Cannot decide on a 24-70mm lens. If you have tested the other brands please share your experience.

06-05-20 Update: Thanks for your help everyone.
I called around then drove out of state and purchased the Tamron SP 24-70mm F/2.8 Di VC USD G2 lens. Model A032
The Tamron demonstration model auto focuses fast and sharp. Once the stores camera body diopter was adjusted everything / auto focus looked great almost magical.
Maybe there are alternative lenses for my needs. I need something to handle indoor and outdoor activities. Dim candle light during Christmas concerts at church preferably with no flash. Update: I was about to give up and get 2 prime lenses for the price of one 24-70mm
I read about so many tests and reviews and videos for 24-70mm lenses sharpness, color aberration and the comparison lists seemed to go on forever.
Read a few reviews and tests about 4 brands so far. Can. Tam. Tok. Sig. It doesnt seem to matter what brand I read about.
There appear to be a few and sometimes a few too many complaints about one problem or another.
Complaints seems to be about back and front focus, soft and not sharp images, lens ribbon failure, slow AF or OS lens stabilization.
A longer warranty, a great looking metal lens and USB dock appeals to me or impresses me.
If the image is good or better than the reviews and tests are saying I have no problem buying a 3rd party brand.
I have strong hands and a little extra lens weight will not bother me.
$1500 is a chunk of money to spend. Seeing a few complaints was the frosting on the cake for me.
I did get to hold a rental Tamron 24-70mm connected to their 6D Mark 2 (same body I own)
The Tamron lens physical quality on that camera body felt great.
Maybe a little more comfortable than the Canon 24-70mm ii lens body.
The Tamron 24-70mm locked focus fast enough for me.
I didn't notice much much difference in AF speed.

anyone complaining about the canon is a dodo

Any complaints about a lens focusing system having an issue almost always involves a camera body that is to blame. You can adjust for it with AFMA or with sigma art, use the dock to adjust even more granularly.

Can't go wrong with Canon or sigma these days.

Any one complaining about sigma art is a dodo.

I will complain about the Sigma 24-70. I tested it against my Canon 24-70 V2.....Not even remotely close in performance in low light conditions....My assistant had one....very soft at F/2.8...not close to canon for sharpness at F/2.8....missed a lot on the dance floor...she sold it and got a Canon

Sigma 24-70 is not as good as the Canon 24-70......End of conversation from head to head testing

If your in the market for a zoom get the canon

BTW- sigma primes are very good - 85mm, 105,, 135mm at among the best available.

Buyers need to educate themselves because all primes and zooms are in their own league for performance and results

You can definitely go wrong with Canon, why do think they came up with AFMA? Sigma allows for more adjustment on many of their lenses, exceeding what AFMA can do from Canon as well.

Of course we know the answer to be that both a body and lens can be to blame, this why both AFMA and the sigma dock exists. Also, the dock exists to customize lens functions and to provide firmware updates as well.

Focusing issues of a lens on a dslr is primarily the fault of the body anyways. Get a mirrorless and most of these inaccurate issues go away since the sensor is the AF engine and the lack of a mirror removes most of the errors we have had in the past.

If you were looking at the Tamron, I did a review after 2yrs of ownership.... https://photography-on-the.net …showthread.php?​p=17402054

AFMA usually refers to the Canon menu item 'AF Microadjustment'.

Tamron has a Tap-in Console that allows you to make more adjustment than what the camera body allows.
It also provides some other customisation and allows you to do firmware updates if required.

Settings regarding MFA are stored in the camera body for individual lenses.
Using a console, settings are saved in the lens and will be used for any body you attach it to.

Recent Tamron 24-70 lenses:
Tamron SP AF 24-70mm f2.8 Di VC USD
Tamron SP 24-70mm f/2.8 Di VC USD G2

Only the G2 is compatible with their console.

Prior to my post I had read the lowest ratings for several lenses.
I did get to hold a Tamron 24-70mm connected to their 6D Mark 2 (same body I own) The Tamron lens physical quality on that camera body felt great.
Maybe a little more comfortable than the Canon 24-70mm ii lens body.
I may seriously consider the Tamron lens IF the image quality is right up there neck and neck.
A few people paid the extra money for brand name claimed that an internal lens ribbon cable or something failed and produced an Error and their lens had to be sent back for repair.
Do I really need to spend More Money for several years of care warranty?
I really don't know if the newest production dates have that issue. If not I will pay the extra $599 or whatever for name brand.

It seems your technique for reading reviews is to only focus on the worst. Any product can have the occasional lemon as any thing mechanical can fail. A better way to look at it is that the rate of failure is very low so look at the performance and assume that failure is not likely.

I had the EF 24-70 2.8 II. Excellent lens. What I have read about the RF and the examples I have it is every bit as good if not better. Fast and you get IS. As stated back and front focus not an issue on mirrorless. My RF 24 24-105 F4 is sharp (exceeded my expectations) and the 24-70 is better.

Since I had a EF 24-70 2.8 II I had a though time deciding between the RF 24-70 and RF 24-105. I didn't need the speed anymore and the range was more suitable for what I do these days. I wouldn't think twice about the RF 24-70.

Wow. I totally didn't notice that model. Not sure it it will work on my EOS 6D Mark2. If so would a factory fresh import be a bad gamble or bad idea? RF 24-70mm f/2.8L IS USM Lens $1896 compared to EF 24-70mm f/2.8L II USM $1500 I still have not worn out my fresh 1 year old EOS 6D Mark 2 body yet. It would however make any transition to mirrorless later better.

I wouldn't hesitate to purchase the EF 24-70mm f/2.8L II again.

This “Dodo” can complain......... No IS.... why?......

I've been using the Tamron G2 version for the kinds of things u were planning. I've had zero issues in low light, no focus issues. I use it for anything and everything and when I'm walking around the city after dark I use it exclusively so I don't draw as much attention to myself. Attached image was taken with it.

Try tracking a moving couple in the dark or a reception on a dance floor at 8000 Iso and then tell me how you like it. Canons version 11 never misses and its never slow to focus on moving subjects

I use it for worship services and events in low light at the church, never had any issues. Oh, and I never use flashes for my captures like yours had.
