    You like that Kiron, Arnab? your pics made me get one a month ago...
     
  2. "Tell us more about that life size adapter ... is it a close-up lens??"
    Nah, it's closer to a teleconverter in concept. It's a dedicated bit for the old (Kiron built) Vivitar Series 1 90mm f/2.5 Macro. The native lens focuses from infinity down to 1:2. If you insert the life size adapter between the lens and the body, you get down to 1:1 (and the lens had a special set of markings for it).
    It's actually kind of like an extension tube with 4 corrective elements in it. You can't focus to infinity with it installed.
    Apparently it works with some other lenses? Mine is 'in the wind' (stolen), though I still have the lens.
     
  3. Peter,

    if my memory is correct, this life-size adaptor will keep the speed of the master lens. Yes, the lens will loose some f-stop values as it it focused closer, but this particular life-size converter prevents the whole lens/converter combo from losing f-stop values which normally caused by attaching conventional extension tubes.
     
  4. Last but not least,

    this is another stunning job Arnab!

    As has been said many times, and as Todd points out, this tube with corrective elements does nothing other than correct some aberrations at highre magnifications.
    It is better than Nikon's PN tubes. Lenses behave exactly the same when it comes to light transmission.
