More F3 Lens Options

More F3 Lens Options

I wrote a quick review about a month ago giving some good choices (and bad) for the Sony F3 when it comes to PL mount lensing. After the dust has settled and I’ve had some more time to try all of the options first hand, I’ve come up with some good ideas for the cinematographer on a budget as well as the pro looking to go Sony. I had heard of people using a Nikon to F3 adapter that basically replaces the PL mount but I hadn’t seen one in person until I went to NAB this past week and saw it for myself. The product comes from a company called MTF Services and allows the user to attach native Nikon mount lenses to the F3.

This opens up an entire world of high quality optics to use on the F3. Nikon announced they have sold over sixty million (60,000,000) as of April, 2011. That’s insane! But I believe it. This means that the old manual lenses I love so much for cinema can now be used natively. Even the newer Nikon “G” lenses can be used. You know, the plastic lenses without an aperture ring on them… Yeah. Nikon is going the way of “gelded” lenses which eliminate the manual aperture control ring. Their entire line of new pro zoom lenses including the 14-24mm, 24-70mm, and 70-200mm, are all G lenses and lack that manual control. Nikon did leave the little lever that the camera slaps to close the aperture down in the lens which the MTF mount utilizes to control even the newest crop of G lenses that lack the manual control. Accomplished by adjusting the blue ring on the outside of the mount adapter, full manual control is enabled on all Nikon lenses. The G lenses obviously wont have an aperture scale or any indication of what f-stop you are using, but it is a compromise after all. If you want to step it up a notch try using the Zeiss ZF.2 primes with an F3. What a dream team! the only thing these lenses lack for motion picture use is the features of their big brothers, the CP.2. The ZF.2 share the exact same glass as the CP.2 but lack the focus gear, smooth aperture movement, and uniform front diameter. This is all overcome with the Duclos Lenses Cine-Mod that adds a seamless focus gear, 80mm front ring, and a creamy smooth aperture movement. Obviously this option is a little self serving for me since Duclos Lenses provides the Cine-Mod and the lenses but I sell them because I like them. I don’t like them because I sell them.

I haven’t seen a Canon Eos mount for the F3 yet but I suspect it’s not too far off since everyone already converted their Nikon mount lenses to Eos to use of their 5/7D. I’m looking forward to more mount options on the F3. I think it’s a great platform that allows the user a good compromise between indie DSLRs and a RED camera. Obviously there isn’t one camera that does it all and the same can be said for the lenses. This can be said for just about any manual Nikon mount still lens and the F3. There are also a few more lenses that were announced at NAB that would work well like the lightweight Angenieux zooms. I think most people would prefer to keep a F3 rig fairly light and avoid attaching gnarly heavy glass like the RED Primes and Master Primes. While I’m sure the final product would benefit from the beauty of Master Primes but if you’re shooting with Master Primes and an F3 it’s probably because you blew 90% of the budget on the lenses and didn’t have another choice. There are many more options when it comes to still lenses on the F3. While there may not be adapters to attach lenses like the Leica R series, you can always convert Leica R lenses to Nikon mount and still use the MTF mount. Be careful though, too many adaptations and you’ll start to introduce unwanted mechanical slop. Keep an eye on added components and calibrate often. Also, make sure you read up on which lenses work well before you invest a fortune on rare lenses from Ebay.

My advice is to try as much as you can. Don’t believe all the screen grabs you see online. Go out and try new lenses for yourself. Find a shop that will let you play with the lenses and shoot your own tests. You be the judge.

Photo Collection of NAB 2011

It’s that time of year once again. Duclos Lenses closes up shop except for those few unlucky employees who stay behind to keep the wheel turning. This year everyone is flying from LA to Vegas… What a waste. I prefer my loyal automobile to get me there in about the same amount of time as those flying fools. I’ll be snapping photos the whole way there and while at the show whenever I find something cool or interesting worth sharing. A virtual photo tour, as it were, for my guests to enjoy. I’ll do my best to utilize my plethora of Apple and Nikon/Canon toys to show as much as I can, as quick as I can. Please feel free to ask questions or request specific photos and I’ll do my best to accommodate. Now onto the photos!

 

UPDATE: Between WordPress’ irritating interface and the Hilton’s sluggish (at best) wifi, I’ve decided just to upload all to Flickr via my 3G iPad connection. Click the link below for the gallery. Enjoy!

Angenieux Adds 45-120mm to Their Optimo Line

Angenieux Adds 45-120mm to Their Optimo Line

Angenieux has long been the standard for cinema zoom lenses and certainly isn’t stopping anytime soon. NAB brings out the best in new lens manufacturers (and sometimes the worst) so Angenieux took the opportunity to announce their new addition to the Optimo series of lenses. This time it’s a 45-120mm. A little on the longer end of an all-purpose zoom, this will share a lot of the same features as the other light weight zooms like the 15-40mm and the 28-76mm Optimo. It will cover a full Super 35mm sensor/film utilizing a 31.4mm image circle and will feature an interchangeable mount with options for PL, Panavision, Nikon F, and Canon Eos.

The focus scale has 320° of rotation which is about as much as anyone could every want and offers separate interchangeable metric and imperial scales. It will weigh in at 4.3 lbs. making it perfect for lightweight, steadicam, and 3d rigs. It’s a constant T2.8 which isn’t the fastest zoom in the world, but it’s certainly not the slowest and matches well with other pro cine zooms. I’m sure we can expect the same accuracy and quality as the rest of the Optimo lenses. It’s focal range, 45-120mm is a little long even at the wide end giving it a horizontal angle of view of 27.4°-10.5°. A 45mm in a S35 frame is fairly tight and 120mm on the long end gives it a nice versatile throw. It’s 2.7x zoom ratio drops it in the same boat as the other short zooms. I’ll be looking forward to getting my hands on this little bad boy from Angenieux and putting it through the paces. I have no doubt I won’t be let down.

Canon PL Zooms

Canon PL Zooms

Canon is releasing a couple of PL mount zoom lenses. Some might think this is a step in a new direction for Canon but they had great success with their 16 format zooms back in the late 80’s in the form of a 11-165mm and 8-64mm that were based on some of their popular video lenses.The optics and core mechanics were transplanted into a cinema friendly housing. The lenses worked great and performed very well. You can still find them floating around rental houses and private owners basements since they only cover a very small 16mm film format.

Canon's previous 11-165mm S-16mm lens.

Canon’s new lenses will be native PL mount and will cover an image circle of 27.5mm which includes APS-C sensors. The RED One requires an image circle of 28mm so you’re pushing it there… It certainly won’t cover the Epic camera with a required 33.5mm image circle. I would be willing to bet the telephoto of the two would have a larger image circle as is the case with most lenses. The focal lengths are going to be 14.5-60mm T2.6 and a 30-300mm T2.9-3.7. The 14.5-60mm size will be a little smaller than an Angenieux 17-80mm but larger than I would care to hand hold. T2.6 is a nice aperture for the smaller zoom but the 30-300mm will ramp and nobody likes a zoom that ramps. 🙁

If these two zooms are similar to Canon’s previous lens ventures, then they should perform very well optically and mechanically. I look forward to seeing these pups at NAB and bench testing them when they come to market. Good luck, Canon!

Nice Try, Sony

Nice Try, Sony

Everyone is raving about the new breed of “large sensor” video cameras most popular of which is the Sony PMW-F3 and it’s super 35 size chip. Shortly after Sony dropped news of it’s new intermediate camera they announced the specs for a set of three budget lenses that could be paired with the camera. The set of three lenses retails for about $5,000 (I think) which makes each lens a little over $1,500. That’s cheap! That’s pretty much the same price as a still photography lens. I waited for Sony to release actual production lenses rather than request press models that could have been tweaked for optimal performance.

A camcorder lens?

I came across a couple sets after a few months and had a chance to bench test them optically and get an idea of the general feel of the lenses. The first thing that caught my attention was the size of the lenses. Each lens is a little over five inches in diameter so I figured it would weigh a decent amount, but I was wrong. They’re actually not very heavy at all. Probably because they’re PLASTIC! Every external piece of the lens other than the mount is made of plastic.

Here's an example of the plastic corrosion from acetone. I tested it on the inside of a housing ring by rubbing a cotton swap soaked in acetone. The external does have a clear coat that helps, but still... Plastic?!?

Okay fine, maybe it’s the new, cheaper, modern way to make lenses and pass the savings onto the consumer, I’m down. But then I took one apart for funsies and realized Sony didn’t put any effort into these lenses at all. While I was taking the lens apart I came across so many things that rubbed me the wrong way like the plastic all over the place, the screws didn’t line up with their holes and were stripped before I even touched them. Not a big deal, I’ll just use a bit of acetone to dissolve the glue around the head. Nope! The plastic housing is not chemical resistant and acetone will simply melt the plastic and bond the screw even more. That’s okay, I have other methods for removing stuck screws, like heating them up to melt the glue. No, again! A single hit from my torch would turn the plastic housing of the lens into a blob of resin.

Difficult to tell from the photo, but this screw is inserted and tightened at an angle and then covered in glue. No acetone or heating help here. I'm pretty sure the small ring next to the screw is where the hole was supposed to be drilled. Oops?

Granted most of these problems are from a service standpoint. There are certainly fewer user issues than service issues, like the lack of critical focus marks and witness marks on each distance instead of just a number. Obviously this makes pulling focus difficult (or easy depending on how much you care about accuracy). As a user, you had better keep these lenses out of the dust and don’t even think about shooting at the beach. The housings are highly susceptible  to contamination (dust, dirt) leaving the focus and iris rotation gritty and uneven. And that gets me back to the service woes… In order to clean and lube a lens like this, the cost would be a little over half the value of the lens. That’s just not reasonable. I’m sure if you sent this back to Sony for service, they would send you a whole new lens and chuck the old one, common practice for consumer product service. Stick to TV’s and camcorders, Sony. You do great work there.

UPDATE:

I didn’t really go over the optics at all in my original post. But now that I’ve had a chance, I bench tested the lenses and they did perform decently. The optics are certainly not bad by any means. I would compare them to Zeiss Super Speeds. There is little to no light falloff at the edges and resolution is even from corner to corner. Breathing is present but minimal. To compare the Sony primes to existing primes would be difficult. Optically, I would say they fall between Ultra Primes and Super Speeds. These lenses will certainly get the job done. I may have been a bit harsh before… Nah.
