Was curious if anyone here has gotten the new 90D yet and taken it for a spin? I'm about to take the plunge myself (upgrading from my T3i), and would like to hear first-hand impressions before the dive. Thanx!

Have you read the review of the 18-400mm on TDP? I had tried out in the past 2 copies of the Tamron 18-400mm and found both rather soft in the centre at 400mm with terrible CA further out, in agreement with the review. The 90D needs sharp lenses to take advantage of its sensor. I tried the ultra zoom again as one was in the shop where I bought my 90D to see if maybe it was a better copy, but no luck.Update: Yesterday, I took the plunge and ordered the 90D along with a Tamron 18-400 f/3.5-6.3. I also bought (on Saturday) a used Canon 17-40 f/4 L from a pro photographer/old acquaintance of mine. These will go along with my pre-existing 70-200 f/2.8 L USM, my Nifty-50, and my old EF-S kit lenses. I'm hoping to also buy the 100 f/2.8 L Macro lens later this year.
I'll be testing out the new gear at an event called Aussie Nationals in central CA the first weekend of November.
What are the alternatives to get such a range jn a single lens though?The 90D needs sharp lenses to take advantage of its sensor. I tried the ultra zoom again as one was in the shop where I bought my 90D to see if maybe it was a better copy, but no luck.
If you want to have an 18-360mm range (TDP measured it to be 360 and not 400mm max) at the expense of blurred and CA images at the long end, then it is your choice. The OP started this thread to get advice on his purchase based on our experience, and he now has some more info. He has some shorter zoom, and he could go for a 70-300mm STM for a good longer zoom or even an EF-S 55-250mm, which are both excellent. It’s for him to decide according to his wants.What are the alternatives to get such a range jn a single lens though?
Since the OP is coming from a T3i, the upgrade to a 90D should be significant enough to feel worth it even if the lenses used don't allow it's full potential to be realized. The upgrade from my T3i to an 80D is certainly worth it for the AF and ergonomics, but the sensor is just so much better, regardless of resolution. Doing heavy edits on the T3i shows flaws really quickly. On the 80D you at least have to go into the extremes to notice them. I haven't looked for them, but I have also not seen any accounts of banding with the 90D.

So is leaving it at home because switching between or carrying multiple lenses is no option for a trip you take.Putting any 20X zoom lens on a 32+ MP camera like the 90D is a waste of a 90D.
It's a great camera even with poorer lenses, but you'll get the best out of it with good lenses.
By writing that, you are missing the lesson that the overall MTF of the sensor plus lens varies with the MTFs of each in different ways, and an OK lens doesn't improve much with increasing sensor resolution but a good or excellent does. Here is a good article from lensrentals explaining why: https://www.lensrentals.com/blog/2017/10/the-8k-conundrum-when-bad-lenses-mount-good-sensors/The latter half of that sentence is true for any camera that isn't a complete junker.

Brandon Dube shows how the overall MTF of the system with an excellent and even a good lens drops significantly as the quality of the sensor decreases, but "With just an OK lens, the resolution of the sensor makes a lot less difference than it does with a good lens. Increasing camera resolution makes far less difference in the system MTF. "
What you said previously was indeed only half the picture.Yeah, what I said is only half of the picture.
In essence the camera+lens can only be as good as the weaker of the two (a close first approximation. On a really crappy sensor you'd probably still see some small difference between a cheapass lens and the finest thing ever made). If the sensor is junk the lens won't matter much. If the lens is junk, the sensor won't matter much.
If you're thinking I'm still not "getting it" at this point I guess I'll have to ask you to be more specific as to what I'm missing.

I was in London for a quick business trip recently and brought my 80D + 35mm 1.4 Art. Between the light rain and colleague I was walking around with, switching would have been an annoyance. It's my favorite combo, but for such a trip, a zoom might have yielded less hassle. If that's a worthy trade off for the quality you lose is up to the individual.
It's not like the OP didn't list a bunch of fine lenses for use with the 90D as well.
