wparsonsgisnet Posted January 20, 2010 Share #6 Posted January 20, 2010 This particular lens will not have changed the laws of optics and light refraction, unfortunately. Imagine how many they could then sell?! Of course you have sw to deal with this: cornerfix or a series of PS actions. Who said you had the right to use a wide angle lens??? This produces a viewpoint that you cannot "see." Talk about your alien images. lol Link to post Share on other sites More sharing options...

Walt Calahan Posted January 20, 2010 Share #8 Posted January 20, 2010 I own the original 12 mm, now if anyone wants to send me their M9 I'll gladly test the original version of this lens as it works on the M9. Grin. The original 12 mm is not rangefinder coupled. There is no need because the depth of field at f/5.6 covers the majority of our working focus zone. The original 12 mm heavily vignettes, so don't expect the updated version to be much better. A centering filter should be used with this focal length, but I never got one.

Alnitak Posted January 20, 2010 Share #9 Posted January 20, 2010 The original is very good on the M9. It actually has less of a "red edge" issue than the 15mm, and if you manually set it to the 21/2.8 11134 the vignetting is pretty nicely corrected. Here's a couple of shots with this lens on my M9 from this past weekend in London: You can just barely see a bit of red in the sky on the left in the first image. I didn't bother correcting it, but Cornerfix does a very good job. As for the new lens, it looks like a nice improvement in a few areas, but I wonder if the optical formula is changed. The current hood is lousy, and can spin to where it cuts into the image; I like the looks of the new built-in hood. The new finder looks more compact as well. I will no doubt pick one up and do some comparisons with my old model. Jeff Link to post Share on other sites More sharing options...

Moritz Posted January 20, 2010 Share #11 Posted January 20, 2010 Hello Jeff, the second picture is really excellent. The first, thus being technically perfect, does show me not to use 12mm in this matter with all this torsion of buildings.

A centering filter should be used with this focal length, but I never got one." Walter: please excuse my ignorance, but what is a "centering filter"? I had the LTM version of this lens, used it on a M8 with Milich adapter for the UV/IR filter, and was never quite happy with it, mostly because of pretty bad vignetting. If it vignetted on the M8, it would have to be much worse on the M9, I thought, so I sold it. Now maybe I will rethink 12mm. The 4mm between this lens and the 16mm on a WATE is actually a huge difference. Link to post Share on other sites More sharing options...

The first, thus being technically perfect, does show me not to use 12mm in this matter with all this torsion of buildings. Best Regards Moritz Yes, even though the lens is very well-corrected, its not designed for architectural shooting. The WATE has the same issues at 16mm. In reality, if you want distortion-free shooting of this type, about your only real choice is the Canon platform with the 17mm TS-E lens. Personally, I don't mind the distortion, but I know everyone's taste varies. Jeff Link to post Share on other sites More sharing options...
Rick Posted January 20, 2010 Share #14 Posted January 20, 2010 The WATE has the same issues at 16mm. Jeff It does? I have come to realize that the WATE and Frankenfinder seem to be the Rodney Dangerfield of Leica products. I'm going to start referring to them as Rodney and Victor from now on.

I'm going to start referring to them as Rodney and Victor from now on. Yes, I love the WATE, but the distortion is the same. Actually, it's pretty normal for this type of lens; I don't know of a 16mm or 12mm that has less distortion. A lot of the problem with buildings like this is also perspective. If I could be a platform such that I was at mid-level of St. Paul's, the distortion would be dramatically reduced.

Alnitak Posted January 20, 2010 Share #17 Posted January 20, 2010 While I'm at it, another shot with the CV 12mm and M9 combo. Again, you can see the little bit of red edge on the left. I will correct that later in a final version, but this is one I loaded up while I was in my hotel in London. Some shots just require a super-wide lens.

adan Posted January 20, 2010 Share #19 Posted January 20, 2010 'Way back when the Epson R-D1 was the only digital RF, Sean Reid noted that the 12mm had better edge performance than the 15mm (but the 15 was a tad sharper in the middle). That appears to bear out on the M9 - most of the examples I've seen from the 12mm have less red-edge probalems than those from my 15mm. I could crop "15mm" images out of these 12mm samples and lose the red edge altogether. Link to post Share on other sites More sharing options...
Moritz Posted January 21, 2010 Share #20 Posted January 21, 2010 Again Jeff, the indoor shot of the museum is terrific. It seems to me this lens should be used only indoors the way you take them. Best Regards, Moritz Link to post Share on other sites More sharing options...
