    • In Camera or Post Effects/ Techniques that help replicate Global Shutter Motion Cadence?
      Thanks Ebrahim. Interesting strategy that I for one would be curious to see.
    • In Camera or Post Effects/ Techniques that help replicate Global Shutter Motion Cadence?
      There's software that can counteract rolling shuutter abit (basically rolls the image the other way and crops in for the missing edges to disappear). It's not good. Makes motion look worse IMHO. 

      The problem is that we still don't know motion cadence actually is in order to technically replicate it. 

      But it's one or a combination of those: 

      1- frame rate 
      2- shutter angle/speed
      3- rolling vs global shutter
      4- Codec motion compression algorithms (intra frame / Ling GOP, bitrate blocks on movinh edges etc)
      5- An imaginary quality we associate with some classic cameras known for unique IQ (F35, 1Dc, BM 2.5k, Bolex, Pocket). 

      Keep in mind we actually see that the sony f35 has better motion than sony f55 and f65. We see 1DC motion better than c100, C300, and c300 MKII. We see better motion in blackmagic 2.5K and pocket cinema camera than Bm4K and Bm4.6K. We see better motion in canon 550D/5D than GH4.

      ALL of these examples clearly show inferior camera we claim have better motion than their superior newer better models. just something odd and worth taking note of. 

      Only if I had access to a rental house to make a few fimple tests and we'd understznd clearly what motion cadence is. 

      Any one with many caneras can volunteer? @Andrew Reid owns a camera store and it'd make an awesome blog post, an enlightening one all over the world. 

      I believe you have a 1DC, GH4, NX1, C500, Fuji Xpro2, FS100, d750 and others. Test motion. 

      First a 1dc (a camera known for great motion cadence) vs a GH4 (One known for bad stuttery cadence). 

      Set up the two cameras side by side on a trpod/s. Point then at a Fan set low speed. Use lenses matching FOV. Do this test at 24p at 1/30s and 1/50s and a high 1/250-ish to analyize the frames more profoundly. 

      Just a second test, the two caneras placed on the same triopod, and make a normal pan of a scene. At the aforementioned settings. 

      This would allows us to see if there's a difference in the reported shutter speed by manufacturers (the gh4 when I had it looked like 180 degree only a 360. Makes me worry this might be just it!). We'll be able to see how each codec affects motion in the frames by analyzing the same ones from the two cameras. Would make us believe we're just seeing things if both looked identical in motion abd that it's imaginary and based on subjects/cinematography/colouring. 

      Any volunteer? It's an important test, it's one that will give us the technical data on the last unknown image quality charachteristic.
    • Lenses
      Contax Zeiss 50mm f1.4 aej I love the Contax Zeiss lenses. The size, build quality and look of the images have a unique signature to them. These are the "real zeiss" lenses to me. They have more of the 3D pop people mention and lens of the clinical sharpness of the modern zeiss glass
    • Best 82mm Variable ND and Circular Polarizer?
      Hi guys any advice on a best bang for buck variable ND and circular polarizer? Just got the Sigma 50-100mm delivered to me but totally didn't count on the front element being so massive. On location in remote Northern Canada so I have to order parts online, no nearby shops. I usually play it safe and just buy Tiffen but I think I remember seeing SLR Magic having one of the most neutral variable NDs available? Apologies if there's already a thread for my answer. All I have is a smartphone and lousy data connection, having trouble doing good research.
