finkaudio Posted April 17, 2007 Share #241 Posted April 17, 2007 Advertisement (gone after registration) The B&W 40.5MM should work fine if it has the same filter mount as the Minolta varient that I have. Hi, no, the 40mm got a 39mmx0.5mm thread- normally it's 39mmx0.7mm as far as I remember. I'm sure one can order a special filter for the 40mm from B&W.

Advertisement Posted April 17, 2007 Posted April 17, 2007 Hi finkaudio, Take a look here Leica stubborness will hurt sales. I'm sure you'll find what you were looking for!
JacquesBalthazar Posted April 17, 2007 Share #242 Posted April 17, 2007 If more lens options were available, that would increase the sale of M8 camera bodies (not that they are hurting). The coding system won't stop me from using non Leica lenses. I have a 50mm Hexanon that is doing just fine without the coding. I'll just live without the coding, and yes it does leave a bad feeling in my gut that Leica could show more appreciation for its customer base, and yet chooses not to. I think our loyalty to Leica is greater than theirs to us, and they seem to think they will make more money for the company by not allowing the manual lens profiling option. We live in a world of bottom lines driven by profits. Leica is no different. As I said, I'll still purchase non-Leica lenses, probably that CV15, or 21 or both, and not worry about coding. This is a sane attitude. Again the M8 + 3d party or Leitz M or SM lenses works fine uncoded and filterless EXCEPT in magenta drift situations (the infamous man made black fabric shots). So thank you Leica for that level of compatibility ! Furthermore, the magenta drift, when it occurs, can largely be corrected through existing profiles in post-processing. Thank you C1, Lightroom, Jamie and others for that. For those of us who need in-camera automated faultless magenta drift correction all the time (or on sensitive shoots, such as weddings for example), Leica proposes specific filters, its current range of coded lenses and a service for the coding of older M lenses. That works pretty well, even if in an ideal world we would certainly have preferred the issue not to exist at all. If you choose not to use Leica's coding service for your own Leitz/Leica lenses or not to buy current Leica lenses, you have to make an effort in post-processing, preferably on the easier to fix magenta correction front than on the complex filter+cyan correction front. Or do some DIY coding. I still fail to see why Leica should make an additional development investment for customers who precisely want to avoid investing in their current lens line or decline to use their coding service for older lenses. I know I have bought a 28mm 'cron rather than a CV precisely in order to enjoy ALL the M8 functionality at that focal length. If the menu had a feature allowing to key in lens data, permitting a similar level of perfected processing, I would most probably have purchased the CV alternative.... Nevertheless I think Leica should sell pre-coded SM to M adapters, at a price combining std cost for such adapters and a fee encapsulating the "coding service" (let us call it a license). Those adapters would officially cover the old Leitz SM focal lengths, but would of course be useable on third party SM lenses, in all cases without guaranteeing the level of individually customised correction allowed by the current firmware reference tables for recent M lenses.

waterlenz Posted April 17, 2007 Share #243 Posted April 17, 2007 I believe Zeiss/CV will introduce their own digital rangefinder sooner or later, as many have already pointed out, it makes no business sense for Leica to support third parties lenses, from the same perspective, it makes no sense for Zeiss and CV to support Leica's cameras either. LOL It is quite possible that they will introduce their own form of lens coding when they do. It could even be a chip, we shall have to wait and see. It is all hypothetical, however, whereas we now have a very nice M8, a bird in the hand.... Tom Link to post Share on other sites More sharing options...
waterlenz Posted April 17, 2007 Share #244 Posted April 17, 2007 Hi Tom, This pro would be happy to use a menu system for any lenses I have that are not coded. Remembering to set the correct code is like remembering to set the chosen ISO, shutter speed, aperture, focus, etc. Sean There is a world of difference between rotating aperture and focusing rings, shutter speed and ASA dials compared to working menus being an old boomer-greybeard.

waterlenz Posted April 17, 2007 Share #245 Posted April 17, 2007 I disagree and I'm a professional who uses the M8 for very fast-paced work. Cheers, Sean But pausing to re-program the camera every time you do a lens swap? Now if you have just one lens for each body, that might work. I recall you have more than one M8??? So if you could work with 2 or 3 bodies with the same number of lenses this could work. If that is your MO. Recall too there are multiple code choices for several Leica FL's. When I did my hand coding I had to look up the product number in my Leica library to figure out which one to use for my skinny Tele-Elmarit. Neither the lens code table and or this hypothetical menu would list the lens as the 'skinny Tele-Elmarit'; an example of another headache to this 'solution' IMHO. I guess one could carry a few Leica books with so that one could be assured of entering the correct code! Tom Link to post Share on other sites More sharing options...
waterlenz Posted April 17, 2007 Share #246 Posted April 17, 2007 On an individual basis, that's exactly what some are doing. Sean And should be continued!!! Link to post Share on other sites More sharing options...
waterlenz Posted April 17, 2007 Share #247 Posted April 17, 2007 Advertisement (gone after registration) I know, I own and use both . That wasn't what I was arguing against I said if R-D2 would ever exist and have newer sony sensor (D200) and remain open system there will be some point in buying it if one has many Leica and non-Leica lenses. even more so if Zeiss comes out with an open system body.. They would still have to solve the same issues Leica did by using the thin IR filter. Even a larger MP sensor while reatining the less desirable 1.5 crop factor might be more revealing in terms of image degradation at the corners. I recall that ZI wants to go 24x36mm; seemingly impossible with todays sensors, even with a thin IR filter; more corner territory to go cyan and then fix.

waterlenz Posted April 17, 2007 Share #248 Posted April 17, 2007 Many people have overlooked that as well. You make an important reminder. Cheers, Sean I am sure Leica has a good reason for not supporting those lenses, which I hope gets revealed. There must have been practicality reasons for some, the 64 limitation also comes to mind..... They should be congratulated for enabling using the most of the past in their M8 compared to the others including Canon, Nikon, and Hasselblad. Tried using an FD lens on your EOS? One can use a WW2 vintage Summar with LTM adapter as-is (no IR cut filter) for old lens effects, no one else can claim this from their old lenses.

waterlenz Posted April 17, 2007 Share #249 Posted April 17, 2007 Hi LJ, Some are now. I just published some this morning and will be regularly expanding the test base (lens/filter combinations). Cheers, Sean What is interesting is that you suggest the correction has been altered (Ultron not over-shot now). Maybe still more tweaking in future FW, the IR correction may be a moving target, implication is possibly problematic for 'non-supported' lenses.

waterlenz Posted April 17, 2007 Share #250 Posted April 17, 2007 Hi Jaap, Have you forgotten that Leica made thousands of screw mount lenses? Cheers, Sean \\ But there are only 64 codes! Tom Link to post Share on other sites More sharing options...
waterlenz Posted April 17, 2007 Share #251 Posted April 17, 2007 Hi Jaap, There are also old 35s and some people like having the EXIF data and potential vignetting correction for the longer lenses.

waterlenz Posted April 17, 2007 Share #252 Posted April 17, 2007 Add the 90 Thambar for that one, Sean. Could be used as-is. Has specialized filter too. Tom Link to post Share on other sites More sharing options...
waterlenz Posted April 17, 2007 Share #253 Posted April 17, 2007 Well, Sean, lets give Leica a chance to get their current stable of lenses in order. Cheers too Jaap Roger that one! Tom Link to post Share on other sites More sharing options...
waterlenz Posted April 17, 2007 Share #254 Posted April 17, 2007 It's not to hard to do and Stefan Daniel has already said that it is possible in a public FAQ document. It certainly can be done if they choose to do it and the beauty of it will be that people who don't like are quite free to ignore that line on the menu list. Cheers, Sean They may still do it too but by then many will have had their codable Leica lenses coded, so what would be the point? Tom Link to post Share on other sites More sharing options...
waterlenz Posted April 17, 2007 Share #255 Posted April 17, 2007 I was actually thinking about getting this lens for when i need a very wide with a extra stop of speed from the WATE I thought you HAD this lens, once. Tom Link to post Share on other sites More sharing options...

There must have been practicality reasons for some, the 64 limitation also comes to mind..... Not 64. The frameline switch is the 7th bit, with three values. So 192 possibilities.

waterlenz Posted April 17, 2007 Share #257 Posted April 17, 2007 Thank you, Sean, I'll look into this. I'm sorry, but I don't know a thing about older screw mount to M mount adaptors. What exactly are theses "no notches" adaptors? And aren't they getting very scarce? The notches are the long cut-outs, which I understand were for the focusing levers of the 50's vintage lenses. They are shown in virtually all Leica books and many are on Ebay at any one time. CV sells new ones. See the Gandy site. The long cut-outs have been copied though there is no real purpose for them today. The short notches and ends of the long cut-outs interact with nubs on the old rear caps, act as a 3-point spanner wrench for removing the adapter off an M body. A few were made with no long cut-out, just 3 notches, these are what is needed for adapting LTM lenses with coding on the M8 Tom Link to post Share on other sites More sharing options...

I do not see any here: Leica M8 Lens CodesTom Not (yet) but the possibility is there.The WATE btw uses one position and the TE three, so it even accommodates 190 different lenses. That should take us into the next century. Link to post Share on other sites More sharing options...
lct Posted April 17, 2007 Share #260 Posted April 17, 2007 ...Neither the lens code table and or this hypothetical menu would list the lens as the 'skinny Tele-Elmarit'; an example of another headache to this 'solution' IMHO. I guess one could carry a few Leica books with so that one could be assured of entering the correct code!... Not a tele problem of course. Just Leica and other wides that cannot be coded so far. We don't use dozen of such wides obviously. We don't need special settings either. Just default settings for each Leica focal length i.e. 16, 18, 21, 24, 28 and 35mm. This way i could use the '35' setting for my Summaron 35/2.8 or my Summicron 40/2 if need be. Also i may be a somewhat great Leica user with 5 Leica bodies and 19 or 20 Leica lenses but i like much my cute M-Rokkor 28/2.8 as well and i would like to get a little 21mm lens like the Zeiss 21/4.5. I could then use the '28' and '21' default setting and everybody would be happy. Also the question is not to know if it will be easy to use the menu or not or if the results will be perfect or not. The problem is to know if Leica users are allowed to use their M or LTM lenses without ugly color casts on their Leica body. A negative response would be a disrespect towards old and new Leicaphiles IMHO. Link to post Share on other sites More sharing options...
