WHAT ARE THE CREATIVE ADVANTAGES OF USING THE ARRI ALEXA LF AND ARRI SIGNATURE PRIMES TOGETHER? SAM MEASURE TECHN I CAL SPEC I AL I ST
you have more creative options than ever. Arri has now completed its range of Signature Primes and you can really see how designing a lens for full-frame from the ground up has made a difference. By jettisoning the PL mount and replacing it with the new LPL (Large Positive Locking) mount, Arri opened up a larger diameter on the lens and decreased the flange depth. This means the lens can be relatively lightweight, while maintaining a fast 1.8 T-stop. Another nice touch is Arri adding the ability to use filters on the back of the lens with a detachable magnetic rear filter holder. This gives DOPs the option to muddy it up on the lens and imprint their own image into the system, enabling them to put their own fingerprint on their work and ensure that a look, which wouldn’t be achievable in post, can be burnt in. I think we’ll continue to see manufacturers trying to make the perfect lens, with options to mess with it. The Arri Signature Primes are near perfect with their high resolution, great contrast and good design in terms of optics.
ull-frame is definitely a format whose time has come and, a few years after the release of the first full-frame cameras, at CVP we are still seeing a steadily increasing amount of queries
about shooting in it. Of course, its main benefit is the increase in format size. Jumping from Super 35 to full-frame gives you all the benefits of using a larger plane; you can get closer with the same lens for more intimate shots from a different perspective, shoot at the same distance with a longer lens to get a shallow depth-of-field, 0r simply shoot from the same distance and get a greater field of view. The increase in film area also means a reduction in grain size and an increase in resolution, though different manufacturers have different approaches when it comes to tracking that through to the sensor – some have prioritised resolution, others dynamic range and lowering noise. Either way, full-frame opens up some interesting creative possibilities. Add in specialist full-frame lenses and
