  1. Just tested resolution and moiré against old canon EOS 550D : http://www.frenchytech.com/blog35mm/?p=1959 I let you judge by yourself, but perceptual sharpness is night and day and moiré is almost gone. I think it's better than the 5D mk3 sold as no moiré vid cam..
  2. Tested this week end, the yongnuo adapter. don't buy it, as it does not support aperture control in movie mode, IS neither. Next test is Viltrox Mk2.
  3. sony APS-C sensor is a little bigger than canon APS-C, that's why 1,5X and 1,6X. Concerning vignetting, ask forumers, for myself i 'll test it next week. I THINK you won't notice it, but you are warned. 3 cheap canon electronic adapters : king, yongnuo, viltrox, (RJ ??)... some won't control all aperture values of some lenses, some won't boot the cam for some lenses...but it works for majority. Inside the adapter, there's electronic chipset, which may not support all lenses correctly. adapter with manual iris is shit , because iris must be inside the lens, not in his ass !! expect vignets, diffraction, etc...
  4. Mechanically speaking, as there is no mirror, the flange focal distance is super short, so in consequence you can mount practically every lenses on the E-Mount EXCEPT those for small captors like 4/3 (crop factor > 1,6x) . CROP factor is 1,5X on sony, so expect little vignetting with APS-C lenses from others (1,6X), correct me ? watch the TABS of this website : http://sonyalphalab.com/sony-alpha-and-nex-technology-camera-and-lens-tutorial-guides/lens-adapters/ With a manual lens and adapter you lose, powered zoom (although not on all sonys), information like distance on EVF, lens optical corrections, stabilization (except for some canon adapter ), Hybrid superfast AF, BUT YOU KEEP peaking feature, exposure, infinite focus. If your lense has an electric aperture, simple adapter or with manul iris integrated doesn't work correctly(you stay wide open or with the manual iris you are vignetting) So , to sumarize best to gore !! -E-mount (humm power zoom), hybrid AF, distance in EVF, optical correction...but these lens are certainly not the best on market (far from) -A-mout lenses with adapter (humm G series), hybrid AF conserved -canon EF with metabones , crop factor to 1,15X, 1F stop gain, exposure, slow AF (not in video) -canon EF- EFS lenses with cheaper electronic adapter (starting at 100$), you keep, aperture, IS, slow AF, crop factor 1,5X, exposure -full manual lenses (humm good ones inside) with manual iris, you have focus peaking to help, exposure. -electronic controlled iris lenses...bad bad -go to the site to see each particularities of each adapter Keep with you 2 elastics, just to minimize light leaks at adapter junction, thanks to china incredible mechanic dispersion in most of the available adapters...mdr
  5. For myself, i use dxomark to confirm empiric tests made by people like those in this forum. Often tests are finally pretty accurate regarding facts from dxomark. A digital cam is mainly based on his sensor + electronic treatment like cars are built around a motor + injection. Plus the lens. Dxomark rates all, perfect. it's an unified database. Practical. @quirky, dxomark rates a6000 right where it should be : behind pro dslr (especially for low light) and leading hybride and amateur dslr. You'll learn what it is twice sensitive in low light compared to the old eos 550D or the GX7. 1 EV better in dynamic range with the 2 old timers. Definitly this a 2014 good sensor for APS-C, perhaps the best at the moment. @dstilio, thanks for the info of using picture profil sunset, or portrait, though i'm not agree on lowering sharpness.. Concerning workflow, i've just received the baby yesterday, so tests are needed. But with sony AVCHD 2.0 xvYCC, you'll have to be sure your NLE understands it correctly. After, it's like in sound editor, or after effects, it's better to translate in 10bit if you're grading just to minimize treatment errors, and now that they introduce BT601, better to export to something universal and decoding yourself the full range. But simplier is better, if fcpx manages that full range in avchd let's feed it directly !!!
  6. About the a6000, it supports also APP, if sony sdk let developpers touch curves and others, why not having log curve in picture effect in the future ? could be powerful like ML for Canon in somehow. https://www.playmemoriescameraapps.com/portal/
  7. hello @nevelik, dxomark is your best friend : http://www.dxomark.com/Lenses/Ratings You will discover that e-mount lenses are not well rated. You can use your canon lenses via metabones (~400$), but AF will be soso, and you'll lose some functionality. You have also cheap adapter (~100$), but it's mainly for EF-S lenses, because there's no lens in it to get 1.16X crop factor from metabones.(you get a bonus 1 f also). In digital photo, everyone should be aware that there's a strong link between sensor and lens. For example got a tamron 18-270, and with dxomark i'll discover that it's perceptual MPIX is below 6 MPIX in some focals, behind a 24 MPIX sensor !! hic, it's jam for pigs. http://www.dxomark.com/Lenses/Tamron/AF-18-270mm-f-3.5-6.3-Di-II-VC-LD-Aspherical-IF-Macro-Canon-mounted-on-Canon-EOS-700D---Measurements__870 In video, we are talking of 2MPIX for 1080p, so even your grandpa zenith will be fine, even if sony seems to read all pixels and then scale down to 1080, so better lens, give better 1080.
  8. Someone must confirm , but with metabones on the a6000, AF in photo is slow, and not useable in video mode. Because of phase detection not compatible with canon lenses i think. At contrary 6D is way better in photo mode particularly in low light mode and support to FF lenses , it's a FF, but in video you are near a 5Dmk2 except the codec which is AVC intra. Expect moiré, aliasing, difficulty to focus. http://www.focus-numerique.com/test-1566/reflex-canon-6d-mode-video-17.html http://www.dxomark.com/Cameras/Compare/Side-by-side/Sony-A6000-versus-Canon-EOS-6D___942_836
  9. reading the specs from sony a6000 movie mode : Movie: xvYCC standard (x.v.Colorâ„¢ when connected via HDMI cable) Compatible with TRILUMINOSâ„¢ color 2 questions: i don't see any differences between xvYCC and xvcolor !!?? So HDMI and AVCHD are 8bit 420 (422 ?) , and perhaps HDMI is not compressed in AVCHD, but not sure ? secand, the workflow in editor ?? instead of the rec 709 16-235 values for luminance and color, sony gives you the 1-254 values possible for luminance and color. that's why people say they recover data from highlights (and blacks too). So in FCPX, Adobe premiere, AE, avid, is this extra gamut managed when importing your file ? Not sure and else, you have to tweak manually the curves !!! It is only for editing, because if you don't have a bravia (xvcolor), or if it is for internet, you'll have to export to SRGB. I think the simplest is converting with 5DTORGB to PRORES or DNXHD with 601 import profile, so that the NLE can't confuse color space. Even playing directly the avchd file on your computer can not be accurate. weird. See this thread : '?do=embed' frameborder='0' data-embedContent>>
  10. Hello, guys thanks for all the tests. for myself, it's simply the best APS-C sensor for video, a 2014 brand new one helped with excellent electronic treatment from Bionz X. Order has been sent, receiving it tomorrow. Apart from that, specialists from french photo magazine (chasseurs d'images) tested it and this what they discovered from their lab : -autofocus is fantastic , but fails at 12m when a 50km/h object approaches, compared to 4m for pro DSLR. -noise reduction is set to high by sony, a balanced choice would be setting it to "LOW" -till 3200 iso , fine textures are well preserved -sharpness 0 setting is under normal rating compared to other dslr, even +3 setting stays under that they call 0 sharpness. So don't hesitate to be at max. They say, pictures are still extremelly crisp even at 0 sony setting, so post sharpening is recommended anyway AND possible. -contrast is not perfect. Highlights are soft, greys are between soft and normal, and blacks are between normal and strong. so we have a problem with transition between grey and black. So use a profile to minimize that ? -DRO mode seems to raise blacks although it should lower highlights, they advise to set to it OFF Now regarding DXOmark, it's a pity to see that none of the sony lenses has got high MPix render. this baby shoud be tested with the sigma 50mm f1.4 HSM A or canon 35mm f2 to see what's in the belly.
