I normally bring both my Canon and Sony when I do portraits, mainly a trust factor with my Canon, but I decided to do all of these with just my a6500. I also found out that I have eye AF when using the Canon 24-70 f/2.8 II, bonus!!!

Very nice.

#2 is a great concept, but the image should just be on the wall (not on floor) to give it a convincing graffiti look.

100-400 was actually pretty handy in Disney. The weight was comparable to the 70-200, and I was really impressed with the optical quality. I'll need to add one of these to my kit one day

Regarding the idea of using the RX10 IV as a birding lens...
A couple questions.
1) It's 24-600 "35mm equivalent". So that means that the crop factor is already applied, right?
2) It's f/2.4 - 4. Has the crop factor been applied to that? Is it really f/6.5 - 11 (assuming a 2.7 crop factor)

I've read (I think on this thread) that the huge megapix of the a7riii is an advantage when birding as the photo can be cropped a lot more.
I would lose this advantage with the RX10 having a mere 20 mpix.
Or, with 600mm, I won't need to crop as much?
My concern here is I may not be able to stay on a bif when at 600mm.

I'd love to hear anyone's perspective on this!!

1) yes
2) no. Crop doesn’t affect aperture I.e light gathering ability. F/1.0 is always f/1.0. However it does effect dof

Edit - to clarify point 2 , a 24mm f/1.2 crop lens (assuming 1.5x Sony crop) is equivalent to a 36mm f/1.2 full frame lens in terms of focal length and light gathering but it will have the apparent dof of a 36mm f/1.8 full frame lens

I haven't quite internalized this yet... so, when a lens is considered "fast" this refers to it having a wide aperture, but can a lens that has a physically smaller hole to let light in be as fast as one with a larger hole? Won't I actually need less light to get a photo at a particular ISO with the a7riii/100-400 at f/4 then with the rx10 at that same ISO?

Same light =same settings.. but you will typically get cleaner files on a larger sensor

You need to separate the speed of a lens with dof as that’s where the confusion happens. If you shoot at iso 100 for 1/125th second at f/1.2 with the (made up) 24mm f/1.2 crop lens on a crop body and then mount it on a full frame the settings for the same photo will still be iso100 1/125th f/1.2 for the same exposure however it will have the equivalent framing of a 36mm Lens and apparent dof of a 36mm at f/1.8

The reason it’s confusing is that you mostly relate aperture to dof when discussing lens speed but aperture is primarily the amount of light that gets let in

Holy crap. Got this for the office. Never imagined it would be this big (or heavy!) I wanted to get it out and play with it tonight, but it's too big and heavy. So I"ll just wait till tomorrow.

And I was supposed to get my Loxia 21mm tonight, but it hasn't scanned since 11pm last night at USPS and I already got my mail today. :(

The splash/macro table has been upgraded with channels that allow the drip machine and/or the backdrop to be moved
for or aft depending on need.
This is the set up where we flashed the background only and no flash directed at the drops.

So I just had my first interaction with Sony Pro Support. I know fans of other companies always put down Sony's Pro Support, but I was expecting it to be fine. I'll be honest. It wasn't a very good interaction, and I'm not impressed at all.
