The final color rendition, however, will really depend a lot of whether or not one uses filters, which RAW converter is used, which profiles, etc. So, color can look a lot of different ways but I can't think of any reason that I would not use that lens for color work.

lct Posted September 17, 2007 Share #3 Posted September 17, 2007 Bought the 21/4 P too recently to be sure but my feeling is it looks more prone to IR contamination and/or magenta or red saturation than my Leica lenses, on the R-D1 that is and without IR-cut filter of course. Any clue about this? Link to post Share on other sites More sharing options...

Any clue about this? Hi LCT, The lens itself has very little to do with IR sensitivity. It's really a sensor issue. Cheers, Sean Link to post Share on other sites More sharing options...

Hi Sean, yes that is what i thought as well in the first place but i have rarely had such results with my Leica lenses. Here with a Summicron 40/2 for instance (same PP, no filter). Really my feeling is that the 21/4 is more 'reddish' difficult to say otherwise. I'll have to use it more to be sure. Link to post Share on other sites More sharing options...
sean_reid Posted September 17, 2007 Share #6 Posted September 17, 2007 Hi LCT, The light itself (as it hits the subject) is warmer in the first shot. The CV lens may also, itself, be warmer than the other lens. How are you setting WB? That whole sense of warm and cold color, of course, changes with WB. I don't think IR factors into this.

lct Posted September 17, 2007 Share #7 Posted September 17, 2007 Advertisement (gone after registration) Same sunny WB, both raws anyway, same conversion but different light yes. Not so different though... Well i'll have to use this 21/4 a lot more obviously... Great little thing anyway. Link to post Share on other sites More sharing options...

Well i'll have to use this 21/4 a lot more obviously... Great little thing anyway. Hi LCT, When you say "sunny" are you using a preset WB? If so, try sampling from a fairly neutral gray in each frame and see where you are. Cheers, Sean Link to post Share on other sites More sharing options...
lct Posted September 17, 2007 Share #9 Posted September 17, 2007 Thanks Sean yes was a preset WB but i could have chosen tungsten as well with no big difference given that i shot raw no? I used to follow your advice in my youth when i was not so lazzy, now i use iCorrect with not so bad results so far. Perhaps it come from this? I doubt, i doubt my friend but again i'm at the beginnig of the learning curve with this little lens so i'd better go out and take some photographs. Cheers.

johnwolf Posted September 17, 2007 Share #10 Posted September 17, 2007 Hi Mauri, Here's one of mine. It's metered off the road. I keep an IR filter on it. I'm not much of a wide-angle shooter, so I don't use it too often. But when I do shoot with it, it always makes me wish I'd do more. I'm very pleased with the color. I've hand-coded mine several times with marker. It's easy but does not last, so I gave up. Are you using a finder? I turn my head to see the viewfinder edges, which are close enough. If I used it routinely, I'd definitely get the finder. Post some pics with it when you can. John Welcome, dear visitor!

These are all using an IR Cut filter, Daylight WB, ISO 160, Adobe Photoshop. Great lens! Welcome, dear visitor!

lct Posted September 17, 2007 Share #13 Posted September 17, 2007 Great pics indeed. Much better than with the R-D1 as far as vignetting. Do IR-cut filters cause cyan cast with this lens and if so how do you avoid it? Link to post Share on other sites More sharing options...
cme4brain Posted September 17, 2007 Share #14 Posted September 17, 2007 Great pics indeed. Much better than with the R-D1 as far as vignetting. Do IR-cut filters cause cyan cast with this lens and if so how do you avoid it? Thanks for the comment about the pictures. The cyan cast is seen in lenses wider than 35mm when an IR cut filter (I use B+W486 filters) is used. If you use a coded lens, or hand code a non-leica lens (as I do with a sharpie on this 21mm), then the camera software automatically corrects for the "cyan drift" by adding magenta in the corners. Make sure your M8 menu selection for the lens says "On +IR" meaning you have told the M8 you have an IR-cut filter on the lens and you want the camera to detect what focal length the lens is.

lct Posted September 17, 2007 Share #15 Posted September 17, 2007 So you used the same coding as that of the Elmarit 21/2.8 asph right? Link to post Share on other sites More sharing options...
cme4brain Posted September 17, 2007 Share #16 Posted September 17, 2007 So you used the same coding as that of the Elmarit 21/2.8 asph right? Yes, that is correct. It is my opinion that as long as you get the correct focal length of the lens, the vignetting correction for both brightness and cyan drift is pretty good. You could fine tune it I suppose to the exact proper lens (some will argue that vignetting is dependant on f/stop, and that may be true if you only shoot at the maximum aperture that you code the lens for), but for me any 21mm lens designation produces the same result. You would have to be an expert like Sean Reid to note more difference. At least my amateurish abilities do not. Link to post Share on other sites More sharing options...

Do IR-cut filters cause cyan cast with this lens and if so how do you avoid it? Yes, much less vignetting than with the R-D1. That's true for almost all lenses that vignette on the Epson. Cyan drift occurs with all 21 mm lenses when IR-cut filters are used. The filters don't cause a cyan cast. The corrections come from coding or CornerFix.

Then a simple 21mm menu in the M8 firmware could suffice for photogs using Leica and non-Leica lenses obviously. Thanks for sharing. Link to post Share on other sites More sharing options...
wlaidlaw Posted September 18, 2007 Share #19 Posted September 18, 2007 I have come to the conclusion that the colour rendition of Zeiss, Leica and Voigtlander lenses is sufficiently different that until such time as the AWB is fully fixed, it pays to reset manual WB with either a card or better an Expodisc, every time you change to a lens by a different manufacturer. This is accentuated if like me, you are also using UV/IR cut filters by Leica, B+W and Heliopan. Given that it takes about 15 seconds to set a manual WB with an Expodisc, I feel it is a real time saver to do this rather than messing about at the conversion from DNG or PS at a later stage. I have been amazed how much more consistent my colour renditions have been since I started using an Expodisc as a matter of course. Wilson Link to post Share on other sites More sharing options...

Thanks for sharing. And which 21 is "obviously" chosen... nice blending of threads fella! There are those who find the CV 15 does better with the WATE 21 firmware correction too. So, please keep this "menu item" drizzle to the already growing number of threads it draws(sorry Sean!). The CV 21 renders well, yet plays best to film and its archetype of light play. rgds, Dave Link to post Share on other sites More sharing options...
