What actually differs
- Both open to f/2.8, so neither has a speed advantage.
- The Meyer-Optik Gorlitz Trioplan 100mm f/2.8 is cheaper. Typical used value is $450 against $480, a gap of $30. Ranges: $250 to $900 versus $300 to $800.
- The Meyer-Optik Gorlitz Trioplan 100mm f/2.8 is longer at 100mm against 90mm, a 10mm difference that tightens framing slightly and increases background magnification.
- The Meyer-Optik Gorlitz Trioplan 100mm f/2.8 is the older design; production began around 1950 against 1964 for the Leica Elmarit-R 90mm f/2.8 (1950s-1970s versus 1964-1996).
- They use different mounts, Leica R and M42, so each needs its own adapter. Both reach infinity on mirrorless bodies with a plain mechanical adapter.
- Construction differs: 5 elements in 4 groups for the Leica Elmarit-R 90mm f/2.8, 3 elements in 3 groups for the Meyer-Optik Gorlitz Trioplan 100mm f/2.8.
Which one to buy
On the catalog data the Meyer-Optik Gorlitz Trioplan 100mm f/2.8 wins on the $30 lower typical price, and the Leica Elmarit-R 90mm f/2.8 gives up nothing measurable in return except its own rendering, described below. Condition and variant matter more than the spec sheet at these prices.
Minimum focus distance, weight, and measured sharpness are not in the catalog, so this comparison does not claim anything about them.
