Here's picture of a pineapple.

SL2 with the 7Artisans close-focus M to L adapter.

https://7artisans.stor​e …rs?variant=3941​1793494224 (external link)

The adapter is a dumb adapter, but includes a helicoid for additional focus so that the typical close focus distance of an M lens (about 0.7m) can be reduced even further, to about 18 inches or so.

This shot was with the Noctilux 50 f/1.0, refocused with the adapter at about 24 inches or so (the shot is slightly cropped here to a 4x5 aspect ratio).

The build quality is good, no slop in the connection or the engagement of the adapter to the camera or the lens. Adds extra versatility to adapted M lenses on the L mount and costs A LOT less ($69 USD) than the Leica M to L adapter ($450 USD). You just need to enter the lens data manually in the SL2 menu for M lenses, presumably for IBIS to work properly. Non-Leica adapters will not result in EXIF to be written for lens info, even if you choose the lens from the camera menu. Booo.

M8 at 40mm one wide open one stopped down a bit. Pretty great for a 15 year old camera.

Do the viewfinders improve on the M cameras? My only complaint on the M8 is that it is hard to focus sometimes because it’s hard to tell if I have perfect focus. It seems a bit dark/muddy. And I do keep a lens cloth with me to clean the windows.

Yes the M 10s viewfinder is a lot better. But it does take some practice. gove it time you will get good at it. Also learn to use the DoF scales on the lens. I usually just use my shirt for the viewfinder.

A follow up on the pineapple image - here is a comparison of the close working distance (measured from the front of the lens to Dwight's forehead) for various M mount lenses on the SL2. I chose the scene to render the foreground-background "compression," the effect of bokeh on the close focus distance, and the scale of the foreground and background objects and perspective distortion. I rendered all of the images from raw captures in Capture One, with some slight tonal adjustments to equalize the images visually. White balance was set from the Color Checker upper rows for white balance.

In all shots, I used the 7Artisans close focus M adapter. The tripod height was set so that the center of the field of view was aligned with the center of Dwight's face. In the wider shots, the adapter is dialed all the way to no focus adjustment; in the tighter shots, the adapter has been dialed all the way to maximum close focus. In all cases, the lens barrel is focused at the closest distance focus stop. Aperture was set to the widest aperture on the lens.

To focus the camera I set the above parameters and then moved the tripod until focus was on the bridge of Dwight's glasses. I measured the working distance with a laser rangefinder and rounded to the nearest half inch ... except for the 15mm at close focus - the lens was an inch from Dwight's forehead.

Interesting and versatile adapter.

Kirk

EDIT - added graph ... because, engineer. Think of the percent change as a percentage of the original close working distance the adapter gets you closer to the subject. 0% - closes no distance to the subject (your close working distance is no closer than the lens' inherent close working distance). 100% - closes all of the distance to the subject (the adapter permits you to focus with the front of the lens touching the subject at the plane of focus).

For macro work i would highly recommend one of these. You can get them pretty cheap and there is absolutely nothing better.

forum: Leica Cameras

A couple of years ago, I contacted John Kreidler, a Leica US tech support guru who is, coincidentally, based in the Philadelphia area, about the SL2 not transferring EXIF lens data to files that have been shot with Leica lenses adapted with non-Leica adapters - i.e., affordable ones. LOL. Well, I am happy to report that the recently released firmware for the SL2 (v5.0)

https://leica-camera.com …ras/sl/sl2-black/firmware (external link)

has corrected that issue! You still have to manually select the adapted lens from the camera's menu (Menu > Camera Settings > Lens Profile) but now the specified lens EXIF data are written to the file! I have tested both R and M lenses with two different dumb adapters (Novoflex R to L and the 7Artisans M to L helicoid adapter) and it works as advertised.

Oh, and now the SL2 has perspective control like the M 10 and M11. Yay!

Anyone know the German equivalent of "Kaizen?" It took a while, but it works.

M10P taken with the SL2 and the Sigma 105 macro.

A pretty versatile lens, and can be used with the Sigma 1.4X teleconverter.

Some special sauce added with Dehancer.
