Seems to have a bit of vignetting in the pics... how come?!?

Thats what you get using wideangles.....light fall-off (it i snot something bad, many people including me find it nice to get a bit darker sky at the edges/corners, or a bluer sky).

89200024 is likely due to the lighting that is more focused to the building......(well, the area around it is the atmosphere)

unlikely that it is so pronounced with a leica lens.
maybe he used a lens hood that was not appropriate.
or maybe too many filters stacked in front. vignet not always present so cannot be the lens.

I do not think the vignetting is due to the lens.

More likely inappropriate use of filters or incorrect placement of the lens hood.

Nice pics. Which lens were you using?

Fongster · 6th August 2005

some of the last few pics (night and indoor of dog) is with a Notilux 50mm.

The rest were with a 50mm f2

Never knew Nocti vignet so much. So it's true that the corners are 1 or 2 stops less than the center. Nice though, have a very different look to crons. The crosses at the roof top has a look which I cannot describe.

Strange, my noctilux does not have this vignetting.

Thought you were talking about the first few pics......don't know about the two nightshots. Taken with a 50mm? Try to test the lens against an evenly lit wall, or white paper.....make sure it is evenly lit! E.g. on a cloudy day outdoor.

Vignetting by a hood or filters will appear as very sharp edges, not those fuzzy edges we see here.......

Another reason could be the printing lens you are using, did you use the same enlarger lens and aperture for all pics?

I assume you used the Noct at full opening for those nightly images? Very possible that the lens has severe lightfall-off at full opening, it is a chunk of glass! Light from the edges have to pass a higher mass of glass to reach your film..........

prints were scanned from the photolab, that could be it too,

I dont have my lightbox and other tools here in Singapore.

Its hard to tell light fall offs from night pix. It could be the film exposure lattitude that causes it. I just find some pix are a little too soft for a Leitz.

Wisp · 12th August 2005

The last three seems to follow the noctilux characteristics alright at full aperture.

As for the others, it could be the lens, or it could be the scanner. I've had wet prints that looked alright but when I scanned them in using my scanner, the vignettes somehow appeared, especially if you form an S curve characteristic or push the contrast up.

I'll take my bet on the scanner. Cause it seems that even the 50f2 got it at I assume is probably at f8-f16 (depending on the lens, but it looks that way).

What other pics there are?

Wisp · 12th August 2005

(P.S: Not all leica lens are pin sharp. Look at the summarit/summar or even a summitar at full aperture, and the edge to bokeh defination is pretty much gradual. Some like the Thambar are actually meant to be soft.)

Agreed, may not be typically sharp and contrasty like the Japanese optics but they are seen with great resolution power that render details in the pix. Some of the pix are just too soft as compared to a lot of well taken Leica pix that I had seen.

That being said, I am not doubting those Leica pix but it seems that details were lost through post processing of the images. It could also be due to inaccurate focusing which takes time especially for new users of rangefinders
