Anyone tried / have samples from arri-macro t3 lineup?

I know some of you out there have plenty of stuff available in your vicinity. I'm considering some of these for rental, but can't find any samples of how they look.

GH2/Bmcc anamorphic lens

raf702 — Tue, 17 Jun 2014 22:54:42 +0000

Hey all, I seem to have an issue in regards to my Isco anamorphic 2x lens. I have both a GH2 and a BMCC-EF, and when I use my Auto Chinon 35mm and Isco 2x I get no vignetting on the BMCC. BUT, on my GH2 with the same setup, I get very noticeable vignetting.

Any ideas, or reasons why this is happening? I want to use a wide prime on the GH2 with a 2x anamorphic without any vignetting.

I appreciate anyones help. Thanks!

Panasonic 20mm f/1.7, 14.5mm f/2.5 or Samyang 16mm f/2.0?

brant_moore — Mon, 09 Jun 2014 18:48:46 +0000

Does anyone have experience with all three of these lenses that can chime in on what might work best for me.

The lens I purchase will be for the gh4 and gh2 to be used in a factory setting as well as action sports on a daily basis. I need something wide and fast. Autofocus isn't a deal breaker so the Samyang isn't out just for its lack there of. Autofocus is nice, but if the Samyang is superior enough I can deal without it. I will also use this lens for interviews occasionally. Just looking for a professional opinion for a the best quality all around lens that is wide and fast.

Right now I have the 14-42mm, Samyang 7.5mm and a 50mm f/1.4 Nikon with adapter. Im trying to stick around 300-400$ and willing to buy another adapter, so if there is another lens in this area please bring it up.

Thanks in advance for any help!

Source for replacement parts for Rokinon 85mm Cine?

Sangye — Thu, 29 May 2014 12:40:54 +0000

So I bought a Rokinon 85mm Cine for Nikon on eBay last year for an absurdly low price, but it has a broken aperture mechanism. The internal components work fine, but the mechanism that connects the aperture to the external control on the rear element, as well as to the actual aperture ring, are broken. When I got it the aperture ring and rear aperture control worked, but it wouldn't open past around f/2.8. After taking it apart and tinkering with it, I got it to stay open at f/1.4, but in the process I lost control through the aperture ring, and can only adjust it by taking the lens off and manually moving the lever on the Nikon mount. I think some of the parts are bent, and the spring doesn't have enough tension to overcome that resistance and close the shutter back down again.

Basically, I need a new rear Nikon mount, and the parts to replace the mechanism that connects the rear mount to the internal aperture control rod / lever thing. My guess is it's the same parts as I would need, if I wanted to convert a 85mm Cine for Canon to Nikon. Just the parts that have to do with Nikon.

People here seem pretty clever, and savvy to sources for obscure asian camera technologies, direct from the manufacturers. Wondering, if anyone happens to know where I could find these replacement parts? Google hasn't turned up anything yet.

Canon EF 16-35mm f/2.8 front element problems

bonini12 — Sat, 24 May 2014 11:24:56 +0000

Hello all.

Recently I bought a second-hand Canon EF 16-35mm f/2.8 L USM (Mk1). I could see it was pretty much used, but the image quality and sharpness seemed OK, and the price was good. Well, I could see some semi-transparent specks on the front element, but I thought they were stains of some kind that will go off with the cleaning. And even if they don't - I thought - some front element blamishes should not effect the image quality... Unfortunately, I was wrong in both.

R.O.R. doesn't clean the specks, nor isopropyl alcohol, not even acetone (used carefully on the spot).

Do the specs affect the images? Well, yes. Especially in high contrast situations, and against strong sources of light there's much light dispersion and even light stains visible around light sources or objects reflecting strong light. This makes the lens practically useless for night photography, as the light helos/stains around street lamps etc. are just too strong.

In normal or low contrast, the stains become visible only when stopped down to F10-11 or more.

Is there anything I can do for this lens? Is it possible that the AR coating might be peeling off in those places? Could it look like that? Otherwise the lens is OK - the rear element and the inner elements (judging by a thorough inspection with a torch) seem totally OK, the images come out very sharp and all the mecanisms (AF, zoom, etc.) work fine.

========================================

Another problem is that there's some light dispersion overall ("softness", but not related to sharpness), visible at 100% magnification - not only where the stains are, but around any lit objects. Could this be related to quite a bit of dust particles visible behind the front element when I pass through the torch light? I unscrewed the plastic lid around the front element (by 2 little holes in it) to clean the front element, but - unlike with other lenses, the front element doesn't come out easily. Looks like it's hold by 3 locks that I marked on the 3rd pic. Any suggestion to how to open the locks?

I've read somewhere that after removing the front element on this lens, it needs recalibrating. Is it true, and is it possible to do at home?

Please have a look at the pics: http://s1273.photobucket.com/user/bonini12/media/_MG_8005-2_zps90d4ca68.jpg.html?sort=6&o=0

Hi. Sorry for this question, especially if it looks stupid, but I'm a total new comer to DSLRs and mirrorless cameras. I'm about to buy a used Sigma lens (50-150mmwhich works usually on asp-c sensors. But I would like to know if it works correctly with a on a Lumix GH2 with the Nikon F/G - m43 0.71x. speedbooster/adapter (sold on this forum) ?

A good and not very expensive wide lens for M4/3: my two main candidates

Manu4Vendetta — Tue, 20 May 2014 12:47:45 +0000

Actually I have the Lumix 14mm 2.5, great for the price basically for still, in video I dont like much.

Im thinking between the SLR Magig 12mm T1.6 Built-in Lens Gear and the Tokina 11-16mm f2.8 for video (adapting), I will make the upgrade to GH4. I think it's the best around U$500, I dont see better options.

The Zuiko 12mm its good for still, but more expensive. The Rokinon have little tests and dont speak so well.

Suggestions?

Hasselblad lens

FS: Swapping Speed Booster MFT against Speed Booster BMPC

cantsin — Thu, 15 May 2014 02:21:08 +0000

Swapping an eight months old Metabones Speed Booster Nikon-to-Micro Four Thirds (usable on any Micro Four Thirds camera including GH2/3/4) against a copy of the Metabones Speed Booster BMPC for the Blackmagic Pocket Cinema Camera. My copy was directly ordered and bought from Metabones.

This might be an interesting deal for people switching from the BM Pocket to the GH4.

Conditions: Speed Booster copy must be in the same good state as mine (no damages/scratches on glass, practically as good as new), only swapping with people in the EU (ideally in the Netherlands).

If you are interested, please drop me a personal message!

Does APS-C glass vignette on GH2 + Speedbooster?

Sangye — Sun, 17 Nov 2013 22:12:26 +0000

I just sold my Voigtlander and ordered a Nikon-MFT Speedbooster, and am planning on buying a Sigma 18-35mm f/1.8 to use with it. However, I just ran the math and am a little confused.

If the crop factor on the GH2 is 1.86, and the MBSB effectively reduces the crop factor by 0.71, then the new virtual crop factor should be 1.86*0.71 = 1.32. 1.32 is more like APS-H size, not APS-C. Doesn't that mean APS-C glass will vignette?

Another way to look at it would be to begin with the Nikon APS-C crop size, 1.5, and divide it by the MBSB coefficient, 0.71. This returns 2.11. If my math and my understanding is correct, that's the maximum sensor size, expressed as a crop factor of full frame, that a APS-C Lens with a Speedbooster should cover. So it should cover the BMCC, but not the GH2.

Am I thinking about this right, and will I encounter significant vignetting if I tack an 18-35 with a MBSB onto my GH2?

Gh2 , lenses

jclmedia — Thu, 08 May 2014 15:27:42 +0000

So Im going to sell my gh2 and my hpx170 so that I can afford the new gh4 $1699. I have a 14-140mm kit lens That I bought with the gh2 and the 7.5mm ronkinon fisheye. I def. want to keep the fisheye for my gh4, as for the 14-140mm Im not sure yet, Because I really like the 12-35mm 2.8 lens but then it would be around $2400 for everything. any recommendations?

Thanks

Lumix zooms vs Nikkor primes

SuperSet — Wed, 07 May 2014 00:15:15 +0000

Hey fellas - Can anyone chime in on why the Lumix zooms (i.e. 12-35mm, 35-100mm) are considered more 'video-ish' than something like the Nikkor primes (20mm AIS)? I usually turn down the sharpness anyways for Lumix zooms so shouldn't 20mm on a Lumix 12-35mm look just as good as a Nikkor 20mm AIS?

Lens for shooting the moon?

tonalt — Mon, 21 Apr 2014 12:11:04 +0000

I'm going to video shoot moon and need good tele lens for that. It needs to be sharp as possible, but not too expensive. Since I have m4/3 cameras I could try some older vintage lens with m4/3 adapter. And I also need to get as close as possible to the moon.

Any recommendations? Aperture doesn't matter that much since moon is so bright.

Nikon AI(S) vs Canon FD for Video (GH2, GH1)?

qwerty123 — Thu, 14 Jul 2011 22:18:06 +0000

While there is some stuff about comparing these two lens lines regarding photography, has anyone done any comparisons between these two lens sets for video, specifically, the Gh2 (or gh1)?

The pricing of these lenses seems to be getting closer by the day (FDs seemed to be cheaper a few years ago). But apart from the way the focus turns, is there much of a difference between these lens lines for video work?

Specifically, I'm interested in IMAGE QUALITY / DIFFERENCES.

I've heard some people say they like the contrast and rendition of Canon FDs (Hunter Richards, I think), and that Canons tend to be a little "warmer" in color than Nikons. Wouldn't white balancing cancel out that effect?

(I know that there is the L series of FD... but we can leave that issue to the side unless you think it is important.)

Fujinon A20x8.6BERM Lens - Micro 4/3 compatible?

Timx98 — Fri, 11 Apr 2014 06:51:37 +0000

***EDIT: I was not searching for the right terms online. This is ENG lens and it has been successfully mounted to DSLRS with numerous tutorials. Please disregard. ***

I have several Fujinon A20x8.6BERM lenses from a Sony Digital Video Camera DXC-D35.

I've searched the net to see how well this lens would work on my GH3 with an adapter but cannot find anything.

Here are the specs on the Lens according to: http://www.fujifilmusa.com/products/optical_devices/broadcast-hd-sd/sdtv-lenses/2-3-pro/a20x86-berm/

Note: It says the aspect ratio of the lens is 4:3...Can a lens be set for that? I thought that was determined by the camera recording format, not the lens. (my apologizes for the noob question. I'm still learning).

What are your thoughts on this lens for micro four third use? Would I be able to set up an external power supply on my rig to use the zoom feature?

Speed Booster or Native MFT Lenses?

Kokav — Thu, 03 Apr 2014 15:01:04 +0000

I have a GH2. I primarily do video. I have three native MFT lenses: Panasonic 25mm f/1.4, 14mm f/2.5, and 14-140mm f/4.0-5.6. I have done a lot of searching about the Metabones Speed Booster but want some confirmation if I should go ahead and get one. I really like Nikkor AIS lenses and am wondering if it would be wise to invest in a set of AIS lenses (and possibly some others) and a Speed Booster rather than more native MFT glass.

The reasons I want the Speed Booster are pretty obvious: extra stop of light, wider viewing angle... But I want to know if it's really worth it. Will it actually make my lenses look better? I really want to know what the downsides are. Are there GH2/3 shooters who use the Speed Booster exclusively?

I'd really appreciate any pointers or discussion on this.

Dog Schidt Lenses

shian — Tue, 08 Oct 2013 15:58:59 +0000

So over at a friend's house borrowing some lenses and he asked me If I had used any dogshit lenses lately. I laughed and said, "I really try not to ever use any", and then he showed me what he was talking about. The name alone made me laugh, but the results are kinda awesome, and I like what these guys are doing. For Cameras with shallow DR, these are amazing lenses.

I just love that their contrast options are "Low, Lower, and Stupidly Low."

Using focal reducers with GH1/2 and old lenses?

Psyco — Wed, 03 Aug 2011 15:24:12 +0000

Hi!

As I dont like the result of using wide angle adapters and it is not easy to find cheap bright and wide lenses, I did some tests with a focal reducer.

The idea is, to use the much bigger image circle of the full frame lenses and squeeze it onto the m4/3 sensor. As a result this would give more light and more angle of view. As there is enough space between the backend of the lens and the image sensore, it would be possible to modify this cheap adapters (like Nikon/Canon/.. to m4/3 adapters you find on ebay) to fit a focal reducer in it. This would not only set the angle of view back to what you will get on a full frame DSLR, but also brighten the image by the same factor!

After some testing with my GH13, Antares 0.5x 2" focal reducer and Minolta MD Rokkor-X 50mm f1:1.4 ...

Test Image without reducer at high F-stop (sorry for the boring subject;-):

Same lens, high F-stop, same setup but WITH focal reducer:

Obviously, the field of view is wider - just not as much as I like it to be. But a "stronger" focal reducer might solve that problem. The image is also brighter - in this case I used a different shutter speed - which was pretty much what I expected.

But as we all know, high F-stops are not what we want. Same setup, same lens without focal reducer, but at F1.4:

And finally the lens at F1.4 WITH focal reducer:

Wider field of view, brighter image but horrible IQ. The white glow is known as coma (thanks to hopeless_4ever for that information).

There are also coma correctors out there, but there is not enough space between the lenses to fit one of these also in there.

Bitcrusher did some very interesting tests with the rear element of a Tokina lens. Hopeless_4ever also pointed out, that Olympus did reworked some lenses with focal reducers to fit m4/3 - so, it is possible.

These last bits of information point in a promising direction, but there is still a lot of things to test and think of.

If we could find a setup to project the full frame image circle in good quality onto the m4/3 sensor, we wouldn't need the crop mode on the GH2 and the tiny c-mount lenses or buy the very expensive m4/3 lenses...

...but the ultimate goal would be a 1.5x anamorphic focal reducer - small, not as expensive as a full lens and the choice of the main lens would still be up to us!

Hopefully someone has a good idea, as how to proceed from here. Focal reducers with stronger light bending exist, but without solving the coma-problem, that doesn't get us closer to something usefull.

35-100mm Panasonic vintage lens alternative

Sph1nxster — Wed, 15 May 2013 05:57:02 +0000

Looking for suggestions for a cheaper alternative to the 35-100 X lens from Panasonic.

So far I have looked at the 35-105 3:5 Canon FD, which is pretty close.

Is there anything better than this in any other mount?

M42 lenses for use with Kowa anamorphic lenses with BMPCC / GH2

burrencrawler — Sun, 30 Mar 2014 07:09:06 +0000

Hi Guys, This may be my first thread, I have a BMPCC and a GH2 both of which I love. Also recently I have bought a Kowa (sometimes labelled as Bell & Howell) anamorphic lens. This will be my first time playing with anamorphic, I love everything about the look. The Kowa anamorphic lens is a 58mm screw mount lens that needs a screw mount adapter kit which clamps on to your lens of choice. So far I have got the Helios 44-2 58mm, Focal MC F2.8 135mm, & a MIR-1B F2.8 37mm lens. These are all VERY reasonably priced on eBay. Has anyone any other ideas for must have M42 lenses for use with anamorphics with a BMPCC/GH2?

Samyang 16mm t2.2 cinelens

maranfilms — Thu, 27 Mar 2014 09:29:24 +0000

All shots were done with the Samyang (Rokinon) 16MM cine lens used on a G6. Great lens, little distortion, sharp with good contrast. This lens comes to life as most do around F4-8, but can be pushed either way and still produce a nice image. If your a m4/3rds shooter, I would go for it in that mount to do away with an adapter due to the size. This lens is smooth with a follow focus, although for this vid, I shot it stock, focus was all done in hand.

B4 lenses for event shoots?

kupchenpo — Mon, 10 Mar 2014 15:29:54 +0000

I have some event shoots coming up. Single speaker on a stage with two camera angles. Both cameras will be gh3s. I've rented a couple nikon 80-200mm for these in the past, they are cheap to rent, and really good lenses, but when I want to reframe I loose focus and when I need to change exposure, I have to do it in clicks. It seems that a good quality b4 lens adapted to m43 would do just the trick. The only thing is, I can't find any footage, other than bs test footage of random stuff. Or anyone talking about using these constructively. Has anyone out used these lenses for events or weddings with results they were happy with? With which specific lens? Or perhaps seen footage of that would make you lean either way? I'd want to use the one with a 2x extended, I never use extele unless it's not possible to get by without.

Thanks guys.
