Continually Impressed with the CV 15


Recommended Posts

These shots were taken at a wild mustang auction Friday. Prison inmates work with the wild mustangs, which are auctioned anually.

 

It gave me a chance to put the CV 15 through it's paces. No self-coding, no filter, almost all shot at f8. This is one sweet little lens. (I used the 'lens correction' in PSII camera raw to fiddle with vignetting.)

Yup. It's a pure "no-brainer" lens. Just today I finally succeeded in hand coding the lens to "look" like a WATE lens on my M8 with current firmware!

 

I took this photo of a Byzantine music concert last month in a local church, chosen not for its obvious beauty, but for its wonderful acoustics (and very friendly staff!). CV15 lens; ISO 320; non-coded lens with B+W 486 filter affixed with an O-ring from my loca hardware store.

Very nice!

 

Man, if you didn't use a tripod, you sure know how to keep your vertical lines plumb. Especially hand-holding for four seconds.

 

The CV15 is a challenge indoors; outdoors it really is a no-brainer, even wide open. I'd love to try out the CV12, but it's so stinkin' slooooowww! Seems like most of what I shoot on assignments in in low light.

I thought the lack of rangefinder coupling would bug me, but the depth of field with such a wide lens brings sharp focus right up to the foreground.

 

I don't feel the lack of a viewfinder is a problem either. I'm framing shots just fine.

 

Holding an IR filter in front of the 15mm CV I can pretend I'm William Henry Fox Talbot.

how are people finding the exposures with the CV 15mm on AE on the M8?

 

i'm finding i constantly have to compensate +2/3 otherwise the CV15mm will underexpose.

 

im not having that experience but i do exposure lock on the "hottest" part of the frame...B

It underexposes for me as well. I find myself adding 2/3 -1.5 EV with this lens. The histograms for all my M lens seem skewed left, but it's most apparent with this lens. Less so with the 28mm CV, slightly with the 35mm/2.0 and not at all with the long lenses.

 

Is it characteristic of the M8 that it systematically tends to underexpose with wide angle lenses? That's not been my experience with other film cameras.

 

The spot metering area is pretty narrow with the M8 and that, it seems to me, would result in more variability in metering using wide lenses.

My first photos with a cv15. My favorite barn near my place. Shot through the window of my car during a storm.

 

ISO 160, f8, 1/60s, no filter, JPEG Fine, Medium/High contrast.

 

It tends to underexpose by almost 1.5EV. Adjusted the level in PS.

 

Love this lens!!

 

PS: How the heck can I post photos directly in the post??

Did you code the CV 15 lens by hand on the cameraquest LTM to M mount adapter or the John Militch adapter? If it was the cameraquest please let me know how you did it.

 

thanks, Jim

Yes.... a sweet lens for sure... it exceeded my expectations.

All un-filtered, uncoded.....

Exposure problems arise out in the open if the sky is overcast or hazy, and thus much brighter than the ground. With a blue sky, the lens takes in so much that most anomalies even out.

 

I do recommend the bayonet and filter adapters made by John Milich (jm@milich.com). I have coded mine as a WATE and this works OK – though I wish Leica had made up a 16mm single coding, so I could get rid of that menu! In the front adapter I use a B+W 486 filter. Result: No brightness fall-off, no noticeable cyan vignetting. Have not tried my 72 IR filter yet, but it works fine on my old 35mm Summicron.
