TL/DR version -- it's brilliant ...provided you don't use that 1.4x (bold below is my emphasis):

"If you decide to use the teleconverter, though, the situation is quite different and MTFs - distinctly lower. Resolution decrease is noticeably sharper than in the case of other contemporary, expensive, high quality telephoto lenses cooperating with a teleconverter. I admit the performance fell short of our expectations; we thought that such an optically complex teleconverter, designed to cooperate with just one model of lens, would perform much better than traditional, external devices which, after all, are supposed to fit many professional telephoto lenses of a given system.

As a result, even if the performance at 550 mm cannot exactly be called weak, as the results allow you to enjoy fully useful, good images, it is not something we expected from such an expensive lens."


Ouch.  They don't typically report T/C results and we have no Canon 200-400 1.4x review at LT to compare to, but they went so far as to say above that traditional modular T/C use on a good telephoto lens does better, not worse, than this dialed-in and fixed T/C does.  That's somewhat shocking.

The 550 EX is long discontinued, and likely can't be repaired by Canon.  Take that into account.  You don't know its history or if its been repeatedly overloaded.  In the USA, if I buy using many major credit cards, they double the warranty, so thats another consideration.
The downside to Yonguo is compatibility, every new Canon model seems to break compatibility, and its months before new firmware, if ever.

Lenses / Re: 70-200 2.8 with 2x tele vs 100-400mk2 with 1.4 tele

Right -- I didn't mention that I was using the 2x III teleconverter.

Also, TDP has combinations of all sorts of these bodies + lenses + TCs at the IQ tool I posted earlier, including (if you choose the 1Ds3 as your body) multiple copies of each lens to compare.

But a test chart only tells you so much.  AF speed (esp. if teleconvertered) can vary quite a bit.  I'd rely on the birders/wildlifers here as well as the various sites that specialize in those types of photography.

I hope this version of the G7X finally comes with software on both the camera and iOS/Android that can wirelessly transmit RAW photos.  The RX100 series have had a way to do this for a few models now. Lightroom mobile has RAW shooting functionality for iPhones and Android phones that are a couple years old.  Fooling around with cables and, worse, the phone interfaces to copy these pictures from a camera is just too much time and trouble for 99% of the cases where I quickly want to get a RAW image to my phone for processing in LightRoom mobile. Too often, if I really want a RAW image while out and about, I just shoot it with my iPhone.

I’d happily pay for G7X mark II specs with wireless RAW right now.  If the mark III comes out without wireless RAW, I don’t see the point of the camera.

In September after I got my G7X II I took an extended trip through the Rockies. I don’t recall ever shooting JPEGs at all with that camera. Sometimes in the evening I would use Canon Camera Connect to review pictures from the day on my iPad. As I recall I transferred a few to the iPad, and maybe with a bit of editing I emailed some on to friends. From what you say, I shouldn’t have been able to do that. I wonder what I really did.

What I said was fooling around with cables and the phone interfaces to copy RAW images from a camera while out and about is too much time and trouble for 99% of the cases where I want to quickly get a RAW image to my phone.

The case you are describing is completely different - you are doing this in evening after you have returned to where you are staying and doing this with an iPad with a larger screen than a phone in a more convenient setting for that.  I'm talking about doing the transfer to a phone while out and about. It's technically possible to hook up the cables and navigate the interfaces, but a pain - especially if trying to do while standing or walking. Using the wireless app for Jpegs, it's easy. I want this functionality for RAW images.

I already have a great pocket camera for shooting RAWs that I can pull images off at home if that's what I want.  Sony has already had options to pull RAW off their RX100 series via wireless for a few years now.  If Canon will not include it this time, I don't see the point of the camera.

As I recall the Canon software works the same on the phone as it does on the iPad.  If you are away from a Wi-Fi signal, the camera will make its own network for the phone to connect to. I’ve never had a cable that would connect the phone to the camera, so I don’t know what you were doing with one, just that I didn’t need it. Bluetooth probably works also, but I haven’t tried. As I said, I don’t shoot JPEGs with that camera, so something must work with the RAW files. I just don’t remember what I did. As you say, the iPad has a bigger screen, so I use it to sort through pictures when I’m back at the hotel.

The main reason I use the Canon software on the phone to connect to the camera’s Wi-Fi is for the camera to get the GPS info from the phone to add to pictures’ metadata. I don’t do that on a long day of touring in order to save battery on both devices.

The Canon software does work the same on the iPad as on the iPhone and when you try to transfer a RAW photo (even if you only shoot RAW rather than RAW+jpeg) it converts the RAW image to jpeg (or it extracts the smaller jpeg image that is stored within the RAW format).  It does not transfer a RAW file.  You can check that by checking the file format and size of image copied to the iPad.  Different software tools like Adobe Mobile Lightroom will also tell you what format an image is when you import them.

Lenses / Re: 70-200 2.8 with 2x tele vs 100-400mk2 with 1.4 tele

I know Art Morris looks at the 70-200 f2.8 with 2x tele as a decent kit for bird photography - but make sure you get the mkiii version.
The 100-400 is no bigger but with a 1.4 you get 560mm if you do need it. The 100-400 also has a significantly shorter minimum focus distance.

A lot depends on if, after the Galapogos, you will find the f2.8 really useful; also if the reasons you bought the 150-600 in the first place are still relevant.

+1 on the 70-200 f/2.8L IS II + 2x being less than ideal -- a native 100-400L II would mop the floor with it at 400mm.

But for this photographer who is capped at 200mm (that 70-200 is my longest lens), having the 2x option is a lovely one for the once-a-year boat ride with the in-laws.  :D

But if you regularly bird, wildlife, etc. surely you should get a proper longer instrument that doesn't require the use of a 2x.  The 100-400L II is certainly the right call until this supposed 'affordable long zoom' arrives from Canon, but you can also look at the 400 f/5.6L if you want to save some money (no zoom, no IS, but it's cheaper).

If you want to have some fun with your focus peaking, m42 lenses, ef-m camera, and tilt shift, try this thing: https://www.adorama.com/katspxseosm.html

I have the Nikon mount version of this, it's really quite fun with old Nikkor manual-focus lenses such as the 50mm f/1.4 and the classic Nikkor Micro 55mm f/2.8
