    New To Sony

    It may only overheat if you're doing 4k video for extended duration. The Nex 7 can't film in 4k so it's not an issue there. The overheating issue has been adressed somewhat by allowing you to increase the shutdown temperature threshold. This doesn't harm your camera but may cause it to become hot to the touch.

    New To Sony

    Autofocus is better on the a6000 (phase/contrast detect instead of just contrast detect), continuous autofocus at 11fps burst vs 3fps on the nex7, it has a bigger buffer and better ISO performance. Only reason to get the old nex7 over the a6000 is if you want a mic port or like the old controls better. But you really want the a6300 then for just slightly more $. Long story short: don't get the nex7.

    Advice for A6000 Manual Focus

    That will work perfectly and is exactly what MR mode is intended for. Be sure to save all your settings to a memory profile: just changing settings while in MR-mode won't store them. Nothing of auto-mode is affected by your memory settings a.f.a.i.k.

    Filter system for Sony A9

    Since you posted this in the APS-C forum, you do realize that your A9 is in fact a fullframe camera?

    Next portrait lens for full body shots at close range.

    Sigma 16mm f/1.4 might just fit your budget, though I doubt such a wide focal length is useable for model shooting due to perspective distortion. But that's up to your artistic taste to decide. Another great option is the Sony Zeiss 24mm f/1.8, though that one is out of your budget.

    long exposure question

    I think I've found your solution: your ND filters are not 8 and 4 stops, but 3 and 2 stops respectively: to get the stop number, take the Nth root of the ND number, where the answer should be 2. So 8^(1/3) = 2 and 4^(1/2) = 2. Combined you only have 5 stops of ND, not 12. A correct exposure should then be 1/25 sec × 2^5 = 1.28 sec instead of 164 sec! The numbers on ND filters are designed such that you can easily calculate the correct exposure time. Don't think of a number of stops, just multiply everything: 1/25 sec × 8 × 4 = 1.28 sec. The MM+/- number is just a realtime exposure meter compared to a 'desired' value of 0. Point your camera somewhere dark or bright and you'll see this number go down and up. Nothing is compensated for, it's just a reading.

    long exposure question

    If you are in manual mode and have ISO set on 100, by definition can there be no auto exposure compensation by your camera: all three exposure variables are fixed by your manual settings. Your math is correct: if you meter 1/25sec at f/11 ISO 100, if you add 12 stops of ND the same exposure requires 164 seconds (or 2 mins 44 sec). Are you sure you stacked the two ND filters properly? Was your ISO fixed at 100 when you did the metering in A mode? Unlikely to be your problem as this would have caused under- instead of overexposure. Just trying to isolate your problem.
  8. The movie is not playing here so can't comment on your quality issues. Did you record in HD or 4k?

    Screen dims when shooting video

    Afaik this is done to reduce power consumption, and more importantly heat generation, by the camera. Especially when shooting 4k video this should increase the time until the camera shuts down due to overheating.
  10. You can set control over either aperture or shutter speed using the PASM dial on top. You can then control whichever you selected using the top right control wheel. No need to use the back dial if you don't like. You can't switch between aperture or shutter priority using any other button afaik (except maybe when you set your camera in Memory-mode and store A-mode under memory1 and S-mode under memory2. A lot of other stored settings will be set simultaneously tho).
  11. Care to tell a little more about your subjects and methods? Do you shoot events, family, intimate portraits, astro. Do you use a tripod after dark, do you mind longer exposures? Do you find your a5000 focusses acceptably fast in the dark, or do you resort to manual focus?
  12. I think it's the same for Sony camera's. You can use e.g. custom white balance or scene modes, the effects of which are applied to the jpeg but not to the raw file.

    Lens confusion...

    The article you quoted is wrong, there is only one 70-300 for e-mount. The DT they refer to is probably for a-mount, which can be used with an adapter. Another option is to use the Sigma 100-400 C with the mc11-adapter, but people report mixed opinions on the Sigma lenses with the mc11. Lets hope Sigma releases their new and cheap 100-400 in e-mount too as they did with all their recent art lenses: sure would be a winner as the only competition is the expensive 70-300 G and even twice as expensive 100-400 GM.

    Raw vs JPEG

    My point exactly Chrissie. A jpeg can be the same size as the original RAW (thus being uncompressed by your definition John) yet still tons of data is lost in the conversion process. The initial statement of 'extra fine jpeg is compressed approximately 2:1' therefore doesn't make sense: jpeg conversion isn't compression, it's just lossy conversion. Even if done at the same file size.

    Raw vs JPEG

    How should I read this then?
