Subject: Re: [Leica] more noctilux images

Hi Michael,

I cannot speak for Rei but as a owner of a Noctilux
I am pretty sure he cropted or manipulated the image.

Usually on a bright backgroud you see very strong vignetting (more than 1.5 
stops, I don't remember the exact figure) so that I was almost wanting to 
try a central gradual grey filter
for those shootings.

But as I am not willing to put a filter
in front of my Noctilux, i just stop down to 1.4 or 1.8 for these particular 
cases. Works fine.

The Noctilux is really a killer lens except for:
1) F1 vignetting on bright background, as I said
2) Weight
3) slow focussing (because you need to be precise at f1)

and you fast forget about these weknesses when you see the results :-)
