    Leica New Leica M-E (Typ 240)

    I've never had a problem focusing my Canon 50/0.95 on the Canon 7. No special shimming required, just worked when bought over 15 years ago. For M-Mount, no problem with the Nokton 50/1.1 and 7Artisans 50/1.1. I use Liveview on my Nikon DF when holding it up high to shoot over a fence, such as...

    Leica Showcase Industar 61L/D in Leica Mount

    I'd call that good enough. I set the shim so that close-in focus is slightly behind the RF, but covered by DOF. That way Infinity focus should be good.

    Leica New Leica M-E (Typ 240)

    The M-E 240 looks like a "stripped down" version of the Leica M Model 240, similar to the original M-E being an M9 without a few features. The Zenit-M uses the same sensor, may have many components in common, but looks like a new body. The body, at least to me, bears some resemblance to a...

    Leica Showcase Industar 61L/D in Leica Mount

    Add the second shim, then tighten the retaining ring down. Paper has some compression to it- two paper shims, tightened down, should do the trick.

    Leica The pleasures of body maintenance

    Tree Sap: Yuch! Q-Tips, a Million and One uses! With Sensor Cleaning: I learned that you need to settle for "close-Enough", usually accomplished after using a blower and wet-cleaning twice. After that, only need to do after a year or two. I also learned to keep the lens mounts very clean...

    Decompressing after a shoot

    Hot Tub, New Order, Fireball. That should work for most people. Maybe not "New Order", substitute favorite music. But not decompressing from Photography, that is part of my decompression. More like decompressing from a day of work that meetings get in the way of writing code. Somedays- after...

    Leica Showcase Industar 61L/D in Leica Mount

    For cameras with a removable back, hinged back, or flap: I've used a clear negative strip, taped to the back of the film gate with. Then use a loupe with a glass reticle to hold it flat while viewing. For the Barnack style cameras: you just have to test with film.

    Leica Showcase Industar 61L/D in Leica Mount

    Did you test the lens as delivered? Was it back-focusing then? If it was back-focusing originally, 1 paper shim should not throw it off unless something is holding the lens out of place. Sometimes you get lucky with a lens, it is right on. Sometimes- someone else has adjusted it.

    Leica Showcase Industar 61L/D in Leica Mount

    I paper shim, maybe two- are all that is "typically" required. This is where shooting a test is the final authority. The worst I-61 I've seen was off my 2m at a 5m distance.

    Leica Showcase Industar 61L/D in Leica Mount

    I have not done a guide for the I-61L/D here, or Leicaplace. Probably done long ago on a now defunct website. This is not too bad: The rear light baffle will pop out, I use pliers designed for split retaining rings, the type that needs to be spread. After that, a standard spanner is use to...

    Nikon Dropped my Df

    I dropped a Nikon F Photomic Tn once. Put a gouge in the table that it dropped on. Did nothing to the camera. I would never use a Nikon F to drive nails, but it is reputed to work well as a hammer.

    That's the best thing to do- they can also give the camera an alignment test and look for any hidden damage.

    [Image comparison] 12 years old camera kills, seeing is believing

    In the Leica world- many stand with the Leica M9 as being the camera that has given them their best images. Some state the M8 gives the "most crisp" image. Manufacturers do not release technical data as they used to ten and more years ago. Looking at the images: the spectral response of the...

    Leica Showcase Zeiss 50mm 1.5 C-Sonnar

    I've done a lot of push-processing in post for the M8 in RAW mode. As much as 6-stops. Leica - Leica M8- set to ISO Ludicrous Speed... I use the slow 4x card in it. A newer high-speed card can cause uneven power-draw as it buffers and writes, waits for the buffer to fill. The card being...

    Leica Showcase Zeiss 50mm 1.5 C-Sonnar

    Ray- there is quite a bit of banding in your M9 shot, this is an issue that can be caused by the battery being on the weak side, or by the specific SD card used in the camera. It is often magnified when using DNG-8 (compressed) mode. I had this issue in some of my M Monochrom shots when using a...

    Leica New Leica M-E (Typ 240)

    The M8 does much better using RAW mode (button Dance), shooting at 160ISO with exposure compensation used to "boost" the speed. Post-Processing to bring the intensity up. The chroma noise in M8 high-ISO images is a side-effect of the compressed DNG format, which creates chaotic contours in the...

    I'd rather carry a couple of fast fixed-lenses rather than a comparatively HUGE fast-zoom. For video- it makes sense for a super-speed zoom. I used to shoot a lot of movies long ago.

    Infrared Images Infrared portraiture

    From 2006 or so. in the 70's Pop Photo published an article "UnEarthly Infrared" in which the photographer use gelatin filters to achieve some interesting results with IR Ektachrome. IR film is "full spectrum", must be used with filters to block the unwanted portions of the spectrum. Much like a...

    Leica Broken filter ring on J3

    We'll call this the incredible Jupiter-3 Glass Transplant... The 1962 and 1961 J-3 were quite close, some slight differences. But close enough to transplant the front element, rear triplet, aperture ring, stand-off ring into the good barrel. Used a fairly thick 1.6mm shim, and re-indexed the...

    I have not bought a new digital camera since 2013, with the Nikon Df. Digital Leica M- 2012 for the M Monochrom. Most of my money goes to vintage lenses, and that has slowed down. The cameras have depreciated, the lenses- have gone up in price. Somehow I collected 8 Contax RF's, 2 Contax II, 2...

    My u43 with the 17/2.8 gets quite a bit of use. Small, and I keep the flash on it. The Leicas get the most use. It is easy to go overboard... Go slow on getting new lenses. There are a lot of less expensive choices on the used market. A Voigtlander 75/2.5 is small, light, and sharp. Buying...

    Infrared Images Visible+Infrared with the Leica M8.

    Red filter- blue/red channels swapped. The Red filter eliminates green and blue. The IR sensitivity of the Blue and Green picks up at different wavelengths. Experimenting, I got best result with the Orange filter.

    Infrared Images Visible+Infrared with the Leica M8.

    The Leica M8 has a relatively week IR absorbing filter with a 5% leakage in the IR. An Orange filter blocks Blue light and about 1/2 of Green light. These are shot using RAW mode to get uncompressed DNG files, then the Blue and Green channels are equalized with Red. The result is IR in the Blue...

    The higher-end Kolari conversion filters -- worth it?

    I can't answer your question directly- I've always had full-spectrum conversions done and used external filters. The first one cost an extra $4,000 to have made as full-spectrum over the camera's base cost of $8400. So "$150" seems cheap. Do you have the standard 590nm filter now, or the coated...

    Leica Showcase Industar-50 Collapsible Mount 50mm F3.5

    The Sun made a brief appearance early this morning- was overcast yesterday. Some airplanes in blue sky- infinity test. Close-up to infinity focus is good across range. Shot of open sky past treeline, this lens is resistant to flare. Some slight vignetting at corners: I need to check if the...

    Leica Showcase Industar-50 Collapsible Mount 50mm F3.5

    I learned to tighten the barrel in the mount "all the way". Like the Elmar, it is held by friction. This lens has more contrast than the Industar-22 and Industar-26 (50/2.8). The use of Brass and machining of the collapsible mount is better than the I-61L/D. I suspect the I-50 and I-61L/D use...

    This lens is easy to work on, remove the stop screw to separate the helical. Be prepared with Lighter Fluid, Alcohol, Q-Tips, paper towels, and a fine-point screwdriver to get the old grease out. I use a heavy lubricant, you can fine similar heavy grease in the plumbing department of a hardware...

    Leica Showcase Industar-50 Collapsible Mount 50mm F3.5

    This lens is a Tessar formula 50/3.5 in a brass mount with "very shiny Chrome". Performance compares well with the post-war 50/3.5 coated Elmar and coated Zeiss Tessar 5cm F3.5. The I-50 is the third formulation of the 50/3.5 Tessar in the Industar series, it improves on the optics of the...

    Leica Broken filter ring on J3

    That gives a good idea of how far off the focus is. As you have the full-res images, how many centimeters do you judge the back-focus to be? I have a formula for converting back-focus to increase the thickness of the shim. Getting the value for your camera is critical.

    Leica 50mm woes

    I made an Astigmar 50/2. I used the front section of a 5cm f2 Sonnar with the back section of a 5cm f2 Retina-Xenon mounted into an I-61 focus mount, RF coupled. It was wild. I gave it away to a friend.

    Leica Trying to adjust a Jupiter 8 for Leica

    Sample variation exists, and I only suggest doing this for lenses that are first shimmed for close-up/wide-open work but do not give an acceptable focus at infinity when closed down 1-stop or so. This condition indicates the focal length of the lens is on the long side of the range. The...

    Leica 50mm woes

    Long focus throw- think of it as having a long rangefinder baselength. The movement from 3ft to infinity is just a few millimeters from the image plane. A long focus throw is more precise when focusing a fast lens. I wish the 50/1.1 Nokton and 50/1.1 7Artisans had 180degree throws.

    Stuff on sensor that simply will not come off

    Dust and "Gunk" would have come off, or at least changed position with the cleaning that you have done. I would suggest looking at images before and after the cleaning. If the artifacts do not change size, shape, or position- the damage may be in the glass. Leica users know this all too well...

    These are "Triple-Zero" screws. I use a hand drill with a triple-zero drill bit to get them out. Sometimes you can use the tip of a flat head screwdriver and nudge it out.
