p.11 #1 · Tamron 150-600 AI Servo sequential shots only
I was interested in this lens for air shows, but I'll hold off until I hear reports from the Nikon/Sony camp. I sold my 5D3 (for a different reason) a few months ago, but still have my glass and a 70D to maybe try the new Tammy on if they get their act together.
It would still be cheaper to pick up a nikon crop sensor (new or used!) and this Tammy than a BWL if everything doesn't work out on the Canon side, but does for Nikon bodies.
*keeps fingers crossed*
I might rent it in the meantime and see how it performs on my 70D (at the local nature preserve) and A7(r) (at the zoo where BIF isn't priority).
Also, my first time reading the 11 pages in this thread and I'm getting a vibe that people need to relax.

Here I am back with more Sea Gullc. These have amore detail than the first ones I posted and I like them. Tare em up if you want but they'er my best so far. BTW: I took Tonys advice on these and used TV mode 2000 SS and Auto ISO. It made it a lot easier for me,.

How far away. How much post processing?
Thanks looks good.
I am surprised you are not reporting AIServo problems like others have.

With a bird flying perpendicular to the camera even one-shot mode works fairly well. People were suggesting to use the 1D MKIII in this way during its AI-servo problem phase.

The bird was probably 30-40 yards away and the only PP I did was defalt NR, and a little sharpening with Helicon Filter. The reason I haven't reported a problem is I always figured it was because I shake and usually can't keep the spot even with expansion on a bird to get sequential shots.

I really hope Tamron gets off their ___ and gets the bugs out of this lens. It is disappointing to me that they have not made any sort of statement to that effect. I really want to try it again. It's size and weight were so much nicer to deal with than the other choices to get to 600mm. I know some people think expectations are too great given the cost, but I just don't agree. All current and recent cameras that it is marketed for should be expected to work properly. If not, it should be marketed as such. It would be alot more understandable for 10 year old cameras to perhaps have some difficulties, but not cameras still being sold like the 7D or sold in the last 18 months like the 1DIV.

A “note” on the AF of this lens with a 7D:
I just received my copy late yesterday, and only had time for initial set-up, and basic tests such as Front/Back AF, etc.
When I test for Front/Back AF, I line-up on a “typical” 45 deg. “target”, focus manually, then turn the focus ring CCW to front focus slightly---take a few shots--- then, turn the focus ring CW until it's back-focused slightly & take a few.
I found that when the lens was “slightly” front focused it would repeatedly “snap” into focus—BUT--, when it was back-focused to the same degree it would/could not squire AF at all, even when I manually adjusted it closer to the correct position.
This was with C.Fn iii-4 set to (1)/ Focus Search=Off; which I had selected to keep my 100-400L from hunting in “grossly” out of focus situation.
When I changed the setting to Focus Search= ON, the Tamron was able to achieve AF from both directions however, when coming from a FF position it “snapped into focus—BUT--, when coming from a BF position it had to “hunt”/“cycle” to find it. The position of the Focus Limiter made NO difference.
The above behavior was both in One-Shot and IA-Servo.
I never experienced this anomaly with the 100-400L, or Sigma 120-300 OS even with a 2X TC attached, and C.Fn iii-4 set to (1) Focus Search= Off.
So, with my copy of this lens, there's an apparent problem squiring AF from a Back-Focused position.
Weather that's inherent in the design, or a malfunction, I'm not sure, but it didn't happen with the Canon or Sigma lenses, so it's not likely a 7D “problem.
I'll be taking it out today for some field shots, including some IA-servo BIFs .

I was advised to contact [email protected] who is thecommunity coordinator and manage Tamron’s social media accounts. I was given her contact information because I posted a few negative remarks on Facebook. She quickly gave a non response when I contacted her.
Tamron is failing big time.

I'm still going to wait for an affordable replacement for the venerable 100-400 from Canon. There's far too many negative observations and reports on this lens for me to consider it.
