There would have to be some major improvements over the current 100-400 + TC performance for this to be a viable option. As far as IS, Tamron's VC (vibration control) is excellent. I do agree that Canon focusing will likely be faster and it that the Canon will be lighter. But if I have to spend at least twice as much for the lens, plus more for a decent TC, it just doesn't add up, for me. I suspect that the same will be true for many birders on a budget. There will be, however, great deals on used samples of the current 100-400 regardless.

I think even the current 100-400L with 1.4x is quite good optically, at least in the center. I've used mine for moon shots with stacked 1.4x TCs and it's still very good optically even with the 18MP crop sensor behind it.
So, to me, the question is, are you willing to pay double for a lens that's smaller and lighter, has better handling, has better AF, and can get to the 100-150mm range versus the Tamron, if the optical quality is better over the 150-400 range and just as good over the 400+ range at f/8? I think many - myself included - would be willing to do that. In fact, this possibility is the very reason I have not bought the Tamron. If the Tamron were as good at 600mm wide open as it is at 400mm wide open, that would be another story. But it's not.
pknight said:Lee Jay said:pknight said:A new 100-400L was what I was waiting for, but no longer. I suspect that if it is ever actually produced it will cost at least more than twice the $1069 price tag of the Tamron, and it will still stop at 400mm.
I think it will stop at 560mm, with a 1.4x TC attached, and likely be better at 560mm f/8 than the Tamron is at 600mm f/8. From what I've seen of tests, the Tamron really needs to be stopped down to f/8 at 600mm or there isn't much advantage over what you get at 400mm from the same lens.
So, it'll be 100-400/4.5-5.6 and 140-560/5.6-8 versus 150-600/5-8. And I'll bet the Canon will focus faster, be smaller and lighter, and have better handling and IS. And at twice the cost, of course.
But, we'll see if it happens or not soon enough.

And prefer even 540PPI if I can get it.

pknight said:Marauder said:Just wondering, how do you find Servo AF accuracy (and speed) with the Tamron?
I may be a bit slower. There were some AI Servo problems with early samples (achieving focus, not maintaining focus) that have apparently been addressed by firmware updates in later samples. Compared to the 100-400 I do not see any evidence of decreased accuracy. The 100-400 is no gem in that regard, in my experience.

3) Lenses - starting to loose to Sigma and Tamron as these 2 companies started producing high quality lenses, which match or in some cases exceed qulity of Canon lenses (e.g. Sigma 50 mm 1.4 Art, Tamron 24-70 2.8 VC) for affordable price.
rame5hra0 said:According to Thom Hogan, the sensor is unlikely to all that revolutionary, but merely a reworking of dual pixel technology with improvements mainly in autofocus. Not so much in IQ.:

"I think that’s likely more dual-pixel focus ability, only better integrated into the calculation engines this time. In other words, I expect the sensor change is mostly about focus performance, especially with video and Live View".
When I jumped ship from Olympus to Canon, the choice was Canon or Nikon.

Losing is a tough way to put it. Being #1 means you have many mouths to feed -- not just enthusiasts and pros in a forum. I'm truly curious to see what chunk of Canon's business folks like us in this forum (and like-minded shooters not in this forum) actually represent to them.
Also, advances in one small segment of the photography world does not make Fuji, Olympus, Sony, Sigma and Tamron the 'team to beat'. It means that they have had success in one small segment of the photography world. That's all.
And lest we forget, the company arguably most revered for its innovation and 'firsts in the industry' -- Sony -- can't seem to understand photographers well enough to produce a top-to-bottom well thought out camera that is free of non-trivial flaws. They seem predisposed to come up with something cool and useful (that I might want!), shoot it out to the market half-cocked, and under-deliver. What's worse is that they don't seem to learn from this, and they just shoot out another version in record time with similarly iffy results.
So it's more than who is on a roll or has the best team or most innovative pipeline -- I want the company that most consistently satisfies its customers. Bleeding edge innovation isn't my driver. I want a camera/system that does exactly what I want it to do. Canon may be slow, but they have never let me down with what they have delivered.

Quite right. I use the 100-400 and the 7D and AF is generally good, but not always. I'm glad to hear they've addressed the AF accuracy issue as it's the one thing that worried me regarding the Tamron as a possible addition to my kit.Thanks for taking the time to answer!

As things stand today, for my purposes everything about the Canons is superior to the Nikon and Sony offerings except for the sensors and I expect the gap to narrow drastically or even disappear soon.
Look at the clues...
Clue #1: Canon sensors are inferior to Nikon/Sony. Everyone knows that. You can bet that the people at Canon know that too.
Clue #2: Canon executives have hinted that something big or revolutionary is coming.
Clue #3: The 7D2 has been delayed for "production reasons".. We know it isn't just making another copy of the 70D sensor with a few more or less pixels.. it has to be something else.
Clue #4: The delay is NOT DPAF. It is here and in production in the 70D. Being a lower cost camera and stocked and sold in general consumer stores, it is a safe bet that 70D sales will exceed that of the 7D2 AND the entire FF lineup. A bit more for a 7D2 will not matter.
Clue #5: Canon has sensor fabrication facilities that work on much finer lithography than the APS-C and FF sensors of today. Pick up a Canon P/S camera for proof....
Clue #6: P/S sales are declining and this means extra capacity is opening up on those finer lithography production lines...
Clue #7: We know that by going to row or column A/D on the sensor that they could drastically drop noise and increase the DR of their sensors. You can bet that Canon knows this too.
My bet is that the delays in 7D2 production are due to moving the A/D onto sensors with finer lithography. This has to happen at some point and now is the logical time. I would expect a rapid refresh of the FF lineup after this.
