TAMRON SP 24-70mm F/2.8 Di VC USD G2
« on: September 21, 2017, 05:34:57 PM »
Decided to pull the trigger and got one today. So far so good. Requires some AFMA (roughly +10) on the tele end, but the AF seems to be consistent and very fast. Need to run through FoCal and probably adjust via the Tamron console. The VC feature is truly awesome. While it's irrelevant for portraits, for still life / landscape / nature shots in dim light it's very helpful. 1/10 @ 70mm no issues whatsoever.

Wondering if anyone else got this lens? Please share your experience.

Update: @ 70mm AF is consistent if I'm shooting / calibrating at a certain distance. If I move, my AFMA needs to be adjusted. Most likely the lens requires recalibration for multiple distances (via the console), which seems like pain in the b@tt to me. I simply don't have time for this. I thought that's more like an old Sigma lens behavior, didn't expect it from Tamron. The lens is going back to the dealer on Monday :'(

Jopa,

Just get the Canon 24-70 II L instead . the price difference is negligible. AF consistency of Canon lens is spot on though. I recently had to recalibrate my Sigma 120-300 F2.8 Sports and it took me nearly 3 hours as I had to calibrate at 16 points in total.

Alex, you are fast! It would take me a half of day probably.

Yes, that's the plan. But I'll be missing VR, seems like a very cool feature.

Yep, VC feature is cool. Let me share my experience with Tamron 24-70 VC and I am hearing this has not been fixed in G2:
VC has to be switched off if you shoot with faster than 1/70s shutter speed or you get all your images blurry.
My problem is:

1. I kept forgetting to switch the IS off when I had to
2. You may find that light condition changed quickly by a stop or two and your shutter speed crossed into faster than 1/70s territory. When you run and gun and shoot in Av mode it happens a lot.
I discussed this issue with Tamron  support engineers many times and they admitted that it is what it is.

Again, I read that this still being an issue with G2 as well

Bottom line is: you will be better served with Canon 24-70 II L glass. It is a stellar glass.

It happens every time I decide to save some $ and go with a different brand :)   At the end of the day I'm coming back to Canon LOL.

Just got this lens today after a lot of research.  Amazing VC!
I put it on my 5DS and shot a handheld at 1/8th, f2.8, 24mm, ISO 800

Seems pretty good.  Low light lock was fast and nailed the focus without any lens/AFMA adjustments.  Tap-in console was free with the lens through B&H.

Even @ 70mm? You're lucky! :)

I wanted to love this lens, I really did.  I purchased my first copy from Adorama.  The lens had horrible front-focusing issues and after hours of calibrating with the TAP-In Console and FoCal, I sent it back because it still was front focusing from 50mm-69mm.

I got a second copy from Adorama and it also had some front-focusing issues at apertures smaller than F/2.8, even with live view on my 5DS R and DPAF on my 5D4 w/C-Log!  I also spent hours calibrating with the TAP-In Console and it made the performance worse!  What an epic waste of time!!!  This time, I sent the lens to Tamron along with my 5DS R and 2 weeks later, I thought it came back perfect.  Turns out, the 24-70 G2 worked perfectly at all apertures only with the center-most auto-focus point however, it was inconsistent with some of the 40 outer af points on both bodies.  Even the other center auto-focus points left me wanting with this lens.

At this stage, I can see why some may still use this lens because the auto-focus accuracy was excellent at the center point and "ok" everywhere else however, I'm used to getting great accuracy at any auto-focus point with any aperture with my native Canon lenses. I bought this lens in place of the Canon 24-70 2.8 II for the VC however, I like my lenses to be accurate above anything else.  Just to make sure I wasn't going crazy, I also tested my Tamron 15-30mm (3rd Copy) at all auto-focus points and apertures and it works like a charm, no worries what so ever like a native Canon lens.

If my 2nd copy of the Tamron 24-70 G2 was just as accurate as my Tamron 15-30, I would have kept it however, I spent almost 2 months calibrating and shipping the lens back-and-forth to Adorama and Tamron to get the best performance possible.  In the end, my patience ran out and I nabbed a refurbished Canon 24-70 2.8 II at 15% off while I had the chance.

If I got blessed with a perfect copy of the Tamron 24-70 G2, I would hang on to it for dear life because I had a Canon 24-70 2.8 II before it was stolen and both lenses have fantastic AF speed and Canon's IQ is only marginally better than the Tamron.  Even though the Tamron is noticeably weaker at 2.8 than the Canon, at 3.2 and above you'd be hard pressed to tell the difference between the 2 in real world usage.  The only reason I sent the Tamron back is because I don't have time to waste on finding the best copy, while I know I can get a great copy of the Canon easily.

Other than AF accuracy, my findings were similar to Dustin Abbots results here:
