How Much Is a Used Leica M6 TTL Worth? (2026 Price Guide)

Usually yes. Leica services many current and recent models, and independent specialists handle older and discontinued bodies, including the clean-lube-adjust (CLA) that vintage cameras often need. Parts can be limited on older or electronic models, so budget for a possible service and factor a CLA into the price on a body that has not been serviced recently.

The M6 TTL has a photodiode in the base of the body that reads the flash light reflecting off the film during the actual exposure, then signals the flash to cut off once enough light has been delivered (off-the-film, or OTF, flash metering). This is the one feature the M6 classic lacks, and it only works with a dedicated flash: Leica's own SF-20 (and later SF-24D), or a Metz flash in the SCA-3000 system fitted with the SCA-3501 adapter. Without one of those the camera still fires any flash on the hot shoe, but only in manual flash mode with no automatic exposure control. If you never shoot flash, the TTL system is the main thing you would pay extra for and get no benefit from.

The M6 classic shows only two red arrows in the finder, while the M6 TTL adds a center red dot so a balanced exposure is confirmed at a glance instead of guessed at between the arrows. The shutter speed dial is also larger and turns in the opposite direction from the classic, deliberately matching the direction of the finder arrows so you turn the dial toward the lit arrow to correct exposure. The dial gains a dedicated off position that powers down the meter to save the battery, which the classic does not have. Beyond TTL flash, that is the short version of classic versus TTL: the same camera with more legible, more intuitive metering controls.

The M6 TTL launched in 1998 with 0.72x and 0.85x finders, and the 0.58x was added to the line in 2000. Pick 0.72x as the all-rounder; it shows 28mm to 135mm framelines and suits most users. Choose 0.85x for the largest, most precise patch if you mostly shoot 50mm and longer, accepting that there is no 28mm frameline. Choose 0.58x if you favor wide lenses or wear glasses, since it is the only M6 TTL finder with a 24mm frameline. The magnification is etched on the back of the top plate near the finder, so verify the version before buying.

Yes, the shutter is entirely mechanical, so every speed fires normally with a dead or missing battery; the battery powers only the light meter and the TTL flash circuit. It takes two SR44/LR44 cells or one 1/3N lithium cell, the same as the M6 classic. The off position on the shutter dial lets you shut the meter down between uses to extend battery life. So a body with a non-working meter is still fully usable as a manual camera with a handheld or phone meter, which matters given the repair situation below.

This is the most important caveat for the TTL and the one place it is worse than the M6 classic. The TTL meter relies on circuit boards that must be programmed and calibrated with Leica's own software, so unlike the classic's more serviceable meter it generally cannot be rebuilt by independent specialists once a board itself dies. Leica ran out of replacement M6 TTL main boards several years ago, and well-known techs such as DAG can fix related faults like cold solder joints or corroded contacts but cannot replace a failed board. Confirm the meter responds correctly across the speed range before paying a working-meter price, and treat a dead-meter body as a manual-only camera priced accordingly.

Yes, several M6 TTL editions command large premiums over standard black-chrome or silver-chrome bodies. The best known is the black-paint Millennium of 2000, with brass top and bottom plates, an M3-style wind lever, and 2,000 examples numbered on the accessory shoe. The LHSA black-paint edition of 2000 is also sought after, with roughly 1,150 made across the three finder magnifications, and the all-titanium version is rarer still. Value is driven by brass-and-paint construction, original boxes and papers, matching numbers, and paint condition; verify engravings and serial ranges against known figures, since these editions are faked.
