    Well, I thought I did some good research and yesterday bought the Kit A77 with the 16-50mm F2.8 lens. Not a pro/expert and don't know what jello-ing and aliasing are but most posts here are trashing the A77. Did I make a mistake? Does it suck?

  • hayhay

    @ alex

    agreed. i tested this camera and found the video quality sub par. i don't get it, particularly given the vid quality of the nex-7 - i would have thought the jello, aliasing and moire wouldn't be such a problem.

  • AlexAlex

    I Chose the flatest color profile on the A77. The highlight roll off is still not very smooth. Jello and aliasing are of the worst of all vdslrs. Non of these could be fixed by a firmware hack.

  • malamala

    I'm considering buying 6 of the A65's for my work which involves still and video capture of peoples heads inside a custom LED lighting dome..the captured images are used in photogrammetry software to build hi res 3d models.

    We need to capture the still images very fast so the A65s 10fps looks to be very handy…the draw back is the lack of tethered shooting, whist we can fire all the shutters via a custom board and the cameras remote socket, what we really need is control over camera settings and some sort of live view as well as saving files direct to PC…basically Breeze Systems but for the A65.

    If it was possible to extract higher video resolutions that would be a plus as well for our dynamic capture.

    So +1 for A65 Firmware hack…

  • lolodigitallolodigital

    Did some shots with my A65 ... DR is definitively more powerfull than GH2's . BUT low bitrate make video flat and not accurate for professional production ... Hacking A65/77 should be a great "new feature". A65 is nevertheless my best device for stills :-)

  • AlexAlex

    Did a quick test with a friends Sony A77. While the camera body and ergonomics are top notch (the EVF and the display are the best I have seen so far!), the video mode falls short of representing the next generation of video DSLR. 1080 60p is nice but it doesn't help if there is jello, aliasing, moire and artifacts all over the place.

  • BraceyBracey

    Have there been any attempts on hacking the alpha line? They have such great potential but are so crippled by Sony. I have extremely high hopes that there is some form of FW modification soon. I love the camera as it is, but am tempted to ditch my entire setup because the gh2 has it's hack, as does the canon line with magic lantern. I really hope Sony can receive the same type of love.

  • whoopteedoobuckaroowhoopteedoobuckaroo

    @Vitaliy, Ha! It didn't come out the way I meant it. I love my GF1, but the hacked GH1 footage I saw compelled me to buy one, too bad I didn't know about the firmware encryption at the time.

    What is even necessary quality-wise, is a matter of taste and venue for the most part. I for one really liked that movie shot with the Pentax K7, "Uncle Jack." I don't know how it would have looked on the big screen but for a web video, it is great, and probably most of us need to hone our ability to tell a good story using moving pictures, no matter how many pixels the camera has.

    Your hack obviously improved the GH1 and now the GH2, and I've never seen anybody go back to the original firmware. It also forced Panasonic to make improvements to, and push forward their release of the GH2. Your hack transformed the GH1 from a gadget to a professional tool. But I think the most powerful effect of the Ptools hack was psychological, not electronic.

    The Ptools hack opened my eyes, and others, to the fact that consumer cameras could be much more, freed from the limitations imposed on them by their makers. It is with a very cynical and limited view that these companies are approaching the new technology. Sony and Panny and everyone else should focus their attention on making the best cameras they can, not crippling their camera models based on the MSRP. I feel it is our duty, as consumers, to challenge this mindset, which is why I've donated equipment and money to you.

    I think that the Sony a65 is already a really fine camera, and a neat video tool. I know that if it's firmware were open, it would be a mind-blowing tool for filmmakers. it would also probably translate to the entire alpha line, and give you a great many new benchmarks to acheive. If you could squeeze 3860X2160 out of a sony, who knows what technology it would push ahead?

    @whoopteedoobuckaroo
    Let' be more sane. Many people shoot without any hacks and shoot wonderful footage.
    And many shoot on very good modern primes.
    7D and T3i are DSLR with ability to shoot narrative video.
    Huge amount of good films and clips ahd been made on them.
    But they have very big disadvantages.
  • whoopteedoobuckaroowhoopteedoobuckaroo
    I guess the flange distance of the GH1 gave it some benefits for legacy glass owners like me, but if Vitally hadn't jacked the firmware, it would have been a ho-hum camera, certainly nobody would've ever considered it a substitute for the 7d or even the T2i.

    When the slt a55 came out, I read some interview with somebody claiming to be tester13, talking about how imenantly hackable the a55 would be. I think the A77 & the A65 are prime candidates for hackage. There is enough good glass, it has fine IQ
  • whoopteedoobuckaroowhoopteedoobuckaroo
    From a historical film standpoint, the minolta glass is considered to be some of the best lower cost lenses out there. They, like Panasonic today, benefitted from their 80's collaborations with Leica, just as their teams were developing their AF Line, they were producing lenses that some say are up there with leica. It just seems like the bones of the SLT A-77 are good enough to deserve being freed from it's firmware.

    Uhhhgggg... Sony should get some professional movie/video maker to promote their camera than using the money to buy travel ticket and hotel rooms (press event in Greece, I am sure those reviewers will praise Sony camera). Filmed in 50p, mud mud mud codec breakup everywhere, aliasing. You can download the 1080p MTS image. Damn, I don't know if the guy use that part of the video because it is so fast that it might hide the aliasing (Form moire, I see a lot of purple on the water but I can't confirm it because it is smeared) but he achieved the contrary in another way.
  • bkmcwdbkmcwd
    α77 is a very interesting model.

    BTW, similarly, this α77 seems also to have the problem of heat though there were a lot of people who dislike problem of heat in Japan at the time of α55 and do not use it.

    Does not this become a problem so much in the areas other than Japan?

    Digital IS sucks. ILIS is the way to go. Like Power OIS. Or stable rig.
  • Vitaliy_KiselevVitaliy_Kiselev
    >Doesn't A77 use digital image stabilization for video?

    It looks so, so less sensor heating happens :-)
    Plus you get crop making FOV almost equal to GH2 :-)
  • stoneystoney
    Doesn't A77 use digital image stabilization for video?
  • mpgxsvcdmpgxsvcd
    The guy in that A77 review probably used 1080p @ 60 FPS for the video. However, he also encoded it to 1080i when he edited. It clearly has interlaced artifacts. Epic fail if you claim to be a video instructor.
  • Vitaliy_KiselevVitaliy_Kiselev
    Some opinions:


    As a current Olympus user, I can't help but feel the siren's call of this camera with its sensor that is twice the resolution of the current Olympus 4/3rds sensors and has 40% greater areal space. And then there's the magnesium-built body's environmental (dust and moisture) sealing and the new Sony DT 16-50mm constant f/2.8 with the same environmental sealing. Add the sensor-based image stabilization and dust-busting sensor shake, and on "paper" the Sony α77 makes a for a powerful replacement for both the Olympus E-3 and the E-5.

    But that's at first blush. Digging deeper and reading many of the pre-release reviews, I came across the Imaging Resource's review and this particular paragraph:

    From what we can tell, there is no strategy for keeping dust off the translucent mirror, except to blow the surface gently with air; it cannot be cleaned, and should never be touched. A fingerprint would require replacement at a service center.
    This is what I was afraid might be delivered. What use is an environmentally sealed body and lens when, by removing the lens and violating the totally sealed system, something happens to fall on the pellicle mirror that requires a trip to the service center? The Sony α77, at a suggested MSRP of $1,400 body only, is a bit too rich to have to send to a service center due to a wayward fingerprint, or any other contaminant that might wind up on the pellicle mirror. It may be that there's no danger, that this is a red herring, a false alarm. And then again, maybe not.

    So why do I think Sony gets it when everyone else is stuck at 2004? When I first picked up an Olympus EP-2 with the VF2 finder on it I knew I was looking at the future of professional digital cameras. Not because the EP-2 was so incredible (and for many reasons it was) but because the EVF was such a revelation. You could see what you'd really get. When you look through an optical finder you're seeing an image that's always at a wide open aperture setting, and it's beguiling with a narrow depth of field and a bright image. But a great EVF shows you what you're really going to end up with once you push the button. It's reading all the stuff you shoved in ROM and it's finessing the image exactly the way you requested. If you set a color balance manually it's showing you THAT color balance in the finder. No surprises. If you set f11 or f1.4 the EVF is showing you the exact DOF you'll end up with. The only two glitches were the shooting delay caused by moving mirrors and the fact that early EVF's sucked in low light. As the camera's files got darker and noisier so did the finder image. That was/is the Achille's heel of my beloved Sony R1......

    @DrDave

    Yes, pretty remarkable by Sony standards... and hey, it doesn't shoot to proprietary Sony media! Sony is just going crazy lately!
  • DrDaveDrDave
    I think Sony has made a remarkable achievement--they almost equaled a two year old cam, the Canon 5D Mk2. But hey, it is cheaper.

    My God those videos look disgusting... looks like Flip video or something. Of course, they are on an overcast cloudy day with crappy composition and boring subjects.
