Battery Sharing

The Leica Q2, Q2 Monochrom, SL2, and SL2-S all use the same battery. The SL and SL-2 can charge in the camera with USB-C, so if you use a Q and SL2, no need to take the external Leica charger with you.

Group Selfies

Group photo with you in it too? Set the interval time to take 10-15 shots, one second apart. When everyone is ready, press the shutter, join the group and 10-15 seconds later you have several shots. The first few will have you entering the frame, but the chances of one or two frames with everyone’s eyes open and looking good are greatly increased.

Wash Me!

Microfiber lens cleaning cloths (and lens cleaning fluid) are a great way to gently clean lenses and viewfinders. You can and should wash these cloths and air dry them from time to time.

Easier Lens Mounting

When mounting a lens onto a M body, it is much easier and safer if the lens is pre-set to minimum focus distance. It avoids early engagement with the rangefinder ‘roller’.

Easy Mac Backup

A super-easy method for backing up original photos (and all files) on the Mac without buying a cloud subscription is to use and app called SuperDuper and an external drive. 

Where Did My Profiles Go?

When updating Mac OS, you will likely lose printer Manufacturer paper profiles (Epson in particular).   The solution is to go to System Preferences/Printers and Scanners and delete the photo printer.  Then add it back (recommended to select the Manufacturer’s drivers and not “Airprint”) and restart your system.  This will restore all the original paper profiles.

Scanner Fix

If your Nikon LS4000 stops working,  don’t panic.  Contact Gleb Shtengel (   He has the ability to fix almost any problem, including bad boards, at extremely reasonable prices.  A fix is usually around $200.

Speedy Drive Setup

Faster image access: two external hard drives configured in a RAID 0 array will speed up image access. Don’t forget to keep a separate backup of all the images because if one of the disks in a RAID 0 array fails, you will lose everything.

Lens Shades and Series VII Filters

Did you know that both the 12504 and 12501 lens shades for the 35 Summilux Canada and the 21 Super-Angulon f3,4 (respectively) can take Series VII filters in the shade itself? The Super-Angulon f3,4M lens can also accept e48 thread-in filters, but if you have old Series VII filters kicking around, put them to good use!

Close and Closer

The newly announced 35mm APO M lens from Leica is a technological wonder. It close-focuses to 0.3M. But don’t forget, the 35mm SL lens close-focuses to 10 inches (on the SL, SL2 and SL2-S of course).

Repair Discounts

If you need service on your Leica camera or lens, your LHSA membership entitles you to 15% off (USA) and of course, Leica will do a great job. If their backlog is too long, you may consider sending your gear to Don Goldberg ( or Youxin Ye ( who both do excellent work. We’

Color Space

Many people ask about the difference between sRGB and AdobeRGB color spaces. The shortest explanation is to use sRGB if you will only ever view the image on a screen. If you intend to print (someday) then use AdobeRGB.

Also note that that Summilux-M 24mm f/1.4 ASPH lens uses only series VII filters, Finally, note that the 12504 filter will also fit the version 1 of the Summicron-M 35mm f/2 ASPH lenses (and the various brass editions including the black paint, silver chrome and black chrome versions). This means you can use the series VII filters with two current lenses in a wide angle kit. The Summilux-M 21mm f/1.4 ASPH uses the series VIII filter which is larger and does not fit these lens hoods.
