wparsonsgisnet Posted June 19, 2007 Share #21 Posted June 19, 2007 Advertisement (gone after registration) After wrestling with a (red! wish I could have managed it) o-ring, I tried gaffers tape: see images. There are 2 single thicknesses of the tape that don't quite meet on either side of the filter holder. By twisting as I seat the filter, I have it touching the black portion of the lens itself -- quite a ways from the glass portion of the lens. Haven't put this on my M4 (6-classic currently living with my son in C--------a), but it works fine this way. Welcome, dear visitor!

DaveB Posted June 19, 2007 Share #23 Posted June 19, 2007 DaveB, Do you just set the CV15mm on infinity to focus with that filter? Do you have to do anything unusual when you meter? What film do you use or was this with the M8? Wow! I let the M8 calculate the exposure with the aperature set at 5.6 maybe. Manual white balance on the grass which I want to render white, but with DNG I suppose that doesn't matter. Because the CV15 doesn't have an IR focus mark, none of my Leica lenses do apparently, I've played around with trial and error and found best results with the infinity mark placed between the right hand 4.5 and 8 on the DOF scales. With this lens and filter, aperature of 4.5 -5.6 or so, ISO of 640 or 1250, plus a nice sunny day means you can shoot reasonably sharp IR handheld with the M8 with speeds ranging from 1/30 - 1/120 secs. I would very much like a filter holder that would get the filter down in there close to prevent vignetting and allow me to swap filters. As it is, I've affixed the filter with an ugly bunch of bandaids, rubber bands, etc. and have had it so for a couple weeks in anticipation of doing some IR's at my wilderness venue in Canada. I'm the last guy to complain about the IR sensitivity of the M8. The camera's sensitivity combined with the great DOF afforded by the CV15 makes a great combination for IR.

farnz Posted June 19, 2007 Share #24 Posted June 19, 2007 I use the CV15 and B&W 093 filter... Dave, Great IR shot! I've used a 46mm IR filter on my CV15 but ended up with heavy vignetting. Did you use the 37mm or the 40.5mm filter? Pete. Link to post Share on other sites More sharing options...
DaveB Posted June 20, 2007 Share #25 Posted June 20, 2007 Dave, Did you use the 37mm or the 40.5mm filter? Pete. This is the B+W 39mm 093 IR filter. It's the same filter I've used for M8 IR with the 35mm Summicron asph. It needs something like you see above to make it fit inside the hood. Any vignetting that results is because of the superwide angle rather than the filter impinging into the frame. Note Bill Parson's comment of how the filter fits all the way down into hood to rest on the black without touching the lens itself. Sandwich the CV15 lens between a couple jlm adapters on the front and back and you'll have a pretty versatile super wide for a reasonable price.
