Canon has announced their new 17-120mm T2.95 Cinema Zoom Lens. Usually we have to wait until at least the first or second day of NAB for major new gear announcements. Canon was kind of enough to provide their big news a week ahead of the big show. Canon announced their original Cinema EOS lenses back at NAB 2011 and were ready to ship in 2012. So far the feedback on the Canon cinema lenses, both zoom and primes, has been a bit slow to gaining traction, but they’re running at full steam now and there’s a lot of ground to cover.

Last year, Zeiss introduced a 0% financing offer for their CP.2 Compact Primes and CZ.2 Compact Zooms which was only available for a short time. Rejoice – It’s available again and this it starts today, April 1st (no joke) and goes through December 31st, 2014. This offer allows business customers to purchase any CP.2 set or CZ.2 lens with no money down, 0% financing for 12 months. It’s really pretty simple, $83.33 per month per $1,000 financed. This means if you opt for a CZ.2 28-80mm, your payment would approximately $1,666/mo. Not too shabby for a working professional looking to up their lens game. Check out all the details over at Duclos Lenses.
I know… There’s been a few wallpaper posts lately. It’s because we’re gearing up for NAB which is right around the corner. If you’re not familiar with NAB – you should be. It’s an annual convention that takes place in Las Vegas where manufacturers and vendors come together from all over the world. There’s tons of antenna companies and manufacturers who make blink light panels that I have no idea how to use but have to walk by to get the the lenses…
All you really need to know is that NAB is basically Christmas morning for lens geeks like us. Stay tuned for some very exciting lens news straight from the show floor and giveaways from Duclos Lenses. In the meantime, enjoy this 4K photo of a Leica Summicron-C 25mm – she’s a beaut.
I get asked about shipping products to Australia quite often to which I usually have to respond based on the rules set fourth by a particular manufacturer. Most lens manufacturers have obligations to their dealers to provide a fair market price and service. This means that dealers are equally obligated to obey the rules set by such manufactures in order to respect fellow distributors. Obviously this doesn’t always happen – sometimes for better and sometimes for worse. Duclos Lenses always does their best to accommodate international customers but sometimes the rules set fourth by manufacturers are simply prohibitive. One alternative for most regional restrictions is to simply purchase your gear locally, supporting your regional market, and sending equipment to Duclos Lenses for modifications such as the Cine-Mod or the Multi-Mount.

Arri has provided a really simple, comprehensive diagram of the three different iris rod standards. It seems like there has been a lot of confusion about the proper distance from the axis of the lens to the center of the rods. A few basic details to go through here: The height of the rods (the distance from the lens axis to the center of the rods) is critical as a standard when designing accessories such as matte boxes, follow focuses, low bridges, or just about any lens related accessory. In this post, I’ll discuss the relationship between the different iris rods (15mm LWS, 15mm, and 19mm) and their associated low bridges.
15mm LightweightThe smallest and newest system to be utilized for motion picture work and as of recent, possibly the most common. The 15mm Lightweight system (LWS) is a variation of the 15mm Studio setup with roots began in ENG and DV setups. With the introduction of the DSLR revolution and tiny camera rigs such as the Blackmagic Pocket Camera and in some cases even a simple GoPro, the 15mm Lightweight system has carved it’s own place into the motion picture world commonly found on medium sized rigs such as RED and Sony cameras. The 15mm LWS is aligned to the center of the lens mount, with a relatively narrow spacing (60mm) and a fairly shallow axis to rod height (85mm).
If there was an “old school” rod setup, 15mm Studio would be it. 15mm Studio rods are the same rods as 15mm LWS but spaced farther apart (100mm), farther from the lens axis (118mm), and slightly offset from the optical center (17.25mm). Don’t get me wrong, 15mm Studio is probably the most common among high-end cinema sets based on the West Coast despite it’s age. The 15mm Studio system has become somewhat overlooked in terms of standardization with all the newcomers to the motion picture camera accessory manufacturing game assuming that the rods were aligned to the optical center. As far as I know, the reason for the offset of 15mm Studio rods was originally to compensate for weight and accessory distribution. The camera had additional weight on the “smart” side due to the viewfinder and controls so accessories such as the follow focus or motors were attached to the “dumb” side to balance out the setup. I’ll admit, the 15mm Studio standard is far older than me or anyone reading this and I’m no motion picture historian… If your 15mm Studio rods aren’t offset, then they’re not 15mm Studio.
If you’re anywhere other than Hollywood, you’ll likely find 19mm rods used as the standard. 19mm Studio is the updated version of 15mm Studio. As lenses and lens accessories became heavier and heavier, the need for stronger rods came about paving the way for a slightly heavier duty system. The 19mm Studio setup is spaced even farther apart than 15mm Studio (104mm), and slightly more distant from the optical axis (120mm) but is centered on the lens. The purpose of the 19mm system was to increase the load capacity when used with heavy lenses and reduce flexing.
Traditionally, stainless steel is king. These days you’ll find dozens of different companies producing “rods” from aluminum and carbon fiber which is fine for more 15mm LWS rigs where weight is critical and the stress put on the rods is minimal. Aluminum and carbon fiber may even be suitable for some 15mm Studio setups if they’re not demanding, but if you’re rig requires the wider offset of 15mm Studio rods, then you’re probably not worrying about the overall weight of your camera rig and should opt for a stainless steel variant. The same can be said for 19mm Studio – if you’re going to go with the beefier 19mm setup, don’t cheap out and use flimsy aluminum or carbon fiber. If you’re on the fence between 15mm Studio and 19mm Studio, there’s always 15mm HD rods. No, not High Definition… Heavy Duty. This would be a 15mm rod with a wall thickness double that of the normal 15mm rods. This provides a much more solid support with little to no flex even with a hefty Angenieux or Fujinon zoom. Iris rods will come in all sorts of lengths these days depending on their application. A heavyweight cinema zoom will call for 24″ rods whereas a DSLR rig may only require a few inches simply to attach a follow focus to the front of the rig or a battery to the back.
A simple pair of carbon fiber rods. Carbon fiber rods are usually hollow with end caps to keep dirt and dust out, but can also be found in a sturdier solid carbon fiber material.
The confusion comes in mostly when companies design and sell products that don’t conform to an industry standard. For example, a simple google search for a 15mm matte box will yield results from around the world with little to no mention of what system a given matte box is actually designed for. I’ve seen matte boxes advertised with 15mm rod holes but 19mm Studio spacing or 15mm LWS spacing but with 15mm Studio height. Some with fully adjustable offset and height, others with absolutely no height adjustment. I guess you just have to hope your camera plate has a height adjustment… Matte boxes are the primary source of confusion with the other most common accessory, the follow focus and/or motors not being much of a concern. This is because most follow focus systems will have a slide or pivot adjustment to accommodate different size lenses minimizing the standardization to simply rod size and spacing, disregarding offset and height.
Arri MB-20 II Matte box sample: Note the top pair of 15mm holes (15mm LWS) is centered on the optical center whereas the lower pair (15mm Studio) is clearly offset from the center. Also note the height difference.
Additionally, the height has been a topic of confusion in the recent past. Lets use the Red 300mm prime for example. Originally it came with a built in support, a bright red ring towards the front of the lens with a simple 1/4-20 (I think) threaded hole. If I remember correctly, there wasn’t any standardized height. You either had to use an arbitrarily adjustable, standard-less low bridge or stack bunch of washers just to attach the lens securely. It wasn’t designed for 15mm LWS or 15mm Studio. It was just a big red block with a hole in the bottom. It’s possible that Red intended the 300mm to be used with the 15mm LWS standard, but since when is a 300mm, one foot long, 6 lb. prime lens considered lightweight?!?!
While we’re on the topic of height; the other critical spec, the same chaos experienced with matte boxes can also be found in low bridges. The low bridge is the key to lens support. A lens can have a support post with standardized height and a nice 3/8-16 thread but it’s useless without a proper low bridge. A proper low bridge will be somewhat forgiving in terms of standardization with minor adjustments for height and offset, but not so much that the industry standards can be completely overlooked. With the 15mm Studio and 19mm Studio standard, a proper low bridge is easy to come by. Because of all the confusion with proper heights and standards when 15mm LWS was adopted for motion picture rigs, you’ll find that there are many 15mm LWS low bridges with a fully adjustable height. This makes them pretty useful but sometimes sloppy depending on the brand.

I hope this clears up some of the confusion surrounding iris rods and lens accessories. Anytime someone asks me what brands I recommend for a matte box, follow focus, or low bridge, I generally stick to a single rule which is stick with the established brands. A company that has been manufacturing motion picture accessories for a good decade or so will know what they’re doing and will obey the standards making life easier for all of us. Of course, there’s an exception to every rule and in this case, it’s usually budget. If you can’t afford a high quality accessory, make due with what you can, but you’ll probably end up getting the higher quality product in the end so you might as well start with proper gear.

The Summicron-C prime lenses from Leica were introduced at NAB 2013. With 2014 right around the corner, Leica is gearing up to deliver their new Summicron-C primes very soon. But how has Leica gone about producing these new lenses in a way that benefits the Leica brand as well as the cinematographer considering them as a prime lens option? There are plenty of questions that this new set of prime lens demands answers to. We’ll take a look at their performance specs, and image characteristics here.

UWZ… It’s pretty simple really. Ultra Wide Zoom. It’s not much of a zoom really with a mere 1.8x zoom range but who cares when you’re at 9.5mm! Arri’s newest zoom lens is something of a technical achievement and an answer to many cinematographers’ pleas for a high quality wide angle zoom lens option. While it’s range isn’t much to brag about, being just under 2x, it provides enough flexibility for a cinematographer to replace two or three prime lenses without sacrificing overall image quality. The real benefit of this lens is it’s rectilinear image and stunning quality across the entire image – all 33.7mm⌀ of it. Continue reading “Go Wide With Arri’s 9.5-18mm T2.9 UWZ”
Samyang originally displayed a prototype 10mm prime lens at Photokina 2012 with a few details. They recently announced the official development of their new 10mm f/2.8 prime lens. If you’re not familiar with the Samyang line of lenses, they’re a very confusing bunch which shares it’s designs with different branding such as Rokinon, Bower, Vivitar, etc. Rokinon offers their photo lenses in a cinema variety that feature 32-pitch focus and iris gears as well as a smooth, click-less aperture and T-stop markings instead of f-stop. Needless to say, this new 10mm will make it’s way into a Rokinon Cine Prime flavor soon enough. There are quite a few interesting details about this lens.

I always do my best to spread the word in regards to stolen equipment since it’s usually a potential buyer that tips off the rightful owner or the authorities of suspicious gear. As many of you know, Duclos Lenses was a victim of theft a few years back which set us back in early development of our 11-16mm lens. As a result, I take thefts such as this very personal. This time it involves a complete set of Leica Summilux-C Primes owned by a great rental house and customer of ours, CPT Rentals out of New York. The lenses were being used in the Angelino Heights area of LA at the time they went missing. CPT is distributing flyers that share a few other details that are important to spread including the name of the detective investigating the crime: Craig Marquez of the LAPD (case # 13022294) who can be reached at (213) 484-3479. The serial numbers of the lenses are as follows. Continue reading “Stolen Equipment Alert!”
The Xenon FF-Primes are only a few weeks away and are positioned to be an excellent mid-range set of prime lenses. But what if you want something with just a tad more performance? You reach for the Schneider Cine-Xenar III primes. I did a quick write up on these a few months back explaining how Schneider drastically improved the operational usability of the Xenar IIIs over the previous two versions. Unfortunately the first two iterations may have left a sour taste in some operators mouths. So what’s the best way to encourage cinematographers to give the Xenars another chance? Discount the heck out of them. Continue reading “Schneider Cine-Xenar III Rebate + Warranty Offer”
Shane Hurlbut recently took a set of the Canon Cinema Compact Zoom lenses, 15.5-47mm and 30-105mm, complete with Multi-Mount and Zoom Motor Bracket as well as the two flagship lenses, the 14.5-60mm and 30-300mm with our Carry Handle and Motor Bracket kits out for a spin on his newest project that you may have heard of – Need for Speed.
I love what Duclos has made. They are ergonomically made to flow with the lens and they also incorporate a Haden M26T motor bracket to engage the zoom focal lengths. They are built like a brick house,

Several months back, Canon held an event at their Hollywood HQ showcasing their complete line of Cinema Eos products, but focused on (pun intended) their cinema lenses. There were a couple of speakers; one ,who’s name escapes me at the time of writing this, coming from a new-age cinematographers point of view talking about the benefits of modern image sensor technology and compact, lightweight style shooting – and the other, Larry Thorpe. If you’re not familiar with Larry Thorpe, he’s basically a guru of all things image acquisition. He’s worked for RCA, Sony, and now Canon. One may jump to the conclusion that he loves Canon lenses so much simply because it’s his job being a marketing exec. at Canon… But Larry is truly passionate about his work and optics in particular and it shows.
Larry’s presentation at the Canon event revolved mainly around optics and discussed current and future technologies. Canon released a PDF which essentially mirrors Larry’s presentation at the event that I’ve linked here. Give it a read and see why Canon is making waves in the industry with their cinema optics. See the PDF below.
