CV 12 and 15 -- and adapters, please

The M8 has such detail in its image files that I am preparing to acquire a w-i-d-e lens. I have 24, 35, 50 75 and 90, and am thinking I might stretch to the CV 12 (a 16mm, effectively).

 

There was a post which indicated the proper ltm adapter to get for the 15, but I don't recall seeing the adapter for the 12,

 

Would users indicate the proper adapter for each lens, please?

 

tnx.

However, if you should want to hand-code it to get the vignetting correction of a 21mm lens (which is probably the right place to start) you should buy an adapter which brings up the 28mm frame lines. That way it looks as much as possible like a Leica 21. The rumors that Leica will make it possible to set an "equivalent" lens characterization in the coming firmware are starting up again, so maybe this won't matter in the long run.

Bill - go with the WATE - new Tri Elmar. At least you can focus with it. I know the 15 is uncoupled not sure about the 12. i got my WATE on order from Sohms - someone said their ordering staff got the flu last week...;)

Charles, neither the 12mm or the 15mm are rangefinder coupled. Though DOF is enormous and I've never had a problem focussing the 15mm - I don't have the wider lens.

 

I'm sure the Tri-Elmar is an excellent lens, but with the viewfinder it's about 5 times the cost of the 12mm + viewfinder and 10 times the cost of the 15mm + its viewfinder. It really depends on how much Bill intends to use that particular focal length - and how much he's willing to spend of course :-)

Bill:

 

You want the Leitz 90mm adapter. The other adapters have a cutout where the coding needs to be. The WATE brings up the 90mm framelines, so that would also be the adapter you would need to have the 12mm or 15mm emulate the WATE.

 

There has been speculation that with a WATE mounted the newer firmware will prompt you to select which focal length the lens is set at. This may also allow you to pick the 16mm,18mm, or 21mm to see which vignette correction works best with your 12mm or 15mm.

Thanks, Robert.

 

I searched the forum and found the reference to the 9cm adapter for the 15mm CV.

 

I plan to use this for outdoor landscapes, primarily, so focus clearly doesn't matter. There was a post here in the last few days about this lens (or the 12mm) and out-of-focus images. The person who answered recommended using infinity and not hyperfocal distance to get a good focus.

 

I like the price of the 15 more than that of the 12. I'll acquire an adapter as my first task.

 

Do I assume that the 9cm adapter can be hand-coded for the 15?

 

My real problem is that the lenses are *slow* so they won't be much use for available light photog. My 24 is only 2.8 and that makes me unhappy.

 

Leica -- give us a fast, wide lens! Everyone wants one of these. I'd settle for a 21mm f1.4 asph and hang the cost.

 

Thanks to all.

The 9cm adapter can be coded very easily. Since it is just a metal ring, I used a drill press and made the six indentations using a bit. I was worried the brass would tarnish and not be bright enough to show up in the code, so I filled the indentations with white and black paint. A 21mm is the suggested code for the 15mm, but I would wait for the 1.1 firmware in hope it has the WATE functionality and then code as a WATE.

Bill-

I used a 12mm on my R-D1 because Sean's review showed that it vignetted much less than the 15....and got good results. I sold it and ordered the WATE (on my 30% discount deal), though....but Solms just told me that the WATE will come in about 2 months...I just think that f4 is better than the others, and Leica will provide much better correction for Leica lenses.....plus, when going that wide, I like to use the least wide lens I can for the situation, due to the distortion that the superwides introduce...

That's a few stops faster than my Pinhole "MagnæLux" 21mm f120

 

Is there a way to check if I have a ASPH "MagnæLux" :rolleyes:

Bill, you should try to find an old original Leitz 90 mm adapter, if you want it to be codable. All the C/V adapters have that irksome cutout where the coding should be.

 

The WATE and its finder is a monstruous piece of apparatus. Apart from the bulk and weight, the chances of putting your foot into it by accidentally mismatching focal length and finder setting are nearly infinite. It is a most un-Leicalike contraption.

 

The 15 mm is a jewel, d.o.f. is so great that you can mostly treat is as fix-focus -- set it at 2 m indoors and 4 m outside. Pictures look good even wide open. It is close to immoral not to buy it.

 

That said I still hope that Kobayashi-San at Cosina will give us a version with an integral M mount (self-codable!) and a front filter adapter. Maybe even two, one for the FF M and one for the digital one. Still, it is quite possible that the lens would not vignette with 55 mm filters even on the full format. A faster lens would maybe do that -- but do we really need one?

CV15mm @f5.6 on M8, ISO 320 - Irish brewpub in London yesterday

Sure - no correction for vignetting. Opened in CS3 Bridge and adjusted for exposure (obviously the skylights were far brighter than the interior) and then tweaked levels and colour in PS. A touch of sharpening. Tripod was my table :-) Excellent stout, BTW! 0.7 sec @ f5.6 Colour balance was Daylight. Tried one at Tungsten but it was not as nice to work from.

I have one too; never found the inherent lack of speed a huge problem for the shots I want to take with this.

 

It's a great lens, and for the money can't be beat.

 

If you order from CameraQuest, and tell Stephen you have an M8, he'll ship the 21mm vf with the lens instead of the 15, which is nice.

 

I also haven't even tried to code this lens, so the CameraQuest adapter is fine as well, but then I'm not using it with a filter either.

Hi Jamie,

Just FYI, he stopped exchanging viewfinders a few weeks ago -he said he had an abundance of 15mm finders to get rid of. At least that's what he told me when I bought one. :)

 

Take care,

I shot a sodier's funeral yesterday for my newspaper using the CV15 (and other lenses), on my M8. i have always been quite pleased with the scale-focusing results. although there is a degree of vignetting, it is correctable in camera raw. i do wish it was faster than 4.5, but that's about it. it's a fantastic little lens. I suspect the 12mm is equally good. both shots were @ f5.6

 

incidentally, the pic of the patriot guard dude has the sky going darker on the right, but that had more to do with morning sun being to the left of the subject than vignetting, although there was some.

Are you sure it is not Alzheimers? Having failed to code my Elmarit-M 90 in anything like the time-scales they quoted (14 days quoted, not even entered after 12 days and a further up to 6 weeks now being added to coding period), they now can't be bothered to send it back to me. Still not dispatched from Solms in spite of lens coding being cancelled and lens return requested by German Dealer last Wednesday - it sucks. The German dealer is embarrassed.
