      I'm selling a copy of the smallest Anamorphic lens in the world, the Baby Hypergonar 1.75x. It's been said there were only about 50 of these ever made. Designed by the OG, Henri Chretien, and made in 1957.
      It is in great condition. Comes with a little black carry case. Really lovely copy, no scatches, fungus, haze. Body is in great shape. There are a few small coating blemishes on the front, but they are so hard to see I couldn't even capture them in the pictures, and they don't show up in performance. 
      Can be used by just focusing your taking lens or in combination with a single focus variable diopter. Neutral unique flares and beautiful rendering.
      - PRICE: $1500 USD
      - LENS NAME: Baby Hypergonar
      - CONDITION: Near Mint Optics, Mint Body
      - PAYMENT METHOD: PayPal
      - LOCATION: Los Angeles, CA, USA
      - FEES & SHIPPING: PayPal fees and shipping paid by buyer.
       
      Please PM me if interested

      Does the A7s' high-ISO capability effectively negate the dof advantage I’d otherwise get by choosing a Micro 4/3 camera? (Assuming I’m trying to achieve maximum dof.)   In other words, shouldn't I be able to match even the deepest dof I could get with an m4/3, just by stopping-down and boosting the ISO…and of course changing the lens to match perspective, etc?   Here's the thing: I'm bumping up from teeny-chip camcorders with 10x (yes, that’s double-digits) crop factors, and from this point-of-view, and in light of the A7s, the dof advantage of a 2x crop vs. FF seems almost non-existent. I’m wondering if I shouldn't skip over the m4/3 sensors and go with the A7s. (I’m usually in low-light, high-contrast environments, so the appeal of the A7s on other fronts is obvious.)   There are a boatload of questions about the still-unreleased A7s, but in terms of dof, does my thinking make sense? Thanks.
