  • he reads the teleprompter well

  • i'm sorry i missed that, are you saying that most digital slr camera's for amateur use come with equiped with a compact mid range zoom with relatively slow aperture? haha

    Seriously though, this is a great lens, I wish you'd do a mk II with more acurate focus though!!

  • its hard to pee with an erection :)

  • Exclusively. Now repeat :p

  • I got this a little over 2 weeks ago and I am very very happy! Will save up for a 70-200mm 2.8!

  • what's the red glas inside the camera?

  • @icecubemovies or maybe to read what he has to say.

  • Why is there a laptop on the desk? Considering he never uses it during the video. Just to brag perhaps.

  • Okay, I'll humor you. Are you suggesting that because FOV is mathematically derived from focal length and sensor size, this implies a relationship between these two properties? So there is also a relationship between the width and length of a plane, because those mathematically determine its surface area? And between the price of an item and the amount purchased, because they determine the total price of an order?

  • @rvdw98

    that's really a shame, if you have time you could read the wikipedia article entitled "Angle of View". They explain very clearly the relationship between sensor size and focal length, and how FOV is derived from those two components (mathematically). I hope this helps you develop a healthy technical knowledge of cameras. I guess what matters the most is that i understood him, and most other experienced photographers will understand what he's saying as well. adieu!
