Do you ever feel the need for speed.

The Noctilux natch. But crazy speed isn't really my top priority, I find f2 a good enough maximum in most circumstances (provided it's actually a usable aperture on that particular lens).

If they were giving out Summiluxes though, I'd sure be in the queue.
 
Noct! Duh! I'm constantly shooting at f/2 with 3200 speed film, and I still often have to go to 1/15s. Sure, a 'lux would be a good start, but I've shot a roll with a Noct and I love it!

Lets say you could have any one of Leicas fast lenses If you could have just one fast lens which one would it be. :bang:


If JUST one LEICA lens is the criteria, then I have no doubt about this, being a 5cm FL man: the Summilux 50/1.4 pre-asph. Man O man, do I love its signature. And yes, I have one and it will be used by me until it is no longer useful....

But why not the Noctilux? Well you said ONLY one LEICA fast lens, and the noctilux is not as useful all-round as the Summilux imo.

So some practical considerations have to be taken into account.
 
I had a Noctilux, and sold it, because I didn't find enough use for it. I didn't find the 50mm focal length important enough to privilege it with an f/1 lens, while all my other focal lengths were slower. I do have Summiluxes in 35, 50, and 75mm focal lengths, and find enough use for them to keep them around. F/1.4 seems sufficient for my needs. With a fast film in the ISO 1600 range, when the light is so low as to need F/1, I can't see to focus in the first place.

The main issue I find with low-light photography is not that there isn't enough light; it's that the light is not concentrated where I need it, for an effective picture. And when the light is in the wrong place, F/1 won't put it where it should have been.

My favorite topic! My fastest is the Canon 50/0.95 - which is a very specialized lens indeed. I love Rob-F's comment about the light being where I need it. I could justify the cost of the Canon based on where the light is, but I still can't justify the Noctilux. I would not have my next favorite fast lens either - the 35 Summilux ASPH - except that I made a scandalously good deal a while back. The CV 40/1.4 is an amazing value! But I also like the signature of the old Summarit, and it gives plenty of speed with Neopan 1600. Now, let's wait for Ned to weigh in.
