Summicron 50 and Lightroom Metadata

[sanyasi]

Advertisement (gone after registration)

I have a new Summicron 50 lens. In Lightroom, sometimes the metadata reads

 

Summicron 50 f2

 

and sometimes Roman numerals are added--Summicron 50 f2 (IV,V). Does anyone know what the Roman numerals are referring to?

 

Also, am I correct in concluding that there is no metadata recorded for the focus distance? I haven't seen any. I assume this is because the focus is manual.

 

Thanks

I don't own the 50 cron, but a 50 pre-asph 50 summilux, 18, 24, 50 1 noctilux, 75, 90 and 135 Tele-Elmar-M. I suppose the Roman Numericals refer to the lens version (as in my 50 pre-asph (II). Light Room displays the lens in the Develop Window (set up in preferences or Command-I). I have never seen metadata recorded for the focus distance - so I assume you are again correct.

I confirm it is the lens version. The following is the list of the tags (as of today, I suppose):

1 = Elmarit-M 21mm f/2.8

3 = Elmarit-M 28mm f/2.8 (III)

4 = Tele-Elmarit-M 90mm f/2.8 (II)

5 = Summilux-M 50mm f/1.4 (II)

6 = Summicron-M 35mm f/2 (IV)

7 = Summicron-M 90mm f/2 (II)

9 = Elmarit-M 135mm f/2.8 (I/II)

16 = Tri-Elmar-M 16-18-21mm f/4 ASPH.

23 = Summicron-M 50mm f/2 (III)

24 = Elmarit-M 21mm f/2.8 ASPH.

25 = Elmarit-M 24mm f/2.8 ASPH.

26 = Summicron-M 28mm f/2 ASPH.

27 = Elmarit-M 28mm f/2.8 (IV)

28 = Elmarit-M 28mm f/2.8 ASPH.

29 = Summilux-M 35mm f/1.4 ASPH.

30 = Summicron-M 35mm f/2 ASPH.

31 = Noctilux-M 50mm f/1

32 = Summilux-M 50mm f/1.4 ASPH.

33 = Summicron-M 50mm f/2 (IV, V)

34 = Elmar-M 50mm f/2.8

35 = Summilux-M 75mm f/1.4

36 = Apo-Summicron-M 75mm f/2 ASPH.

37 = Apo-Summicron-M 90mm f/2 ASPH.

38 = Elmarit-M 90mm f/2.8

39 = Macro-Elmar-M 90mm f/4

40 = Macro-Adapter M

42 = Tri-Elmar-M 28-35-50mm f/4 ASPH.

43 = Summarit-M 35mm f/2.5

44 = Summarit-M 50mm f/2.5

45 = Summarit-M 75mm f/2.5

46 = Summarit-M 90mm f/2.5

47 = Summilux-M 21mm f/1.4 ASPH.

48 = Summilux-M 24mm f/1.4 ASPH.

49 = Noctilux-M 50mm f/0.95 ASPH.

50 = Elmar-M 24mm f/3.8 ASPH.

52 = Super-Elmar-M 18mm f/3.8 ASPH.

Thanks.

 

While I suppose it is too late for this upcoming release of the firmware (supposedly today), if it is possible to record focus distance as metadata, it would be very useful data to have in reviewing and evaluating photos and gaining instinct.

That seems to be quite impossible, as there is no link from the rangefinder to the electronics.

No way, i guess, the M lenses are not wired and the rangefinder is a totally optical/mechanical device. The focussing distance cannot be recorded.
