Sigma 18-35 f1.8 review

@tony: how is the situation 9 years later? Just waiting for my used copy. I will use it for milky way shooting. How did the kit lemses evolve over the generations.

Eye-so,,,,, STOP THE MADNESS.
"I S O"

do you like sigma better than tamron

so i need to buy a full frame camera

Is that a Notorious B.I.G. drinking glass ? With fancy straw ? Cool,

If not this lens, what is the best portraiture lens for APS-C camera (T7i)?

Watching the video after 7 years, still makes sense though. Going to buy this lens. Thanks Tony for such a detailed review 😊

Excellent review!!

WOH. I did NOT know the crop factor also impacted the aperature!!! I tend to shoot FF but also keep a 7D for that little extra 1.6 factor reach. SO this won't work on an FF ?

Hello : I have Canon EOS Rebel T6i - Can I use f1.8 for 1/100 ISO 100 for family picture (2 to 8 people) inside house with low light condition? If not what would you recommend the setting for sharp picture for a family picture (2- to 8 people)?

I just bought a second-hand lens for my Nikon D3300. While mounting, I feel a lot of resistance. Can that be a problem that might damage the lens or the body?

Watching this in Dec 2021, the lens is still doing well in most reviews ☺️👍🏽 planning to get it with an adaptor for my Fuji XT-4

I miss evil mustache goatee Tony.

Hi Tony, question.. I've seen many comments about the Sigma 18-35 focus issues. Do you know if this has been corrected. I would love to buy this lens you recommend but am concerned about this problem. Thank you so much for your time and work. I have three of your books and have learned much from you. Thank you!!

Can you advice me how this lens will perform on a Canon R6? Thanks

Even after so many years of waiting, lens did not got cheaper nor any better replacement!
I am using Nikon d5500 with kit lens and 50mm prime lens.
Need something for indoor photography as 50mm is sometimes difficult to use

How well does it work wide open at 18 mm for astrophotography?

Is it a good choice for Nikon D5600?

I want to know how good these lenses are

The f/value of a lens does not change no matter what camera it is used on. Full frame or C-chip or 3x4 censer. Where in God's name did you come up with the f/value needs to be multiplied by the crop to full frame factor. That is wrong at all levels.

Tony two issues plz answer, one why u have to set iso on a higher side for full frame thats 1600 iso when you said crop body let less light in compare to full frame? I mean 1.8f on crop should let equal light in as 2.8f on full frame. Secondly focal length, why crop had 35mm and full frame had 70 when its should be 35mm and 56mm (35*1.6) on crop and full frame respectively. Please explain these two points.
Thanks for a great video✌️

Kit lens: AHHHH, CHROMATIC ABORATION
Sigma 18-35: what? huh?

@Tony & Chelsea Northrup does Sigma 18-35mm f/1.8 have visible distortion and vignetting on Nikon D7500 camera?

Should I not buy this lense if I already own the 18-135 mm ?

You want to improve your film making - invest in lens. All cameras are pretty much the same and talking about focal lengths and crop sensors is a load of crap. Buy the right lenses, frame your subject and keep shooting until you're proud of the results. Oh and forget shooting photos and video they dont make you money.

Can you tell me the sweet spot of this lens for video?

Sigma 18-35mm f/1.8 DC HSM + NIKON Z50 + NIKON FTZ = AMAZING! AF SPEED VERY FAST & support EYE AF~~~ HAPPY it CAN BE USE ON YEAR 2020

hi, how about stabilizer?... the lens and the camera doesnt have stabilizer.... nikon and canon doest have...on DSRL APSC...

This man is brilliant, tels it as it is

Amazing! Thanks for this!

Applying crop factor to f stop only works in order to achieve the same DOF and noise ratio, NOT THE SAME EXPOSURE, or else light meters would include a crop variable. Please do not miss inform viewers. A FF camera set to "X" settings WILL HAVE SAME EXPOSURE as a MFT camera with same "X" settings. DOF and NOISE RATIO won't be the same.

Did you try the sigma 50-100?

Thanks
Didnt realize that crop factor also applies to aperture

Sigma sharper than canon L lense

Sorry Tony, NOT all of us are Multi Billionaires or we just don't want to get a "2 or 3 digit NIKON"..

I'm torn between sigma 16-35 1.8 or Canon 17-55 2.8 is usm? Alot of folks having focus issues with the sigma

Can we get tony as a bond villain please

"An 2.8 becomes an f4" That is just really incorrect. I shoot with a crop and a full frame simultaneously and I use the same lenses on both, crop and full frame lenses. The settings are always the same to get the same result.

is this lens good for landscape? Thanks

Great review doc

Tony, thank for the review. I recently purchased the Nikon D7500 and am looking for a lens that won't break the bank for some golf course photography. I am looking for a high level of sharpness and like the f1.8 if I need to shoot in early morning or late evening light. I'd love to hear your thoughts if this lens is a good fit. Thanks, Jason

Why is the F-Stop on an APS-C lens on an APS-C camera body, also multiplied by the crop factor? E.g. Canon M50 with the Sigma 18-35 f1.8. Also, has Sigma improved the focus pulling on this lens, as I wish to shoot indoor sports. Additionally, with the Viltrox speed booster work on this lens?

Can i use this lense on 5d mark iv ??
If yes then what changes it will make ??
Thanks in Advance

I can't believe it is a true f/1.8 for APS-C, this lens is like a dream. I saw this video years ago, but I couldn't appreciate at the time how good this lens is.

Man, I LOVE this lens, I've had mine since 2014 when I was shooting with a Canon 7D. I then sold my 7D to test the waters with mirrorless, so I bought a Sony a6000 and the Sigma MC-11. It has served me well, but I just upgraded to a Sony a7iii, and need a new wide prime to replace it with. Luckily I already had a Sony FE 85mm f/1.8.
If only Sony or Sigma made a 24-70mm f/1.8, I would jump all over that.

Thank you so much. I'm buying right now!!
