marknorton Posted January 30, 2007 Share #21 Â Posted January 30, 2007 Advertisement (gone after registration) The code on the lens just says "16-18-21 Tri-Elmar" and there's no coupling with the camera to tell it the selected focal length and therefore what correction to apply. One approach could be to add an extra entry to the SET menu on the fly when the camera recognises the WATE mounted, it would have 3 entries so that when you select the focal length, you set the finder and the menu to match. Can't see any other way of doing it. Â Keep in mind we know there is no focal length in tghe EXIF header when this lens is used, confirming the camera just doesn't know.

tom0511 Posted January 30, 2007 Share #22 Â Posted January 30, 2007 maybe 1.10 can analyse the level of cyan-contamination in the image and use it to identiify if 16-18 or 21 has been used Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted January 30, 2007 Share #23 Â Posted January 30, 2007 I was sort of thinking the same thing. Sort of like it see's the image determines the focal length by maybe the distortion factor than in the firmware it adds the correct amount all this through the processing engine. Okay that was a wild hair but maybe something like that. There must be a way that the sensor can detect the WATE and the focal length used Link to post Share on other sites More sharing options...

Can't see any other way of doing it. Â Mark - This thread is getting gloomier than I expected when I began it. For my kind of photography rangefinder cameras are about being close and wide, and utilising the lens quality advantages available for rangefinder lens design. My choice of widest angle lens to use on my M8 is crucial for the camera's commercial usability, and as a customer I am embarrassed on Leica's behalf that a properly functioning wide angle lens of at least 24mm EFOV [ie 18mm] was not available to launch with the M8. Â If one has to menu tweak in the manner you speculate, then for me it negates much of the efficiency of having three focal lengths in one lens. Rather than that working method I mostly would prefer a less expensive fixed focal length wide and gamble on being able to adjust 'focal length' by taking steps forward or backwards. It seems an odd design decision to go with the WATE, and given it's formidable price, workarounds are inexcusable. After all, this is Leica we are buying into and whilst I cannot speak for anyone else; I expect better. Â ......................Chris Link to post Share on other sites More sharing options...
osera Posted January 30, 2007 Share #25 Â Posted January 30, 2007 FWIW, I think that the WATE is becoming one of my favorite lenses. I am using it for landscape type work, and have (conveniently) ignored the IR issues for now. They are there, no doubt, but they have not been an issue yet. I have not come to grips yet with what will be needed when I try it with a filter.

marknorton Posted January 30, 2007 Share #26 Â Posted January 30, 2007 Interesting review and it looks to be a fine lens. Just a pity that Leica did not, as MR say, "sweat the details". Link to post Share on other sites More sharing options...
jrc Posted January 30, 2007 Share #27 Â Posted January 30, 2007 Advertisement (gone after registration) They'll have to put some kind of menu selection in, sooner or later; I would hope in 1.10. The lens coding (it has lens coding, right?) could be used to automatically pop up the focal length selection on the set menu, and then it wouldn't be any more trouble than selecting ISO, which has turned out to be not that big of a deal, for me, at least. Â If they do put in a lens menu, it'd be nice if it would have a secondary menu that would include all lenses, so people would have the option of not coding their lenses, or using non-Leica lenses by slecting the coding independently of the lens itself... Â I love my M8, but this IR problem has turned ugly. Originally, I didn't pay too much attention to it, because the fix was easy enough with filters, and I always used filters anyway. The banding and green blobs, etc., seemed like a bigger issue. But those are simply fixed. The IR turns out to have all kinds of subtle ramifications. It has been claimed, though I don't know whether it's true or not, not being an engineer, that the problem could have been avoided simply by choosing a different (not thicker) IR filter glass for the sensor...Maybe that's the solution for the future.

ChrisC Posted January 31, 2007 Author Share #28 Â Posted January 31, 2007 I have just re-read the WATE review by Michael Reichmann and it is encouraging. However, given the the flack aimed at him by those who felt he downplayed the IR issues when he reviewed the M8, I'm surprised there is no mention of the filter/hood/cyan drift concerns about the lens as discussed in this thread. M.R. will surely know of these lens issues, I find it curious as to why they did not merit some comment. Odd. Â ............Chris Link to post Share on other sites More sharing options...
Michael Reichmann Posted January 31, 2007 Share #29 Â Posted January 31, 2007 I do not have an appropropriately sized filter, or the required hood / filter holder. When I do, I will test these areas of concern and report on them. Â Michael Link to post Share on other sites More sharing options...
marknorton Posted January 31, 2007 Share #30 Â Posted January 31, 2007 The filter holder, as shown on Erwin's site is nothing more than a step-up ring from the unusual thread on the front of the lens to E67. There's no hood element to it at all and I don't think it's acceptable to have to remove the filter holder and replace it with the standard hood/lens cap just to protect the lens. What do you then do with the filter to protect it if the filters are as susceptible to scratching as is said? Â There is an E67 lens cap from R-land but the bottom line is that Leica do not supply you with the filter carrier, filter, lens hood and lens cap you need but do supply you with lens hood and cap which you can't use. Â Overall, the lens is very badly thought out to handle to IR issue and using it is going to be a juggling act of dials, menus, filters, lens hoods, lens caps...

I didn't see any mention of this in the review article and would be interested to know how it compares with the Zeiss 15mm in this respect. I have little need for an extreme wide angle for reportage type work (where lens distortion is less of an issue) but do the odd bit of architectural stuff (especially interiors) where distortion becomes a major issue to me (I am generally not keen on correcting it in post).

bradhusick Posted January 31, 2007 Share #32  Posted January 31, 2007 For your amusement, here is a shot on the WATE at 16mm, ISO 640, 1/125sec. The first is oversaturated by design to highlight the different colors of the sunglasses. The second is a B&W that I also like. No additional distortion correction was applied. No filters were used.  -Brad Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!
