Confusion Buying Video Lens for Sony a7iii

Recommended Posts

Hi Good day.
Sorry for a long post... I am messed up with too much info online, so seeking help from forum members...

I have bought Sony a7iii body, but totally confused with a video lens to choose (at present due to budget has to go for only 1 lens - any lens <$1000, better if less best)

Purpose of Usage is making Self Content (not for client): 

  • 50% Videos Shoot (Youtube Videos & Short Indie Films but good cinematic quality) 
  • 30% Vlogging Videos (Still with tripod in a room not travel handheld, buying external monitor to lookup)
  • 20% Still Photoshoot (For Thumbnails & Social Media Graphics)

#1 Most pref. i might need autofocus lens so non professional helper can use it to make my videos, if lets say i am anchoring/acting in video.
#2 Might use with DJI gimble in future, so not too long / heavy lens
#3 Confused with 50 mm vs 35 mm (as most videos will be indoor/rooms, so i think 35 better ?) any disadvantage of 35 over 50 ??? for full frame body
#4 With sony a7iii eye / face tracing autofocus, do we still opt for fixed cinelenses / prime still lenses ? Is focus breathing and light change a big issue in making videos ?
#5 What to choose Samyang cine 1.5  vs Sigma Art vs Sony G vs Other options ? Keeping in mind <$1000 range

A detailed suggestion will be wonderful and life saving...

God Bless...

PS: Have recently used a7s2 with Samyang Cine lens 1.5 - the output with proper led lights was decent / good, not out of the world... and sometime face out of focus
       (its a manual lens, too much time consuming retakes, espc if its time to time movement based / kids game / walking type)
       you know many time actors face/body move forward and backward while talking.... bokeh was okaish, as in rooms you really dont have much distance behind...

    • Hi, Last year I switched from Nikon to Sony (A7Cm2) and this situation surprised me in an unpleasant way. When I travel, I record rather short 8-30 seconds clips, a lot of such clips. And found that these files are rather big because of rounded up to the nearest ~32MB. Different SD cards (64GB) fill up very quickly because of that behavior. Sample sizes for different durations of those clips, for example I have 700 clips with these "distinctive" sizes +/-, nothing in between 33,592,255 67,149,921 100,706,705 134,367,160 167,821,451 201,378,823 234,936,491 268,594,590 302,050,059 335,709,042 ... and so on +/-1000 for the smaller files up to +/-100,000 for the bigger ones rounded up to the nearest ~32MB  Different 64GB cards were formatted inside the camera with exFAT (allocation unit size is 128KB) Why is that? Is there some setting for that?  -- Piotr
    • In short: AF micro adjustment isn't needed in mirrorless cameras, so the option is irrelevant. In DSLRs, the focus module is in a different light path than the photosensitive plane. Minuscule differences in the lengths of these paths can be compensated for with AF Micro adjustment. In mirrorless cameras, the photosensitive plane also contains the focus points. So whenever the camera detects proper focus acquisition, the focus is also exactly on the photosensitive plane. That is, until you use an LA-EA4 adapter to mount your 500mm f/4 onto your A1, which uses its own AF module instead of the cameras AF system. I would strongly advise against going this route: you'll have a state of the art camera with an insanely good AF system, and then you dismiss it 'in favour of' a very dated and compromised AF mechanism. Better try the LA-EA5 if you really want to keep using your old lens.   Edit: apparently autofocus doesn't even work with the LA-EA4 on the A1. https://support.d-imaging.sony.co.jp/www/cscs/accessories/compatibility.php?area=gb&lang=en&mdl=ILCE-1&cat=7
    • Hi Everyone !! I intend to move to Sony A1 from Sony A99 ii. I plan to continue to use the Sony F4 500 G lens (A mount lens) with an adapter on the Sony A1. However, I cannot find the menu option to do the AF Micro Adj in the Sony A1.  In the Sony A99ii it was under the AF3 menu.
