  1. holy smokes... I just scanned this entire thread. I'd just like to say 'thank you' to Vijay for providing all the information.

     

    Question for you, Vijay: When you say:

     

    'The digital representation of the analog value can be 8 bits, 14 bits, 16 bits or whatever. This increases the precision of the representation, not the dynamic range. The actual dynamic range is a voltage ratio, the "dynamic range" of a 16-bit vs. a 32 bit representation is a meaningless number, since the max value - FFFF for 16-bit, or FFFF_FFFF for 32-bit represents the same voltage - the saturation voltage of the photo cell. '

     

    Does the number of bits impact the 'tonal range'? what is the metric used to refer to the granularilty *between* the shadows and the highlights?

  2. I'm curious, Jerry, to know what you did.

     

    I happened to pick up a 50mm AI 1.8 for $80 and I love it..

     

    HOWEVER - I am finding myself spending quite a bit of time in post processing correcting exposure since I cannot meter with it.

     

    Now... I hear the AF-D version calling my name..... AAAGGGGGHHH!!!!!

     

    I've only had it (the 50 1.8 AI) for a few months. Maybe I should give myself more time and perhaps my metering skills will improve. It *sure* would be nice to shoot in shutter priority with a prime lens, though is what I'm thinking.

  3. No-way would I give an 11 yro a $400 camera. That's insane in my book, but that's just me. That's just how I was raised and where I come from.

     

    I would get him a $40 AE-1 film slr *OR* a P&S with manual control (e.g. Canon A580).

     

    Those technical aspects are actually very easy and very predictable. I don't see why an 11yrold wouldn't be able to grasp them, given the right mentoring.

  4. I have the 18-55 and 55-200VR. It's a hassle to go back and forth, but I think I prefer it to the 18-200. According the photozone.de at least, the 18-200 VR has significan barrel and pincusion distortion. Any 18-200 owners care to comment?
