    So many of the popular cameras have increasingly higher usable ISO. AND popular lenses are slower with apertures of f5.6 and slower.

    So is fast glass obsolete? Especially given it's weight and price?

    Here is Steve Perry's opinion.....FWIW.....

    Agreed. There is NO free lunch. I particularly notice the DOF is not as "creamy" (and is often a bit busy) when shooting f5.6 glass. I haven't noticed the lessening of dynamic range as much, since I watch my historgram, especially if I value the shadows or highlights, and expose accordingly. Thus it's not often I need to significantly adjust areas in post.

    Although I have to be careful. Steve is causing me to lust for the 600mm!!!!!!

  4. I thought Steve gave a thoughtful and reasoned answer to the question. Now if only I could afford a 800mm F5.6 or a 600 F4 lens...

    yep, Big yes from me and the other caveat is it is always better to be closer and or also have big glass, Cropping can only do so much. Shooting through more air at smaller subjects creates more “atmospheric blur”. More pixels on subject always helps.

    Thanks for sharing Karen!
     
  6. I'll also join in with a complete agreement with Steve's article. The entire article is a very good read.
     
  7. yep, there's a reason big glass costs so much...

    And Karen - you know you need that 600 f4. :devil:;)
     
  8. I told you to buy the 600, remember? I also agree with Steve, however with my advancing age, I WILL be first on the pre-order list for a 600 PF should Nikon release one(y)

    The current 600mm FL weighs the same as my 500mm/f4 I'm hauling all over the place!!!! I said I was going to sell my 500mm after my last trip, just haven/t committed to the many, many thousand dollars it will take to replace it! LOL! And my 500mm is so dang sharp, I hate to give it up!

  12. Great read - just affirms my commitment to using the fastest glass I can afford for what I shoot the majority of the time...
     
  13. Yeah, exactly. His is not a click-bait site, but rather a well reasoned, data driven one. He's not sold his soul to sponsors.

  14. Initially I bought fast primes because my f2.8 zooms were too slow (aperture-wise) for a lot of my available light shooting. Nowadays the zooms are just fine, but I still love my fast primes for subject isolation.
