'lux vs. 'cron comparison

Discussion in 'Leica and Rangefinders' started by thomas_lofqvist, Apr 3, 2002.

  1. Are the 50mm 'lux and 'cron M equal in optical performance?
    Is the 'lux pricetag justified merely by the extra stop?

    <p>

    Ps. I'm past the stage of "Do I really want/need this very expensive rangefinder system?" I mean I'm really over it. And I do :)

  2. kan detta vara en svensk landsman månne? (sorry, guys, Swedish
    question)

    <p>

    To give my 2 cents, I find the summicron lenses (currently only have
    the 35/2A, but I've tried the 50 as well) to some of the finest
    lenses around. Tack sharp, great color, virtually distortion free.
    Sure, that extra stop may come in handy, so ar I've done fine without
    it.

    <p>

    On your PS-point. Sure you want it, relative to medium format it is
    even darn right cheap! BTW, there are some great M6 TTTL deals on
    eBay now, they've seem to have dropped about $200-250 in price since
    the arrival of the M7 and the US rebates.

    cheers,
     
  3. In terms of tech specs, the Summicron is marginally better (except, of
    course, at apertures wider than f2). The extra cost isn't justified
    by the extra stop but by the shots that you can get with that extra
    stop that you wouldn't get otherwise.
     
  4. The problem is the high cost of a new Summilux compared with the
    Summicron, about $900 extra at full retail price or about $650 on the
    grey market. You have to really NEED the extra stop at those prices!
    Of course, you may be able to find much better used 'lux bargains if
    you're careful what you buy and from whom you buy it. I believe the
    resolutuion performance of the 50 'cron is better, overall, than
    the 'lux at apertures from f/2 to f/5.6, after which they are about
    the same.
     
  5. Mike... indeed, optical performance - or, as you say "tech specs" -
    are what interests me in the comparison.

    <p>

    Not really whether they throw in pictures with the 'lux purchase... ;)
     
  6. I'd like to ask Mike Dixon a question if he's still watching. Mike,
    would you have considered the 75/1.4 a good business decision given
    what the rest of your equipment looks like? I'm thinking here that
    you have the 90/2, a DR 50/2, maybe even a Noct.?
     
  7. Even at the very fair price that Jack Flesher was asking ($1200), I could not have justified the 75 'lux as something I needed for business (considering I already had a 90 Summicron). Of course, now that I have one, I'd hate to be without it. If I had to choose between the 75 and 90, I'd be bidding farewell to the 90.
     
  8. could not have justified the 75 'lux as something I needed for
    business

    <p>

    So you made, bad choice.You would not make the choice again.Simple
    yes or no...cut the waffle.
     
  9. No, I made an excellent choice in accepting the generosity of some of
    the kind members of this forum (another chapter or two is coming up
    within a week!). However, it would have been a bad business decision
    to pay $1200 for the lens at the time. If you cannot comprehend the
    question or the answer, perhaps you shouldn't comment. (Yeah, right!)
     
  10. Thanks Mike. Looking forward to your next chapter.
