Guest guy_mancuso Posted April 12, 2007 Share #101 Posted April 12, 2007 Advertisement (gone after registration) Start calling they did say the end of April shipping from Leica but some have recieved them and some have been in stores. 39mm are out there and today being Wednesday i would guess a container may have come in maybe Friday or Monday we may see some in stores. I have a feeling my initial order for 4 free ones never got to Germany. I wonder who i can check with to see if they even got it Link to post Share on other sites More sharing options...
Advertisement Posted April 12, 2007 Posted April 12, 2007 Hi Guest guy_mancuso, Take a look here WATE filtered. I'm sure you'll find what you were looking for!
marknorton Posted April 12, 2007 Share #102 Posted April 12, 2007 Guy, it's interesting you're seeing different results from the B+W and Leica filters. I giess it stands to reason that with the cyan being most apparent with the widest lenses that the correction will be most closely matched to a particular filter for the 16mm. Let's hope there's little sample variation from filter to filter too. Link to post Share on other sites More sharing options...
DaveSee Posted April 12, 2007 Share #103 Posted April 12, 2007 here is a tease...Guy's lens with adapter and filter mounted. this is the first fully working prototype and is painted. Next week, black anodized versions, at least ten will be ready to ship. i will be responding to e-mails and other requests, e-mail is best. jm@milich.com this lens and adapter with filter is going to Guy for Monday. If I happen to need to see another lens for fitting tests next week...anyone in the NYC area? Wow! Great work... while not a maketeer, I'd suggest you name this, what... WOOZY? or FOOJ? or LOOM? I believe these "names" are not yet taken for Leica accessories, no? While not a contender to purchase this WATE add-on, I do admire the work to improve on the filter adapter. Kudos! rgds, Dave Link to post Share on other sites More sharing options...
gravastar Posted April 12, 2007 Share #104 Posted April 12, 2007 ........... What happnes is the B+W is overcorrecting too much and you still wind up with a little cyan cast in the 15 and 16mm. Without getting into the firmware mechnics all i can say is get the leica 49mm filter for the WATE and the leica 39mm filter for the CV 15mm. ................... There was talk about there being more than one manufacturing source for the Leica filters. If that's true I wonder if there is a difference between the filter performances, such as you're seeing, at extreme wide angles. Bob. Link to post Share on other sites More sharing options...
sean_reid Posted April 12, 2007 Share #105 Posted April 12, 2007 There was talk about there being more than one manufacturing source for the Leica filters. If that's true I wonder if there is a difference between the filter performances, such as you're seeing, at extreme wide angles. Bob. According to Leica (and confirmed with them several times), the shipping filters are supposed to be functionally identical to the 486 filters (marked Schneider MRC) that they sent me for testing. If there are differences seen, it will be interesting to know if they are consistent or the result of slight variations from example to example of a given filter.

From what I heard all the Leica filters are identical formula even from different companies that may have made them. Yes there are 4 from what i hear of the rumor Link to post Share on other sites More sharing options...
gerasdoc Posted April 12, 2007 Share #107 Posted April 12, 2007 Advertisement (gone after registration) Is there a possibility that the variation in color correction seen among the different focal lengths could be due to the M8 treating the WATE as a 18mm fixed focal length lens? Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted April 12, 2007 Share #108 Posted April 12, 2007 All I can say is the Wate is treated as a WATE,can't get into the specifics of the firmware for it Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted April 12, 2007 Share #109 Posted April 12, 2007 1.102 is released so now i can talk about it . Here is specific info for the WATE users WATE users Using the LEICA M8, firmware version 1.102 with the LEICA TRI-ELMAR-M 16-18-21mm f/4 ASPH. and a LEICA UV/IR filter About the lens The LEICA M8 has an increased sensitivity to infrared light. This manifests itself in a slightly purple rendering of dark or black surfaces (particularly black textiles). Using the LEICA UV/IR filter in front of the lens effectively prevents this from occurring. When using wide-angle lenses from 16 to 35mm with the LEICA UV/IR filter, a focal length specific correction of the color cast towards the edge of the image is required. With 6-bit coded lenses, this is done automatically in the camera as the lens type is transferred to the LEICA M8 as part of the coding. However, in the case of the LEICA TRI-ELMAR-M 16-18-21mm f/4 ASPH., the lens type transferred does not always correspond to the focal length actually set on the lens. Additional information is therefore required. When the LEICA M8 is being operated with the Firmware version 1.10 (or higher), the focal length specific correction is possible for this lens too. To do this, the Firmware version includes an extended menu: 1. Under the menu item „Lens detection“, select the sub-point “On + UV/IR” by pressing the SET button. A new monitor screen appears with the title „Lens detection Tri-Elmar + UV/IR”. Note: Provided “On + UV/IR” has previously been set, this monitor screen appears automatically as soon as the camera is turned on and/or the LEICA TRI-ELMAR 16-18-21mm f/4 ASPH is attached, regardless of whether or not the monitor was previously active. 2. In the box with a red border, the three focal lengths 16, 18, and 21mm can be selected using the direction buttons and/or the central adjusting dial and confirmed as normal with the SET button. Notes: • The setting in the menu must be made every time the focal length on the lens is changed. When the lens is attached, the middle focal length of 18mm is always preselected. • This manual adjustment of the focal length in the menu is only necessary with the LEICA TRI-ELMAR-M 16-18-21mm f/4 ASPH. The LEICA TRI-ELMAR-M 28-35-50mm f/4 ASPH. features the necessary mechanical transfer of the set focal length to the camera to display the appropriate bright-line frame in the viewfinder. The camera electronics detect the setting and use it to perform focal length specific correction __ Link to post Share on other sites More sharing options...
ho_co Posted April 12, 2007 Share #110 Posted April 12, 2007 Guy-- You say there are 4 manufacturers of the IR-cut filters, and that they are all *supposed* to do the same thing. But you discovered that the B+W 486 doesn't give the same result as the Leica filter. What if there's variation not merely from manufacturer to manufacturer but also from batch to batch from the same manufacturer? What if a given batch of E49 filters comes this month from one manufacturer, next month from another? And what if Mutti Leica has told us to use Leica branded filters, but they think that on the WATE that means E67, and we think it means E49? Did I understand correctly that the two pictures in this thread of the front of your house were actually shot with the B+W 486 and the Leica IR-cut, and not with and without the filter as you first said? Also, have you tried the Schneider/Leica comparison with the latest firmware? Might that correct some of the difference? It's really great how quickly Leica is moving on this, and how quickly we are getting the updates thru you! Thanks. --HC Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted April 12, 2007 Share #111 Posted April 12, 2007 The shots of the house are with the Leica filter one with settings off and one with settings on. On sample variation it is possible. the rest i am still not sure about Link to post Share on other sites More sharing options...

sean_reid Posted April 13, 2007 Share #113 Posted April 13, 2007 Guy and I were talking about this earlier today. The "official" word from Leica (when I spoke with them some time back for information to use in the "M8 Updates" article) was that the filters they would be shipping would be functionally the same as the B+W 486. The "official" test filters they sent me were marked "Schneider 486 MRC". When I tested, I found only minor differences between the two versions of the 486. It's possible that the formula has been changed a bit, that there is some variation among samples, etc. My sense of things right now is that whatever differences there may be might primarily be important for the two wider settings on the WATE. With 21 mm and longer lenses, the differences among filters (whatever they may be) may not be of much consequence in normal use. I'll be publishing an article in the near future with test chart results (cyan drift and vignetting) of the filters on various lenses, using an M8 firmware version that includes the cyan drift correction. The best I can do is to publish the information that Leica gives me "on the record" and update that information when possible. This is all a new process for Leica and its not inconceivable that filter plans, designs, etc. are evolving. The "white chart" tests will be instructive as well.

Guest guy_mancuso Posted April 13, 2007 Share #114 Posted April 13, 2007 Thanks Sean and well said. The only thing i can add since i was one of the first to have the WATE adapters was the B+W just did not correct well enough in the corners at the 16 and 18 the 21mm setting looked very good though. Than i replaced it with the leica filter and it cleaned up completely at 16 and 18 plus also the CV 15mm. So this is all i can go by is what i have seen and tested and i do recommend using the leica filters on these two lenses other than that it really made very little difference from 21mm up on what filter you used. Now there may have been some variance somewhere , but Sean and I both said these are very difficult filters to make with many coatings so the difference maybe even normal because of the extreme angles these lenses and filters are working at. Personally i am done testing this setup and Sean may give this a try and post some of his results in a upcoming article. but there could be variances in several area's and just not sure and all i can go by is my eye's and results. I'm not the engineer. LOL Link to post Share on other sites More sharing options...
marknorton Posted April 13, 2007 Share #115 Posted April 13, 2007 Received my two filter holders from John today, a very fine piece of work, thank you. My only suggestion would be to use a thinner o-ring; it's a little thick (1.5mm) to allow the hood to be tightened to the thread stop; replace it with the 1mm original from the front of the WATE and it tightens down very nicely to the thread stop ensuriing the hood is properly aligned. Guy, have you shown this to Stefan? Anyone want to buy a Leica filter holder? (You'd be mad to do so when this is available LOL). Link to post Share on other sites More sharing options...

Guest guy_mancuso Posted April 13, 2007 Share #120 Posted April 13, 2007 Might be nice to have a extra O ring around for future use if one breaks or something. Mark i have shown Stefan photos and images from it but not sent him one yet. Going to let John get caught up for users than maybe buy a extra one and send them my painted one, although that is a collectors item. LOL I have to say this is one of the best accessories i have seen. Again Mark and John a big thank you from me. Link to post Share on other sites More sharing options...
