Bobu Posted December 22, 2011 Share #21 Posted December 22, 2011 Advertisement (gone after registration) The Luminous Landscape article addresses your lenses directly, but on Sony cameras. Yes, that's one of my problems. Most reviews are on crop cameras, either M8 or Sony Nex. Boris Link to post Share on other sites More sharing options...

algrove Posted December 22, 2011 Share #22 Posted December 22, 2011 Sorry for the confusion. I'm not the OP and I'm not interested in shooting at wider apertures. I'm just looking for the best wide angle lens with a focal length wider than 18mm. As far as I know there exists only 3: ZM15, VC12 and VC15.From the examples I've seen both Voigtländers are clearly not as good as my Leica 18SEM (contrast, edge sharpness and colors). Therefore my question for the 15ZM, which I would probably only use from a tripod at f/8 or f/11, but sometimes at close distances (like at rock in the foreground and some beautiful landscape in the background). Boris You know I just reread the Sean Reid article again on ultra wides (he had the M8 at the time). An important point was made about the view blockage of the ZM15. Since he states that images are normally built from the bottom edge up. If this is the case no wonder the ZM15 was not the preferred of the 4 lenses he reviewed.

IkarusJohn Posted December 23, 2011 Share #23 Posted December 23, 2011 Boris, A couple of images, and crops, of our local Christmas tree - the Pohutakawa; these ones in the bay below our house. You can see that I did not shoot wide open, as it was too bright. At f/4 and f/5.6, the vignetting is not unpleasant. I hope this is helpful. In relation to focusing, the scale on the barrel goes from 0.3m, through small increments to 2 m, then to ∞ so focusing is not too dramatic, though it is easier with peaking on the NEX 5n. As to obscuring the viewfinder, this is not an issue on the M9, as you can't really use the viewfinder for anything other than checking shutter speed. I use the Leitz 21mm viewfinder for rough framing, and even that is still too narrow. Cheers John Welcome, dear visitor!

Bobu Posted December 23, 2011 Share #24 Posted December 23, 2011 Thanks John. In the review from Sean Reid the problem was not obscuring the internal viewfinder, but of an external 15mm Viewfinder. I would probably use the "Frankenfinder" with this lens, which should be ok for framing but probably still suffer from some view blockage. In your images I see some color shift in the lower left corner. I assume, that you have used neither lens profile coding nor cornerfix for PP.

jaapv Posted December 23, 2011 Share #25 Posted December 23, 2011 Thanks John! I have some experience with a 14mm lens on FF for landscapes (I used a Nikon 2.8/14-24mm lens on my Canon 5DII in the past). And the ND filter is also no problem for me, since I will use this lens only stopped down from a tripod.If you don't use corner fix, which lens profile setting do you use on the M9? Cheers Boris If you don't use cornerfix the LCC feature of C1 will allow you to correct your file with one mouseclick. Link to post Share on other sites More sharing options...

Boris Hi Boris, Coded as a 21/2.8 pre-ASPH, no corner fix. Actually, WB set as daylight in camera and 1/3 over exposure. No post processing or other adjustment at all.

IkarusJohn Posted December 23, 2011 Share #27 Posted December 23, 2011 Advertisement (gone after registration) In your images I see some color shift in the lower left corner. Hi Boris, I must be blind - I don't see the colour shit at all. In the first image, the road is littered with red flower threads from the tree. In the second, I see no red in the grass - colour shift would be red in the lower left, and green in the lower right. If I get the time, I'll take a picture of a white wall, wide open, and stopped down so you can see the worst of the vignetting and check for colour shift. I'd be surprised if its that significant. Anyone have a better suggestion for coding than 11134? Cheers John Link to post Share on other sites More sharing options...
Bobu Posted December 23, 2011 Share #28 Posted December 23, 2011 I think that I see some red shift in the lower left corner. I ask Zeiss which coding they would recommend for this lens. The answer was: 28 f/2.8 Asph. 11606 But they wrote, that they tested just one lens on one M9 and warned me, that there could be some variations between different cameras and lenses. The next best options according to Zeiss are 21 f/2.8 pre ASPH 11134, 21 f/2.8 ASPH 11135/11897 and WATE at 16mm 11626. Boris Link to post Share on other sites More sharing options...
jaapv Posted December 24, 2011 Share #29 Posted December 24, 2011 Did they test with new or old firmware? That makes a difference and I suspect the latter. Link to post Share on other sites More sharing options...
Bobu Posted December 24, 2011 Share #30 Posted December 24, 2011 Jaap, you are right. This is an important information. Zeiss has used the Firmware 1.62. But since the 1.7 versions are mostly fixing SD-card problems, the result should still be valid. Boris Link to post Share on other sites More sharing options...
