90D + Tamron 150-600 g2
9

Played a bit more with my 90D in the last couple of weeks and overcame a few of the initial challenges I had with focusing and proper exposure.

I find that +1/3 or 2/3 is usually necessary when I tended to go -1/3 on the 80D. I still find BIF challenging but most probably due to my technique and the Tamron may be being a bit slow or off AF wise. I use 9 points AF and weirdly the lens (or camera?) sometime picked the sky slightly above the bird (in the same 9 points group) rather than the bird....im not sure how to deal with this other than using a single focus point but then it makes catching the bird almost impossible...

Also, how do you guys use the joystick and back button focus at the same time? I like the joystick but had to revert to make the shutter do the focusing too.

Anyway, here is an example of a good shot I got in the garden tonight. ISO5000 cleaned with Topaze Denoise AI (which is amazing) then edited in LR

Anybody else using the Tamron 150-600 g2 for BIF?

Very nice shot. I have this lens/camera also. Just recently acquired the lens so havent really run it through its paces yet. I have briefly tried BIF with more misses than hits.

It's my experience that the Tamron G2's focus isn't fast/efficient enough for most BIF. There are limits to a $1000 600mm lens. I have managed to get some decent photos of larger birds (like sea birds, birds of prey) against a clean background with this lens. If you are going after flitting songbirds or hummingbirds, well, good luck.

Dan

Ive got the same set up and will say it is an improvement over my 80D. I went ahead and upgraded my 55-250 to a 70-200 2.8 L II and after seeing the results premium glass makes in image quality I will be trading in the G2 for a 100-400L II next.

Check if AF works with live view with the 90D.

I have the G1, which was sent in for the first available factory firmware update sometime in 2014, I think, and AF will not work in Live View. In the live View LCD screen, it says manual focus in the upper left, regardless of the position of the switch on the lens.

Yes I have a 70-200 2.8 too and it is a great lens but too short for birds.

Im considering the 100-400 too but Im not sure the AF would be that much quicker with an 1.4 extender? I find the 150-600 image quality very good on stationary or slow moving subjects. I just need a faster AF lens.

Anyone tried the 100-400 with a 1.4x on the 90D?

AF is not just about f-number. There's the fastest an AF drive can move, and there seem to be other optical variations which seem to affect AF.

The Canon 100-400 II seems to be one of those lenses that AFes much better than the f-number would suggest, compared to other lenses.

My 400/4DO II with the 90D pops into focus with the 2xIII at f/8 faster than my Sigma 100-400 at 400/6.3, even with 1.26x the f-number, and even in low light. I like the Sigma optically, but in deep shade shooting dark things, the AF takes much longer.

I recently made a thread on the canon lens part about my rebel and my tamron 100-400. The lens is amazing for image quality very happy, and the reviews put the sharpness at same as the canon 100-400 L ii in the centre.

However, yesterday there small birds flying directly towards me. I know my rebel isn’t the best (45 PT AF), but I switched to the efs 55/250 and got much much much more hits using the same technique and camera settings.

It did make me wonder too, whether a canon 400L zoom would do a better job.

Birds moving across the frame I’ve had success with, but a small owl flying towards me head on and the tamron got 0 hits. The 55-250 had say 25% hits.

Hi all,

Trying to figure out whether I am making mistake or if the Tamron 150-600 g2 is not good at fast moving subjects, or if it is a 90D issue (unlikely i think).

I used AI Servo and ITR is turned off

for both examples I was using 9 points focusing and the camera/lens seems to have chosen to focus on something else than the actual moving subject.
I can may be understand the confusion on the first example as the background is busy (although it is not in focus either but anyway) but I can't understand why the blue sky would be prioritised against the bird that is across 2 points and more contrasty than the sky?

I had another example, which I can't find anymore (may have deleted the shot) where the bird was across 5 points but the focus was 'acquired' on the top 3 points which was blue sky

Am I making mistakes or is the Tamron 150-600 g2 rubbish at catching moving things?
Would I get better results with the Canon 100-400 ii and 1.4x TC? I understand the 100-400 has better AF but not sure how much the converter affects AF speed

Thank you

I am using the 100-400ver2 +1.4 extender ver3 and can't say enough about the IQ detail. However the focus rate on a small bird on a branch is not that good. Even with center spot focus it will often focus on the background. I have been using AI servo and AI focus and the rate is about the same. I didn't have much of a problem when I was using the 7D mk2. Any suggestions that would help focus on small targets would be helpful.

Focus distance - 75 yds.

Photo distance - 75 ft.

Photo distance - 60 ft.

Photo distance - 50ft.

Leaves are sharp but the birds head isn't.

Re: 90D + Tamron 150-600 g2

Great shots, well done. Nice IQ indeed.

The last one where the leaves are sharp and not the bird, are you able to see what focus point was used by the camera in DPP?

No, This was a jpeg photo and I didn't open in DPP.

The Tamron G2 is not the best for tracking fast moving objects. I have had good success with birds against the sky, but not against busier backgrounds. I see this as a good lens for more static subjects. It can give astounding results within its limits.  Not sure a direct comparison of the 150-600 G2, and the 100-400 L II + TC, is reasonable given the 2x price differential. You get what you pay for.

I am curious why you disabled iTR -- it's specifically designed to help with tracking, after all. That's what it does.

Dan

The rumor is that iTR causes OVF AF to look for faces with the metering sensor, impeding AF when there is no face to focus on.

Yes I agree the 150-600 g2 is a great lens for static subjects, I got really great sharp results with it. Even with slower moving subjects like surfers etc.. 
I understand the 100-400 is double the price but if it is a lot better than the Tamron then I might just get one... but I don't want to get one if the AF performances with a 1.4x tc are going to be just as bad as the Tamron.

I disabled iTR as the manual says it can slow down the focusing, which is not what I want for fast moving stuff. My understanding is that iTR also specifically looks for faces and can get confused when he doesn't find any. I saw a video of a guy showing how iTR was focusing on random faces instead of his subjects while he was shooting football. He fixed the issue by disabling iTR.

I am going to rent a 100-400 ii this weekend and see how it performs with my 1.4x tc.
Lucky in Sydney there is shop that does short term rentals

I was having the exact same problem with my Tamron 150-600 (1st version) on the 90D. Stills were often good. Anything moving, not so good.

One day, I took out my 6D with the lens and was reminded how well the combo works, compared to the Tamron 150-600 + the Canon 90D.

Ended up returning the 90D. It's a lovely camera, but I didn't want to purchase an expensive lens in order to enjoy it. Esp when my 6D works so consistently well with the old Tammy.

Re: 90D + Tamron 150-600 g2

Hi -

I don't have the G2,  but I had the G1 from when it was released (I got one of the early copies and had the firmware upgraded). I used this lens with my 6D, my  70D (now sold), my 80D, and my 7DM2.  I also have the 400 mm f/5.6L (non IS lens) , the 100-400 mm f/4.5-5.6L mark 2, and the 400 mm f/4 DO mark2. I have borrowed from Canon the 500mm f/4L IS II, and the 600 mm f/4L IS II.

That G1 I had was simply rubbish at shooting BIF on any Canon body I owned.  Even though it got me to 600mm, I just could not tolerate using it for BIF. Now, for perched birds on a FF body at the 6D, it was much better. And it could make sharp images at say 300mm (it was not sharp at 600mm f/8 but it got better at around 560 mm f/8, but still could not match any of the Canon lenses (even the 400 mm f/5.6L is sharper).

So, my bottom line was I used it has a tool and avoided using it for BIF and just used it for perched birds during migration until I got the DO, as the f/4 proved to be a killer feature for me.

Maybe your G2 is better, but I'm not spending my money on one.

Good luck.
