers of aperture blades give you stars with twice as many points as blades, and even numbers of aperture blades give you the same number of points as blades.

The stars will be clearer (higher-contrast) with lenses that efficiently suppress veiling flare.

Saw it all the time with my Summilux ASPH.

Yes the Nokton is excellent, and I enjoyed owning it alongside the Biogon-C for a small and fast combination. I do however find the 35/1.4 ASPH is a great combination of the two, but must agree with other posters that besides the vignetting, the Biogon-C is the best performing 35mm I've ever used.

As a comparative note, the new 35/1.4 ASPH which I briefly tested is a little better than the older ASPH as it
s field curvature is minimised and sharpness at close distances is therfore improved slightly. But still, it doesn't have that look the Biogon-C creates, which is hard to put a finger on, other than saying it's one hell of a lens! Honestly, there are three Leica lenses that have astounded me since using rangefinders for the last 17 years. 1 is the new Noctilux, 1 is the 50/1.4 ASPH (which honestly I find boring in character due to it's perfection) and the other is a non-Leica lens - you know which one.

they all grow when you hood them Roland. So small becomes a little bigger. That is why to me the size of a lens is less of a concern to me, and why I just have stuck with my Ultron.

Agreed. However, I have yet to make the v3 flare. The recessed front and six elements (only) help I guess, compared to v4.

A good 35/1.7 is a phenomenal lens, of course.

Roland.

Check how small a 35/2 can be:

This is my v3. Built like a rock.

Very sturdy and beautiful, however I prefer the V2 for only one thing above the V3 and that is its little f-stop tab, no other lens afaik has this little tab and it comes in really handy when you have to change the f-stop while a sunhood is on the lens. That said, most people stay away from the V2 (and V3) because of its bookeh fingerprint. Although I must admit that the clear fingerprint can sometimes be obtrusive, on many other occasions it puts down a really fine pictures - this is also the cause that from all the summicrons the V2 is the cheapest.
 
i wish people would stop calling the pre-asph the "king of bokeh". wide open and close up, it's more like the "peon of bokeh". :D

...which Mike Johnston was careful to note, when he bestowed upon it the epithet "king of bokeh."
 
joe, Rover, Darren, et al:

In LTM with an adapter? Cousin to the Rollei 80/2.8 also for rangefinder cameras?
 
yes, it's a screw mount lens that came with an ltm adapter and cousin to the rollei 80 (which i have never tried or even seen in person).
