Sigma Cine Primes and Zooms – all you need to know.Using Lens Extension Tubes reduces the minimum focus distance of lenses.E-Mount Lenses – perfect for the Sony FS7.What it is like to shoot with Uncoated Lenses.We have discussed lenses at length before and so will try not to get side tracked too much and stick to the FF bits. The very useful website by Abelcine here demonstrates this very effectively.
#35mm frame lens full
The second issue worth mentioning is that for the Sony compatible lenses, working in Full frame means that the perceived field of view (in full frame mode) is wider than that of S-35, owing to a larger image size being generated by the lens. Perceived Field of View for Full Frame and S-35 So it’s all very well having these big sensors but we haven’t yet looked at the fundamental requirement of these big things, which is a lens that can deliver an image big enough to cover them. Other variations to note are the Alexa 65 which is based on a sensor size emulating 65mm film travelling North-South and IMAX which emulates 65mm travelling East- West, both of which are therefore postcard size pictures. The disadvantage in film terms was that it used twice as much film as a vertical pull down camera and so was relegated to the visual effects world fairly early on in its lifetime. The advantages were a much bigger picture, therefore higher quality as more film grains were used per frame to present a smooth fine grain image which was extremely useful for visual effects and it’s the same advantage in today’s digital cameras. Super 35mmĪ term derived from film that has several parts to understand. And so the most commonly used aspect ratio (that of our TVs) is 16:9 (1.78:1) but it can be used on any size sensor from 2/3rds size chain cameras up to Alexa 65mm and IMAX-which is a massive postcard size picture (or frame) compared to the B4 cameras but importantly the aspect ratio is exactly the same.Īspect ratio is a means to define the ‘look’ of a piece but sits on top of the actual dimensions of the sensor being used so when you see the term ‘for a given aspect ratio’, it means the pictures match in terms of the framing box but do not necessarily match in terms of area/size of that box and this is an important distinction when explaining FF. Technical Stuff Dimensionally Challenged:īoth Super 35mm and Full Frame are not new terms or concepts in fact they are older than most of us and both are derived from film terms.īefore we start however it is important to clarify one parameter that will be used a lot on this piece and that is aspect ratio.Īn aspect ratio does not define the size of a sensor it is the fixed relationship between the horizontal and vertical axis and could be any size physically. Technical Stuff – about Image Sizes and Ratiosġ.These larger sensors are known generically as Full Frame (FF) and this article will try and explain the differences between that and Super 35mm size sensors and what the advantages/disadvantages the FF world can offer along with some description of what the different cameras can achieve. We have seen the advent of digital sensors replacing film and then HD sensors and then 4K and 8K and so on and whilst the increase in resolution (more pixels-more detail and colour subtleties) has been important, manufacturers have also started to release larger size sensors to not only accommodate the increased pixel counts but to allow the film maker to utilise the benefits of a larger sensor.
#35mm frame lens upgrade
Mostly these modifications or improvements have an emphasis on an upscale in quality to tempt the consumer to upgrade their hardware or VoD packages and of course this means the origin of the content must also have been ‘upscaled’ to deliver on the retail promise. What are the advantages and what gear will I need? Introductionįilm making has always had ‘pinch points’ of innovation, some of them more successful than others and in recent history more often than not driven by the retail thrust to sell more TVs- HD, 3D etc. To shoot Full-Frame or S-35? Are there really artistic reasons for shooting on FF?
