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!
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 RUclips 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.
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 ;)
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
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.
Almost quite right. There's a small issue because you presented the sensor as a 16:9 sensor, something the a7 IV does not have. The sensors on these FF cameras are 4:3 and as such cover a 4:3 area. Video covers a 16:9 area of that 4:3 area, which is why a Crop lens may or may not be more usable on FF, because you may not have enough for 4:3 but almost enough for 16:9, eg see 18-35 by sigma
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.
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
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.
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?
Brother you cleared my all doubts

Also, in FF mode will you be able to use 1.4 or will it be 2.0 only?

Is the sigma on a7 full frame mode with the active stabilization image still muddy similar to the apsc mode?
this videos sure clears up a lot of doubts I've carried about my sigma 16mm - thank you for being so thorough and detailed!

thannks for this ! how did you get that drone like shot at the end ?

Another option is Sigma 18-50 for video shooting. You can use lighter gimbal and eliminates the re-balancing after lens changed.
Almost quite right. There's a small issue because you presented the sensor as a 16:9 sensor, something the a7 IV does not have. The sensors on these FF cameras are 4:3 and as such cover a 4:3 area.

Sony a7iv or Sony 7siii which the best camera for wedding photography
For photography a7iv would be good as it has 33 megapixels

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
