Brother you cleared my all doubts
Thanks for information 😉
Here’s a trick as whenever I use the 16mm sigma on my A7IV, I’m always in FF mode in video. When you have “Active Stabilization On”, it does a slight crop image regardless what lens you use. That slight crop eliminates most of the Vignetting. In post, add a 8% crop to be exact and boom, a perfect clip with a final 19/20 mm field of view which looks amazing! Oh…& there’s also clear zoom too!
Exactly what i was thinking.
Also, in FF mode will you be able to use 1.4 or will it be 2.0 only?
@@TheSidwadhwa 1.4!
Also, if you don't wanna crop in post so that you can maintain a full 4k resolution clip, with Active Stabilization on, select Clear Image zoom & spin the cursor wheel 1 click to 1.1x's & boom, all the vignetting is gone! Then no need to crop at all still giving a 19mm field of view!

Glad you also mentioned the F/Stop is also x 1.5, and the MP count is 33 / (1.5 * 1.5), many people forget the square law. That's why I moved from A7III to A7IV, to get the 33MP for use with APS-C lenses as well as FF lenses.
Knowing all this, I grabbed the Sony APS-C 70-350mm G lens to pair with my A7 IV for travel. This with my full frame 24-105mm gives me a very versatile set up with just two lenses. The 70-350 is ultra light weight and produces spectacularly sharp 105- 525mm equivalent, 14.66 MB images which when scaled up to full frame size are excellent. Not up to my 200-600mm G lens, which is ludicrously heavy, but close.
As a person who is also trying to do this TH-cam thing all while working a regular full time job and trying to spend every spare moment with my family I appreciate all the work you put into this video. You definitely should have more subs. If 10 percent of the people that clicked on this video subbed to your channel you'd be in a better space.
Thank you. I am very confused about that. Now all doubts are clear & great content on your channel.
this videos sure clears up a lot of doubts I've carried about my sigma 16mm - thank you for being so thorough and detailed!
Glad it was helpful!
Great video! Thanks for sharing!
Very informative... Thanks alot ☺
Very good video! Thanks
Great video, thanks!
Also rolling shutter issue is fixed when using aps-c mode in a7iv🤗✌️
True 👍
Rolling shutter is also decent in 1080p full frame mode.
@@AlphaCentauri24 That uses binning right
@@AlphaCentauri24 10bit ?
Thank you men, you have relaxed me a lot.💪🏼
Very helpful, thank you.
Buen video, solo te faltó usar cleae image zoom con ese Sigma 16mm 1.4 para explicarle a tu audiencia como se le puede sacar más provecho a esa lente quedando aproximadamente un 18.5-19.5mm
Thank you for addressing this! Great video!
full frame and crop sensors explained nicely
best demonstration of the topic I've seen, thanks!
Thank you, means alot!
Amazing ❣
Very nice video! Thanks
GREAT job
Very helpful! Thumbs up.
Great Video. Thank you
Amazing video.
Nicely explained
Thank you for making this video. Succinct and informative. Very helpful.
You're very welcome!
Another option is Sigma 18-50 for video shooting. You can use lighter gimbal and eliminates the re-balancing after lens changed.
Thanks!
Thanks for this. Really informative. I was wondering about my sigma lenses on those fancy full frame camera.
Glad it was helpful!
I use Sigma 16mm & 30mm on A7C and it is great for video, for photos you will need FF lenses.
I did some tests between (A) A6400 sigma 16/30, (B) A7 IV sony 24-70 gm FullFrame, (C) A7 IV sigma 16/30 APS-C mode. (B) was sharpest, (A) very close behind, and (C ) unfortunately looks much more „muddy“ if you compare it side by side. My take awaay from it: The image quality/sharpness is directly dependend on the oversampling resolution: (B) 7k, (A) 6k, (C ) 4.6k. That being said, I‘ll use the sigma 16 on the A7 IV without hesitation if I need wide angle slowmo, but if I need the highest sharpness e.g. for cropping in later, I‘ll try to use FullFrame as much as possible. I gotta say, I love how I can use all these lenses interchangeably on E-Mount, gives me the confidence that I‘m prepared for any scenario. Also, if you‘re interested, Using Active stabilitation in FullFrame mode on the A7 IV crops in just enough or very close on the sigma 16 so you don‘t see the vignette anymore, pretty neat ;)
Is the sigma on a7 full frame mode with the active stabilization image still muddy similar to the apsc mode?
thannks for this ! how did you get that drone like shot at the end ?
Glad it was helpful. The last shot is taken from a ropeway
nice video. I saving money for sigma 16mm 1.4 now.
So much effort. Keep it up 👏
Thanks a lot 😊
Extremely instructive video Mukesh!
Very informative
Thank You!
Everything I needed to know. Thank you!
good video :)
I keet it in fullframe mode but i use clear image zoom x1.3
what a great underrated video men! you explain very well in crystal clear english this complex part 3:08
Glad it was helpful!
🔥
Thank you, the video was very useful, I was debating whether to go for this or the Lumix 24mm 1.8mm for my Lumix S5.
How about distortion, would it be more than a 24mm full frame lens?
Less in fact since you are only using the area of the full frame after it's cropped in, where barrel, and pin cushion distortion are both less to start with on the full frame.
@4:40 How did you manage to connect the camera to a drone? Or what drone was used?
Its not a drone shot :P I was on ropeway with my camera
If it is equivalent to a 24mm f 2 full frame, then isnt the sony's native FE 28mm f 2 way cheaper than this? Third party lenses would never come anywhere near to native sony lenses when it comes to the new sony AF systems. Would you recommend?
Yes, the full frame would be better, but, it can come down to size and weight in many circumstances. In my case I own both the 200-600mm G and the APS-C 70-350mm G (105-525mm equivalent) and one is for local and one for travel with my A7 IV. The 70-350mm is tiny and very light weight, the 200-600mm is a beast.
Thanks, this saved me 300£ :D
Sony Zv E10 Me 50mm 1.8 Full Frame Lens Lagega kya
Han lagega 👋🏼 ⭐.. e / fe mount mai sab e mount and fe mount lenses lagega
What you using for audio recording???
Rode ntg
Which one is better rode ntg or rode videomic pro plus ?? Whats your suggestion?
@@Ramizkhanfilms both are good value for the price. But I preferred ntg because of internal battery and bit better quality and ease of use
Sony a7iv or Sony 7siii which the best camera for wedding photography
For photography a7iv would be good as it has 33 megapixels
The s range are designed for video and have far lower megapixel sensors.
Have you tried using the sigma lens im video mode no crop and allow the camera to do the active stabilization crop to see if it’s usable?
Yes in most cases that works 👍 if AS is turned on there's very little to no vignette.
@@MukeshThakur were you able to use f1.4 in no crop mode or will it be f2?
@@TheSidwadhwa Yes
@@MukeshThakur perfect going for it! 1.4 was the reason i stuck to this lens. The price is really great!
Was waiting for you to use clear image zoom to see how wide we can get without go to crop mode. But whatched the whole thing you did not show this.
I use Sigma 16mm & 30mm on A7C. Not for photos but great for video. For example, if you're recording 30fps 4K and doing stabilization in Catalyst Browse afterwards, you don't need clear image zoom crop. Otherwise 1.1x clear image zoom is needed to avoid vignetting (30fps 4k has 1.2x crop default recording).
So 0.2x is what you get (vs apsc). That may not seem much but Sigma 16mm is like having 21mm f2, and Sigma 30mm like 40mm f2 on full frame (Sony A7C), which is great considering the price-quality ratio.
There is only one drawback when using clear image zoom, eye detection is disabled. And if eye detection is required then apsc mode must be used.
Same same.. clear image zoom surely helps a lot. If it works for you then do it 👋🏼 😊
Does a7iv overheat in 1080p 10bit?
No in 1080 it doesn't
how much
Camera for 2.20L
why is this lens only giving a f/2 or f/2.1 equivalent on full frame and not f/1.4? i don't understand why there is a loss in effective aperture.
See for an example that the aperture of your phone camera is f/1.8 but in reality the lens diameter is nowhere close to a f/1.8 full frame lens.
Then how can it be same.
The answer is that f/1.8 in phone is for that small 1/2" inch sensor but when you put that lens infront of a full frame sensor than it is equivalent to f/16 approx.
@@iamakkkshay but for the iphone lens with the iphone sensor, is an f/1.8 aperture still effectively a 1.8 aperture as far as low light and depth of field performance?
@@didgeproject Nope.
You may need something like f/0.08 there on iphone to get equivalent f/1.8 aperture bokeh of 35mm full frame (just for refrence,not to scale).
But physically it is impossible to create such a wide open lens as it might take a lot more space & tons of optical issues as I think that require tons of R&D to fix.
The amount of light is exactly the same, the light transmission of the lens doesn’t change. So it‘s still like a F1.4 on a Full Frame camera, so it‘s still a low light Monster. But because it’s cropped in, the bokeh blurryness is more like a F2 lens
I keep seeing reviewers saying that this lens will be an equivalent of a 24mm, but isn't the 16mm Sigma supposed to be a true 16mm for APS-C crop cameras? Why mention 24mm?
16mm asp-c = 24mm full frame equivalent
16mm x 1.5 when you place on a full frame = 24mm (what the video again, it is all explained very well)
