In 2008 the DSLR revolution was launched by the Canon 5D Mark II. For the first time, large sensors for filmmaking became affordable - and with it, a shallow depth of field synonymous with cinematic imagery became available to the masses.

UPDATE: This post is no longer updated and is now out of date. This post was written years before the RED Monstro, Sony Venice, Arri Alexa LF and all the other full frame (and larger) cameras were available! I now have a dedicated page here that I can continually update and add more lenses to.

The 5DMkII however used a full frame sensor - 36x24mm in size. This is larger than a Super-35 sensor (or film cell) typically used for filmmaking, meaning regular cine lenses are simply not big enough to use with the full frame sensors. For a while, DSLR shooters were limted to using regular DSLR lenses - which, whist optically can be fantastic, lack much of the functionality and mechanics that set apart cine lenses from photo lenses.

Fulfilling this need, Zeiss were first to the party with their CP.2 lenses. Using the same optics as their ZE/ZF.2 full frame, photography lenses, but rehoused in a cine body. For a long time, they were the only viable option for full frame cine lenses and even today, are a very popular option.

Not only was full frame/DSLR shooting becoming extremely popular, but digital cinema camera sensors started becoming bigger. In 2013 RED started producing the Dragon sensor which is larger than Super-35 - fueling the need for larger lenses. In the mean time, Canon and Schneider had been busy and both now have their own lines of full frame primes - the CN-E and Xenon FF lenses respectively. Between those two and Zeiss, they have most of the market covered - and is often what's seen on the front of a RED!

That is until recently however. Samyang already have a line of cine style lenses - albeit mechanically nearly identical to their photography lenses but with a declicked aperture and geared rings. To compete with other true cine lenses, Samyang have rehoused their lenses into proper cine bodies and are called Xeen. The coatings are reportedly different, resulting in a slight improvement to some aspects, however as the optical formulas are the same, they are largely comparable in quality to their photography lenses.

Not content with what the market had to offer, in 2015 Steven Kisilevich in Germany decided to make his own set of full frame primes - Celere HS primes.

And finally, Sigma, recently lauded for their highly successful 'Art' series of photography lenses, has decided to enter the cine market too, last month announcing a set of full frame primes along with both full frame and Super-35 zooms. Currently there is no word on price or availability, but no doubt will be priced similar to it's contemporaries.

Below is a table comparing the offerings from all of the manufacturers. Information is taken from their official websites and as EF is the only consistent mount across all the lenses, specs are representative of this mount; size and weight will vary slightly with different mounts. Blank information represents a 'no' or currently unknown.

Where possible, actual retail prices have been used, otherwise the RRP has been provided. Prices are of course subject to change and are therefore reflective only and are accurate at the time of writing. Purchasing a set of 4 or more lenses is usually cheaper too.

Data ranges are usually as a result of the widest and/or longest focal lengths. These are often slower, heavier and more costly etc. Most lenses across any given set are usally consistent sizes and speeds.

So what comparisons can we draw from this?

The Zeiss CP.2s are the smallest and lightest, most of which weigh only 900 or 1000g. For this reason, they're probably the most popular choice for applications where weight is a serious consideration - namely aerial and gimbal cinematography. They're also relatively affordable, further popularising them. The set has the greatest range of focal lengths, however their speeds vary. Most of the lenses are T2.1, though the 35, 50 and 85mm lenses are also available in a 'Super Speed' variant at T1.5. Some of the wider lenses are slower at T2.9.

Based on their renowned DSLR lenses from their 'L' series, the Canon CN-E primes are the fastest. The 50 and 85mm lenses are T1.3 - the fastest cine lenses outside of much more expensive cine glass such as the Zeiss Master Primes and the only lenses this fast that cover full frame.  The 24 and 35mm lenses are T1.5, the 135mm is T2.2 and the 14mm, as is the case with many wide angle lenses, is the slowest at T3.1. Interestingly, the CN-Es are only available in EF mount, presumably in a bid to push their own mount as a serious contender for cinema applications. Their cine zooms are available in both EF and PL, and it is possible to convert CN-E primes to PL by third parties such as Duclos.

The Schneider Xenon FF lenses are typically a little cheaper than the Canon CN-E primes, with only the 25 and 18mm lenses being (unfortunately much) more costly. The 18mm is 1/3rd stop slower at T2.4; all of the lenses are the same size with the exception of the 135mm which is about 1cm longer.

The Samyang Xeens also bear the traditional full frame prime design, the same as the CN-Es and CP.2s: short and wide. They're by far the cheapest option at almost half the cost of its competitors. The 14mm is, like the Canon, the slowest at T3.1; the 16mm is T2.6 and the 135 is T2.2.

The Celere HS lenses are comparatively small and light, second only to some of the CP.2s. Their biggest selling point is complete uniformity - all the same size and weight, perfect for steadicams and gimbals, eliminating the need to rebalance. An 18.5mm is in the works, however this will be T1.6 and unfortunately won't have the same weight or dimensions.

Until they're released, we won't really know how good the Sigma FF primes are and how they really compare, but if the specs are anything to go by they look excellent. T1.5 across the range means the 20mm is the fastest lens you can get that wide for full frame. As an added bonus, they all (along with Sigma's cinema zooms too) come with a lens support foot, plus the aesthetic design of them looks really great. No other lenses have the front diameter, filter diameter and image circle dimensions engraved into the lens barrel!

Despite all of these specs and comparisons, the only two factors that should really affect a purchase decision are price and look. Work out which ones you can and can't afford, and from there, see which you like the look of most - some are warmer or cooler than others, some are sharper; it's all personal preference. There are so many things that contribute to the look of a lens that can't be quantified. If you can, get some hands on time with them and test to see which you like the look of most. Only then will you find the lenses that you're happiest with.
