Here it is, the Sigma 18-35mm 1.8. This is my first time doing a lens review, and I’m not gonna cover anything on sharpness,as I believe if you had done enough research.. I will leave the sharpness review to other reviewers 🙂
My purpose with this lens is a replacement for my Canon 17-55mm. Side-by-side comparison. Both without weather seal 😦 I suspect, since Sigma release this version with a quite-reasonable price tag of US800+, I believe they’re gonna release a weather seal version some time with a higher price tag.
My first test is on macro, with my custom-built DIY 60mm extension tube with electric contacts! Please check out my DIY section. Unfortunately, the design of this lens will not be able to focus anything closer with ~10mm extension or less.
1. MACRO TEST – Comparing with Canon 17-55mm
The 18-35 is very decent at macro, one of the weakness of 17-55mm.
In case you’re not familiar with metric scale… here’s a laptop keyboard, shouldn’t be that far from your keyboard.
2. Full frame test
At both 28mm and 35mm there’s some vignetting on the full frame. However still quite usable. Picture of my sister’s dog.
3. Real world samples on APS-C

After 1 week of tests, I absolutely LOVE THIS LENS! I didn’t believe in ‘all-in-one’ lens and always carry a few at my disposal. I love shooting with prime, but still keeps my 17-55mm zoom for some cases. However with the Sigma 18-35mm, I feel I had found the perfect walk-about one lens for all. Big aperture.. standard focal length.. decent macro.. very good sharpness.. you got it all right’here! For the first time I am going out with just one lens attached and not worrying about covering 80% of the shots I want. This is definitely a keeper.
The focus is a bit annoying though, take a pause before it starts moving, hopefully this can be fix with the Sigma’s USB docking station. Heavy, of course. Feels like aluminium and plastic for some area, doesn’t feel very comfortable for the weight balance with 7D and 60D. Losing of the 1mm from 17-55mm? Nah that’s a small trade-in. Looking at breaking the legendary Olympus 14-35mm 2.0, I do want to make a greedy wish that somebody else can come up with a 24mm-full-frame-equivalent wide angle zoom with a F1.8.

I published my first lens modification in 2010, received 100’000+ views on youtube, got viral with the DIY tilt-shift lens on PetaPixel and I did not make any money from sharing the reviews and DIYs… not to mention the many failed DIYs that left me with many dead camera/lens corpses.. So please support me if you have the ability! Any amount is appreciated!
