600mm, 1/250, f6.7, ISO 400, hand-held on a 5D. Not a birder. I'm happy (except for the crop...)

Nice shot K, was this at the fair?

Q for you - since you are using a 5D with this lens, would your prior Sigma 150-500 @ 400mm have yielded a similar field of view and image quality?
Do you feel this lens surpasses the IQ of the Sigma?

I think the Tamron would be the equivalent FOV, and equal or slightly better IQ. The Sigma/K5 seemed just too slow to AF, such as at airshows. Funny thing, I got a used 40D in anticipation of using it with this lens, but in any non "M" shooting mode, I have to set the EV at -2, which is not really enough. I think it is a compatibility issue between these 2 pieces of gear. It's fine on the 5D. And metering in M is fine on the 40D.

Interesting about the 40D, maybe sell it and try another model with crop sensor?
Love the rain, we need more of that. Shot 2 is excellent!

A few quick shots from Sunday's match. I'm transitioning over from using the Canon 100-400mm to the Tamron. The latter fills the frame much better, but the former has better tracking AF. On more static shots the difference in AF quality is notably closer. But I've never used a third-party lens that can match or exceed the OEM for things like predictive AF. Still, I'm very pleased with the Tamron, especially for the money and the reasonable weight. The forthcoming Sigma 150-600mm is significantly heavier which one can feel over hours. But if its optical quality exceeds the Tamron then I'll check it out as well. Same goes if Canon actually releases a new version of the 100-400mm next week.

There is some consensus out there that the Tamron lens is optimized for a FF camera; for me, the quality dropoff with my 7D is apparent, but not abhorrent. The reach is still super.

Though I've only used the Bigma on a Pentax K20D, from what I've seen and read, the Sigma 150-500mm lens is a couple of notches below this Tamron, especially in tracking AF.

For this match I had contrasty morning light which helped keep the shutter speed up. For these longer focal lengths, with IS disabled, I've been happy with 1/3000-1/6000. With good light I'm comfy with ISO 800.

It's one photo op I won't be taking up.

I take your point Larry - rodeos have been introduced here, although there are far fewer than in the US. Rodeos are opposed by just about every animal welfare organisation in Australia, e.g.:
What is the RSPCA view on rodeos? - RSPCA Australia knowledgebase
Rodeos // Animals Australia

When my finances recover, I may do the 70D which has a rotating LCD that would be useful. But more than that feature, I would like focus peaking which Canon does not do in any DSLR - for use with the tilt and shift lens. Unfortunately, the Magic Lantern cardware with this added feature does not work with the 40D, 5D or 70D :-(

I actually wanted to see the pee wee rodeo like last year, when the kids pulled the ribbon off the goat's tail, and rode pony-sticks around the barrels. Unfortunately the junior rodeo started at 8 AM though the gates did not open until 11AM :-(

(Tamron 70-200, probably cropped a bit)

i have Pentax DA*300 +1.4TC

i have also Tamron 150-600mm canon 70 d
i use more Pentax DA*300 +1.4TC more.......

Tamron 150-600mm+ canon 70 d are heavy and image quality better with pentax

[Miguel]

The heaviness is expected of a zoom with that focal range, and IS.
Could you please post some example shots that back up your experiences? Were you shooting static or moving subjects?
Thanks,

Interesting. No K mount, though, at least not yet.
