Video-Friendly Lenses for Lumix DSLRs

LPowell — Mon, 05 Sep 2011 14:46:59 -0400

Although a wide variety of lenses can be adapted for use with Lumix DSLRs, most still photography lenses have subtle drawbacks that make them less suitable for video shooting, regardless of the quality of the images they can capture. In order to shoot consistent, production-quality footage, it's often desirable to mount a DSLR and lens on a rig that provides traditional movie camera features:

* Stabilization and control of camera movement
* Matte box shading of camera lens
* Direct, tactile control of lens aperture
* Follow focus control of lens focus

Lenses that adapt well to these requirements will possess a combination of subtle features that are often omitted from manufacturers' data sheets and overlooked in published reviews. While vintage lenses provide full manual controls, their compact, old-school design often makes them unsuitable for use on a rig. At the other extreme, modern trends in auto-focus lens design have eliminated a number of manual lens features that remain essential to videographers. In many cases, the most usable lenses for video come from early generations of auto-focus lenses that combined vintage manual controls with modern lens design.

Here's my list of features that make a lens video-friendly:

* Manual aperture ring
* Direct-coupled focus ring
* Proper focus ring rotation
* Non-rotating outer barrel (internal focus)
* Non-extending outer barrel (internal zoom/focus)
* Constant field of view
* Constant f-stop aperture
* Rotational zoom ring

While few lenses possess all the above features, a good video lens will make up for any deficiencies with solid performance in other aspects.

* Manual aperture ring

Lenses that lack a manual aperture ring are problematic for video.

Vintage manual-focus lenses all have manual aperture rings, and most can be set to an auto-iris mode for in-camera control of aperture in shutter-priority mode. Many auto-focus lenses have eliminated the manual aperture ring, relying entirely on camera controls to set aperture in manual mode. This includes all Lumix, Zuiko Digital, Canon EOS, and Nikon G-type auto-focus lenses, as well as most currently manufactured lenses by Tokina, Tamron, and Sigma.

* Direct-coupled focus ring

Lenses with an electronic focus ring are problematic for video.

While all auto-focus lenses can be manually focused, not all of them are truly manual. The focus rings on Lumix, Zuiko Digital, and many Sigma HSM lenses are not directly coupled to the lens' internal focusing mechanisms. As a result, their focus rings continue to rotate uselessly beyond max and min focus limits. Lenses like this cannot be used on rigs with follow focus attachments, since focus ring position is completely uncalibrated.

* Proper focus ring rotation

Lenses with contrary focus ring rotation are problematic for video.

When mounted on a rig with a follow focus attachment, the focus ring rotation of the lens will determine the rotation direction of the follow focus wheel. Regardless of which side of the lens the FF wheel is mounted on, it's important that focus-pulling direction be consistent among all lenses used on the rig.

With Lumix, Zuiko, EOS, and Sigma lenses, infinity focus is at the counter-clockwise end of focus ring rotation. With Nikon and Pentax lenses, infinity focus is at the clockwise end of focus ring rotation. Tokina, Tamron, and Samyang/Rokinon lenses are usually built with the appropriate focus ring rotation for each type of lens mount. Sigma lenses, however, always rotate in the Lumix direction, regardless of the lens mount. For follow focus use, I prefer lenses that rotate in the Nikon direction because it pulls focus closer as I rotate the FF wheel toward me.

* Non-extending outer barrel

Lenses with an extending outer barrel are problematic for video.

Most zoom lenses, both manual and auto-focus, are designed with outer lens barrels that extend when the lens is zoomed and/or focused. While the barrels on most vintage prime lenses do not rotate, they usually extend when focused. A lens whose length changes can be awkward to use on a rig with a matte box.

* Non-rotating outer barrel

Lenses with a rotating outer barrel are problematic for video.

Most vintage zoom lenses are built with the focus ring on the outer lens barrel. This causes any attached lens filter to rotate as the lens is focused, making these lenses unsuitable for use with polarizer and anamorphic attachments. Most modern auto-focus lenses use internal focusing mechanisms that avoid these issues.

* Constant field of view

Lenses that breathe noticeably while focusing are problematic for video.

The focal length of almost all lenses will change slightly as the lens is focused. This effect, known as "lens breathing", alters the framing of a shot when pulling focus, making the lens appear to zoom as well as shift focus. This can ruin a shot if it is noticeable enough to be distracting.

* Constant f-stop aperture

Lenses with variable f-stops are problematic for video.

On many zoom lenses, the actual aperture will vary when the lens is set at its widest f-stops. This will cause zooming at wide f-stops to visibly affect exposure settings, which can ruin a video clip.

* Rotational zoom ring

Lenses with push-pull zoom rings are problematic for video.

Virtually all modern zoom lenses use individual focus and zoom rings. Many vintage zoom lenses were designed with a combined zoom/focus ring which zooms by sliding along the length of the lens barrel. Lenses like this are usually impractical to use on rigs with follow focus attachments.

In the next post I've reviewed a list of video-friendly manual-focus lenses that I've found well-suited for use with Lumix DSLRs. In addition, you can find a list of auto-focus zoom lenses for Lumix DSLRs at the following link:

14-140mm lens usage

alcomposer — Wed, 28 Sep 2011 03:25:27 -0400

Hi,

I am sure that there is a topic here about this- however I can't find it after searching half the day.

I am wanting to know if the 14-140mm standard zoom lens is good for matte box usage etc... if not is there another lens? I mainly (only) use primes, so zoom would be just for documentary work. (so auto focus needed for run and gun)

Please let me know your thoughts, lots of guys on PV don't really have much nice to say regarding the 14-140, I have also used it and it is quite slow... :(

Thanks in advance...
@VK if you can find the thread that details this please take the liberty to post and close topic.

Lumix 14-140mm AFS problem

WarLightUK — Sat, 15 Jun 2013 15:45:34 -0400

Hi everybody,

I meant to ask this for a long time but kept forgting about it.

My 14-140mm Lumix lens is not behaving itself in AFS mode on my GH2. It just can not focus. It is working fine with GH1, it is working fine in AFC mode. But won't work with GH2. No other lens have this issue on GH2 so I don't think it is a camera body issue.

I don't use Auto Focus for filming and rarely use it for stills anyway but it is an annoying issue when you need it...

Anybody had a similar problem? Any thoughts?

Thanks a lot

Reducing the GH2's sharpness on the 14-140mm kit lens

TruHype — Mon, 25 Feb 2013 14:49:33 -0500

Hi,

I own the GH2 with the 14-140mm Lumix lens, and I just started making films. I really like the 14-140mm, it has a very fast autofocus (for filming skateboard or whatever...), and when zoomed in it has a very nice DOF. But the problem is, it is way too sharp (even with sharpness at -2 and the Apocalypse Now DrewNet 'Soft' hack 444 matrix). I bought the GH2 thinking that it would have the same "Smooth" effect as the Canon T2i, 7D, 5D but with more resolution... because the GH2 IS a DLSR (or should I say DSLM). I know I could have this effect if I use non-panasonic or vintage lenses, but right know I own only the Lumix 14-140, and I'm not buying new lenses right now (or anamorphic adapters). The videos with those kit lens looks too much like a cheep Hi-rez camcorder and not like a DSLR or Cinematic or RED video... I know, I know, I should use a short DOF, reduce everything to -2... bla bla bla... But the 14-140 is still too sharp. It maybe even look a tad better on the GH1...

Now is there any type of HACK made especially for that type of lens, or any HACK that really softens the image down (canon-like) without a big loss of quality ?

I've already tried "soft" hacks (apocalypse now...etc), but it doesn't change anything, the edges are still too rough and sharp.

I would like that kind of soft light and professional effect from Canon cameras (but with better quality) :

And not this too sharp/camcorder look effect (even though it's a cool video) :

But the best would be this effect (those are NOT Lumix lenses) :

(And yes, I like parkour)

I know that there are already some posts that are about the same, but none of them really helps me.

Please help me !

Harvey.

Most wanted ANAMORPHIC lens

slrmagic — Tue, 04 Sep 2012 15:35:25 -0400

Dear All,

We have received 4 email requests from members of this forum on the possibility of designing an Anamorphic lens. We had this thought for the past year and did a lot of research. There is one common request which is to have horizontal flares. The others requests did not have any common grounds. We came up with an idea for a 25mm f/3.2 1.35x or 35mm f/3.2 1.35x Anamorphic lens for micro four thirds. Shooting at 16:9 would give a 2.40:1 anamorphic output. Just before we decided to go ahead with the project we had a second thought. 2 Years ago we asked openly on dpreview.com forum for what photographers wanted and the general consensus was our SLR Magic HyperPrime 12mm T1.6 lens.

http://forums.dpreview.com/forums/read.asp?forum=1041&message=36104678

It did not fulfill the needs and wants of everyone but we made what most people agreed on by means of a discussion. It ended up being a popular lens that we still are having problems meeting demand and we think it had a big part to do with asking photographers. If we did not ask around we probably made a 12mm f/2.8 lens. As it turned out quite well last time we want to make our next lens an open discussion again.

Here are some of the possible options we received and please feel free to throw in extra ideas. I hope people experienced with shooting in Anamorphic can also throw in ideas.

Anamorphic Adapter (1.33x, 1.5x, 1.75x, 2x) Dedicated mFT Anamorphic adapter for reasonable size Anamorphic adapter compatible with FF lenses 50mm f/2.8 Anamorphic lens (FF, APS-C, or mFT) Expected MSRP (Sad fact but it as direct correlation to IQ)

Kind rgds., SLR Magic Team

P.S. We will be at Photokina 2012 and would like to welcome any cinematographers with Anamorphic lens ideas to drop by our booth for idea exchange! We will be in Hall 3.1 B059

Anamorphic Pairing

UnTalGalvis — Fri, 03 May 2013 12:04:06 -0400

Well, hello there.

I've been studying Filmmaking for a year and a half now in Colombia and just recently bought a camera (A GH2). My lens collection is almost non existent, with only the 14-42 kit lens and an old Canon FD 50mm 1.8 ridden with fongus, and I'd like to start one.

Because of the look and overall feeling (Also, very rare in the indie/0 budget short film scene in my country) I'd like to go the anamorphic route. However, it is downright impossible to get an anamorphic lens here, so I don't have the chance to try one and then decide if I like it. I have to make those decisions online.

What I'd like to ask is what combinations of taking lens+Anamorphic has given you people the best results?

My two options right now are: Getting an SLR Magic Hyperprime 35mm T0.95 lens now and, after I get my savings account back in shape from that heavy blow, get an anarphic lens to use with it.

Or, getting one of the Dog Schidt lenses - https://www.facebook.com/DogSchidtOptiks?fref=ts -, which are much cheaper and have loads of character AND an anamorphic lens (With clamps, diopters and such)

Anyway, if there's already a thread like this, feel free to close this one up.

Thank you, guys.

Manual lens rebuilding

svart — Mon, 02 May 2011 15:53:54 -0400

Since this is a forum that is more about technical issues and I think the members are more interested in the inner workings of things, I wanted to share some information about lens rebuilding/cleaning.

Rebuilding/cleaning lenses is not a simple thing to do. The work is physically easy but any small slip up can render the lens unusable. Also, in most lenses if you take the helicals apart and then attempt to put them back together later, the helicals will line up a hundred different ways but only one way will be right. IF you take the helicals apart, be VERY sure that you have marked them somehow or you'll be in for a hard time.

I have been building up a set of manual nikon lenses, primarily AI series lenses. I've been buying cheap lenses that usually have stuck focuses since this is really an easy way to get lenses for less than premium price, as long as you can work on them. This isn't without potential issues as a lot of sellers will tell you the obvious problems but either won't know all of the details or they just won't tell you all the details. Some lenses have even been taken apart previously and put together wrong.. In short, there might be more problems with these lenses than you know about, so be prepared.

Anyway, I can't go into detail about how to rebuild a lens since each lens is different and might need different work done but I can share some of the issues I had.

One of the issues was re-greasing the lens helicals. Tons of websites and forums claim to have the magic formulas for helical grease or they'll tell you that some strange brand works the best. Some sell you tiny little amounts of grease for lots of money while others mention greases that haven't been available for decades.

I've tried a lot of different greases and here's what I found:

Forget any organic grease.

Anything marked NLGI 2 is going to be too thick. This includes pretty much any of the "bicycle" or automobile greases that are touted on a lot of lens websites. They make the lenses feel solid but focusing takes considerable force which may cause the lens to "bob" back and forth while focusing(also known as lens breathing) and/or shift in the mounts. Both of which ruin shots.

NLGI 1 is better but some of the greases are sticky while some are more jelly-like and offer very little metal-to-metal protection. Most of these are made to grease plastic gears or O-rings. A lot of these greases are PAO based oils with thickeners to make them more grease-like.

PAOs are the base chemicals for synthetic oils like Mobil 1 automobile oils. They tend to stick to metals pretty well and they never separate under heat and pressure like organic oils.

Many of the websites I read said nothing about using oils and the few that did said never to use oils. They never specified what kind or even if they had tried it. I found that synthetic motor oil felt the best and offered the most metal-to-metal protection in the helicals. I even performed a test where I heated the lens helicals up to see if the oil would run out. It did not, generally because synthetic oils actually thicken up slightly when heated.

I wanted a PAO based oil with a sticky property that had PTFE(teflon). I found Super Lube 51004. It's a high viscosity PAO based oil with PTFE. a few small dabs of oil on the helicals and the lenses move smoothly and easily with no "whispering" that you get with metal/metal contact. Just don't use too much, a small amount is all that is needed.

Image is blurring using GH2 body with Nikon 18-55mm AF-S

Cinematic m43 lenses

Manu4Vendetta — Mon, 28 Jan 2013 14:03:13 -0500

I'm saving to buy a good optical native M4/3. In the range angular to a maximum of 35mm. I have the pancakles 14mm 2.5 and the 20mm 1.7 but both some digital look.

My needs is lightness, quality and look, I do not like that look digital lenses.

At first I thought the Nokton 25mm 0.95 seems a superb lens, but I think it would have to last much saving, keep in mind that no cinema live, my investment is to make my short films that also costing my pocket and projects future.
The PanaLeica 25mm 1.4 lens seems interesting, but almost all the references I find are still photo and price does not seem so high. Does anyone have references to the?
The other option was the SLR Magic 35mm T1.4, but I read of problems for autofocus.
While I have read that the Samyang is not recommended.
I think SLR Magic comes with a 35mm and a 25mm both t0.95, but I think his price will be close to Nokton.

Thanks in advance!

Interested in peoples opinions on classic C Mount lenses in the sub 50mm region.

Currently looking at Zeiss, Kern, Berthiot

If you have some experience to share why not put it down here?

...and also any zooms you particularly like.

I'm looking to buy a Zoom lens for my Panasonic GH2 - that covers wide and medium focal lengths.

Which one do you guys recommend the most?
