How's the Canon 24-70mm F4 on an 80D?

Looking to upgrade my Sigma 24-105mm ART to a Canon 24-70mm F4 for my 80D. Mostly because of better IS, faster AF and it being more portable.

Heard and read great things about its image quality on a crop camera, but I'm looking for personal experiences of users here. Is anyone having problems with it suffering from focus shift (residual spherical aberrations)? How do you like the lens overall?

Seems like an odd choice for a crop, so i doubt there are that many people that would bother putting it on their camera

All these lenses are very good.

The question is what focal range you need and other features.

24mm is wide enough on APS-C for you?

AF was slow for you on an ART lens?

Very best,

Yes 24mm is wide enough for me as a walk around lens as I carry a 10-18mm with me aswell. When I want to go wide, something that starts at 17 or 18mm isn't wide enough anyway.

AF isn't particularly slow on the Sigma 24-105 Art, but it's missing that Canon snappiness and responsiveness that I really like. Other than that the lens performs fantastically on a crop camera, better than the Canon 24-105L I used to own.

Then you have lots of options.

The 24-70 F4L IS is a great lens regardless of sensor size, as long as you like the focal range, it's less heavy than the F2.8 flavors, it's not a tiny lens, but it's not a huge brick either.

I take it you have you no interest in the 18-135 STM or 24-105 STM?

I was surprised how snappy and good the AF is on the 18-55 STM. Dead silent, and just as fast as anything else with USM that I've used. Impressive. Though I know not all STM lenses have the same AF mechanism; I know the STM motor of the 24 STM, 40 STM and 50 STM are not nearly as fast as the 18-55 STM and they're louder.

Very best,

I would get the 24-105 f/4 over the 24-70 f/4

Effective reach on the long end is approx 160 vs 110

I use it on crop regularly. Not sure what the 24-70 mfd is, but the 105 is pretty good for an inexpensive zoom.

No not considering either of those STM lenses, but thanks. I have previously owned an 18-135mm STM and while it has great features and zoom range, I found its image quality to be lacking too much for me. I've spent a lot of time thinking what would be my next lens and it seems like the 24-70/4 is the best option for me right now.

Thanks, I have previously owned the 24-105L, but had problems with Err01 and I like the idea of the more modern 24-70/4 with better IS and improved image quality. It also has a much lower MFD using its macro mode, which results in a 0.7x magnification (vs. 0.23x on the 24-105L). Curious about that as well for those random macro shots.

You know there is a new 24-105 f/4 now?

Apparently not a huge upgrade over the first version, but no doubt some improvements.

Yes, I'm aware of that and would love to own the new version, but it's way out of my budget.

Maybe I'll upgrade to that in a few years, when more of them show up on the used market.

I know it's an older design..... but at one time, we had two 15-85's. We still have the one my wife uses on her 70D, you know, the one she "inherited" from me.

Anyway, it isn't ultra wide... but was always wide enough for me.. nice range for a crop camera. I'd still have mine but it doesn't work with a 1D IV.

You can pick them used up for a decent price these days. Just a thought.

Yes, I have owned that lens as well (I go through a lot of standard zoomlenses ). I loved it for its versatility, but found the corner sharpness to be disappointing. Too bad..

My wife is a kitchen designer. I've photographed many of her kitchens in various stages of installation with the 15-85. We must have two above average lenses because I didn't notice a huge drop off in corner sharpness. I know others have complained about that too so I'm sure there is a lens to lens variation.

I now use the 16-35 f/4 IS for that stuff. I shoot at f/8 on a tripod and truth be told, I haven't noticed all that much difference. I thought I would. I did just get new glasses... so that isn't it. I'll have to do a comparison sometime..... pixel peep a bit.

if you didn't like the IQ of the 18-135STM...not sure if the 24-70f4IS is that much of a step up...

doesn't look any better than your 24-105A either...

without stepping up to one of the f2.8 zooms, i'm not really sure where you can go to get significantly better IQ...and those sound like they are out of your budget

Not really looking for any image quality improvements over my Sigma 24-105.

But that comparison you linked is not really fair, since it's known that the 24-70/4 has a weak spot at 50mm and the 18-135mm performs at its best at 50mm. Selecting other focal lengths show significantly better image quality from the 24-70/4 over the 18-135 STM.

You might not be looking for IQ improvements, but the 24-70 f4 would certainly be a downgrade compared to the 24-105 Art. I find it highly doubtful that you will find anything with a price tag that would make getting rid of the Art reasonable. My guess is you're almost certain to be losing money for a few milliseconds of AF speed.
