Shooting with the Samsung NX500 - a pocket 4K cinema camera
TheRenaissanceMan replied to Andrew Reid's topic in Cameras
I haven't heard any complaints about battery life on the forums. No way to add USB mic, no mic input, the crop is inconvenient (though not crippling), time limit, no cinema profiles, no peaking during 4K, no EVF (compared to the A6000/GX7). The 120p/720 isn't bad actually, and they just recently put out a big firmware update. It's honestly a lot of compromises. If you're using it more for video than stills, I don't think it's worth it. Beautiful as that Samsung sensor is for RAW stills, the NX500 doesn't deliver it in video. Sadly. -
Sony has gone internal-4K crazy: A7RII, RX1004, RX10II

Those systems were never meant to work in tandem. Sony's OSS lenses are designed to work with 3 of the 5 axes of their IBIS. -
Canon 5D Mark IV "will be 1080p" with Canon LOG
TheRenaissanceMan replied to Andrew Reid's topic in Cameras
Actually, there's a lot of truth to that. Apparently, the Japanese love cool tones the way we love warm ones. That's why back in the day, they preferred Fuji's subdued color palette to Kodak's somewhat saccharine warmth. So in that regard, the Japanese most likely prefer Sony color the way so many of us in the States seem to love Canon. Honestly, if I were shooting video for clients, I'd use a Blackmagic camera in Video gamma anyway. An all-Prores workflow makes for quicker turnaround and better deliverables, and I have a very neutral starting point that I can tweak to the client's taste. -
Maybe not User Reviews, but I would love a subforum for buying and selling gear. Posting it with the news and discussions just seems awkward.

Canon 5D Mark IV "will be 1080p" with Canon LOG
TheRenaissanceMan replied to Andrew Reid's topic in Cameras
In what regard? Color is a wash. So is rolling shutter. DR favors Nikon. Canon's codecs are generally inefficient, so the file size to quality ratio won't be any better. Moire and aliasing is better on the D750 and D810 than any Canon DSLR besides the 1DC. Where exactly is Canon's advantage? -
Alright, can we all just agree that this is fake shitty footage and move on?
-
Fair enough! If you're invested in FD stuff already, an FD 50mm is your best bet. It's a beautiful lens and will match what you already have. However, it is not usable at f/1.4. At all. I tried it at a concert once, and the footage was lousy with purple halos. Completely unusable. The Rokkor 1.4/50 is much better wide open if that's how you're looking to shoot.
-
Not in my experience. I think they have a tiny screw to fine tune for infinity, though.
-
Nice stuff! How did the 10-bit out hold up in post? And how do you feel about the 50mm? Is it worth the money?
-
Ouch. Man, my luck must be amazing. None of the third party ebay products I've ever bought has given me a problem. It depends quite a bit on your shooting style, but I agree that there's nothing wrong with longer focal lengths for portraits and close-ups. In fact, it's my preferred method of achieving shallow focus, as that's the Hollywood method and the look most people are used to. I simply recommended the 25mm because it was the cheapest way to get cheaper and wider, which is what Fuzzynormal asked about. I'd prefer the 35mm or, better yet, the 50mm f/0.95. Pricey though.

I find specs are most useful in indicating the intent of the camera. When we saw the NX1's specs--4K video, H.265, high frame rates, manual control--it showed us that Samsung had put serious work into making a competitive hybrid camera. When we saw the Blackmagic Pocket's specs--no frills, RAW and ProRes recording, S16 sensor size, small form factor--we knew they wanted to make a small, affordable cinema camera. Marketing ties into this; Blackmagic wouldn't tout "13 stops of dynamic range" and "the look of real digital film" if they were making a consumer camera.

Wow, nice test! Parfocal (or close enough as makes no difference), very little breathing, and that great low-con FD look. I went with the 35-105, but now I'm considering replacing it with the 35-70. The 35-105's a nice lens and focuses relatively close but at the cost of being a fat as **** chunk of glass. Nice and fast on a speedbooster though, and that range can't be beat for run and gun. If you're looking for a shorter focal length with shallower DoF on M4/3, you might consider the 25mm f/0.95 from SLR Magic. It can be had for less than $500 used, it's incredibly well-built, and it has the nicest bokeh I've ever seen. A little low contrast and "glowy" at f/0.95, but better than the Voigtlander. It sharpens up nicely at f/1.4--and that's for stills. I happily use it wide open for 1080p video. If you'd like me to shoot some portrait tests for you, I can probably find some time later today if I can find a willing subject who isn't too hungover from 4th of July. In the meantime, here's a stills comparison against some vintage stuff and the Voigtlander. http://3d-kraft.com/index.php?option=com_content&view=article&id=137:adorable-25s-25mm-f095-speed-lens-comparison-on-lumix-gh3&catid=40:camerasandlenses&Itemid=2 If you want a longer focal length, SLR Magic offers a 35mm f/0.95 as well, and the 35mm f/1.4 has amazing bokeh too. Take a look at Flickr and see what you think. I'm a huge fan of these lenses for video, and recommend them to everyone shooting M4/3. Amazing bokeh, good sharpness, fast apertures, decent prices, and they have this inexplicable 3D look that's incredibly cinematic. It must have something to do with its sharpness characteristics combined with low global contrast, but it produces the closest rendering to actual PL cinema glass of anything in its market.

I've heard some horror stories about adapters and speed boosters for FD lenses. Luckily, I haven't experienced any problems with fotodiox or fotasy adapters, nor with my Roxsen speed booster. My advice would be to work gently, don't force anything, and contact the company for an exchange if anything isn't working to spec.
-
Haha, great to hear we're getting the same results! :) Can you elaborate more on what you're trying to accomplish in your landscape work, what tools you're using to expose, and how you're processing your files? Perhaps we can fine tune your method to help get you the results you want.
-
Here's the difference, Ebrahim. Some cameras apply that gain digitally, in software, and some apply it analog, on the sensor itself. Cinema cameras like RED and Blackmagic use digital gain for higher ISO's; stills cameras use analog.
-
ISO values on the Pocket have no bearing on its RAW files besides giving you a different preview. Of I'm incorrect, please provide a source that clarifies how and why.

Shooting with the Samsung NX500 - a pocket 4K cinema camera
TheRenaissanceMan replied to Andrew Reid's topic in Cameras
Totally agreed! The GH series has always had a very popular 1080p crop mode with excellent quality just in case you needed that reach, although the GH cameras could also use it for slapping small-format glass on there with no vignetting. -
If you want a vintage lens around 50mm that's sharp at f/1.4, my highest recommendation goes to the Minolta Rokkor-X 50mm f/1.4 PG. Sharp as a knife wide open, great color and contrast, but with slightly busier bokeh than its 58mm brother. That one is softer wide open--kind of a glowy, fairy tale look--but it crisps up by f/2 and the bokeh's much nicer. both can be had between $50 and $75, and can be stuck on a generic Speedbooster for extra bokehliciousness. Some of the Metabones SB shots I've seen have had busier/weirder bokeh than the lens on a straight adapter, but it's nothing huge if your base lens has nice OOF blur to begin with. Also, I must disagree with araucaria. There's no hard or fast rule on which focal lengths have the best bokeh because it differs wildly between different manufacturers' designs, and even between different designs by the same manufacturer! For example, Minolta's 85mm 1.7 has much smoother bokeh than the f/2. It's just something you'll have to research. Luckily, there's a ton of information available to those who know how to Google. ;) I wouldn't worry so much about the exact equivalent f-stop calculations on your lenses. Smaller formats don't scale exactly to their FF equivalent counterparts. They render differently. Lenses around f/1.4-f/2 in the 50-85mm range will give you beautiful, shallow portrait shots if you know how to use them.

Stacking adapters works just fine as long as you keep to the prescribed flange distance for that lens. If you have a Canon EF speedbooster on your micro four thirds mount, it is for all intents and purposes an EF mount and will work fine with any adapter that promises infinity focus on a Canon camera. As for the Roxsen Speedbooster, you're in luck! I actually own that exact Speedbooster for my FD glass. It's definitely not useless on an APS-C camera; in fact, I like using Speedboosters to get double the focal length choices from the same number of lenses. For example, if I have a 24mm and a 50mm, that gives me a 24mm (24 on the SB), a 35mm (24 with straight adapter), 50mm (50 on the SB), and 75mm (50 with straight adapter). More flexibility, less weight. It also just gives you another aesthetic choice with your lenses--do you want the S35 look, or the VistaVision/FF look? The Roxsen has performed fine in every situation I've used it in thus far. No issues with weird flare, strange bokeh, or softness on the edges. Just brighter, sharper, wider images. Then again, mine is for M4/3. You may get different results on the Sony.

Some cinema cameras, like the Bolex, Blackmagic, and Alexa, have only one native ISO. They use digital gain to "push" that data and produce brighter results for higher ISO values, but the RAW data never changes. It always captures at its native ISO on the sensor level. Some cameras, like all DSLRs/DSLMs, Canon's Cinema line, and the Panasonic Varicam 35, have more than one native ISO. They use analog gain on the sensor level to change the way the sensor actually "sees" photons, resulting in better dynamic range and noise characteristics at higher sensitivities. Hope that clarifies things.

GH4 with native lens vs G7 with speed booster +Sigma Lens
TheRenaissanceMan replied to Sanjimaster's topic in Cameras
Do you actually want to change lenses, or do you just want better quality and shallower depth of field? -
Shooting with the Samsung NX500 - a pocket 4K cinema camera
TheRenaissanceMan replied to Andrew Reid's topic in Cameras
Yes yes, I know you wish they'd kept that mode. But without knowing what roadblocks they ran into in implementing it, we can't really blame them for not putting it in the production model. Again, do you have a link to that? I checked a few places and got conflicting information--would love to see an official number from Samsung. -
Some good observations about the F3 and comparisons to the AF100, Red One, and Alexa. http://www.provideocoalition.com/ag-af100_and_pmw-f3_on_the_charts

TheRenaissanceMan replied to Andrew Reid's topic in Cameras
Source? What I've read says a 1.6x crop of the APS-C sensor. 1.5 * 1.6 = 2.4 Sadly, I don't think an NX->C-mount adapter is actually possible.
