The 2/3″ 3k interchangeable lens Scarlet can take any lens mount and almost any lens, but 2/3″, 16mm and B4 lenses will not have any crop factor.
16mm Lenses
There is some question if all 16mm lenses will be able to resolve the full 3k resolution. The premium quality S16 lenses should look great. Until we actually have a Scarlet to test this on the 2k mode on the RED One camera will have to do.
- Cooke 9-50mm 16mm t2.5 This zoom lens can be found for around $2k – $3k. Kip Kubin on reduser has posted a great still from this lens used in the 2k mode on the RED One camera.
Some images of the Cooke 9-50mm lens:
Be sure to avoid the RX versions of the Angenieux lenses as they are designed to focus through a prism just like B4 lenses.
- Angenieux 12-120mm
- Angenieux 15-150mm
- Angenieux 10-150mm
- Angenieux 9.5-57mm F1.6 Larry McKee has generously provided some great frame grabs from this lens used with the 2k mode on the RED One.
- Angenieux 17.5-70mm F2.2 We will try to get some stills and footage from this lens up soon. In the meantime, here are some images of the PL converted version of this lens:
- Zeiss 10-100mm
miniRED Mount
The miniRED primes are likely to be the best match for the 2/3″ interchangeable Scarlet. The first four lenses in the set are really fast at t1.5 and only cost $950/lens. The image of the dog below was shot on a prototype 25mm miniRED and is the only shot RED has released from these 2/3″ lenses. RED will be making 6 x 2/3″ format miniRED primes:
- 6mm T1.5
- 8mm T1.5
- 16mm T1.5
- 25mm T1.5
- 50mm T2.9
- 75mm T4
B4 lenses are meant to focus on the sensor through a prism so will look best with a special mount with an extra glass element. Without the prism there will be some chromatic aberation, especially on wide angle lenses. The RED One currently uses the B4 mount made by Abakus so it stands to reason the Scarlet and Epic will as well.
S35 Cinema and FF35 Still Lenses
The modularity of the DSMC system allows us to put any mount on the 2/3″ Scarlet even if the lenses are designed for a larger sensor. A lot of people have S35 cinema glass and FF35 still lenses sitting around and the good news is that they will indeed work with the 3k Scarlet. The big downside is that there will be a serious crop factor with these lenses so it will be tricky to get any wide shots.
S35: Your traditional cinema lens will have about a x 2.47 crop factor when used on the 2/3″ Scarlet. This means a Zeiss Super Speed 18mm (typically the widest in a set) will have the equivalent field of view of a 44mm lens.
FF35: FF35 lenses fare even worse, which is unfortunate because Nikon still lenses are definitely the cheapest option for good looking glass. FF35 has a x 3.56 crop factor meaning an 18mm Nikkor will have the equivalent field of view of a 64mm lens.
