I am dreaming.... maybe just to see the result.... of the Carl Zeiss LWZ.2 leightweightzoom lens on the GH2.... would just right cover my needs.. and allowances for the next 10 years... ;-) anybody tryed out on GH2?... mft mount should be available soon!?
I don't understand why people are saying that the Voigtlander 25mm doesn't work with a rig. I just shot the better part of a feature with the lens (on a hacked GH2), using a follow-focus and 4x4 filters in a matte box with no ergonomic problems at all.
Well..I cant use my 20mm pancake with my rig(I suppose follow focus to be precise) for sure...its just to close to the camera body and I don't have a reversible gear on my Fotga FF.
Personally I like using old M42 Lenses (screw mount) with the adapter. 1- They are cheap got a nice f/2.8 28mm on Ebay for 28 bucks... 2- They all reach out to the FF and have a focus stop point --yes they do move in and out but unlike the Panasonic lenses they use a mechanical focus so there is a clear end and beginning when you turn the ring. 3- There are fast lenses I've seen them ranging from 1.4 to 2.8 4- They look great, SUPER TAKUMAR 1:1.4/50 for example....
Nikkor 50/1.8 AIS - $35 Declicked aperture in a local shop while I wait 5-10 minutes - $12 Generic Chinese adjustable focus ring (haven't glued it on so I can replace it when it breaks) - $5 Generic Chinese 52-77mm step up ring - $2
Total= $54, did all of this during a lunch break.
Dulcos Cine Mod = $250 (without lens, shipping, lead-time, etc).
This is probably the best choice I've ever made in lens gear, the step-less aperture is so fucking smooth. I'm also going to do the same thing with my Nikkor 28/2 AIS - not quite ready to do this on the Nokton 25/0.95 just yet :-)

Thanks for the info on the Nikon 85mm f1.8D, I wasn't aware of its internal focusing mechanism, which it shares with the Nikon 85mm f1.4D. As you indicated above, this means that its outer lens barrel neither extends nor rotates. However, like all Nikkor lenses, it does have proper focus ring rotation in the Nikon direction.
Following up on @Brian202020's post, here is a list of video-friendly Nikkor AF-D primes from 85mm up to 300mm. In addition to possessing excellent optics, these lenses all employ internal focus designs with outer lens barrels that neither extend nor rotate. Unfortunately, this is not the case with Nikon AF-D lenses wider than 85mm - their lens barrels all extend when focusing on close objects. The lenses below all share the following properties:
Nikkor AF 85mm f/1.8 D Nikkor AF 85mm f/1.4 D Nikkor AF 105mm f/2 D Defocus Control Nikkor AF 135mm f/2 D Defocus Control Nikkor AF 180mm f/2.8 IF-ED Micro-Nikkor AF 200mm f/4 D ED Nikkor AF-S 300mm f/4 D IF-ED
The 105 and 135 DC Nikkors are my favorite portrait lenses on FX - gorgeous skin tones and unreal bokeh. Curious to see how they perform on GH2 and video in general.
I have trouble with EF-M43 adapters from eBay. I bought 3. Every zoom lens I attached after focusing and then I change zoom became out of focus. I tried Tokina 11-16, Canon 17-35. A metering ring also shows wrong value of distance. On Canon 5DmkII the lenses work precisely Now I'm waiting for another (4th) finally not cheap adapter - Kipon EF-M43 with aperture. I hope this one will be the right. I have thinking get rid Tokina, it was useless for me. I glad to read here that folks use zoom lens without problems. May be with Kipon adapter I will lucky.
I just got a helios 44-2 (58mm f2), and I love it so far. I heard that on these lenses oil on the aperture blades also isn't an issue, as many soviet lenses came from the factory that way. Anyways: Manual aperture ring: yes (very cool 2 ring system, allows you to open the lens and have a completely step less aperture if you wish) direct couple focus ring: yes proper focus ring rotation: counter-clockwise to infinity non-rotating outer barrel: yes non-extending outer barrel: no, extends about 1cm, maybe a little under (just from eyeballing it) constant field of view: no, appears to zoom out slightly when focussed towards infinity, thought I haven't tested this thoroughly
So, let's compare these to a set of cine primes... I use Lomo OCT-19 primes. Believe it or not, not even real cine primes perform 100% on this!
* Manual aperture ring: Yes and without click stops. * Direct-coupled focus ring: Of course. With distance marks that are correct. * Proper focus ring rotation: Counter-clockwise. * Non-rotating outer barrel (internal focus): Yes. The barrel does rotate when adjusting the aperature though (like on Zeiss Superspeeds). * Non-extending outer barrel (internal focus): No, same with Zeiss Superspeeds. The extension is very minor though. * Constant field of view: Yes.
As you see, while these are VERY video-friendly, even they lack some features. What you do gain however is: * Much better tightness between lens and adapter. Nothing loose here! * Large focus throw, for more precise focusing. * All marks are located on the side of the lens, allowing your AC (or you) to see them. * Correct distance marks. * Circular aperature. Bokeh won't be much different when stopping down. * Aperature in T-stops.
I'm curious what some good video-friendly lenses for the GH2 (or other lumix cams) would be ideal for a Duclos Cine-Mod.... interesting option.
Also @LPowell : can you be a bit more specific about the problem with a lens that has a focus ring that extends in relation to a mattebox? I'm a little new to learning about matteboxes.
@qwerty123: Leica R's would be a top contender. Great quality and no breathing! I didn't think I'd mind so much, but breathing has really become a deal breaker for me.
But personally, at that cost I'd just get some Lomos instead.
@qwerty123 A lens whose front barrel extends when either focusing or zooming can be awkward to use with a traditional, rail-mounted matte box. While a small amount of extension can be covered by a donut, an inch or more extension will collide with the back of the matte box.
@LPowell So in that case some legacy Nikon AI(s) and Canon FDs would be fine with respect to extension since they extend less than an inch when focusing.
I think two more ideal things in a lens would be: (1) LONG FOCUS THROW and, less importantly, (2) as @Gabel mentions, having the aperature in T-stops.
@alcomposer Depends on how well they work for you. Most manual-focus primes are relatively short and compact, with 52-55mm front filter threads. Using them with a follow focus and matte box on 15mm rails can be a tight fit. For my purposes, the Samyang/Rokinon f1.4 primes are a more convenient size.
