A lot of people are going on about it not being 24... but the fact that they kept this so close in weight to the 24-105 f4 makes it amazing for me. If I need 24 then I'll often want to have a 14-28 on anyway.
If they'd made it 24-105 f2.8 it probably would have weighed 500g more and cost $600 more, and then people would complain about that. Unless you're going to go and make your own 14-300 f1.2, then just accept that this is an incredible lens.

this feels like christmas. 2 review videos from gerald one after another!

[andrewtregoning]

insane specs, lenses are just so good these days, I love it

[rhalfik]

Sigma dock software can tune focus sensitivity. Maybe not as detailed as video people would want, but you can make the focus throw longer.

After watching all the reviews in YouTube when it come to buy a camera or light or lens its GERALD UNDONE review matters😍

My new Sigma 2.8 24-70 arrived a few hours ago and I already opened the box! I'm crying! Waaaah! This is very usable focal range, negating even the Sony 70-200 I bought a few months ago. With this I could go from 12-24 (+APSC mode), to 28-105, and then jump right on the 100-400. Eliminating TWO expensive Sony lenses in the process. Damn you Sigma!! ;)

Sigma isn't playing around. Love them. Great to have so many good options.

I would love to see a comparison with the Tamron 35-150mm f2.0-2.8mm

[StefanGlazer]

There is something to be said about Sigma, I honestly have stuck with them and their art series for years now. I still shoot a 7D Mk II and my "daily driver" 18-300mm F3.5-6.3 MACRO. It always seemed to be minimal with Chromatic Aboration. At 300mm it is by no means the sharpest, but the pricepoint always blew me away for 500 bucks US, I have a wide arrange of work I've done with that lens that I have sold large prints of, and am always stunned how they looked to similar shots with my Canon Primes and Zoom/Telephoto lenses.

Now, I will pine as no one makes new EF EF-M mounted lenses (because why would anyone?), but awesome and in-depth as always! I love seeing new offerings like this!

[TristanPerry]

Was looking forward to this, this is such an exciting lens considering the focal lengths and aperture 😊

[jamesbridges]

Perfect doc lenses, I could leave this on my Burano/FX3 all day

[ecmjr]

Aside from the insightful review, the outro of the bee changing color was artsy cool. Nice!

[borysmaster]

As usual. Great and detailed review 🙌🏼 down, thank you

[TechMixr]

Damn he’s on fire lately ladies and gentlemen!

[klaymoon]

This would been an amazing video lens if it was stabilized.

[CrispyJacketStudios]

6:33 I would usually usually zoom in to max first to get focus then adjust from there on a parfocal lens to give it the best chance of maintaining. Once you set it at 105 then zoomed back out. It was sharp. Out of interest, once you zoomed back in again, was it still sharp again or was it just losing focus somehow on zooming in?

[verebellus]

i was literally looking for a lens like this yesterday and sigma heard my calling

[MikeMarrah]

Now I just need to decide between this and my 35-150...

[danielruff]

does someone know, why or when he switched back to the "old" setup? Because he tried the "night show" style one a view months back. But I never heard him talk about why.
But thanks for the Video! Nice as always
